20．Bissel is a small village of the West Sahara．It lies next to a l.5-square-kilometer oasis（绿洲），from where three days and nights are generally required to go out of the desert．However，before Ken Levin discovered it in 1926，none of the Bissel villagers had ever walked out of the desert．Reportedly，they were not unwilling to leave this barren land．Many had previously tried but failed，always somehow finding themselves back at the oasis after several days of trying to walk out．
When interviewed by Ken Levin，an expert at the British Royal College of Sciences，the villagers explained that no matter which direction they walked it always brought them back to the village．Why couldn't the Bissel villagers walk out of the desert？Levin was very puzzled．He had，by himself，managed to walk north from the village and reach the nearest town in three and a half days．He decided to carry out an experiment to solve the mystery．He and a Bissel villager called Argutel，would walk out of the desert together．They prepared enough water for a half-a-month journey and two camels．But this time Ken Levin didn't bring his compass．Levin would follow Argutel．
Ten days later，they had walked for about 500miles but were still in the desert．On the 11th morning，an oasis came into their view．They were back at Bissel．Levin now understood why the Bissel people couldn't escape the desert．They had no knowledge of the North Star，which had for centuries provided sailors and other travelers with a point of direction．In the desert，if a person goes forward relying only on their senses，they will not be able to travel in a straight line．Rather they will travel in a very large circle and eventually track back to where they began．Levin explained to Argutel the function of the North Star and said，"As long as you rest in the daytime and walk towards the brightest star at night，you would be able to walk out of the desert．"Argutel did as he was told．Three days later，he came to the edge of the desert．
Now in the West Sahara，Bissel has become a bright pearl，where tens of thousands of tourists come every year．Argutel's bronze statue stands in the center of the town．On its base are the words：
．

14．Starting the day on an egg could keep your blood pressure （血压） under control，research suggests．Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressurelowering drugs．
The research，from the University of Alberta in Canada，showed that when eggs come in contact with stomach enzymes （酶） they produce a protein that acts in the same way as ACE inhibitors used to treat heart disease，but more work is needed to show the effects outside a lab and in the human body．
Earlier this month，British researchers declared that，opposite to popular beliefs，it is healthy to go to work on an egg．They concluded that the type of cholesterol （胆固醇） found in eggs has little effect on increasing heart disease risks．
Researcher Professor Bruce Griffin，from the University of Surrey，said，"The wrong beliefs linking egg eating to high blood cholesterol and heart disease must be corrected．The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the relatively small amounts of cholesterol found in eggs．The UK public do not need to be limiting the number of eggs they eat．They can be encouraged to include them in a healthy diet as they are one of nature's most nutritious foods．"
The British Heart Foundation has dropped its threeeggaweek limit．However，almost half of Britons believe the limit still applies．

32．From the text we know that"ACE inhibitors"areC．
A．a kind of protein
B．a kind of illness
C．a kind of medicine
D．a kind of food
33．According to what Professor Bruce said，eggsB．
A．are the most nutritious food
B．can be included in a healthy diet
C．have no effect on blood cholesterol
D．are forbidden to be eaten in the UK
34．We can infer from the text thatD．
A．drugs to lower blood pressure will be replaced by eating eggs
B．stomach enzymes mixed with eggs can cure heart diseases
C．there is relatively quite a little cholesterol found in eggs
D．about 50% of Britons think eating an egg a day is bad for their health
35．The text is meantA．
A．to introduce scientific findings about eggs
B．to report a medicine made from eggs
C．to tell people how to lower their blood pressure
D．to advise people to eat as many eggs as possible．

1．ratherthan（与其..不如） take the aeroplane all the way，they decided to fly to Vancouver and then take the train west to east across Canada．

18．What she said just now made us sad．

19．Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings．It is caused mainly by industrial underwater explosions，ocean drilling，and ship engines．
Some scientists have proposed （提议） setting a noise limit of one hundred and twenty decibels （分贝） in oceans．They have observed that noises at the level can frighten and confuse whales．
A team of American and Canadian scientists discovered that loud noises could seriously injure some animals．They found that powerful underwater explosions were causing whales in the area to lose their hearing．This seriously affected the whales'ability to exchange information and find their way．Some of the whales even died．
Some researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels．They say such a limit would mean an end to important industrial and scientific research．Scientists do not know how much and what kinds of noises are harmful to ocean animals．However，many scientists agree that noise is a greater danger than they believed．They want to prevent noises from harming creatures （生物） in the ocean．
29．Concerning the effect of noises on whales，which of the following is TRUE？B
A．They are deaf to noises．
B．Noises at a certain level may hurt them．
C．Noises could kill them．
D．Noises will cause them to lose their eyesight．
30．Some scientists think that the noise limit of one hundred and twenty decibels wouldA．
A．prevent them doing their research work
B．benefit them a lot in their research work
C．do good to their health
D．increase the industrial output
31．According to the last paragraph，what will scientists most probably do in the future？D
A．They will study the effect of different noises in the sea．
B．They will work hard to make no noise．
C．They will never do any scientific research in the sea．
D．They will protect sea animals from harmful noises．
