13.Does the Yangtze River still have baiji(白鳍豚),the graceful,grey dolphin with tiny eyes and a long narrow beak?
Since November 6,a team of scientists from China,Switzerland,the United Kingdom,the United States,Germany and Japan had been searching for any sign of the freshwater dolphin in the middle and lower sections of the river.After six weeks,they came back empty-handed.Wang Ding,head of the team,said he had seen a sharp drop in the baiji population over the past few decades.However,he was still unwilling to call the species extinct and added,"We will try every effort to save them as long as they are not found to be extinct."
As one of the world's oldest dolphin species,the baiji is shy and nearly blind.It dates back about 20 million years and is found only in the Yangtze River.It's listed as one of the 12 most endangered animal species in the world.
Around 400 baiji were believed to be living in the Yangtze until the 1 980s.In 1997,a survey spotted 13.Two years later their number was down to zero.
  The rapi d disappearance of this dolphin over the past two decades coincided(巧合) with the rapid expansion of economic development along the river.Resea rchers on some dead baiji collected in recent years showed that more than 90 percent of the deaths were caused by human activities.
One reason is that over-fishing has cut the dolphin's food sources.Dams built along the river and neighbouring waterways have also kept them from swimming into and out of their habitats.Meanwhile,waste discharge(排放) has seriously polluted the river.And heavy river traffic has greatly reduced their living space.
The disappearance of the baiji would be the first case of a large aquatic(水生的) mammal being driven to extinction since hunting killed off the monk seal around 1952.
42.This passage mainly tells usA.
A.the fact that Baiji is in danger and the reason why its number reduces
B.people are trying efforts to save Baij i as long as they find them
C.human activities have caused 90 percent of Baiji's deaths
D.how serious the pollution is long the Yangtze River
43.It is known from the passage thatB.
A.scientists from foreign countries have searched for Baiji for 6 years
B.Baiji is a large aquatic mammal which is in danger of extinction
C.Baiji becomes endangered all because of human's activities
D.there are 12 endangered species altogether in the world
44.We can infer from the passage thatA.
A.riverside constructions have affected the living environment of animals
B.Baiji is one of the world's oldest species and lives longer than humans
C.it is the waste discharge that has poisoned Baiji in Yangtze River
D.nowadays scientists are no longer able to save Baiji at all
45.This passage is most probably taken fromD.
A.a student's diary              B.a tour guidebook
C.a Biology textbook              D.a science magazine.
8.Eat like a king in the morning,a prince at noon,and a peasant at night.This saying is all about the importance of breakfast.And now scientists can tell us just why it's so important.According to a study carried out at Imperial College London,UK,skipping the first meal of the day not only means you eat more at lunch,but also that your brain wants to find more unhealthy foods.
The study suggests that there is a special part of our brain called the orbitofrontal cortex (眶额皮层),which plays an important part in making choices about what we eat.It is used for identifying the taste of food,especially when skipping breakfast.It is more likely to target high-calorie foods when you're on an empty stomach.
Scientists did an experiment on this.Dr Tony Goldstone from Imperial College London,scanned (扫描) the brains of 21men and women,around the age of 25.On the first day,these people skipped breakfast before the scans.On the second day,they had cereal (谷物),bread and jam as breakfast.After the scan on both days,they had their lunch.
When the volunteers had skipped breakfast,they ate around 20percent more at lunch,compared with days when they had eaten breakfast.Their brain scans also showed the orbitofrontal cortex was especially responsive to high-calorie foods."We believe that bit identifies the value of foods-how pleasant,how delicious something is,"Goldstone told The Guardian.
28.From Paragraph 1,we learn thatA.
A.scientists found out why eating breakfast is important
B.it's easy to lose weight without breakfast
C.there's no need to have good food for supper
D.eating breakfast makes your brain smarter
29.Which is the correct order for the experiment on the first day?C
①The volunteers skipped breakfast.
②The volunteers had lunch.
③The volunteers had a brain scan.
A.①②③B.③②①C.①③②D.③①②
30.Which of the following is NOT true about the orbitofrontal cortex?B
A.It is part of our brain.
B.It tells people to eat breakfast.
C.It decides which food we like.
D.It is active toward high-calorie foods.
31.Which of the following can be the title for this passage?A
A.Breakfast still most important
B.Three meals a day
C.Experiments on breakfast
D.Researches on lunch.
