Read the following article and answer the question. Article: Health experts have long worried about the increasing rate of obesity in kids. It's an important concern: Being weight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the causes. But would you ever have imagined there might be a connection between the bacteria that lived in your guts when you were a baby and the chance that you would become overweight? Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts. You probably think of bacteria only as germs that can make you sick. While it's true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These "good" bacteria live in your guts, where they process the food you eat. Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby's body. Growing babies get additional "good" bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later. So how could these bacteria affect weight? The researchers still haven't tested that question, but future tests might lead to an answer. Question: The purpose of writing this passage is to _ . Answer:

OPTIONS:
- introduce the role of bacteria in children's weight
- analyze the influence of obesity on kids
- give advice on how to lose weight quickly
- explain the function of bacteria in foods

Answer: introduce the role of bacteria in children's weight

Read the following article and answer the question. Article: Recently more students are choosing to study abroad as they think it is worthwhile. However, some people think it is not a good idea. There are a number of disadvantages in studying abroad. The following paragraphs will explain why students have these views and the advantages of studying abroad will be discussed. Students studying abroad may suffer from racial discrimination . As they left their home country, they will become part of a minority group in the new country. The majority group may have a sense of superiority and try to bully them. It is common that Americans or the British discriminate against people from other countries since many of them think that white people are better than others. In addition, the students may lose their own cultures. Since they have moved to a new place, all the thing there - people, lifestyle and the living environment---would be different from those in their own country. As they will have close contact with the local people and culture, they will be influenced by the new culture even without realizing it. It is ironic that a Chinese person speaks better English than Chinese and forgets about Chinese culture after studying abroad for a few years. On the other hand, studying abroad will widen the view of students. Although they may give up their own culture, they can really learn from others. As students of the modern world , they should not limit their scope to their home country, but get exposed to the world. Studying abroad can help them expand their horizon and learn many things in the host country, as they will meet and make friends with people from all over the world. So, studying abroad is good for them. Furthermore, students will learn how to be mature and independent. Students, when in their home country, usually rely on their parents. Statistics show that Chinese students usually rely heavily on their parents; they will leave problems alone and ask their parents to solve them. If they are studying abroad, on many occasions they have to learn how to cope... Question: Students studying abroad _ . Answer:

OPTIONS:
- will be respected by the locals.
- will forget their ancestors.
- may be treated unfair.
- may have difficulty overcoming homesickness.

Answer: may be treated unfair.

Read the following article and answer the question. Article: Sir Nicholas Winton, rescuer of children, died on July 1st,2015,aged 106. When the letters and the honor came knocking on the door of his house in Maidenhead, and the filmmakers came calling, Nicholas Winton always protested that he was no hero. Heroes faced danger; he never had. They put their lives on the line; he had just worked at home in Hampstead, after a day being a stockbroker in the City. They avoided bullets and the secret police; he wrote letters, made telephone calls,and composed lists. The fact that he had rescued 669 children from Czechoslovakia just as the Nazis invaded did not, in his mind, constitute heroism. He hadn't gone out there in 1938 with any burning urge to do good; just for a holiday, in fact. Nor had he gone looking for children to rescue. Instead they and their parents had come to him, as soon as word got round that he might be able to help them leave Prague and get to the West. From 6.00 a.m. the knocks would come at the door of his room in the Europa Hotel, and he would open it to find some shivering, starving, desperate figure. When faced with a problem, his instinct was to solve it. So he made lists of the children, took their photographs, got them Home Office entry permits, found them foster families and organised their departure on trains, via the Netherlands, to Liverpool Street. After just three weeks in Prague, he went back to Britain and carried on the work from there. The British Committee for Refugees from Czechoslovakia gave him almost no help, so he took sole charge himself. The Home Office was slow with entry permits, so he copied some illegally. In search of foster-parents for the children he put their photos in Picture Post; in the hope of farther havens for them he wrote to governors and senators in America and even to President Roosevelt, to no avail. He could have rescued at least 2,000 more, he said later, if America had been willing to take any. A hero might have got involved in the stress and distress of individual cases. He avoided that by treating them... Question: What is the best title for the passage? Answer:

OPTIONS:
- A job well done
- A risky rescue
- A group of lucky children
- A living legend

Answer: A job well done

Read the following article and answer the question. Article: If parents bring up child with the aim of turning the child into a genius , they will cause great damage to him. According to several leading educational psychologists , this is one of the biggest mistakes which some parents make. Generally, the child will understand very well what the parent expects, and will fail. Unrealistic parental expectations can cause great damage to children. However, if parents are not unrealistic about what they expect their children to do, but are hopeful in a sensible way, the child may succeed in doing very well -- especially if the parents are very supportive (,) of their child. Michael Li is very lucky. He is very fond of music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. They even drive him 50 kilometres twice a week for violin lessons. Although Michael's mother knows very little about music, Michael's father plays the trumpet in a large orchestra .

Although both his parents are successful musicians, they set too high a standard for Winston. They want their son to be as successful as they are and so they enter him in every piano competition held. They are very unhappy when he does not win.
