I'm taking a test and have to guess the right answer to the question after the article. Article: Japan is an island country in the Pacific Ocean. As the Japanese students already know, four main islands and more than 3,000 small ones stretch from north to south for about 1,300 miles. As for the climate of the country, well, it's hot and humid in summer, but it is quite cold and wet in Japan during winter. Typhoons, which are violent tropical storms, often threaten Japan during the fall. That's, of course, during the harvest season. The population of Japan is about 110,5 million. It may seem hard to believe, but the average population density of the country is about 678 persons per square mile. About two thirds of the entire population lives in Japan's cities. The other one third lives in the suburbs or in the countryside. No other country in southern or eastern Asia has such a large urban, or city population. Tokyo, the capital city of Japan, is the most density-populated city in the world. At last count there were more than 11.5 million people living in Tokyo. Question: Most of the people in Japan live _ . Options: A: in the rural areas B: in the countryside C: around the cities D: in the cities
(Answer)

I'm taking a test and have to guess the right answer to the question after the article. Article: Plastic is everywhere because plastic is an extremely useful material. It is cheap, strong and lightweight. What's more, it can take on nearly any form or shape, from soft and stretchy to hard and glasslike. Plastic, however, is far from perfect. It may even be bad for us. Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder . Two types of chemicals in particular have raised special concern lately. They are called phthalates and Bisphenol-A , BPA for short. Not all plastic products contain them. But the ones that do are surrounded by controversy . That's because experts disagree on how dangerous these chemicals are. Plastic is a single word, but plastic isn't just one thing. What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture. Plasticizers are added to plastic during the manufacturing process. Phthalates and BPA are two types of plasticizers that work in different ways. Phthalates add softness to things like shampoo bottles, raincoats and rubber. They are also used in perfumes and makeup. BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles. BPA also appears in food and soda cans, DVDs and other unexpected places. How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep out of the plastic. Even though we can't see them, we eat them, drink them and breathe them in. Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic. Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three. California and Washington have done the same. And a number of other states are... Question: What is the passage mainly about? Options: A: A new ban on plastic products. B: Problems caused by the plastic. C: Good points of the plastic. D: The use of plasticizers.

I'm taking a test and have to guess the right answer to the question after the article. Article: Idioms are phrases and sentences that do not mean exactly what they say. Even if you know the meaning of each word you see or hear, you may not understand the idiom because you don't understand the culture behind it. For example, if an American boy asks his mother what's for dinner tomorrow, she may say "I'll play it by ear", that means she doesn't have plans for dinner and she will decide later. "Play by ear" used to mean playing music using the sheet music, but now people often use it when they're not talking about music. There're many idioms in English. If you learn to use them, your English will be more vivid and colorful. English idioms are more common in spoken English. They can be difficult to remember sometimes. Next time when you hear somebody saying to you, "Give me a hand", you don't necessarily stretch out your hand to him/her, but you do need to be helpful. And when the situation is out of hand, you usually can do very little to manage all that. What about a green hand? It's not about the color of your hand! You're a green hand when you are very new at your work and don't have much experience. If you and your partner always work together hand in glove, you two definitely work together very well. Can you guess the meanings of some common English idioms to do with parts of your body? Question: If a mother says "I'll play it by ear" to talk about the dinner, she means _ . Options: A: she will cook dinner while listening to music at the same time B: she doesn't hear what others are talking about. C: she will play music using the sheet music instead of cooking dinner D: She doesn't have plans for dinner and will decide later
