[EX Q]: Article: Many of us feel uneasy when someone stands too close to us, talks to us too loudly or makes eye contact with us for too long. But have you ever wondered why those things make you uncomfortable? It's all about personal peace, which means not only an imaginary space around the body, but also the space around all the senses. People feel that their space is being violated when they meet with an unwelcome sound, smell or look. This is probably why a man on a crowded bus shouting into his mobile phone or a woman next to you putting on strong perfume makes you feel angry. Whether people have had a stronger wish to protect their personal space in recent times is hard to say. Yet studies of airlines show that people have a strong desire to have space to themselves. In a survey by Trip Advisor, a travel website, people said that if they had to pay more for some extra service, they would rather have larger seats than extra food. Although people may need their personal space, some hardly realize it. For example, people on a bus who hold newspapers in front of their faces to read in fact keep a distance from strangers. Go and watch a library table. You will notice that one of the corner seats will usually be taken first, because they are the farthest way. What if someone sits opposite to you? Maybe you will pile up books as if to make a wall. Preference for personal space are different from culture to culture. Scientists have found that Americans generally prefer more personal space than people from other cultures. In Latin cultures, however, people are more comfortable standing close to each other.
Question: The writer mainly _ in this article.
Options: (A) tells us how to achieve personal space (B) explains what personal space people need is (C) introduces some knowledge about personal space (D) argues for the importance of keeping personal space
Asnwer: C
[EX A]: Yes

[EX Q]: Article: Today in schools, it's not unusual for students to sit in the same kind of desks in the same kind of classrooms as their parents did. Schools have made progress by making use of computers and PDAs in the classroom, yet one design company believes that changes are needed, so they describe what a future classroom may look like. "Kids are being taught to sit at these wooden desks that are basically designed for writing," said Mark Dziersk, the senior vice president of the design. "They're being lectured in a structured environment." The solution is a "customizable education system" called Gooru that reorganizes the classroom and replaces books, desks, pens, and so on. The three-part technology system consists of an interactive PDA called the GooBall, a backpack and a removable LCD screen for each student. Students can sit, stand or lie down when using the devices, and are not limited to desks. The idea was presented at last month's South by Southwest Interactive Conference. While some educators think the idea is interesting, they doubt whether schools will pay for the expensive and complicated system. The GooBall is an interactive communication device with six layers of learning software. The device monitors a student's heart rate and body temperature and uses GPS to track where they are. It includes instant messaging, a compass, a watch, and a topic-specific alert system that directs a student to related articles and books about whatever they are studying. Students can also choose an animal icon to show their personality. The backpack houses the main power supply for the system and holds some personal items. The pocket keeps items locked tight with a fingerprint security zipper. The portable screen functions like a laptop, providing wireless Internet access and streaming video. It also has a touch screen interface. "I think it's an excellent idea," said Gary Tankard, a sixth-grader who has seen the prototype . "I'm sure that 90 percent of kids would really like to have it."
Question: The education system called Gooru is made up of _ .
Options: (A) an LCD screen and a backpack (B) a PDA, a GooBall and a backpack (C) a PDA and an LCD screen (D) a GooBall, a backpack and an LCD screen

[EX Q]: Article: Bicycles are a great way to get around. They're fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike-- make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects. This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured(had)three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about. Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to _ some of his country's economic troubles. "I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights." Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped (fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets. The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine. "You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.
Question: Which of the following is true according to the passage?
Options: (A) ISEF is an exhibiton displaying bicycle experiments designed by students. (B) Looking closely at things you are concerned about can lead to scientific research. (C) Renato's improvement of the bicycle has solved the country's great problem. (D) Renato's special bicycle will soon be put into use in remote areas.'
Asnwer: B
