We know that many animals do not stay in one place．Birds, fish and other animals move from one place to another 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（遷移）is probably the migration of the fish, which is called “salmon”．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 there．In northern Europe, there is a kind of mice．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 lobsters（龍蝦）．Every year, when the season of 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, but at other times we don’t．Maybe living things just like to travel．

1．Most animals move from one place to another at a certain time to __________ ．

     A．give birth                                  B．enjoy warmer weather

     C．find food more easily                        D．find beautiful places

THE BRONTE FAMILY

Yorkshire, England was the setting for two great novels (小說) of the 19th century. These were Charlotte Bronte’s Jane Eyre and Emily Bronte’s Wuthering Heights. The youngest sister, Anne, was also a gifted novelist, and her books have the same extraordinary quality as her sisters’.

Their father was Patrick Bronte, born in Ireland. He moved with his wife, Maria Bronte, and their six small children to Haworth in Yorkshire in 1820. Soon after, Mrs. Bronte and the two eldest children died, leaving the father to care of the remaining three girls and a boy.

Charlotte was born in 1816. Emily was born in 1818 and Anne in 1820. Their brother Branwell was born in 1817. Left to themselves, the children wrote and told stories and walked over the hills. They grew up largely self-educated. Branwell showed a great interest in drawing. The girls were determined to earn money for his art education. They took positions as teachers or taught children in their homes.

As children they had all written many stories. Charlotte, as a young girl, alone wrote 22 books, each with 60 to 100 pages of small handwriting. Therefore, they turned to writing for income. By 1847, Charlotte had written The Professor; Emily, Wuthering Heights; and Anne, Agnes Grey. After much difficulty Anne and Emily found a publisher(出版商), but there was no interest shown in Charlotte’s book. (It was not published until 1859.) However, one publisher expressed an interest in seeing more of her works. Jane Eyre was already started, and she hurriedly finished it. It was accepted at once; thus each of the sisters had a book published in 1847.

Jane Eyre was immediately successful; the other two, however, did not do so well. People did not like Wuthering Heights. They said it was too wild, too animal-like. But gradually it came to be considered one of the finest novels in the English language. Emily lived only a short while after the publication of the book, and Anne died in 1849.

Charlotte published Shirley in 1849, and Villette in 1853. In 1854 she married Arthur Bell Nicholls. But only a year later, she died of tuberculosis(肺結(jié)核) as her sisters had.

We know from the text that      .

A. Jane Eyre was published in 1847    

B. Charlotte Bronte wrote 22 books in all

C. the Bronte sisters received good education     

D. Patrick Bronte helped his daughters with their writing

The underlined words “the other two” in the 5 th paragraph refer to      .

       A. Shirley and Villette   B. The Professor and Agnes Grey

       C. Agnes Grey and Wutheriing Heights   D. The Professor and wuthering Heights

What do we know about the Bronte sisters from the text?

       A. Their novels interested few publishers.

       B. None of them had more than two books published.

       C. None of them lived longer than 40 years old.

       D. Emily was the least successful of the three.

"Once you go down this path, it' s something you continually struggle with, which is exactly why the law is so important．The new law is not about me, it' s about the next generation of kids coming up．What we don ' t want is kids going down that path," he said．
Nearly 20% of Americans smoke and tobacco use kills about 440,000 people a year in the United States due to cancer, heart disease, and other serious diseases．
