In only two decades Asian Americans have become the fastest-growing U. S. minority (少数民族 ). As their children began moving up through the nation's schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation's best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact that Asian--American students who began their educations abroad arrived in the U. S. , with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.
Most Asian-American students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. Ah effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that breeds success, such as ideals that stress family values and emphasize education.
Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial (种族的) image. Many can remember when Chinese, Japanese and Filipino immigrants (移民) were the victims of social isolation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.
While making tremendous achievements at college, Asian-American students ______.
A.feel they are mistreated because of limited knowledge of English
B.are afraid that their academic successes bear a strong Asian character
C.still worry about unfair treatment in society
D.generally feel it a shame to have to depend on their parents

While Microsoft, which stole a move out of the Apple playbook, won cheers from high-end, creative-class consumers like business analysts, media designers and music producers. Microsoft launched several new products, but the big one was the Surface Studio--a 28-inch, extremely-high-resolution(分辨率) touchscreen tablet that doubles as a desktop PC screen. There’s also the Surface Dial, which can be placed on the Studio’s screen and revolved(旋转) to select menu items.
As Hayley Tsukayama remarked at The Washington Post, the Studio is really just a super-sized version of the Surface Books product that Microsoft has been selling for years. But if you’ve ever watched science fiction movies like Minority Report--where Tom Cruise seems to operate pictures and data hanging in mid-air by touching them, spreading their fingers to increase on details, and seeding files and information sliding from one folder(文件夹) to another with a click of the fingers, you can see how Microsoft is trying to show the same experience.
Meanwhile, Apple’s new products were almost like some fine promotions for its Apple TV. They boast(自夸) that the new MacBook Pros has a smaller size and more functions, and a new touchscreen bar on laptop keyboards where function keys used to be.
So what’s going on? In many ways, Apple is focusing on attracting the average consumers who have been attracted by Microsoft. And Microsoft is focusing on targeting the high-end professionals Apple has historically been associated with. You can even see this in the companies’ ad campaigns: Microsoft’s ads stress imagination and creativity, while Apple’s commercial chief designer Jony Ive, in calm and professional British accent, explained Apple has improved the performance and convenience of its MacBooks.
So Apple is trying to control the world of devices and laptops from the top down, starting with the high-end market and moving on to appeal to a broader base of consumers. Microsoft, having already strengthened itself within the bigger low-end market, is now attempting the opposite with a bottom-up strategy. Will these succeed? Time will tell…
What can we learn from the first paragraph?
A.Microsoft’s new products made a big hit
B.Apple’s products aim at high-end consumers
C.Apple and Microsoft developed the same products
D.The design of Microsoft’s products is original and unique
Why does the author mention the science fiction movie in Paragraph 3?A.To tell us Microsoft’s new products can be used in movies
B.To show how trendy Microsoft’s new products are
C.To show Microsoft’s new products are inspired by the movie
D.To advocate more people to see the science fiction movie
What is Paragraph 4 mainly about? A.The features of Apple’s new products
B.The bright future of Apple’s new products
C.The reason why Apple designed the new products
D.The difference between Apple’s new products and Apple TV
What can we learn about the two companies in promotion?A.They push forward high tech development
B.They lead the development of IT industry
C.They adopt different business strategies
D.They astonish the world from time to time
Student participation (参与)in tike classroom is not only accepted but also expected of the student in many courses. Some professors base part of the final grade on the student’ s oral participation. Although there are formal lectures during which the student has a passive role(i. e. , listening and taking notes) , many courses are organized around classroom discussions, student questions, and informal lectures. In graduate discussions the profess or has a “manager”role and the students make presentations and lead discussions. The students do the actual teaching in these discussions.
A professor’ s teaching method is another factor (因素)that determines the degree and type of student participation. Some professors prefer to control discussion while others prefer to guide the class without controlling it. Many professors encourage students to question their ideas. Students who object to the professor’ s point of view should be prepared to prove their positions.
In the teaching of science and mathematics, the controlling mode of instruction is generally traditional, with teachers presenting formal lectures and students taking notes. However,new educational trends have turned up in the humanities and social sciences in the past twenty years. Students in education,society, and history classes, for example, are often required to solve problems in groups, design projects, make presentations, and examine case studies. Since some college or university courses are“practical” rather than theoretical,they pay more attention to “doing” for themselves.
“Participation in the classroom is not only accepted but also expected of the student” in many courses except in____.
A.science and mathematics
B.the humanities and social sciences
C.informal lecture courses
D.discussion courses
From the passage we know that education in the humanities and society____.A.has not changed much
B.pay attention to students’ studying instead of teachers’ teaching
C.is much more important than that of science and mathematics
D.has become more practical than theoretical
The reason why some professors ask students to make presentations and lead discussions is that____.
A.these professors are often not well prepared before class
B.these professors want to stress “doing”
C.these professors want to test the students’ abilities
D.these professors are not willing to teach theory
Which of the following sentences is true according to the passage?A.Student participation is not common in the classroom in many courses like society.
B.Some professors want to control the classroom discussion.
C.Some professors usually want the students to take part in the teaching of science and mathematics.
D.New educational trends have turned up in teaching of natural sciences such as chemistry.

One summer evening I was sitting by the open window, reading a good science storybook. (79)I was so interested in the story I was reading that I did not notice that it was getting dark. When I realized it was too dark for me to read easily, I put the book down and got up to turn on the light. Just then I heard someone crying, "Help! Help!" it seemed to come from the trees at the other end of the yard. (80)I looked out but it was now too dark to see anything clearly. Almost immediately I heard the cry again. It sounded like a child, but I could not imagine what anybody could be doing in our backyard, unless one of the neighborhood children had climbed a tree and had not been able to get down.
I decided that I should go out and have a look in the yard, just in case someone was in trouble. I turned on the light and found for myself a flashlight and a baseball bat in the room. I thought they might be useful. Armed with these, I went out into the yard. Once again I heard the cry and this time there was no doubt that it came from the trees at the far end of the yard. "Who's there?" I called out as I walked across the yard towards the trees. But there was no answer. With the help of my flashlight, I searched all over that end of the yard, including the branches of the tree. There was no sign of anybody or anything. I came to the conclusion that my imagination was playing tricks on me, probably because of the story I was reading about strange creatures on another planet.
Feeling rather foolish about hunting around in my own backyard with a baseball bat, I went back into the house and put the bat and the flashlight away. I had just sat down to read my book again when I was frightened by the cry of "Help! Help!" from right behind me. I dropped my book and jumped up. There, sitting on the table was a large green and red bird. It was my neighbor's parrot(鹦鹉)!While I was out in the yard, the parrot must have seen the light in the living room and come in through the open window.
One summer evening the author was reading by the open window because ______.
A.it was getting dark.
B.it was too dark for him to read easily outside.
C.he didn't mm on the light.
D.none of the above
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.
According to the passage, it is difficult to be certain about the distant future of the universe because we______.
A.have too many conflicting theories
B.do not have enough funding to continue our research
C.are not sure how the universe is put together
D.have focused our investigations on the moon and planets
For many years, doctors have been studying the way the brain works. We all know that the brain has two sides, the left and the right. The right side controls the senses (seeing, hearing, feeling, tasting and smelling), and is the creative and imaginative side. The left side of the brain controls our logical thinking. It processes the information which comes in, and puts it into order, We call the left side the "educated" side of the brain and generally, in western societies, people have developed this side of the brain more than the fight side.
Scientists believe that our brain will work much more efficiently if both the right side and the left side are developed equally. In many schools today, teachers try to educate the children in such a way that both sides of the brain are used. This can be done with logical subjects including mathematics and science as well as with creative subjects such as art and literature. The result achieved by students who are educated in this way is usually better than the result of students who are educated in a more traditional way. Traditional teaching tends to exercise the left side of the brain without paying very much attention to the development of the right side.
great thinkers such as Bertand Russell the Philosopher, and Albert Einstein, the scientist, only in their work, but also in creative and imaginative activities. It was because of their many different interests in life that they were able to achieve the full development of both sides of their brain.
As long as Einstein and Russell lived, their brains functioned efficiently. It was their bodies, finally, which could not go on any longer.
The body improves ______.
A.with age
B.with use
C.with memory
D.with development
Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we can not. There is no ambiguity if we can see the setting of a switch: we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.
According to the passage, it is difficult to be certain about the distant future of the universe because we ______.
A.have too many conflicting theories
B.do not have enough funding to continue our research
C.are not sure how the universe is put together
D.have focused on investigations of the moon and planets
