[Q]: Article: Roughly speaking, teachers in traditional education may feel that students are too young to know much about the world, and have to be told what to do most of the time. By contrast, open education offers teachers quite different feelings. Students are expected to be responsible for their own education--to discover subjects by themselves instead of being made to study them. This way of teaching allows the students to grow independently and to develop their own interests in many subjects. Some students who do badly in a traditional classroom will be happier in an open classroom and enjoy learning. They will not have to worry about grades or rules at all. However, many students won't do well in an open classroom. For these students, they will do little in school if there are too few rules. They will not make good use of open education, which is so different from traditional class, because they may have a problem getting used to making so many choices on their own. For them it is important to have some rules to direct them. They may worry about the rules even when there are no rules. In addition to that, some traditional teachers do not believe in open education and do not like it either. Since both of some good points and bad points of the open education have been explained clearly, you may have your own opinion on the issue. Personally, I think that the concept of open education is good only in theory. In actual fact, it may not work very well in a real class or school. I believe, most students, but of course not all students, need some structure in their classes. They may want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.
Question: Open education allows the students to _ .
Options: (A) grow as the educated (B) be responsible for their life (C) discover subjects outside class (D) develop their own interests
[A]: D

[Q]: Article: Handshaking, though a European practise is often seen in big cities of China. Nobody knows exactly when the practice started in Europe. It is said that long long ago in Europe when people met, they showed their unarmed hands to each other as a sign of goodwill. As time went on and trade in cities grew rapidly, people in cities began to clap each other's hands to make a deal or to reach an agreement. This practice was later changed into shaking hands among friends on meeting or leaving each other. "Let's shake (hands) on it" sometimes means agreement reached. Do the Europeans shake hands wherever they go and with whomever they meet? No. Sometimes the Chinese abroad reach out their hands too often to be polite. It is really very impolite to give your hand when the other party, especially when it is a woman, shows little interest in shaking hands with you and when the meeting does not mean anything to him or-her. Even if, for politeness, he holds out his unwilling hand in answer to your uninvited hand, just touch it slightly- There is generally a misunderstanding among the Chinese that westerners are usually open and straighforward, while the Chinese are rather reserved in manner. But in fact some people in western countries more reserved than some Chinese today. So it is a good idea to shake hands with a westerner only when he shows interest in further relations with you.
Question: In the old days in Europe, people put out their unarmed hands to each other _ .
Options: (A) to make a deal (B) to greet each other (C) to show friendliness (D) to reach an agreement

[Q]: Article: If you live in the U.S., you're probably used to throwing banana peel into the trash. But people in other countries, including India, have been taking advantages of their nutritional benefits for many years. While the flesh of a banana is soft and sweet, the skin is thick, hard and slightly bitter. To eat the peel, you can fry, bake, or boil it for at least 10 minutes. Also, the riper bananas get, the thinner and sweeter banana peel will become. That's because of a natural plant hormone called ethylene that fruits release as they ripen. Ethylene interacts with the sugars and fiber in the banana skin, changing complex sugars into simple sugars and breaking down pectin, a form of fiber in bananas that keeps them stiff. That's why the older your banana is, the flimsier it feels. The sweet flesh of a medium-sized banana contains great percentages of your daily recommended intake of various nutrients, such as: *12% of your daily fiber, which helps with digestion and may help lower your risk of diabetes *17% of your vitamin C, which is important for your immune system as well as your growth *20% of your vitamin B6, which aids the body's ability to turn food into energy *12% of your potassium, which helps with the development of cells, tissues, and organs throughout the body If you eat the skin along with the flesh, you will get an even bigger increase in these same nutrients. Eating the peel is not only good for your body but also better for the earth. The average American ate 11.4 pounds of bananas in 2014. Since a medium-sized banana weighs about 0.3 pounds, that equates to about 38 bananas per person, or about 12 billion for the whole of the U.S. And since most of us throw away the peel, that also means a lot of organic waste.
Question: We can learn from the text that in the U.S. people _ .
Options: (A) like eating bananas (B) waste a lot of food every year (C) don't make good use of banana peel (D) know little about the value of the flesh of bananas
