More than one in eight U. S. adults finds it hard to stay away from the Internet for several days at a time and about one in eleven tries to hide his or her online habit, according to a study showed on Tuesday.
The study by researchers from the Stanford University School of Medicine in California found one in eight adults admitted they needed to spend less time online, saying this showed "problematic Interact use" is present in a sizable portion (部分)of the population.
The study involved a nationwide telephone survey of 2,581 respondents in the spring and summer of 2004 with researchers then examining the data and preparing the report which appears in the October issue of CNS Spectrums.
The survey found that 68.9 percent of respondents were regular Internet users and 13.7 percent of the users found it hard to stay offline for several days at a time.
It found 12.4 percent often stayed online longer than intended, more than 12 percent said they saw a need to cut back on their Internet use, and 8.7 percent tried to conceal (隱瞞) "non-essential "Internet use from family, friends and employers.
A smaller number, 8.2 percent, said they use the Internet to escape problems or a bad mood, while 5.9 percent felt their relationships suffered because of too much Internet use.
One report published earlier this year said that 5 percent to 10 percent of the population likely will experience Internet addiction (上癮).
It said signs include a disregard for health or appearance, lack of sleep and reducing physical activities and social communications with others, as well as dry eyes and juries of hands and fingers.
小題1:From Paragraph 2, it tells us _______.
A.how to use the interact is a terrible problem to adults
B.how surfing the net has caused a bad result to people
C.why to throw off the Internet addiction becomes a hot problem
D.why so many adults want to spend less time on the interact
小題2:Those who try to hide their habit of addition to the Interact make up of the respondents.
A.12.4%B.8.7%C.5.9%D.13.7%
小題3:According to the researchers, which statement is true?
A.Online habit of people has been a dangerous problem to society.
B.All of the Interact users have terrible psychological problems to solve.
C.The internet is more harmful to people than good.
D.We have to pay attention to negative effects from the internet.

Have you ever wondered why the roots of the plants always know which way to grow—into the soil but not above it? Some British scientists have recently solved this mystery.
It turns out that roots have special hairs that tie them into the soil and help them grow their way past obstacles, a team at the John Inners Center in Norwich reports in the February 29 issue of Journal Science.
“The key is in the fuzzy(有絨毛的)coat of hairs on the roots of plants,” says professor Liam Dolan. “We have found a growth control system that enables these hairs to find their way and to become longer when their path is clear.”
Root hairs explore the soil in much the same way a person would feel their way in the dark. If they come across an obstacle, they make their way around until they can continue growing in an opening. In the meantime, the plant is held in place as the hairs grip(緊緊抓住)the soil.
The hairs are guided by a clever chemical trick. A protein(蛋白質(zhì)) at the tip of the root hairs called RHD2 helps them to take calcium(鈣) from the soil. Calcium makes the hairs grow, and produce more RHD2, and take more calcium.
But when an obstacle blocks the hair’s path, or the hair reaches the surface of the soil, the cycle is broken and growth starts in another direction.
This system gives plants the flexibility to explore a complex environment and to live in even the most unpromising soils, says Dolan.
In poor soils such as in parts of Australia and Africa, native plants have adapted by producing enormous numbers of root hairs. A better understanding of this adaptation will allow scientists to develop hairy rooted crops that can grow in unfriendly environments.
According to Dolan, “Research in the John Inners Center is taking a breeding approach to increase hair length in wheat but it will be some time before new cultivars(栽培變種) are developed.”
小題1:The passage is mainly about _______.
A.why the roots of plants grow into the soil but not above it
B.how the roots of plants grow into the soil but not above it
C.the process of plants growth
D.a(chǎn) growth control system of plants
小題2:How does the circle work?
A.RHD2 takes calcium from the soil, which makes hairs grow, and produce RHD2 and take more calcium
B.Roots take RHD2 and calcium from the soil and produce RHD2
C.Roots make hairs grow, and produce RHD2, and take more calcium
D.RHD2 takes protein, which makes hairs grow, and produce RHD2, and take more calcium
小題3:We can infer from the last paragraph that ________.
A.hairy rooted crops can grow better in unfriendly environments
B.a(chǎn) new cultivar of wheat with long hair has been developed by scientists
C.a(chǎn) new cultivar of wheat with long hair is still on test
D.the roots of plants always know which way to grow

Sea turtles come in many different sizes, shapes and colors. The shell of each sea turtle species is different in length, color, shape and the arrangement of the scales(鱗片).
Sea turtles do not have teeth but use their jaws (下巴)to eat. Their sense of smell is excellent. Their eyesight underwater is good, but they have near-sighted eyes out of water. Their special bodies make them adapt to life at sea. However, sea turtles maintain(保持) close ties to land.
Female sea turtles have to go to the seaside to lay their eggs in the sand; therefore, all baby sea turtles begin their lives on land. Most research on sea turtles has been focused on female turtles nesting and the baby sea turtles in the nest, largely because they can be found most easily. After decades of studying sea turtles, much has been learned about. However, many mysteries(謎) still remain.
Researchers do not yet know how long baby turtles spend in the open sea, or exactly where they go. People believe they spend their earliest years floating in the sea, where they do little more than eat and grow. Once turtles reach dinner-plate size, they appear at feeding grounds in waters near the shore. They grow slowly and take between 15 and 50 years to grow old enough to bear baby sea turtles, depending on the species. There is no way to know the age of a sea turtle from its physical appearance. It is believed that some species can live for over 100 years.
小題1:Which of the following statements is NOT true about sea turtles?
A.They don’t use teeth to eat.
B.They have a good sense of smell.
C.Sea turtles are more adaptable to life at sea.
D.Different species have different shells.
小題2:The underlined phrase “near-sighted eyes” in the second paragraph means_____.
A.good eyesightB.bad eyes
C.excellent eyesD.poor eyesight
小題3:Which of the following questions is answered in the text?
A.Why do female turtles lay eggs on land?
B.Why can’t people tell how old a sea turtle is from its appearance?
C.Where do the baby turtles usually go?
D.Do sea turtles grow very fast?
小題4:What would be the best title for the text?
A.Mysteries About Sea Turtles
B.Baby and Female Sea Turtles
C.The Growth of Different Sea Turtles
D.The Characteristics(特點(diǎn)) of Sea Turtles

At 2 p.m. on December 5, 1945, five Navy aircraft took off in perfect flying weather from a naval air installation in southeastern Florida, on a routine training mission over the Atlantic Ocean. Less than two hours later, the flight commander radioed that he was “completely lost”. Then there was silence. A rescue plane was sent to search for the missing aircraft, and it, too, disappeared. Despite one of history’s most extensive search efforts, involving more than 300 planes and dozens of ships, the Navy found nothing, not even an oil stain floating on the water.
This is just one of the many frightening stories told of “the Bermuda Triangle”, a mysterious area of the Atlantic Ocean roughly stretching southwest from Bermuda to the Florida coast and down to Puerto Rico. During the past 30 years, the triangle has claimed the lives of some 1,000 sailors and pilots.
Stranger yet are the numerous “ghost” ships that have been found floating crewless within the triangle. On one strange occasion in 1881, the cargo ship Ellen Austin discovered a small sailing ship, sails waving uselessly in the wind. The boat was full of wood with no one on deck. The captain of the Ellen Austin installed a new crew to sail it, but two days later, during a rough storm, the two ships temporarily lost sight of each other. When the captain again boarded the boat, he found his crew had disappeared. After a second crew was assigned, the ship was again lost in a fog bank. This time, no trace of the boat — or the crew — was ever found.
Charles Berlitz, a man with an interest in Atlantis, the legendary lost island, puts forward his theory that a giant solar crystal, which once was the power generator for Atlantis, lies on the ocean floor. From time to time, according to his theory, passing ships and planes set off the crystal, which confuses their instruments and engulfs them into the ocean.
Officially, the U.S. Navy does not recognize the triangle as a danger zone and is convinced that “the majority of disappearances in the triangle can be due to the unique features of the area’s environment.” These include the swift Gulf Stream current and the unexplored valleys under water of the Atlantic. Also, the triangle is one of only two places on earth where a compass needle points to true north rather than magnetic north, causing problems in navigation.
However, other scientists argue that beings from outer space have established a highly advanced civilization in the unexplored depths of the Atlantic inside the triangle. There, they believe, most of the missing vessels – and their crews – may still be on display for study by these higher intelligences.
小題1:The author develops the first two paragraphs through _______.
A.a(chǎn) series of events described in order of time

小題2:What did the captain of Ellen Austin do when he discovered a small sailing ship floating crewless?
A.He had all the wood transferred onto his own ship.
B.He had new powerful sails fixed on the small boat.
C.He sent a message that they were in danger and needed help.
D.He asked some of his sailors to get onto the boat to sail it.

For those who are tired doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app(application).
Strange though it may seem — “my wife already does that” was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week — Samsung is just one of many appliance makers racing to install (安裝) a large number of internet-connected features in machines in an effort to make them “smart”.
Last year, it was a refrigerator that tweeted. This year, it’s Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad.
The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owners is at work or on the bus.
Samsung says it’s not just something new — the app connection actually has some practical uses.
“If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when come home, so your clothes are refreshed and ready to go,” said spokesperson Amy Schmidt.
The company also says that with electricity rate(電價(jià))varying depending on the time of day, more control over when the machines are used can help save money.
Perhaps, but what they will probably really accomplish is what all good technologies do —enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV.
小題1:What can be inferred from the common response of the attendees at the CES?
A.The machine will be a big success.
B.their wives like doing the laundry.
C.The machine is unrelated to their life.
D.This kind of technology is familiar to them.
小題2:What can we learn about the new laundry machines?
A.They can tell you when your clothes need washing
B.They can be controlled with a smartphone
C.They are difficult to operate
D.They are sold at a low price
小題3:We can conclude form Samsung’s statements that ___________.
A.the app connection makes life easier
B.it is better to dry clothes in the morning
C.smartphone can shorten the drying time
D.we should refresh clothes back at home
小題4:What is the main idea of the last paragraph?
A.The laundry should be frequently checked
B.Lazy people like using such machines
C.Good technologies also cause problems
D.Television may help do the laundry.

Surprisingly, no one knows how many children receive education in English hospitals, still less the content or quality of that education. Proper records are just not kept. We know that more than 850,000 children go through hospital each year, and that every child of school age has a legal right to continue to receive education while in hospital. We also know there is only one hospital teacher to every 1,000 children in hospital.
Little wonder the latest survey concludes that the extent and type of hospital teaching available differ a great deal across the country. It is found that half the hospitals in England which admit children have no teacher. A further quarter have only a part-time teacher. The special children’s hospitals in major cities do best; general hospitals in the country and holiday areas are worst off. From this survey, one can estimate that fewer than one in five children have some contact with a hospital teacher—and that contact may be as little as two hours a day. Most children interviewed were surprised to find a teacher in hospital at all. They had not been prepared for it by parents or their own school. If there was a teacher they were much more likely to read books and do math or number work; without a teacher they would only play games.
Reasons for hospital teaching range from preventing a child falling behind and maintaining the habit of school to keeping a child occupied, and the latter is often all the teacher can do. The position and influence of many teachers was summed up when parents referred to them as “the library lady” or just “the helper”. Children tend to rely on concerned school friends to keep in touch with school work. Several parents spoke of requests for work being ignored or refused by the school. Once back at school children rarely get extra teaching, and are told to catch up as best they can.
Many short-stay child-patients catch up quickly. But schools do very little to ease the anxiety about falling behind expressed by many of the children interviewed.
小題1:Which of the following statements is true?
A.Every child in hospital receives some teaching.
B.Not enough is known about hospital teaching.
C.Hospital teaching is of poor quality.
D.The special children's hospitals are worst off.
小題2:It can be inferred from the latest survey that________.
A.hospital teaching across the country is similar
B.each hospital has at least one part-time teacher
C.a(chǎn)ll hospitals surveyed offer education to children
D.only one-fourth of the hospital have full-time teacher
小題3:The hospital teachers are found________.
A.not welcomed by the children and their parentsB.unnecessary
C.not quite helpfulD.capable
小題4:In order to catch up with their school work, children in hospital usually turn to________.
A.hospital teachersB.schoolmatesC.parents D.school teachers
小題5:We can conclude from the passage that the author is________.
A.unfavorable towards children receiving education in hospitals
B.in favor of the present state of teaching in hospitals
C.unsatisfied with the present state of hospital teaching
D.satisfied with the results of the latest survey

Every heard the old saying, “An apple a day keeps the doctor away”? It is true! Apples have a lot of nutritional value!
A medium sized apple has only 80 calories (卡). What a great snack choice! Not only is an apple low in calories, they contain absolutely no fat. Thus, eating apples as snacks, as opposed to chips or cakes, will help reduce the risk of cancer.
On top of reducing the risk of cancer, the low sodium (鈉) amounts in apples also help reduce high blood pressure and heart disease. They are cholesterol (膽固醇) free. They are also rich in vitamin A, which helps strengthen vision (視力) along with bone and tooth development.
Now that we know the nutritional facts, let’s take a look at some of the fun facts—That’s right! Apples can be fun, as well as healthy!
If an apple is fresh, it will float on water. Twenty-five percent of an apple is air, thus allowing it to float. Can you imagine bobbing (上下浮動(dòng)) for apples that sink?
And, did you know that an apple is covered with a natural layer of wax (蠟)? That’s what the peeling (剝下的皮) is. It protects the apple’s high water content, keeping the apple fresh.
Apples are a very important part of a healthy diet, but keep in mind they can be fun. And always remember, if an apple sinks in water, pick another one to bob for!
小題1:How many kinds of facts about apples are mentioned in the passage?
A.Two. B.Three.C.Four. D.Five.
小題2:Apples contain no _________.
A.calories and sodiumB.fat and sodium
C.fat and cholesterolD.cholesterol and sodium
小題3:We learn that an apple is probably _________ if it sinks in water.
A.too high in water contentB.still green
C.sweet and rich in vitaminsD.unsuitable to eat
小題4:Why do apples stay fresh for a long time?
A.Because they contain much water.
B.Because they have peeling with a layer of wax.
C.Because they contain much air.
D.Because they have peeling with nutritional value.
