Can you imagine a classroom without one thing that has long been considered a necessary part? No notebooks, no textbooks, no test papers. Nor are there any pencils or pens, which always seem to run out of ink at the critical moment.
A “Paperless classroom” is what more and more schools are trying to realize. Students don’t do any handwriting in this class. Instead, they use hand-sized or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer.
Having computers also means that students can use the Web. They can look up information on any subject they’re studying, from maths to social science.
A high school teacher, Judy Herrel in Florida, US, described how her class used the Web. “Using a book that’s three or four years old is impossible,” she said.
A paperless classroom is a big step towards reducing the waste of paper.
“Think about the money and trees we could save with the computers,” she said.
But, with all this technology, there’s always a risk that the machines will break down. So, in case of a power failure or a technical problem, paper textbooks should still be widely available (可得到的) for these students.
小題1:The underlined word “critical” in the first paragraph probably has the same meaning as _______.
A.worryingB.dangerousC.happyD.important
小題2:You are sure to find __________ in a paperless classroom.
A.pensB.computersC.test papersD.notebooks
小題3:According to Judy Herrel, __________.
A.the Web can talk the students everywhere
B.the Web can take the place of teachers
C.the Web is a better tool for information
D.the Web is for downloading information
小題4:The paper textbooks should still be widely available because __________.
A.students won’t have trouble with their pens
B.computers may break down sometimes
C.students may not get all information from the Internet
D.paper textbooks may give students more information

小題1:D
小題2:B
小題3:C
小題4:B

小題1:第一段最后一句為which always seem to run out of ink at the critical moment.所表示的含義為應(yīng)該為似乎總是在最關(guān)鍵的時(shí)候用完了墨水,所以critical單詞的意思最接近重要的意思,故本題選D。
小題2:本文第二段第二句為they use hand-sized or specially-designed computers.所表示的含義為在無紙的課堂需要電腦,故本題選B。
小題3:本文第三段第一句為Having computers also means that students can use the Web. They can look up information on any subject they’re studying,所表示的含義為所表示的含義為網(wǎng)頁為我們查找有關(guān)學(xué)習(xí)的信息提供了更好的工具,故本題選C。
小題4:本文最后一段提到電腦有時(shí)會(huì)被摔壞,所以紙課本應(yīng)該仍然被廣泛的使用,故本題選B。

Do you know that women’s brains are smaller than men’s? Normally the women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent(聰明的) than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain is made up of “grey matter” and “white matter”. While men have more of the white matter, the amount(數(shù)量)of “thinking” brain is almost the same in both men and women.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes(性別). As white matter is the key to spatial(空間的)tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for directions … and women often need to!
The differences begin when fetuses(胎兒)are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.
小題1:Which of the following is TRUE according to Paragraph 1?
A.Grey matter controls thinking in the brain.
B.Men’s brain is 10% less than women’s.
C.Grey matter plays the same role as white matter.
D.Men and women have the same amount of white matter.
小題2:What can you infer from Paragraphs 2 and 3?
A.Men have weaker spatial abilities.
B.Women do not need to tell directions.
C.Women prefer doing many things at a time.
D.Women do many jobs at a time better than men.
小題3:What can you learn from Paragraph 4?
A.Our children needed more spatial skills.
B.Women may have more feelings than men.
C.Young boys may be stronger than young girls.
D.More women take up jobs requiring speech skills.
小題4: The passage is mainly about _______.
A.ways of being more intelligent
B.differences between men and women
C.studies on brains between two sexes
D.studies on white matter and grey matter

Weather has a strong effect(影響) on people. It influences health, intelligence (智力) and feelings. In August, it is very hot and wet in the southern part of the United States. People there easily have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is hot at some times and very cold at other times. People in those states will have heart trouble after the weather changes in February or March.
The weather can also influence intelligence. For example, in a 1983 study by scientists, the IQ scores of some college students were very high during storm, but after the storm, their scores were low. Storms can increase intelligence. Very hot weather, on the other hand, can decrease(減少) it. Students in many schools of the United States often do badly in exams in the hot months of the year(July and August).
Weather also has a strong effect on people’s feeling. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel depressed during cold weather. In hot summer weather, on the other hand, fat people may feel unhappy. At about 65F, people become stronger.
Low air pressure(氣壓) makes people feel free, but it also increases forgetful- ness. People leave more bags and umbrellas on buses and in stores on low pressure days. There is a“perfect weather”for work and health. People feel best at a tempera- ture of about 64F with 65 percent humidity(濕度).
Are you feeling sick, sad, tired, forgetful, or very intelligent today? The weather may be the reason.
小題1:Intelligence may be lower______.
A.during a stormB.when it is sunny
C.on a very hot dayD.when you take in an exam
小題2: In the third paragraph,“depressed”means         .
A.興奮的B.愉快的C.憂郁的D.擔(dān)心的
小題3: In“perfect weather”,          .
A.both the fat and the thin are healthy
B.the students do very well in examinations
C.the air pressure is low
D.the humidity is 65 percent and the temperature is about 64F

How to Become Fit?
Healthy eating habit along with regular exercise is the only way to become fit. If you have the correct number of calories and exercise regularly, you will lose weight, keep fit, and feel great, too.
During your teenage years, it is important to give your body the energy it needs. If you skip (跳過) meals, you won’t get enough calories, and then you will feel tired.
