    【题目】Have you ever tried to understand something new on your own but found it a bit too difficult in books or on the Internet? Don't be worried一you can get help at Khan Academy（可汗学院）．

    Khan Academy is an online learning website created in 2007 by Salman Khan, an American teacher. In order to provide "a free world-class education to anyone anywhere"，Khan offers more than 4,200 free micro lectures（讲座）atkhanacademy.org.

    The classes cover fields like mathematics, biology, chemistry and finance. They usually last for just 10 to 15 minutes. Unlike traditional classes, Khan mainly offers courses for students below college level. The classes can also help those who are planning to take the SAT, an exam often required for students who wish to enter a college or university in the US.

    First of all，enter the website with a personal e-mail account（帐户）．Your personal homepage at Khan Academy is designed to help you learn math. You can take a pre-test first to see your level. The academy then suggests exercises at the right level for you. It also allows you to watch videos and improve yourself until you reach level 5一the highest level.

    If you are interested in other subjects, click "LEARN" to see all topics on offer. Try "Art History"，for example. This will take you to all the things in that area like text articles, videos and questions. You can also put key words into the search box to see related topics.

    Don't worry if you find it difficult to follow the courses in English. The courses have been translated into other languages, such as Chinese. Hundreds of Khan's courses in Chinese can be found on Netease (www. 163. com)，which offers translations of courses from Harvard, Yafe, Oxford，Cambridge and other top universities.

    【题目】根据短文内容，回答下列问题。
    C
    阅读短文，并按要求完成下列句子。
    　　　　We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another place at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
    　　　　When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration is probably the migration of the fish which is called “salmon” (鲑鱼)．This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.
    　　　　Recently, scientists have studied the migration of a kind of lobster (龙虾)．Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another place, but at other times we don't. Maybe living things just like to travel.
    （1）The reason for most of the animals to move is .
    （2）Find the word in the passage which means“the movement from one place to another of a large group of animals” and writeit down here: .
    （3）The underlined word “There” in the second paragraph refers to (指的是).
