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 .
How Much to Tip
You’re out to dinner . The food is delicious and the service is fine . You decide to leave a big fat tip . Why ? The answer may not be as simple as you think .Tipping , psychologists have found , is not just about service . Instead , studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter’s choice of words , to how they carry themselves while taking orders , to the bill’s total . Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night .“Studies before have shown that mimicry brings into positive feelings for the mimicker ,”wrote Rick van Baaren , a social psychology professor . “ There studies show that people who are being mimicked become more generous toward the person who mimics thorn .”
So Rick van Baaren divided 59 waiters into two groups . He requested that half serve with a phrase such as “ Coming up ! ” Those in the other half were instructed to repeat to orders and preferences back to the customers . Rick van Baaren then compared their take home . The results were clear－it plays to mimic your customers . The copycat waiters earned almost double the amount of tips to the other group .
Leonard Green and Joe Myerson , psychologists at Washington University in St . Louis found the generosity of a tipper may be limited by his bill . After research on the 1,000 tips left for waiters , cab drivers , hair stylists , they found tip percentages in these three areas dropped as customers’bills went up . In fact , tip percentages appear to plateau when bills topped ＄100 and a bill for ＄200 made the worker gain no bigger percentage tip than a hill for ＄100 .
“That’s also a point of tipping ,” Green says . “ You have to give a little extra to the cab driver for being there to pack you up and something to the waiter for being there to serve you . If they weren’t there you’d never get any service . So part of the idea of a tip is for just being there .”
1.How many factors affecting the customers’ tipping are mentioned in the passage ?
A.1 B.2 C.3 D.4
2.These studies show that ______.
A.tipping can be affected by physical reactions to many different waiter’s factors
B.people who are being mimicked usually tip less to the person who mimics them
C.the mimic waiters can get almost twice as much money as the other group
D.mimicry makes the mimicker feel bad
3.According to the passage , which of the following will be likely to show the right change of the tip percentages ?
4.We know from the passage that the writer seems to ______.
A.object to Mr Green’s idea about tipping
B.think part of Mr Green’s explanation is reasonable
C.give his generous tip to waiters very often
D.support the opinions of Mr Green and Rick van Baaren about tipping
It gives me great pleasure today to say a few words in praise of a man we will all miss very much . To be honest , I can’t imagine we will do without him when he’s gone . Bill Masters almost single-handed built up our sales force in the Houston area and developed the market position that we enjoy today .In only six years , he has brought the firm from a very low fifth position in the area sales to the point where we now outsell all but one of our competitors . Not omly have we got 37 per cent of the market under Bill’s leadership ; we are increasing our share with each passing month .
As you know , the company has moved Bill to northern California to work his sales magic in one of this company’s competitive areas . But we know that if anyone can do it , Bill Masters can , and I know you all join me in wishing him the best of luck in his new work .

阅读下面短文，从短文后所给各题的四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项。
In recent years many countries of the world have been faced with the problem of how to make their workers more productive . Some experts say the 21 is to make jobs more varied . But do more varied jobs 22 greater productivity ?There is evidence to suggest that 23 variety certainly makes the worker’s life more enjoyable , it doesn’t 24 make him work harder . As far as increasing productivity is concerned , then , 25 is not an improtant factor .
Other experts feel that giving the worker 26 to do his job in his own way is important , and there is no doubt that this is ture . The 27 is that this kind of freedom can’t easily be given in the modern factory with its complicated machinery which must be used in a 28 way . Thus while freedom of choice may be important , there is usually very little that can be done to 44 it .
Another important 30 is how much each worker 31 to the product he is making . In most factories the worker 32 only one small part of the product . Some car factories are now 33 with having many small production lines rather than one large one , so that each worker contributes more to the production of the cars on his 34 . It would seem that not only is degree of worker contribution an important factor 35 it is one we can do something about .
To what 36 does more money lead to greater productivity ? The workers themselves certainly think this is 37 . But perhaps they want more money only because the work they do is so boring , 38 just lets them enjoy their spare time more . A 39 argument may explain demands for shorter working hours . Perhaps if we 40 making their jobs more interesting , they will neither want more money , nor will shorter working hours be so important to the .
