4. Passage 11 Many children use the Internet to get useful knowledge and information， and to relax in their free time. But some of them are not using in a good way. Here are some rules to make sure you are safe and have fun on the Internet. Make rules for Internet use with your parents. For example， when you can go online， for how long and what activities you can go online. Don‘t give your password to anyone else， and never leak out the following information---your real name， home address， age， school， phone number or other personal information. Check with your parents before giving out a credit card number. Never send a photo of yourself to someone in e-mail unless your parents say it‘s OK. Check with your parents before going into a chat room. Different chat rooms have different rules and attract different kinds of people. You and your parents must make sure it‘s a right place for you. Never agree to meet someone you met on the Internet without your parent‘s permission. Never meet anyone you met on line alone. Always remember that people online may not be who they say they are. Treat everyone online as strangers. If something you see or read online makes you uncomfortable， leave the site. Tell a parent or teacher right away. Treat other people as you‗d like to be treated. Never use bad language. Remember—not everything you read on the Internet is true. If your parents don‘t agree， never( ).

4. Passage 7 Greek soldiers sent messages by turning their shields toward the sun. The flashes reflected light could be seen several miles away. The enemy did not know what the flashes meant， but other Greek soldiers could understand the message. Roman soldiers in some places built long rows of signal towers. When they had a message to send， the soldiers shouted it from tower to tower. If there were enough towers and soldiers with loud voices， important news could be sent quickly over distance. In Africa， people learn to send messages by beating on a series of large drums. Each drum was kept within hearing distance of the next one. The drum beats were sent out in a special way that all the drummers understood. Though the messages were simple， they could be sent at great speed for hundreds of miles. In the eighteenth century， a French engineer found a new way to send short messages. In this way， a person held a flag in each hand and the arms were moved to various positions representing different letters of the alphabet. It was like spelling out words with flags and arms. Over a long period of time， people sent messages by all these different ways. However， not until the telephone was invented in America in the nineteenth century could people send speeches sounds over a great distance in just a few seconds. The( )way of communication made use of visible signs.

A. 　French

B. 　 Roman

C. 　 African

D. 　 American

3. Passage 8 Upon reaching an appropriate age (usually between 18 and 21 years)， children are encouraged， but not forced， to ―leave the nest‖ and begin an independent life. After children leave home they often find social relationship and financial support outside the family. Parents do not arrange marriages for their children， nor do children usually ask permission of their parents to get married. Romantic love is most often the basis for marriage in the United States; young adults meet their future spouses through other friends， at jobs， and in organizations and religious institutions. Although children choose their own spouses， they still hope their parents will approve of their choices. In many families， parents feel that children should make major life decisions by themselves. A parent may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do precisely the opposite of what their parents wish in order to assert their independence. A son may deliberately decide not to go into his father‘s business because of a fear that he will lose his autonomy in his father‘s workplace. This independence from parents is not an indication that parents and children do not love each other. Strong love between parents and children is universal and this is no exception in the American family. Coexisting with such love in the American family are cultural values of self – reliance and independence. Based on the passage， it can be assumed that( ).

A. 　 American young adults are likely to follow the suit of their parents

B. 　 most American people never make major decisions for their children

C. 　 American young adults possess cultural values of independence

D. 　 once a young person steps into his twenties， he will leave his home permanently

5. Passage 14 Shortly after graduation， it is time for you to start the next phase of your life. You will begin your first “real job.” Generally speaking， most of what you have learned in school will not prepare you for this. There is a big difference between being a student and being an employee. Certainly， more will be expected of you. The best career-related advice I ever received came from my former boss on my first day of work. She told me to listen and observe before suggesting any changes. I took that advice and have used it in other situations， both in and out of the workplace. While innovation is a good thing， it is important to be mindful of dynamics of the workplace. If you are entering an environment where routines are already in place， a newcomer walking in and talking about “better ways” to do things， will often be met with negative reactions. Why? First， you know nothing about why they do things the way they do. Second， you haven＇t gained the trust of your co-workers. Finally， people， by nature， are threatened by changes. By listening and observing， you will gain a lot. You will learn about the environment of which you are now a part. You will find out more about the people you are working with. You may save yourself from making a major， public mistake—you are the new kid on the block while your co-workers have been around longer. You can learn from their collective experience. This passage is useful in helping you.

A. 　to find a job as quickly as possible

B. 　tofind a satisfactory first ―real‖ job

C. 　to get promoted soon

D. 　to leave a good impression on your co-workers

29.To make a living as a door-to-door( )demands courage because the door may shut in your face at any time.

A. 　attendant

B. 　 dealer

C. 　 carpenter

D. 　 salesman

4. Passage 6 Community service is an important component of education here at our university. We encourage all students to volunteer for at least one community activity before they graduate. A new community program called ―One On One‖ helps elementary students who‘ve fallen behind. Your education majors might be especially interested in it because it offers the opportunity to do some teaching， that is， tutoring in Math and English. You‘d have to volunteer two hours a week for one semester. You can choose help a child with Math， English， or both. Half-hour lesson are fine， so you could do a half hour of each subject two days a week. Professor Dodge will act as a mentor to the tutors ---- he‘ll be available to help you with lesson plans or to offer suggestions for activities. He has office hours every Tuesday and Thursday afternoon. You can sign up for the program with him and begin the tutoring next week. I‘m sure you will enjoy this community service and you‘ll gain valuable experience at the same time. It looks good on your resume， too， showing that you‘ve had experience with children and that you care about your community. If you‘d like to sign up， or if you have any questions， stop by Professor Dodge‘s office this week. What should students interested in the tutorials do?

A. 　Contact the elementary school.

B. 　Sign up for a special class.

C. 　Submit a resume to the dean.

3. Passage 19 Throughout her working life， a ship — like a motorcar — must be serviced regularly if she is to remain efficient. After a period at sea she must be overall checked and any necessary repairs must be made. There are also instances when a ship must be converted from being one kind of carrier to another. Most of today‘s oil， for example， is carried by huge super-tankers. The smaller tankers， many of which are still in good condition， can be converted into bulk carriers(散货船) for the transport of sugar， coal or ore. Conversion or repair work is carried out in a dry dock， a huge hole cut into the ground and lined with concrete. At one end are large gates separating the dock from the river or sea. When these gates are opened， water pours into the dock and fills it. A ship can then enter the dock， where it is carefully fastened in an upright position. When the ship is positioned inside the dock， the gates are closed and the water is pumped out. The vessel slowly settles on to wooden blocks. Wooden supporters are put in position between the ship and the sides of the dock to prevent her from rolling over. Great care is taken to make sure that the ship rests evenly on the keel(龙骨)blocks to prevent damage being done. As soon as the ship is firmly positioned， repair or conversion work can begin on her body or superstructure. We can infer that a dry dock( ).

A. 　is built by the water

B. 　is built far from the water

C. 　is built under the water
