Here is an astonishing and signficant fact:Mental work alone can’t make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue(疲勞). To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired.
Some scientists declare that most of our fatigue come from our mental and emotional(情感的) attitudes. One of England’s most outstanding scientists. J. A. Hadfield,says,“The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares,“One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated---those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.
小題1:What surprised the scientists a few years ago?
A．Fatigue toxinscould hardly be found in a labour’s blood.
B．Albert Eistein didn’t feel worn out after a day’s work.
C．The brain could wrk for many hours without fatigue.
D．A mental worker’s blood was filled with fatigue toxins.
小題2:According to the authour,which of the following can make sitting worker tired？
A．Challenge mental work.
B．Unpleasant emotions.
C．Endless tasks.
D．Physical labor.
小題3:What’s the authour’s attitude towards the scientists’ ideas?
A．He agrees with them.
B．He doubts them
C．He argues against them.
D．He hesitates to accept them.
小題4:We can infer from the passage that in order to stay energic, sitting workers need to ______.

Monitoring global warming usually requires a Ph. D. and enough maths to glaze your eyes. But that Francisco Lopez and Ruby Nostrant track（記錄）what climate change is doing to five different plants in Tucson, Arizona and they are only in the second grade.
“We are collecting data because the weather is changing and the plants are blooming,” Ruby explained.
Scores of other students at Borton Primary Magnet School and Sunnyside High School in Tucson are heading outdoors to be part of a new scientific push to figure out how the biological timing of the earth is changing. It’s a research project that the average person, even a kindergartner, can join in.
The National Phenology（生物氣候學）Network is calling on volunteers to help track early spring blooms and eventually changes in animals caused by global warming. It’s called Project Budburst. When it was first open to the public last year, thousands of people participated in 26 states.
“All people can contribute to it by tracking the timing of flowering events or leaf-out events for plants and animals in their backyard,” said Phenology Network director Jake Weltzin. He calls the volunteers “citizen-scientists.”
The idea is that tracking flowers blooming—especially lilacs（丁香）; which everyday people have helped track for decades—is fairly simple. The Website http://www.Windows.ucar.edu/ citizen_science/budburst/index.html gives directions on what to look for in different parts of the country.
University of Maryland professor David Inouye said it’s so easy to figure out what’s blooming that a lack of special knowledge isn’t a problem.
University of Arizona ecology graduate student Lisa Benton coordinated（協(xié)調）the Tucson high school students as they looked at plants five minutes from their high school. Each student has specific guidelines and she’s been happy so far with the data she is getting. For his part, second-grader Francisco said he had fun helping out.
“I like going out in the desert,” he said. “I want to be an Einstein.”
小題1:Francisco Lopez and Ruby Nostrant are monitoring global warming by __________.
A．watching early spring blooms and changes in animals
B．studying the biological timing of earth
C．collecting data of the local weather
D．tracking the early spring blooms of some local plants
小題2:Those who participate in Project Budburst are mostly ___________.
A．ecology college graduatesB．high school students
C．common peopleD．experts
小題3:What David Inouye says suggests that ____________.
A．the study carried out by students is convincing
B．the students still need special training to study climate change
C．it is difficult to study climate change
D．to figure out what’s blooming needs special knowledge
小題4:Who is primary school student joining in the Project Budburst?
A．Lisa Benton.B．David Inouye
C．Francisco Lopez.D．Jake Weltzin.
小題5:We can conclude from the passage that _______.
A．changes in animals caused by global warming happen earlier than those in plants
B．the biological timing of earth is changing because of climate change
C．the effect of climate change in Tucson, Arizona can be hardly noticed
D．all the plants in Tucson, Arizona are blooming earlier because of climate change

In tradition (傳統(tǒng)的) education, the teacher may feel that the students are not very grown up. Usually, teachers are older than students, and teachers feel that students are young and do not know much about the world. The teachers feel that they must tell the students what to do most of the time, and that they must also make the students study specific (特殊的) things. In open education, the teacher’s methods are very different. These teachers feel that the students are human beings (人) first, and students second. They expect the students to be responsible for the things that they do, just as adults are. A student’s ideas and feelings are just as important as the teacher’s. The teacher allows the students to decide what they want to do, and does not make them study what they do not want to. The teacher lets them decide what to study and how much to study. It’s very important for the teacher to show how he or she feels about students.
小題1:Which is the topic for the passage?
A．Traditional Education
B．Open Education
C．The Students Are Human Beings First

Ever since man began to use the telephone, there have been new problems arising from the carrying of messages. At first, each message was carried by a pair of overhead wires. As a result, telephone exchanges were soon surrounded by thousands of wires. The wires were then replaced by cables (電纜)，each containing many pairs of wires. Each cable is capable of carrying many messages. These cables, laid underground, replaced the overhead wires.
The more extensive telephone services have become, the more demand for these services has increased, particularly the demand for long-distance services. In China, for example, this growth is now over 30% every year. Long-distance telephone exchanges are usually in crowded cities, where is not easy to lay new labels for expanding services.
The use of radio to send telephone message and to link all telephone exchanges makes it possible to get rid of overhead wires and some underground cables.
Now man has invented the microwave system ( 微波系統(tǒng) ). In a microwave system messages from various places can be brought together, and then they are sent out and received by radio. After that, the messages are split into their original form. Finally, they are sent to the places where they are going to be sent.
小題1:The word “message” ( in paragraph 1) is close in meaning to “______”.
A．electricityB．industryC．informationD．wave
小題2:A cable is different from an overhead wire, because it ________.
A．is made of wood
B．needs more exchange
C．carries more messages
D．is much longer
小題3:What does the word extensive mean？
A．growingB．usingC．holdingD．understanding
小題4:The best title for the passage would be “________”.
A．The Telephone and Its Past
B．From the Wire to the Microwave System
C．The Needs for Better Telephones
D．How to Use the Telephone

Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know, however, that they existed over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests that wheels for transport didn’t become popular for a while, though. This could be because animals did a perfectly good job of carrying farming tools and humans around.
But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modem road design.
In the mid-1700s, a Frenchman came up with a new design of road—a base layer (層) of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same lime, metal hubs (the central part of a wheel) came into being, followed by the pneumatic tyre(充氣輪胎) in 1846. Alloy wheels were invented in 1967, sixty years after the appearance of tarmacked roads (柏油路). As wheel design took off, vehicles got faster and faster.
小題1:What might explain why transport wheels didn’t become popular for some time?
A．Few knew how to use transport wheels.
B．Humans carried farming tools just as well.
C．Animals were a good means of transport.
D．The existence of transport wheels was not known.
小題2:What do we know about road design from the passage?
A．It was easier than wheel design.
B．It improved after big changes in vehicle design.
C．It was promoted by fast-moving vehicles.
D．It provided conditions for wheel design to develop.
小題3:How is the last paragraph mainly developed?
A．By giving examples.
B．By making comparisons.
C．By following time order.
D．By making classifications.
小題4:What is the passage mainly about?
A．The beginning of road design.
B．The development of transport wheels.
C．The history of public transport.
D．The invention of fast-moving vehicles.

You can’t always predict a heavy rain or remember your umbrella. But designer Mikhail Belvacv doesn’t think that forgetting to check the weather forecast before heading out should result in you getting wet. That’s why he created lampbrella, a lamp post with its own rain sensing umbrella.
The designer says he come up with the idea after watching people get wet on streets in Russia. “once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(傘蓬)built into a street lamp.” he said.
The lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors(傳感器)then ensure that the umbrella offers pedestrians shelter whenever it starts raining.
In addition to the rain sensor, there’s also a 360°motion sensor on the biberglass street lamp which detects whether anyone’s using the lampbrella. After three minutes of not being used the canopy is closed.
According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.
While there are no plans to take lampbrella into production, Belyacv says he recently introduced his creation one Moscow Department, and insists this creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.
小題1:For what purpose did Belyacv create the lampbrella?
A．To predict a heavy rain B．To check the weather forecast
C．To protect people from the rain D．To remind people to take an umbrella
小題2:What do we know from Belyacv’s words in Paragraph2?
A．His creation was inspired by an experience
B．it rains a lot in the city of Saint Petersburg
C．Street lamps are protected by canopies
D．He enjoyed taking walks in the rain
小題3:Which of the following show how the lampbrella works?
A．motor→canopy→sensors B．Sensors→motor→canopy
C．motor→sensors→canopyD．canopy→motor→sensors
小題4:What does paragraph 5 mainly tell us about the lampbrella?
A．Its moving speed B．Its appearance
C．Its installation D．Its safety
小題5:What can be inferred from the last paragraph?
A．The designer will open a company to promote his product
B．The lampbrella could be put into immediate production
C．The designer is confident that his creation is practical
D．The lampbrella would be put on show in Moscow

Some plants get so hungry they eat flies, and even small frogs. What's more amazing is that these plants occur naturally (in special environments) in every state. In fact, they're found on every continent except Antarctica.
You've probably seen a Venus' flytrap -- a small plant, which grows 6 to 8 inches tall in a container. At the end of its stalks (莖) are leaves that act like traps (陷阱). Inside each trap is a lining of tiny hairs. When an insect lands on them, the traps suddenly shut. Over the course of a week or so, the plant feeds on its catch.
The Venus' flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Society's Newsletter. He states although you might have read some science-fiction stories, no meat-eating plant does any danger to humans.
Barry says a plant is meat-eating, only if it does all four of the following: "attract, kill, digest, and absorb" some form of insects. Meat-eating plants look and act like other green plants -- well, most of the time.
All green plants make sugar to produce food. What makes meat-eating plants different is their special leaves, which need insects for one reason: nitrogen (氮). Nitrogen is a nutrient that they can't obtain any other way. Why?
Almost all green plants on our planet get nitrogen from the soil. Meat-eating plants can't. They live in places where nutrients are hard to get from the soil because of its acidity. So they've come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soft is poisonous to meat-eating plants. Never fertilize (施肥) them! But don't worry, either, if they never seem to catch any insects. They can survive, but they'll grow very slowly.
小題1:According to the passage, a Venus' flytrap ______.
A．is a small plant which grows in a container
B．is a kind of plant which gets hungry easily
C．can trap and feed on some form of insects
D．can only grow 6-8 inches tall
小題2:From the passage, we can infer that ______.
A．meat-eating plants are found nowhere else except Antarctica
B．all green plants get nitrogen from the soil
C．meat-eating plants endanger humans in science-fiction stories
D．the nutrient-poor soil is beneficial to meat-eating plants
小題3:Meat-eating plants grow very slowly, ______.
A．so you'd better fertilize them
B．probably because the supply of nitrogen is cut off
C．simply because they can't absorb nitrogen from the soil
D．and then they will die slowly
小題4:Which of the following is true?
A．Meat-eating plants look and act like other green plants.
B．It's hard to get nutrients in the soil when acidity is high.
C．The Venus' flytrap eats flies to get nutrient from them.
D．Green plants make sugar at night.

A. Be brave in your requests
B. You get what you tolerate
C. Don’t feel guilty of your requests
D. Don’t think others are mind readers
E. Don’t make a “no” mean more than it does
F. Be specific about what you want and when you want it
Be Bold: Ask for What You Really Want!
Have you ever been in a situation that is causing you to feel annoyed, frustrated, or unappreciated? We all experience them, but often we don’t have the courage to change them or ask for what we really want. Complaining about your problems never solves them. Only when you get clear about what you want, and are willing to ask for it, will you experience not only a lot less stress in your life, but greater success in your relationship, career and life. Here are five tips to help you on your way.
小題1:________________
We often think our bosses, colleagues and even our friends can understand our thought even without being told. So when they don’t act as we’d like, we feel hurt and upset. For any relationship to develop, both parties have to communicate their needs. Whether it’s how you’d like your colleague to communicate with you about a work project, or how you’d like your boss to assess your work, it’s necessary to convey what you want.
小題2:________________
When asking for what you really want, you will seldom, if ever, be given more than what you have the courage to ask for. So don’t weaken your requests to avoid being turned down. Think about what your ideal outcome would be and then confidently, courageously, ask for it. While you may not always get as much as you asked for, you will get more than you would have otherwise.
小題3:________________
In the workplace, the biggest reason for unmet expectations is a lack of understanding of exactly what is expected. A request that holds water needs to make clear not just what you want, but also the time limit within which you want it. That is, both a clear “what” and “when”. For example, “Could you please get the monthly sales report to me by midday Friday?
小題4:________________
Whether it’s asking your friend to show up on time, or asking your colleague to stop making jokes in your presence, every day, through what you say and do, you teach others how to treat you. Letting others know what you will （and will not）put up with and what you expect from them, is important to your wellbeing and success—at home and work.
小題5:________________
In reality you won’t always get what you ask for. Your boss won’t always give you the pay raise you’d like and your parents may not agree to mind your three kids every second weekend. When people say no, you can take it really personally and decide never to speak to them again—or you can accept it graciously and move on. At least now you know where you stand and can plan accordingly.
Asking for less than you really want—from yourself, from others and from life—doesn’t serve anyone. Remember that fortune favors the bold. So make bigger, better, bolder requests, and ask for what you really want. Who knows…you might just get it!
