51 The average American moves every five years．People drive straight into their garages, hire lawn services, hang out in their backyards instead of their front porches (前走廊)．These days, neighbors don't even know each other's names．
Good neighbors and good friends are a lot like electricity or running water52
The surprising thing is that all it takes to strengthen your relationship with friends and
neighbors is respect for their feelings, concern for their property, and a helping hand when it's needed． 53
First, be a true friend to people around you． 54 That is to say, A true friend is one who stays true through it all –marriage, parenthood, new jobs, new homes, or even losses．That situations change doesn’t mean the person has to．
Besides, friendships fade away if there isn’t a balance between the give and the take． 55 Be sensitive to how much your friend can and can’t offer you ---time, energy, or help---and don’t step over the line．Remember: friendships that tire each other will not last．If a friendship is out of balance in this way, you’ll need to consider the situation．
A．Modern life is a lot less to the advantage of friendships and neighborliness than it used to be．
B．A friend in need is a friend indeed．
C．We don’t know how much we depend on them until we lose them．
D．Here’re two important ways to deepen your friendship with people around in your life．
E．A true friend doesn’t flee when changes come about．
F．Take your time, please．
G．So make sure you aren’t being a burden to your friends．
Everyday we go to school and listen to the teacher, and the teacher will ask us some questions. Sometimes, the classmates will ask your opinions of the work of the class. When you are telling others in the class what you have found out about these topics, remember that they must be able to hear what you are saying. You are not taking part in a family conversation or having a chat（闲谈）with friends—you are in a slightly unnatural situation where a large group of people will remain silent, waiting to hear what you have to say. You must speak so that they can hear you—loudly enough and clearly enough but without trying to shout of appearing to force yourself.
Remember, too, that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you. The person you are seeing will try to put you at your ease（轻松）but the situation is somewhat（一点儿）different from that of an ordinary conversation. You must take special care that you can be heard.
48. When you speak to the class, you should speak ________.

Bollworms are a traditional threat to cotton crops．Young ones feed on the boll, the part of the
cotton plant that contains the seeds．
A bacterium known as Bt is able to kill bollworms and some other pests．Bt is short form for Bacillus thuringiensis．It was discovered in the early twentieth century．Farmers began using Bt as a natural pesticide（杀虫剂）．
Then，in the 1990s，researchers found a way to grow cotton plants that contain a Bt gene．The genetically modified cotton plant produces toxins that kill bollworms．Farmers around the world are now growing an estimated fourteen million hectares of Bt cotton．
Cotton bollworms also attack other crops．But scientists in China recently reported that Bt cotton may help suppress bollworm in other crops growing nearby．
The study involved crops grown in six provinces of northern China between 1992 and 2008.The study area contained three million hectares of cotton and twenty-two million hectares of corn，peanuts，soybeans and vegetables．
The researchers say the study suggested that Bt cotton not only controls bollworm on the transgenic cotton，but also may reduce its presence on other crops．And that reduction，they say，may decrease the need for insecticide use in general．
But the researchers also pointed out concerns．They say bollworms could develop resistance to the cotton plants designed to resist them．And they noted that insects called mirids have become “key pests” of cotton in China．They said this is because of a decrease in pesticide use made possible by Bt cotton．
The researchers say they do not believe that Bt cotton alone can solve all insect problems．Instead，they say farmers in China should consider it just one part of pest management systems．
44．What is Bt in this passage?
A．It's a kind of hi-tech invention． B．It's a natural bacterium．
C．It's a kind of pest． D．It's a man-made pesticide．
45．Bt cotton has all the advantages EXCEPT that ________．
A．it resists bollworms

C．it reduces the use of insecticide
D．it helps to develop new insects
46．The underlined word “ones” in the first paragraph refers to ________．
A．bollworms B．cotton crops C．cotton seeds D．pests
47．From the passage，we can infer ________．
A．farmers around the world are now growing a large area of Bt cotton
B．researchers are probably now searching for new ways to solve other cotton problems
C．bollworms could not exist in Bt cotton any longer
D．Chinese scientists found the way to grow Bt cotton
“Sesame Street” has been called “the longest street in the world”. That is because the television program by that name can now be seen in so many parts of the world. That program became one of American’s exports soon after it went on the air in New York in 1969.
In the United States more than six million children watch the program regularly. The viewers include more than half the nation’s pre-school children, from every kind of economic(经济的), racial(种族的), and geographical group.
Although some educators object to certain elements in the program, parents praise it highly. Many teachers also consider it a great help, though some teachers find that problems arise when first graders who have learned from “Sesame Street” are in the same class with children who have not watched the program.
Tests have shown that children from all racial, geographical, and economic backgrounds have benefited from watching it. Those who watch it five times a week learn more than occasional(偶然的) viewers. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.
The programs all use songs, stories, jokes, and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate letters.
Why has “Sesame Street” been so much more successful than other children’s shows? Many reasons have been suggested. People mention the educational theories(理论) of its creators, the support by the government and private(私人的) businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching feel able to learn. The child finds himself learning, and he wants to learn more.
40. “Sesame Street” is actually _______.
A. a street in the US B. a program for children
C. a program for teachers D. a program for students
41. Children who often watch the program _______.
A. can have problems in school
B. will find it a great help
C. will take no interest in their studies
D. will be well educated
42. Why is “Sesame Street” so popular in the world?
A. Because it is supported by the government and businesses.
B. Because it uses a variety of skillful tricks.
C. Because mothers watch it along with their children.
D. Because it makes every child watching it feel able to learn.
43. The best title for this passage can be _______.
A. TV Programs B. Educating Children
C. Sesame Street D. A Great Success
