问题 90: 21. 阅读下面的短文，根据文章内容进行选择。
There is no denying that students should learn something about how computers work.For people should have some basic idea of how the things that they use do what they do. Further, students might be helped by a course that considers the computer's impact on society.Computer literacy is not a form of literacy (读写能力); it is a trade skill.
Learning how to use a computer and learning how to program one are two distinct activities. The competent citizens of tomorrow should free themselves from their fear of computers. But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun, and while our society needs some people who are experts at it, the same is true of auto repair and violin-making.
Learning how to use a computer is not difficult, and it gets easier as programs become more “user-friendly”. Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen. What does the phrase “learning to use a computer” mean? It sounds like “learning to drive a car”, that is, it sounds as if there is some set of definite skills that, once acquired, enable one to use a computer.
In fact, “learning to use a computer” is much more like “learning to play a game”, but learning the rules of one game may not help you play a second game, whose rules may not be the same. There is no such a thing as teaching someone how to use a computer. One can only teach people to use this or that program and generally that is easily accomplished.
1. To be the competent citizens of tomorrow, people should understand that programming a computer is more essential than repairing a car.
2. In the second paragraph “auto repair” and “violin-making” are mentioned to show that people who can use a computer don't necessarily have to know computer programming.
3. Learning to use a computer is getting easier all the time because programs are becoming less complicated.
4. According to the author, the phrase “learning to use a computer” (Lines 3-4, Para.3) means learning specific programs.
5. The author's purpose in writing this passage is to explain the concept of computer literacy.

问题 91: 22. 阅读下面的短文，根据文章内容进行选择。
Can trees talk? Yes, but not in words. Scientists have reason to believe that trees do communicate (交际) with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars (毛虫) changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special smell—a signal (信号) causing its neighbors to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn't need to be in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar (花蜜) for honey. So why shouldn't trees have ways of sending message?
1. It can be concluded from the passage that caterpillars do not feed on leaves that .
A.are lying on the ground
B.have an unpleasant taste
C.bees don't like
2.The willow tree described in the passage protected itself by .
A.growing more branches
B.communicating with birds and bees
C.changing its leaf chemistry
3.According to the passage, the willow tree was able to communicate with other trees by .
A.waving its branches
B.giving off a special smell
C.dropping its leaves
4. According to this passage, bees communicate by .
A.making special movement
B.touching one another
C.smelling one another
5.The author believes that the incident described in the passage .
A.cannot be taken seriously
B.should no longer be permitted
C.seems completely reasonable

问题 92: 23. 阅读下面的短文，根据文章内容进行选择。
If you think 3D printing is only good for making flimsy paperweights, then you're pretty much right. However, a group of audacious Dutch architects have already begun 3D printing an entire canal house in Amsterdam. Is the first 3D printed house a gimmick? Definitely! Is it an experiment that pushes the possibilities for 3D printing technology and architecture? Maybe!
3D Print Canal House is the brainchild of DUS Architects. “KamerMaker”, Dutch for “room maker”, is their giant printer built inside a shipping container. Just a few weeks ago, KamerMaker began printing plastic furniture and walls at an empty canal-side lot in northern Amsterdam. Smaller versions of the unusual honeycomb walls have been tested on normal desktop printers, and everyone just needed to scale it up. Well, if only it were that easy.
“The printer did not always manage to spread the plastic evenly, making some of the ribs of the honeycomb structure of the block uneven,” reported ARN (Australian Radio Network), to the surprise of no one who has used a 3D printer. But the architects remain optimistic. The first few printed blocks are meant to be test pieces as they improve the process.
It takes about a week to print a 3-meter high block right now. The project's leader hopes to eventually get that down to two hours and finish the first of 12 rooms in a year, and the entire house in less than 3 years.
Ultimately, 3D Print Canal House is an architectural research project, one that is very much being conducted in the public eye: you can actually buy tickets to visit the construction site for 2.50 Euros.
The top floors will become more ornate, for example, as newer techniques are incorporated. They'll explore the possibilities of 3D printing, like the honeycomb walls or an entire room recycled, redesigned, and built anew. Nobody's going to move into a 3D printed house soon, but, if anyone ever does, something might be learned from this experiment by the canal.
1. What have the Dutch architects begun to use the 3D printer to do according to the passage?
A.To make heavy paperweights.
B.To print the unusual honeycomb.
C.To print an entire canal house.
2. Where did KamerMaker begin printing plastic furniture and walls several weeks ago?
A.It was inside a shipping container in Amsterdam.
B.It was at an empty canal-side lot in northern Amsterdam.
C.It was in a canal house in Amsterdam.
3. What is the weakness of the 3D printer mentioned in the passage?
A.It cannot always spread the plastic evenly.
B.It needs to be shortened.
C.It cannot make the ribs of the honeycomb structure.
4. How long will it take for the 3D printer to make the canal house in Amsterdam?
A.A week.
B.Two hours.
C.Less than 3 years.
5. Which of the following statements is WRONG according to the passage?
A.This canal house is being built in the public eye.
B.The top floors of the canal house will be more decorated.
C.Someone is going to move into this canal house soon.
