E
If you don’t have a college degree, you’re at greater risk of developing memory problems or even Alzheimer’s (老年癡呆).Education plays a key role in lifelong memory performance and risk for mental disorder, and it's well documented that those with a college degree possess a cognitive(認(rèn)知的) advantage over their less educated counterparts in middle and old age.
Now, a large national study from Brandeis University published in the American Journal of Geriatric Psychiatry shows that those with less schooling can significantly make up for poorer education by frequently engaging in mental exercises such as word games, puzzles, reading, and lectures.
“The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long,” said lead author Margie Lachman, a psychologist.She suggested that higher education may encourage lifelong interest in cognitive efforts, while those with less education may not engage as frequently in mental exercises that help keep the memory agile (敏捷地).
But education early in adulthood does not appear to be the only route to maintain your memory.The study found that intellectual activities undertaken regularly made a difference.“Among individuals with low education, those who are engaged in reading, writing, attending lectures, doing word games or puzzles once a week or more had memory scores similar to people with more education,” said Lachman.
The study, called Midlife in the United States, assessed 3,343 men and women between the ages of 32 and 84 with a mean age of 56 years.Almost 40 percent of the participants had at least a 4-year college degree.The researchers evaluated how the participants performed in two cognitive areas, verbal memory and executive function --- brain processes involved in planning, abstract thinking and cognitive flexibility.Participants were given a battery of tests, including tests of verbal fluency, word recall, and backward counting.
As expected, those with higher education said they engaged in cognitive activities more often and also did better on the memory tests, but some with lower education also did well, explained Lachman.
“The findings are promising because they suggest there may be ways to level the playing field for those with lower educational achievement, and protect those at greatest risk for memory declines,” said Lachman.“Although we can not rule out the possibility that those who have better memories are the ones who take on more activities, the evidence is consistent with cognitive plasticity (可塑性), and suggests some degree of personal control over cognitive functioning in adulthood by adopting an intellectually active lifestyle.”
57.What is the text mainly about?
A.Higher education has a better cognitive advantage.
B.Better memories result from college degree.
C.Cognitive activity does a mind good.
D.Poor education has more risk of memory declines.
58.According to the result of Margie Lachman’s study, we can conclude that ________.
A.education is responsible for the lifelong memory performance and risk for mental disorder
B.education early in adulthood can be the only route to maintain your memory
C.those with higher education did better on the memory tests than those with lower education
D.a(chǎn)n intellectually active lifestyle does help to maintain your memory
59.What do we know about the study called Midlife?
A.Participants each were given a battery to test their memory.
B.The average age of the participants are 56 years old.
C.Participants had to perform in one of the two cognitive areas.
D.One in four of the participants had a 4-year college degree.
60.Why are the findings of the Lachman’s study promising?
A.The lower educated may have the same opportunities to keep up memory.
B.We may have ways to cure the people who have memory declines.
C.Adopting a different lifestyle can control over cognitive functioning.
D.We can find out the possibility to have better memories.

Personal computers and the Internet give people new choices about how to spend their time.

Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience.

E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. My working hours aren’t necessarily much shorter than they once were but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she’d been born before electronic mail became such a practical tool.

The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun see a great movie perhaps-and there are four or five friends who might want to hear about it. If you call each one, you may tire of telling the story.

With E-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience.

E-mail is also an inexpensive way stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college.

We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don’t take the place of any of the old ways.

1.The purpose of this passage is to ________.

A.explain how to use the Internet

B.describe the writer’s joy of keeping up with the latest technology

C.tell the merits(價值) and usefulness of the Internet

D.introduce the reader to basic knowledge about personal computers and the Internet

2.The use of E-mail has made it possible for the writer to ________.

A.spend less time working

B.have more free time with his child

C.work at home on weekends

D.work at a speed comfortable to him

3.According to the writer, E-mail has an obvious advantage over the telephone because the former helps one ________.

A.reach a group of people at one time conveniently

B.keep one’s communication as personal as possible

C.pass on much more information than the later

D.get in touch with one’s friends faster than the later

4. The best title for this passage is ________.

A.Computer: New Technological Advances

科目:高中英語 來源:2013屆四川省成都市高二5月月考英語試卷(解析版) 題型:閱讀理解

When foreigners come to Chengdu, a good alternative is to get around by taking the bus. Once getting used to going by bus, you will discover that it is actually not that bad.

Although a ride usually covers two or twenty stops, a bus ride costs RMB 2 in Chengdu. It is important to carry enough small money with you, because it is not usual to get back changes. Even though it is cheap, you can pay less and save some trouble if you get a RMB 25 bus card at your local pharmacy, Hongqi Chain Store or bus station terminal office—note that personal identification is needed. Explain to the worker that you want to purchase a bus card.

With this card, one bus drive costs only RMB 1 if you use a card based on frequency of your ride. If your card is based on the so called E-purse, you pay each time RMB 1.80 for the bus. If you require the use of subway, you can ask the cashier at the Hongqi Chain Store to activate the metro. After having your bus card, you can store money on your travel card. The fees for bus and metro have to be stored separately.

It is important to keep in mind that the money on the card does not overlap. For example, you charge 40 bus rides on the card, but you only used 20 during the month, the rest 20 will be invalid at the beginning of the next month and you have to recharge the card. Therefore, it is important to calculate the exact numbers of bus rides you will have to take.

After you have your own bus card, one swipe is only needed when you get on the bus at the front door. If you only manage to get on the bus at the back door, just ask the passengers to pass your card to the front and swipe it for you. With the bus card, you can transfer buses for fee if the travel time is within two hours.

Furthermore, it is to stress that you should keep an eye on your belongings while being on the bus. Generally, Chengdu is a safe place but most of the thefts are occurring on buses, at train stations or crowded large area, like the shopping street Chunxi Road.

Due to the fact that the place names are announced in Chinese, it is better to know the Chinese name of your destination. Even though there are announcements in English, they will sound like the following: “The next stop is Jinjiang Binguan (Jinjiang Hotel)”

1.Which of the following statements is true when taking the bus in Chengdu?

A.It’s always important to carry enough small money with you every day.

B.It only costs RMB 25 to get around in Chengdu by bus per month.

C.Personal identification is not essential when applying for a bus card for locals.

D.RMB 0.2 will be saved each time if you use E-purse rather than cash on the bus.

2.Why are the readers reminded to pay close attention to their personal possessions?

A.Because Chengdu is not a safe place.

B.Because some thieves like stealing things in crowded buses.

C.Because people can transfer buses for fee within two hours.

D.Because the bus card must be swiped at the front door.

3.Why does the author suggest the Chinese name of the destination be learnt?

A.Because it helps know clearly where to get off the bus.

B.Because it can prevent people from missing the bus they want to board.

C.Because the place names are merely announced in Chinese.

D.Because it prevents the passengers getting off at the next stop on time.

4.The author might write this passage specially for ________.

A.The local Chengdu people who are interested in traveling by bus

B.Regular bus riders in Chengdu who fails to manage their bus cards properly.

C.New foreigners in Chengdu who want to get around by bus.

D.Pedestrians in Chengdu who are considering choosing to take the bus.
