I'm taking a test and have to guess the right answer to the question after the article. Article: What is the hottest topic at your school recently? In Taiyuan No.55 Middle School, it's money. The school held an activity called "making money" last weekend. About 200 Junior 1 and Junior 2 students were divided into 30 teams. They went out to make money by selling things. What did they choose to sell? Some sold newspapers; some chose bottled water; some sold environmentally friendly shopping bags and bamboo baskets. Hu Qing's team decided to sell some useful books in front of the Children Activity Center. They thought parents would like to buy the books for their children. But unfortunately, they met urban management officers . The officers asked them to leave. "We played hide-and-seek with the officers for the whole morning" said Hu. "Finally we had to give up." Wang Bing and her team sold ice cream in a square. They didn't meet any officers. But few people were interested in what they were selling. The team then put up a board saying "For Country Kids". It worked. More people came to their stall . A foreigner even gave them 100 yuan. "He didn't want any change. He said he wanted to help the children," said Wang. "We were touched." Later that day they gave the 100 yuan and more to the "Project Hope" office. Meng Zhaoxiang and his team were luckier. They sold all their cakes in four hours, spending 39.5 yuan and getting back 80 yuan. They made 40.5 yuan. "It was not easy to make the money," said Meng. "Some people just looked. Others just tasted but didn't buy. Now I know how hard it is for our parents to make the money we need to lead happy lives." Question: _ took part in the activity. Options: A: About 200 of Junior 1 and Junior 2 students B: Some teachers C: About 200 students of the three grades D: About200 Junior 1 students

I'm taking a test and have to guess the right answer to the question after the article. Article: What is the definition of "happiness?" Is it material wealth filled with fancy cars, a dream house or jewelry? Or does happiness simply mean having a roof over your head? Food in the fridge? Having a swimming pool? A designer Gucci bag? Love? Money? A perfect job? Do you recall a time----let's say when you were about 5 years old-----what defined happiness back then? Was it getting a puppy for Christmas? Or maybe, you were a child of divorce; and all you wanted was for Mom and Dad to get back together again? Then as you got older, you were hoping that someone would ask you to the party that would have made your day. During college, good grades made you happy, but it was short-lived. Because in the real world, you had to look for a job, and competition was fierce. But then, you got a perfect job, could you be happy? We like having and accumulating things. We work so we can pay our rents, credit card debts, school loans, car payments... The list goes on and on. And at some point, we realize that apart from having most of what we want, we still aren't happy. Now since we've learned to adapt to new standards which we've created for ourselves, we find that we have less time, less patience, less sleep, which leads to more stress and more anxiety. Therefore, don't stupidly make a conclusion that happiness is just based on "things". Sometimes, we trade our lives for not only basic necessities, but for excessive items and services as well. Certainly, you've heard of individuals trying to "find themselves", or to "rediscover themselves". But the point has been missed: happiness is already there. Disappointments and tragedies in life will come and go, but happiness never leaves you. We can lose our jobs, but be grateful for those who love us. We can lose our homes to nature, but be thankful to be alive. If we think we are happy, we are indeed happy. Happiness is merely a perception of each individual. Happiness is part of love, and love is an ocean. Go dive in and get some, and then share it with everyone, which can be... Question: It can be inferred from Para.3 that _ . Options: A: accumulating things is not a good habit. B: pressure and worry should be ridded of. C: people have to work hard to pay for daily necessities D: some aren't satisfied with what they have possessed

I'm taking a test and have to guess the right answer to the question after the article. Article: Science, as we think, was born when the Greek philosopher ( ) Thales ( about 640-546 B.C.) asked a difficult question: What makes up our universe? No one had a ready answer, so Thales went on studying the earth around him, the sky and the stars. He saw so much water on earth and so much water falling from the sky as rain that he decided water must be the basic substance ( ) of the universe. Other Greek thinkers became interested in this question. They suggested other answers. One said that because air lies around the earth, it must be air that makes up all things. Another said that fire, appearing in different forms, was the building block of the universe. The Greek philosophers were feeling their way towards the ideas on which chemistry is based. Centuries later, scientists proved that the universe is made up of certain basic substances. But the list is much more _ than the Greeks realized. We now know of 103 basic substances which we call " elements ( )". Question: After reading the passage, we can be sure that _ . Options: A: nothing ever changes in the universe B: Thales decided that the basic substance of the universe was air C: the universe is made up of four different substances D: the early Greek thinkers did much valuable work for the progress of science
