Q: Read the following article and answer the question. Article: Years ago, as we know, zoos kept animals in cages. Cages made it easy for visitors to see the animals, but a small cage is not a good place for an animal to live in. Today animals live in open areas. There are usually plants and a little lake around, like the animals' habitats. Visitors usually stay in the bus to see the animals outside. Zoos help to protect all kinds of animals. They protect animals in the zoo as well as animals in the wild. How do they do this? Zoos tell people how animals live in the wild and how to help protect their environment. The number of many kinds of plants and animals is becoming smaller and smaller. Mammoths, which are related with Asia elephants, are now extinct(.Scientists say that 74 different kinds of living things are disappearing a day! Zoos are working together to help animals-our friends. Question: Today, zoos keep animals _ . Answer:

Read the following article and answer the question. Article: "BANG!" the door caused a reverberation . It was just standing there, with Father standing on one side, and I on the other side. We were both in great anger. "Never set foot in this house again!" stormed Father. With tears welling up in my eyes, I rushed out of the flat and ran along the street. The street lights were shining, causing rather sad-feeling. I wandered aimlessly. A young father who held a child in his arms walked past me. I felt as if I saw my childhood from another space: happy and carefree. But now... I don't know whether it is because I have grown up or because Dad is getting old. We differ in our ways of thinking. He always puts his opinions and codes of behaviour on me. Whenever I do something wrong, he never admits it. We are just like two people coming from two different worlds. It feels like there is an iron door between us that can never be opened. I wandered in the streets, without a destination in mind. My heart was frozen on this hot summer night. As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company. When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on. I thought to myself: "Is Father waiting for me, or is he still angry with me?" In fact, it was nothing. Perhaps, Dad was throwing away some of his old stamps. Perhaps he thought they were useless. I never had the courage to tell him that I liked collecting stamps. I can't stand his outrageous words: "I can't throw you away, let alone these old papers?" All the lights were off except Father's. Dad was always like this. Maybe he didn't know how to express himself. After shouting at me, he never showed any mercy or any moments of regret. After an argument he has the habit of creeping up in my sleep and then tucking me underneath the covers. This was how he always was. He has been a leader for so long that telling everyone else what to do has become his second nature. The light was still on. "Am I wrong?" I whispered,... Question: Why do you think the father often shouts at his son? Answer:
****
A: Perhaps the father has got used to doing that.

input with options: Read the following article and answer the question. Article: What would you do if a stranger gave you some medicine and it would keep you slim or help you do well in exams? Would you take it? Students at Shenzhen Luohu Foreign Language Middle School have learned to keep themselves safe by saying "no". In fact, what those strangers want to give them are drugs . Drugs are dangerous to your health! "Because teens don't know much about drugs, they might want to try them," said Zhang Dongsheng, the director of Shenzhen Drug Control Office. Now, many schools arrange courses or organize some activities to help students know about drugs. Liang, 16, was a good student before trying drugs. One day, some old friends told him it would be fun. After taking drugs only once, he found it very hard to stop. Liang began to spend all his time and money on drugs. Soon, he stopped going to school and started stealing. In the end, he was put in prison. In China, taking drugs is becoming a big problem for teens. According to a survey, about one million people in China were using illegal drugs last year, and 72% of them were young people. Worse still, there are about10,000 drug users under 16 now. Zhang has some good advice on staying clean. He said, "Drugs are dangerous. Never try them, even if you're curious! It is the most important for you to keep safe and healthy."
