Section B
Directions: Read the following passage. Answer the questions according to the information given in the passage and required words limit.
Scientists have determined it's not advisable to hurry marriage. But what’s the best age to wed?
When Avril Lavigne announced she was splitting from her husband, comments from her friends suggested that she was only 21 when she tied the knot and later she said that she realized she'd been too young to make such a life-altering decision. Could fellow young celebrity divorcées(離婚者) Reese Witherspoon, Kate Hudson, and Britney Spears have also hit the same age-related issue?
The Magic Number
There are practical reasons for the mid-20s dividing line, and most of them boil down to two biggies: education and money. 
It turns out that the more years of higher education a woman has under her belt on her wedding day, the lower the chances that she'll get divorced ... and by 25, you're more likely to have earned a degree or two. Educated women tend to be more confident about who they are and less willing to settle for a man who doesn't meet their standards.
Odds(可能性) are that by 25 you're also supporting yourself, so there's less incentive(刺激; 鼓勵(lì))for you to rush into marriage because you're seeking financial security from him. But the marriage-related benefits of working and having money of your own go beyond feeling secure. Learning to budget your cash carefully when you're single will help you avoid financial problems—one of the main causes of couple fights—for the rest of your life. 
Knowing the Real You
At 25, you've had time for some crucial life experiences, including a relationship or two that may have improved your Mr. Right radar. You've probably dated enough to have a better idea of what you don't want in a man, which makes it easier to know what you can live with and can't live without. 
Perhaps the most important aspect of waiting is that you'll know what your goals and values really are. While you don't want to marry someone just like you, marriage is a lot easier if you two share a similar outlook on life.
Twenty-four and already married to the man of your dreams? Don't worry: Many young marriages survive. But given the choice, you might consider putting off the big day until your mid-20s or later.
81. What main factors influence the mid-20s dividing line? (No more than 3 words)

82. According to the author, why does a couple probably fight?(No more than 4 words) _______________________________________________________________________________

Domestic airline passengers will be able to make phone calls and send e-mails from the sky from next year, a local carrier has said.
Shenzhen Airlines said on Monday it has signed an agreement with Geneva-based On-Air to provide passengers with in-flight communications services on all its planes by the end of 2009. The service will be introduced on three aircraft ahead of the 2008 Olympics, on two routes----from Shenzhen to Beijing and Shenzhen to Shanghai, the airline said.

Despite the introduction of the new service, passengers will still be prevented from using their cell phones and laptops when the plane is taking off and landing, or flying at less than 3,000 m above sea level, the official said.
The official said the new service would not lead to an increase in ticket prices, but users of Chinese mobile-phone services will be charged the international roaming rate for any calls made from the sky.
Shenzhen Airlines is the first Chinese carrier to provide such in-flight communications services.

Farmers use different kinds of soil conservation methods to protect their land from damage by farming and the forces of nature . One important form of soil conservation is the use of windbreaks . Windbreaks are barriers formed by trees and other plants with many leaves . Farmers plant them in lines around their fields .
Windbreaks stop the wind from blowing soil away . They also keep the wind from destroying or damaging crops . They are very important for growing grains , such as wheat . There have been studies done on windbreaks in parts of West Africa , for example . These found that grain harvests can be twenty percent higher in fields protected by windbreaks compared to fields without such protection .
However , windbreaks seem to work best when they allow a little wind to pass through . If the wall of trees and plants stops wind completely , then violent air motions will take place close to the ground . These motions will lift soil into the air where it will be blown away .
For this reason , a windbreaks is best if it has only sixty to eighty percent of the trees and plants needed to make a solid line . An easy role to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreaks .
These should be at least two lines in each windbreak . One line should be large trees . The second line , right next to it , can be shorter trees and other plants with leaves . Locally grown trees and plants are best for windbreaks .
1.What is the best title for the passage?
A.Building a windbreak to protect soil
B.Building a windbreak to protect crops
C.Using a windbreak to improve grains
D.Using a windbreak to improve plants
2.In the fifth paragraph the author tells us windbreaks______.
A.do not work at all
B.do not stop wind fully
C.will not take place
D.will not allow wind to pass through
3.According to the passage , which of the following statement is wrong ?
A.Windbreaks are barriers .
B.Windbreaks can be used to make fences .
C.In general , there are two lines in all in every windbreak .
D.Windbreaks can protect areas .

Schedules, as the 21st century people know, simply did not exist in the 17th and 18th centuries. We are upset if a plane arrives an hour late. Our ancestors weren’t upset if an April ship didn’t show up until June. They began to worry in July and were often happy when it showed up in August. When a long-distance ship finally did get to the port, the whole city became busy and excited. Businessmen hurried down to check the goods they had ordered. The ship would probably stay in port for at least three days, often a week, to take on businessmen, give the sailors a rest, find out about the latest news, weather conditions, and so on.
Travel time could only be approximate. One never knew when the winds would be good. So even though “average sailing time” was given, time could change considerably, shortening the voyage by up to 25% or putting it off by up to 500% or more! The average run from England to Boston was about a month and a half, but there were also voyages of three months. One voyage in 1640 lasted six months!
Travel time is not the same in both directions, due to the winds and currents. This is especially true in the Caribbean, where winds are from the southeast the entire year. Ships sailing west across the Atlantic spend longer than ships sailing east, and the contrary winds can prevent a ship from actually making it to the harbor even if it gets close. One ship was held off the North Carolina coast for 17 days before being able to land!
1. What can we learn from the first paragraph?
A. No sailor was allowed to have fun when the ship reached land.
B. People in ancient times didn’t care about other people’s safety.
C. The ship would leave for a voyage when all of the preparations were made.
D. A long-distance ship would create a lot of excitement in the place where it landed.
2. According to the passage, travel time can’t be fixed due to ___________ .
A. the people at the port                  B. average sailing time
C. the changeable climate                    D. the businessmen and the sailors
3. The underlined word “currents” in the third paragraph means __________ .
A. the movement of water                   B. the movement of winds
C. direction of the traveling ship      D. travel time of ships

Texting is a great way to communicate and teenagers are doing just that. New research shows that on average, teens are sending 2,000 text messages a month, and doctors say it’s causing injuries.
13-year-old Bailey Baker keeps using her thumbs, sending text messages to her friends again and again. The past March may have been her best month ever, texting 8,000 times. Now, she says she’s feeling the pain. “Just mainly back and neck problems and thumb numbness,” she says.
Baylor-Garland Dr. Jane Sadler is seeing more and more teens who simply text until it hurts. She says parents, including Bailey’s mom, have no idea how much their kids are texting. “I was thinking she was texting about 25 texts a day,” says Lisa Baker. “Wrong! We’ve uncovered a problem.” It didn’t take Dr. Sadler long to find the problem. She gave Bailey the once-over and learnt that Bailey had developed Texting Teen Tendinitis(肌腱炎)
“A lot of them report pain in their thumbs, back and neck,” says Dr. Sadler. “When we look into it and examine a little bit further, we see texting is the main cause of the problem.” Dr. Sadler says back pain is caused by poor posture while texting. Bailey often texts for up to 2 hours a day; that’s a lot of wear and tear on the thumbs which over time, can break down. Dr. Sadler tells over-texting teens to look into the future. “What I tell them is ‘Hey, you might be normal now, but when you are 40 or 50, you can get arthritis (關(guān)節(jié)炎).’”
Dr. Sadler recommends limiting texting to 50 a day, and keeping good posture. Dr. Sadler also says touch screens are easier on the thumbs than keyboards and hand exercises are great to build up those muscles, making it easier to text.
1. How many text messages did Bailey Baker send a day on average last month?
A. Less than 226.   B. About 230.        C. About 267.        D. More than 300.
2. Because of texting, Bailey Baker suffers from the following problems EXCEPT ______.
A. back pain          B. neck pain          C. headache           D. thumb numbness
3. What does the underlined part in Paragraph 3 mean?
A. She gave Bailey Baker a quick examination.
B. She solved Bailey Baker’s problem at once.
C. She gave Bailey Baker a piece of advice.
D. She let Bailey Baker send a text message again.
4. What can we conclude from Paragraph 4?
A. Teenagers won’t get hurt if they stop texting right now.
B. Poor posture while texting is the main cause of injuries.
C. Thumbs won’t ache if teens text for no more than 2 hours a day.
D. Over-texting may have a bad effect on people in the long run.
