Honeybees
Honeybees can do three kinds of jobs.
It is one of the most unusual insects in the world. Bees are special because they divide up their honeybee work. Each bee has a certain job to do.
The busiest bee is the worker. Workers build the nest, called a hive. Inside the hive, workers make a honeycomb from wax(蜂蠟). They store honey there for food. Workers are always cleaning and fixing the hive. They even stand at the opening and fan their wings to cool the hive. Worker bees will attack anything—even people—to keep their hive safe.
Another kind of bee is the drone(雄蜂). Drones are male bees, and their job is to fly with the queen bee and mate with her. After the queen mates, the worker bees drive the drones away. The drones then starve to death.
The third kind of bee is the queen. Each hive needs only one queen, and her job is laying eggs. She can lay as many as 2, 000 eggs a day.
小題1:The bee’s nest is called a _______.    
A.hive B.honeycomb C.drone D.wax
小題2:Which jobs do workers do?
A.They lay 2, 000 eggs each day and build a nest.
B.They mate with the queen bee and then starve.
C.They clean the hive and keep it cool.
D.They attack the queen bee.
小題3:According to the story, bees _______.  
A.a(chǎn)re very dangerous insects
B.will attack anything or anyone to protect the hive, if necessary
C.a(chǎn)re like any other insect that flies
D.eat each other as food
小題4:The drone is driven away when its job is finished, because _______.  
A.it attacked the workersB.it is no longer needed in the hive
C.the queen bee has diedD.it ate the queen bee

In order to know a foreign language thoroughly (完全地),four things are necessary. First, we must understand the language when we hear it spoken. Secondly, we must be able to speak it ourselves, correctly with confidence(自信) and without hesitation (猶豫). Thirdly, we must be able to write it. We must be able to make sentences that are correct in grammar.
There is no short way to succeed in language learning. A good memory is a great help, but it is not enough only to memorize the rules from a grammar book. It is no much use learning by heart long lists of words and their meanings, studying the dictionary and so on. We must learn by using the language. If we are pleased with a few rules we have memorized, we are not really learning the language. We must “Learn through use”. Practice is important. We must practise speaking and writing the language whenever we can.
小題1:The most important things to learn a foreign language are      .
A.understanding and speakingB.hearing, speaking, reading and writing
C.writing and understandingD.memorizing and listening
小題2:Which of the following is the most important in learning a foreign language?
A.A good memory.B.Speaking.C.Practice.D.Writing.
小題3:“Learn through use” means       .

Forty-two of the fifty American states offered some kind of public online learning this past school year.One state,Michigan,now requires all students to have an online learning experience before they finish high school.Even the idea of a school has changed since the rise ofthe Internet in the 1990s.
A new report from the Center for Evaluation and Education Policy at Indiana University says eighteen states have full-time virtual schools.There are no buildings.All classes are online.
Florida started the first statewide public virtual school in the United States in 1997.Today,the Florida Virtual School offers more man ninety courses.56,000 students were enrolled as of December.Almost sixty percent were female.The school's website says each student was enrolled in an average of two classes.
Florida Virtual School has now opened the Florida Virtual Global School.Students in other countries pay for classes.Janet Heiking teaches an English class.She lives in Indianapolis, Indiana.Her students live as far away as Africa and Japan.She says they are taking her Advanced Placement class to prepare for attending an American college.They can earn college credits by passing the AP test.
So how good are virtual schools? Studies have shown mixed results, as a new report from Indiana University notes.For example, students at Florida Virtual School earned higher grades than those taking the same courses the traditional way.And they scored higher on a statewide
test.But virtual school students in Kansas and Colorado had lower test scores or performed at a lower level than traditional learners.Studies also find that virtual schools may not save much in operating costs.
Education experts say the mixed results suggest the need for more research to find the best ways to teach in virtual schools.A1so, they say schools of education need to train more teachers to work in both real and virtual classrooms.
小題1:A virtual school is one that___________.
A.is set up after the rise of the Internet

Most people hate change, which is sad since we often go through intense changes in life. And for some of us, even the smallest changes can upset our day. So the question is: Why do most of us find making adjustments to our lives so hard?
Fear of change is nothing new. Over a century ago, the Parisians were unhappy over a particular addition to their city: the Eiffel Tower. In fact, the citizens were so angry about the plans for the tower that they protested its construction. As strange as it may seem, their anger was completely natural. They were given no choice about the huge change that was going to be made, so they became angry.
But we get upset over changes even when we do have a say in the matter and think about them carefully. Changes are brought about every day by the decisions we make: which school to attend, which job to take, whom to marry. Voluntary changes also make most of us uneasy because we don’t know how those changes will affect our future.
People have discovered that the key to overcoming the fear and anger associated with change is to be flexible. When they are flexible, people can adapt to new situations more easily. Being flexible is especially important in the 21st century as technology makes change occur faster than ever before. Those who oppose change, especially with technology in the workplace, may find themselves out of a job.
When change comes, and you have no choice but to face it, embrace it. A positive attitude helps a lot. In fact, the change may turn out to be the best thing for you. That new job you got may end up being much better than your old one. You may make the best friends of your life in the new city you moved to. Don’t merely focus on how you feel about change; instead decide to accept the change. The change is the reality, and it’s up to you whether the change will be a success or a failure. You never know your next change may be your lifes Eiffel Tower!
小題1:Why did the building of the Eiffel Tower make the Parisians unhappy?
A.Because they didn’t like the design of the Eiffel Tower.
B.Because they couldn’t avoid accepting the Eiffel Tower.
C.Because it was no use building the Eiffel Tower.
D.Because the Eiffel Tower seemed strange.
小題2:According to the passage, it can be inferred that what won’t disturb us are _____________.
A.the changes that have agreement with one’s will
B.the small changes we meet in our daily life
C.the changes whose effect we can predict and control
D.the changes that we discuss or consider thoroughly
小題3:How should we overcome negative emotions that the changes bring?
A.We are not supposed to face the changes and let them alone.
B.We should actively accustom ourselves to the new circumstance.
C.We should not take the changes seriously and avoid them as much as possible.
D.We should know that the changes merely bring us bad influence.
小題4:What does the underlined sentence in the last paragraph mean?
A.The change will probably make you fail like the Eiffel Tower.
B.The change is like the Eiffel Tower which is not good for our future life.
C.Your future life is never known just like the Eiffel Tower unknown to the Parisians.
D.Your future life is likely to be a great achievement due to the change.
小題5:What is the best title for the passage?
A.The Psychology of ChangeB.The ways to Overcome the Fear
C.Changes That Disturb UsD.The Bad Effect of Changes

A Southampton University team found that people who were vegetarians by 30 had recorded five IQ points higher on average at the age of 10. Researchers said it could explain why people with a higher IQ were healthier as a vegetarian diet was connected to lower heart disease and obesity rates. The study of 8,179 people was reported in the BritishMedicalJournal.
Twenty years after the IQ tests were carried out in 1970, 366 of the participants said they were vegetarians — although more than 100 reported eating either fish or chicken.
Men who were vegetarians had an IQ score of 106, compared with 101 for non-vegetarians; while female vegetarians averaged 104, compared with 99 for non-vegetarians. There was no difference in the IQ scores, between strict vegetarians and those who said they were vegetarians but reported eating fish or chicken.
Researchers said the findings were partly related to better education and higher class, but it remained statistically significant after adjusting for these factors.
Vegetarians were more likely to be female, to be of higher social class and to have higher academic or vocational qualifications than non-vegetarians. However, these differences were not reflected in their annual income, which was similar to that of non-vegetarians.
Lead researcher Catharine Gale said, “The findings that children with greater intelligence are more likely to report being vegetarians as adults, together with the evidence on the potential benefits of a vegetarian diet on heart health, may help to explain why a higher IQ in childhood or adolescence is linked with a reduced risk of coronary heart disease in adult life.
But Dr Frankie Phillips of the British Dietetic Association said,“It_ is_ like _the _chicken  _and _egg. Do people become vegetarians because they have a very high IQ or is it just that they are clever enough to be more aware of health issues?”
小題1: What’s the result of the research mentioned in the text?
A.Intelligent children are more likely to become vegetarians later in life.
B.Children with a higher IQ are less likely to have heart disease later in life.
C.Intelligent children tend to belong to higher social class later in life.
D.Children with a healthier heart tend to have a higher IQ later in life.
小題2:It was found in the research that________.
A.most of the participants became vegetarians 20 years after the IQ tests were carried out
B.vegetarians who ate fish or chicken were of similar intelligence with strict vegetarians
C.female vegetarians were more likely to have higher annual income than non-vegetarians
D.vegetarians were more likely to have higher annual income than non-vegetarians
小題3:What does the underlined sentence in the last paragraph mean?
A.Intelligence is linked to not just being a vegetarian but to many factors.
B.The rate of getting heart disease is linked to your lifestyle.
C.The link between a high IQ and being a vegetarian is still uncertain.
D.The link between a healthy heart and diet remains to be proved.
小題4:What’ s the best title for the text?
A.Get more IQ points!
B.Be a vegetarian, please!
C.Vegetarian diet cuts heart risk
D.A high IQ is linked to being a vegetarian

Intellectual property (IP) is a product of the mind that has commercial value. The concept dates back to 1623, when the first patent law to protect IP rights was passed. IP rights protect an artist from having his/her creative ideas copied by another. For example, if somebody generated an idea for a novel, that idea is protected by IP rights. If someone else wishes to represent the idea or develop it further, he/she must consult the original artists, who will normally be rewarded financially for its use. Back in the 17th century, IP rights were primarily carried out to protect newly developed manufacturing processes against stealing, but today intellectual property rights are also enjoyed by those who create music, art and literature.
In recent years, IP rights have been the focus of a great deal of discussion because of a technology which looks set to weaken them altogether: the Internet. Many years ago, if you wanted a recoding of a song, you would have to purchase it from a music store; if a novel, from a book store. In those days, IP rights were easily protected since it was very difficult to obtain intellectual property without paying for it. However, a lot of IP, including songs, films, books and artwork, can be downloaded today free of charge using the internet. This practice has now taken the world by storm, dramatically affecting the way in which we view IP rights.
小題1:According to the writer, in the beginning, IP rights were mainly of use to _______.
A.those creating music, art and literature
B.novelists
C.those not receiving financial reward for their work
D.engineers and inventors
小題2:What do we know about the Internet according to the passage?
A.It does not affect the way we understand IP rights.
B.It sells songs and films.
C.It makes IP rights harder to protect.
D.It prevents the production of artwork.
小題3:According to paragraph 2, what has “taken the world by storm”?
A.Intellectual property rights.B.Free downloading.
C.The Internet.D.The large number of songs, films and books.
小題4:A possible title for this passage could be _______.
A.IP Rights and Our Attitudes B.Ways to Protect Your IP Rights
C.The Present and the Future of IP rightsD.A History of IP Rights

Work your brain!
Between 2 and 3 pounds of wonder,it controls everything we say,do or think,who we are and what we care about. The way we walk or laugh or figure out things. What we like and the talents we possess. How we see and talk and run and jump and process our food.
The brain uses 20 percent of our body's oxygen and 20 percent of its blood. Somewhere within its protein,fat, 100,000 miles of blood vessels and 100 billion nerve cells,it helps us remember where we put our gym shoes. Change our temperature so we don't die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orange­flavored drinks.
Its intricacies(復雜性)are stunning,far beyond anything most of us can imagine. To keep this work of art as polished(有光澤的) as possible we need to eat right,exercise and keep mentally stimulated(刺激).
Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone(荷爾蒙)in our brain that improves memory. Mental stimulation keeps you sharp even as you age.
“It's very important that we tell people to be physically active and mentally active,” said neurologist Malcolm Stewart.
“People cannot stop aging,but you're able to reduce the damage;you're able to keep the function up.”
Following are Dr.Stewart's advice for improving brain health:
Nutrition
Avoid fast food. Follow the old adage(格言,諺語):For breakfast,eat like a king;for lunch,like a queen;for supper,like a beggar.
Exercise
Do a combination of stretching aerobic and muscle­strengthening every day.
Mental games
Try to have a sense of hope about the future. Do puzzles. Listen to music. Reach out to others to make their lives better.
小題1:The purpose of the author in writing this passage is to ______.
A.inform us how the brain works
B.give us advice on how to keep the brain healthy
C.tell us that the brain plays an important role in our lives
D.show how special the brain is to us
小題2:The word “stunning” in Paragraph 5 means ______.
A.interesting  B.strangeC.significant D.a(chǎn)mazing
小題3:According to the text,more exercise ______.
A.keeps our mind sharp   
B.helps improve our memory
C.gives our brain a rest   
D.is good for brain cells communicating with each other
小題4:In order to keep brain healthy,we should avoid ______.
A.eating a good lunch B.doing puzzles
C.eating a large supper D.taking aerobic exercise
