单选题Trees are useful to man in three very important ways: they provide him with wood and other products; they give him shade; and they help to prevent droughts (干旱) and floods. Unfortunately, man has not realized that the third of these services is the most important. Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire, but, without its trees, its soil became hard and poor. When the empire fell to pieces, the home country found itself faced by flood and starvation. Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade villagers to see this. The villagers want wood to cook their food with; and they can earn money by selling wood. They are usually too lazy to plant and look after the trees. So, unless the government has a good system of control, or can educate the people, the forests will slowly disappear. This does not only mean that the villagers" children and grandchildren will have fewer trees. The results are even more serious, for where there are trees their roots break the soil up allowing the rain to sink in--and also bind the soil, thus preventing its being washed away easily but where there are no trees, the rain falls on hard ground and flows away from the surface, causing flood.

单选题Marley Dias loves nothing more than getting lost in a book. But the books she was reading at school were starting to get on her nerves . She enjoyed Where the Red Fern Grows and The Shiloh Series , but those classics, found in so many primary school classrooms, were all about white boys or dogs—or white boys and their dogs. Black girls, like Marley, were almost never the main character. What she was noticing is actually a much bigger issue: fewer than 10 percent of children"s books released in 2015 had a black person as the main character, according to a yearly analysis by the Cooperative Children"s Book Center. In November 2015, Marley set out to gather 1,000 books with black girls as protagonists (主角). Her campaign called "#1000BlackGirlBooks" was a big success. （77） She far exceeded her goal and collected more than 10,000 books! "Through my campaign, I want to give kids a stronger sense of identity." Marley says. （78） "The biggest thing I"ve learned is that kids" voice need to be heard." In the future, Dias wants to be the editor (编辑) of her own magazine. She is already making the steps toward having a successful and meaningful career. At 11, she"s aware of the racism in the publishing industry. Like the television and movies, the publishing industry does not represent black girls or other people of color in positive ways. The whitewashing (漂白) in this industry extends beyond not having people of color as characters. In 2012, white men wrote 88% of the book reviews. In 2013, only about 2% of the books were about black characters. Then if there are people of color in the books, the publishers attempt to whitewash people of color on the covers. However, Dias is making it a little easier for other black girls searching for a character that is just like them. Her project is a positive step toward young black girls seeing and experiencing their lives in books.

单选题Heredity(遗传) is not the only thing that influences our color. Where we live and how we live after we are born are important too. For instance, our genes influence how fat or thin we are. But our weight depends mainly upon how much we eat and how much exercise we get. In the same way, our skin color depends to a large extent upon how much sunshine we get. When summer arrives and light—colored people go to the beaches, some will tan darkly, some will tan lightly and few will not tan at all. Each one has inherited a different ability to tan, but the differences do not appear until the conditions are right. An outdoor man will soon become pale if he changes to an indoor job, while a desk clerk will take on tan after a short vacation in the sun. Sometimes people decide that being tanned is better than being pale. Sometimes they decide the opposite. Centuries ago, most of the people in Europe were peasants and they had to work in the fields all day. Noblemen, on the other hand, did not have to work. They stayed indoors and remained pale. You could always tell a nobleman from a peasant because a peasant had a tan. As a result, a shin so pale that the veins (血管) showed was considered a mark of great beauty. During the Industrial Revolution things changed. Farmers left their fields and went to work in factories, mines and mills. Working for long hours in dimly—lit factories and mines made their skins pale. Wealthy people, however, could afford to travel so sunny countries. They had the leisure to lie around on the beaches and get tan. Having a tan became a sign of wealth. In Western Europe and North America pale skin is no longer desirable. Instead of bleaching themselves white with lemon juice, many women spend their time under a sun—lamp. The desire for a quick tan has led to the invention of pills and lotions (涂剂) that darken the skin artificially without exposure to sunlight. These pills and lotions can be bought by anyone at any drugstore. A rich man can spend hundreds of dollars on a vacation in the sunny West Indies and get his suntan there. But his lowest—paid clerk can have what looks like the same tan out of a bottle for a few cents.
