People with mentally taxing jobs, including lawyers and graphic designers, may end up having better memory in old age, research suggests.

A study of more than 1,000 Scottish 70-year-olds found that those who had had complex jobs scored better on memory and thinking tests.

One theory is that a more stimulating environment helps build up a “cognitive reserve” to help buffer the brain against age-related decline. The research was reported in Neurology.

The team, from Heriot-Watt University, in Edinburgh, is now planning more work to look at how lifestyle and work interact to affect memory loss. Those taking part in the study took tests designed to assess memory, processing speed and general thinking ability, as well as filling in a questionnaire about their working life.

The analysis showed that those whose jobs had required complex skills in dealing with data or people, such as management and teaching, had better scores on memory and thinking tests than those who had done less mentally intense jobs such as factory workers, bookbinders, or carpet layers.

While the study did not look at biological reasons for the protective effect of certain jobs, potential explanations include that structural changes within the brain mean less damage is accumulated over time.

Study leader Dr Alan Gow said: “Our findings have helped to identify the kinds of job demands that preserve memory and thinking later on.” “However,” He added, “while it is true that people who have higher cognitive abilities are more likely to get more complex jobs, there still seems to be a small advantage gained from these complex jobs for later thinking skills.”

Dr Simon Ridley, head of research at Alzheimer’s Research UK, said the study added to the growing evidence about factors that affected brain health as we aged.

“Keeping the brain active throughout life could be helpful and different types of work may play a role. However, it’s important to note that this study points to a small and subtle association between occupation and later-life cognition rather than offering proof that people’s occupation has a direct influence.”

1. According to the research, who may have the best memory in old age?

A. Taxi drivers. B. Computer programmers.

C. Supermarket cashiers. D. Motor mechanics.

2. Which of the following about the research work is TRUE?

A. The research team studied both environmental and biological factors.

B. The researchers filled in a questionnaire about their working life.

C. The research objects included people from various jobs and of different ages.

D. The research is helpful to the study of brain health and is still under way.

3. What Dr Alan Gow said implies that __________.

A. their findings are helpful to identifying the kinds of job demands

B. people who do more complex jobs may benefit later thinking skills greatly

C. there exist links between job demands and preservation of memory

D. he didn’t confirm the links between complex jobs and later thinking skills

4.We can learn from Dr Simon Ridley that __________.

A. different occupations may make a difference in keeping the brain active

B. people’s occupation has a direct influence on later-life cognition

C. the study added more evidence about the factors affecting aging

D. the study denied the association between jobs and later-life memory

Paparazzi, or “paps”, are photographers who take pictures of famous people when they are not at the center of public attention. Paps are different from professional photographers or journalists because they never take ordinary photos.

The goal for paparazzi is to get pictures that no one else will get and then sell the pictures to the buyer who offers the most money — normally a small newspaper, magazine or website.

There is no law against paparazzi taking pictures in public places. However, there are laws that protect certain individuals. For example, child protection laws stop improper pictures of anyone under 16 from being published.

There is also no law that stops paparazzi from following celebrities and taking their pictures either. However, if paps are secretly following them and taking pictures of their faces, they could get into trouble.

Most paparazzi hang out on streets and hot spots for celebrities, waiting for the opportunity to take a picture of a star. Many stay on the streets until the early hours of the morning when celebrities are leaving nightclubs and looking a little worse for wear. However, some have other ways to make sure they get pictures. Many paps are in contact with “informers” who know the locations of celebrities at any given time. They then pass the information on to paparazzi. An informer could be anyone — from a restaurant waiter to a salesman.

Most of the time, paparazzi get a bad reputation for following celebrities. But sometimes stars or their managers will contact paps themselves and tell them exactly where and when they will go. What a love-hate relationship between paparazzi and celebrities!

1.Which of the following things paparazzi might do would be against the law?

A. how paparazzi get the pictures

A. Paparazzi always take pictures when famous people are tired.

B. Stars hate paparazzi and don’t want to be followed.

C. Paparazzi and famous people rely on each other sometimes.

D. Informers might get paparazzi into trouble.

I take the firm position that parents do not owe their children a college education. If they can it, they will certainly send them to the best universities. But they need not feel if they can’t. If the children really want to go, they’ll find a . There are plenty of loans and scholarships for the bright and ones who can’t afford to pay.

When children grow up and want to , their parents do not owe them a down payment on a house. They do not have the to baby-sit their grandchildren. If they want to do it, it must be considered a not an obligation (责任,义务).

Do parents owe their children anything? Yes, they owe them a great deal.

One of their obligations is to give their children a personal . A child who is constantly made to feel stupid and unworthy, constantly to brighter brothers, sisters, or cousins will become so , so afraid of failing that he (or she) won’t try at all. Of course they should be corrected when they do wrong, but it’s often better to let children learn their mistakes by themselves . All our parents should do is to trust them, respect them, tolerate (宽容) them and give them chances to try and fail. They must learn to stand . When criticisms (批评) are really needed, they should be with praises, with a smile and a kiss. That is the way children learn.

Parents owe their children a set of solid values around to build their lives. This means teaching them to the rights and opinions of others; it means being respectful to elders, to teachers, and to the law. The best way to teach such values is by deed and ________. A child who is lied to will . A child who sees no laughter and no love in the home will have difficulty laughing and loving.

No child asks to be . If you bring a life into the world, you owe the child .

How many times a day do you check your email? When you wake up? Before bed? A dozen times in between? The technology that was supposed to simplify our lives has become the vital time-suck: the average teen spends more than seven hours a day using technological devices, plus an additional hour just text-messaging friends.

The advantage of technological devices is connectedness: email lets us respond on the go, and we are in touch with more people during more hours of the day than at any other time in history. But is it possible we’re more lonely than ever, too? That’s what MIT professor Sherry Turkle observes in her new book, Alone Together, a fascinating portrait of our changing relationship with technology. Turkle details the ways technology has redefined our comprehension of closeness and loneliness—and warns us of the danger of accepting such virtual(虚拟的) relationships in place of lasting emotional connections.

For Turkle, the biggest worry is the effect all these shallow connections have on our development. Is technology offering us the lives we want to live? “We’re texting people at a distance,” says Turkle, “We’re using lifeless objects to convince ourselves that even when we’re alone, we feel together. And then when we’re with each other, we put ourselves in situations where we are alone—constantly on our mobile devices. It’s what I call a perfect storm of confusion about what’s important in our human connections.”

What can’t be denied is that technology, whatever its faults, makes life a whole lot easier. It allows us to communicate with more people in less time and makes conversation simple. But it can also be seductive(具有诱惑性的), providing more stimulation than our natural lives. There are usually some unhealthy videos online which remove teenagers’ attention from their schoolwork. Besides, some online activities make people addicted, which occupied their daily life and affected their ability to form real-world relationships.“Technology can be more immediately satisfying than the labor of building an intimate relationship,” said one highschool student, “Every time I text, I start to have some happy feelings.”

But are any of those feelings equal to the kind we feel when engaged in real, face-to-face communication? Online, you can neglect others’ feelings. In a text message, you can avoid eye contact. A number of studies have found that this generation of teens is less sympathetic than ever. That doesn’t spell disaster, says Turkle—but,
