[EX Q]: Article: Testing has taken the place of teaching in most public schools. Pretests, drills, tests, and retests. They know that the best way to read a textbook is to look at the questions at the end of the chapter and then read the text quickly for the answers. I believe that my daughter Erica, who gets excellent marks, has never read a chapter of any of her school textbooks all the way through. And teachers are often heard to say proudly and openly that they teach to the test. Teaching to the test is a curious phenomenon . Instead of deciding what skills students ought to learn, helping students learn them, and then using some methods of assessment to discover whether students have mastered the skills, teachers are encouraged to teach the students in the opposite way. First one looks at a test. Then one chooses the skills needed not to master reading, but to do well in the test. Finally, the test skills are taught. The ability to read or write might suggest the ability to do reasonably well on standardized tests. However, neither reading nor writing develops simply through being taught to take tests. We must be careful to avoid mistaking preparations for a test of a skill with the acquisition of that skill. Too many discussions of basic skills make this misunderstanding because people are tested rather than concerned with the nature and quality of what is taught. Recently, many schools have faced what could be called the crisis of comprehension or, in simple words, the phenomenon of students with grammar skills still being unable to understand what they read. These students are quite good at test taking and filling in workbooks. However, they have little or no experience reading or thinking, and talking about what they read. They know the details but can't see or understand the whole. They are taught to be so concerned with grades that they have no time to think about meaning, and reread things if necessary.

Options: (A) her cleverness in test taking (B) the good way to take tests (C) the improper way of teaching (D) the best way to read textbooks
[EX A]: C

[EX Q]: Article: There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. and some do one simple job. When an automatic washing machine is switched on, water pours in. The machine waits until the water is warm enough for washing clothes. It does this by "feedback" . Information about what is happening is feedback into the robot to tell what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us. So robots are like human beings in two ways. They work and they have feedback. In some ways robots are better than human beings. They work quickly and do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. First their electronic brain must be shown how the job is done. A person moves the robot's "arms" and "hands" through each part of the job. The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes and sizes of the objects. These robots have computer brains linked to their eyes and fingers, which control their actions. The expensive robots are used in scientific research. They do such job as handling radioactive materials.
Question: In this passage the author tells us that _ .
Options: (A) robots are very popular (B) there are various kinds of robots (C) we see robots only at certain times (D) robots can be easily controlled
[EX A]: A

[EX Q]: Article: Can you imagine that several hundred years ago, tomatoes were seen as _ food in Europe? What made Europeans believe this was John Gerard's publication of Herbal in 1597. Gerard wrote: "The leaves and stalks of the tomato plant are toxic." Undoubtedly, Gerard's opinion was based on a misunderstanding of tomatoes. But his opinion was widely spread in Britain and North America for over two hundred years. In the late 1700s, a lot of Europeans held more fears for tomatoes. A nick name for the fruit was "poison apple" because it was believed that aristocrats got sick and died after eating them. But the actual reason was the pewter plates they used. Since tomatoes are high in acidity, when placed on the plates, the lead in the plates would dissolve . This caused many deaths. Unluckily, no one knew this at that time. So the innocent tomatoes were picked as the killer. Today, more than one and a half billion tons of tomatoes are produced every year around the world. Tomatoes are cooked in various ways. This healthy and tasty food finally wins its innocence back.
Question: Which of the following can be the best title for this passage?
Options: (A) Europeans' fears for tomatoes (B) History of tomato planting (C) Why do people eat so many tomatoes (D) How did the tomato prove its value
[EX A]:
A
