As many people hit middle age, they often start to notice that their memory and mental attention are not what they used to be. We suddenly can't remember where we put the keys just a moment ago, or an old friend's name, or the name of an old band we used to love. It happens to most of us, but is it unavoidable?
Scientists are increasingly showing that there's actually a lot that can be done. It turns that the brain needs exercise in much the same way as our muscles do, and the right mental workouts can improve our basic cognitive(认知) functions.
Now, a new San Francisco Web-based company has taken it a step further and developed the first "brain training program" designed to actually help people improve and regain their mental sharpness. Called Lumosity, it was designed by some of the leading experts from Stanford University. Lumosity is far more than an online place to exercise your mental skills. That's because they have combined these exercises with a Web-based program that allows you to systematically improve your memory and attention skills.
Apparently it works. One study showed students improved their scores on math tests by 34 percent after using Lumosity for six weeks, greater gains than those made by other students in the same class, who were not training with the Lumosity program. The company says its users have reported clearer and quicker thinking, improved memory for names, numbers, directions, increased alertness(警觉) and awareness, high mood, and better concentration at work or while driving.What is the purpose of Lumosity?
A.To exercise the brain and muscles. |
B.To combine exercises with a web-based program. |

B.Lumosity is unreasonable. |
C.Muscles don’t need exercise. |
D.Brains need exercise. |
What does the last paragraph mainly tell us?
A.Lumosity is an effective program. |
B.Users have improved their thinking. |
C.A company made a Lumosity trial. |
D.Lumosity was carried out in tests. |
The author explains the training results by________
A.making a comparison. |

Losing a baby tooth can be fun for a kid. You can put it under your pillow and look forward to finding some money there in the morning. And then you can watch your new permanent(永恒的) tooth grow in its place.
But if a permanent tooth falls out, that’s a problem. There isn’t another one under the gum(齿龈)that can replace it. Unfortunately, this happens to some older people. And if permanent teeth fall out or need to be pulled, an older person might need dentures.
Dentures, known as false teeth, are a set of replacement teeth for any teeth that are missing. There are partial dentures, which take the place of only a few teeth and prevent the others from changing position. If all the teeth are gone, the person would need complete dentures, which replace every tooth in the mouth.
Dentures can cause pains at first and take little time to get adjusted to. They also need special care. They should be brushed daily with a special denture brush and cleanser and soaked in denture solution when not in the mouth.
Dentures are important for older folks because, without teeth, it’s hard to smile, talk, and eat properly. But it can be a little weird if you see someone take out his or her dentures. It can also be strange to see someone, like a grandparent, without dentures in because he or she won’t have any teeth. Try not to make fun of the person because this could cause hurt feelings.
People usually lose their permanent teeth due to periodontal disease, or gum disease, which is caused by bacteria that attacks the gums. Diseased gums aren’t strong and healthy, so teeth can get loose and fall out. Older people often have many cavities(洞)that have been filled over the years, and these fillings can weaken over time, leading to more tooth decay.

A.should have a false tooth fixed in its place
B.have to put it under your pillow at once
C.will gain a permanent tooth in future
D.can exchange it for some money

A.should brush them with a special denture brush every few days
B.will take a very long time to adjust himself or herself to them

69.Which of the following is NOT true according to the passage?
A.Partial dentures can prevent the remaining teeth from changing position.
B.Old people will find it hard to smile, talk, and eat properly without teeth.
C.A person’s teeth will possibly get loose if diseases strike his gums.
D.It is hard for a person to wear dentures if all his teeth have fallen out.
70.What does the underlined word “weird” mean in the fifth paragraph?
A.inconvenient B.excited C.uncomfortable D.impolite

During the twentieth century there has been a great change in the lives of women. A woman marrying at the end of the nineteenth century would probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which chance and health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty-five and can be expected to live another thirty-five years and she is likely to take paid work until sixty.
This important change in women’s life has only recently begun to have its full effect on women’s economic(经济的) position. Even a few years ago most girls left school and took a full-time job. However, when they married, they usually left work at once and never returned to it. Today the school-leaving age is sixteen; many girls stay at school after that age, and though women marry younger, more married women stay at work at least until shortly before their first child is born. Many more afterwards return to full-time or part-time work. Such changes have led to a new relationship in marriage, with the husband accepting a greater share of the duties and satisfactions of family life.
63. We are told that in a typical family in about 1900________.
A. few children died before they were five
B. seven or eight children lived to be more than five

64. One reason why the woman of today may take a job is that she _______________.
A. is younger when her children are old enough to look after themselves
B. does not like children herself
C. needn’t worry about food for her children
D. can be free from family duties when she reaches sixty
65. Many girls are now likely to _______________________.
A. give up their jobs after they are married
B. leave school as soon as they can
C. marry so that they can get a job
D. continue working until they are going to have a baby
66. According to the passage, it is now quite common for women to______________.
A. stay at home after leaving school

For almost two months Dominic York, a 23-year-old hairdresser, wandered about hospitals all night, wearing a white coat and pretending he was a doctor. Yesterday he proudly claimed in court that despite his complete lack of medical experience or qualifications, he had saved several people’s lives. He had even been allowed to assist a surgeon during an emergency operation on a patient who was about to die on something she had swallowed.
“I watched one of those TV dramas about a hospital and suddenly I felt like playing one of the roles myself. So I put on a white jacket and a stethoscope(听诊器)and walked around one of the biggest hospital in London. At first I just watched. Once you learn how doctors talk to patients, nurses and others doctors, it’s easy to take people in,” he said.
One of the patients he treated was Laura Kennan. She had been knocked down by a car and fainted. When she came to in hospital, York was standing over her.
“He looked very professional. He told me his name was Doctor Simon. Then he gave me some sort of injection,” she said. And then he suddenly cleared off when a nurse asked who he was. She didn’t think there was anything wrong. “I would never have realized he was a fake if a policewoman hadn’t showed me his photograph a week later. When the policewoman told me who he really was, I could hardly believe my ears.”
Judge Raymond Adams told York that he was “ shocked and horrified” that he got away with his deceiving for so long, and then sentenced him to eighteen months in a special prison for criminal with mental disorders.
“I can only hope that this will not lead to further problems. After all, you will have considerable opportunity to study the behaviour of the psychiatrists(精神科医生)who will look after you while you are there. If you try to persuade people that you yourself are a psychiatrist after you are set free, I shall make sure that you are given a much longer sentence.” Judge Adams warned York.
59. York was proud of the fact that ___________.
A. a surgeon let him watch an operation.
B. he could perform some duties of a doctor.
C. he had cheated doctors for so long
D. people thought he could become a real doctor
60. York learned how to behave like a doctor by __________.
A. watching other doctors work B. talking to doctors and nurses

61. Why was Laura Kennan in hospital?
A. She had swallowed something and almost died.
B. She had to have and emergency operation.
C. She had been injured in a road accident.
D. She had lost consciousness while driving.
62. The judge’s remark implied that York would be more severely punished if he _________.

The UN Environment Programme says that rising temperature could mean the end for some
migrating animals.Migrating or mobile animals move through several environments as they travel away from the cold of winter to warmer areas. Birds may fly from one part of the world to another, perhaps stopping at feeding grounds(聚食场) on the way. Whales and turtles cover vast areas of ocean. The report says that changes in any one of the places which these animals use can cause serious harm."Obviously these animals have developed their traveling patterns over thousands of years. But climate change is almost certain to be extreme over the next 25 t0 50 years, and it is extremely
unlikely that these animals can change their habits fast enough," said the report author Dr. Robert Hepworth.
Hardest hit by rising temperatures are turtles. Scientists have found that at higher temperatures,turtles produce far more female eggs than male ones. In parts of Malaysia, turtle birthing sites are producing only females, the report says, It also provides evidence that some turtles are more likely to develop cancer as the waters get warmer.
With birds, the main problem is climate-related damage to important areas at either end of the travels or at resting places along the way. About one-fifth of migrating birds are now in danger because of climate-related changes including rising sea levels, land loss and more violent storms,the report concludes.Other animals picked out as particularly in danger include:
◆the North Atlantic Right Whale, whose main food( tiny shrimp ) is disturbed by the change in ocean flows
◆the White-beaked Dolphin, which is out-competed by other kinds of dolphins in warmer waters.
The report is not all bad news. Even with major climatic changes, protecting the environment can still help mobile animals to recover.
"We need governments to start taking action at the national and international level. The clock is running." said Dr Hepworth. And some animals are already adapting, with the report mentioning whales that are changing their feeding behavior, finding new feeding grounds and new foods to eat.
48. What does the text mainly talk about?
A. The effect of climate change on migrating animals,
B. How animals are adapting to changes in temperature.
C. The importance of saving migrating animals.
D. The need for government policies to prevent global warming.
49. Which of the following is mentioned as a consequence of rising temperatures?
A. More storms will affect the ability of whales to find their feeding grounds.
B. 20% of all birds are likely to die out because of land loss.
C. Migrating animals can adapt to the changes quickly.
D. Warmer oceans will increase the competition between different kinds of dolphins.
