Some kinds of mental skills naturally decrease as people get older. Yet research seems to show that some training can improve such skills. A recently published study also appears to attest that the good effects of training can last for many years after that training has ended.

Researchers at Johns Hopkins University in Maryland wanted to learn how long memory and thinking skills would last in older people who were trained to keep them. The people were part of the ten-year research project. They were taught methods meant to improve their memory, thinking and ability to perform everyday tasks.

More than 2,800 volunteered for the study called ACTIVE — short for Advanced Cognitive Training for Independent and Vital Elderly. Most were studied when they were more than 70 years old.

The volunteers took one of several short training classes meant to help them keep their mental abilities. One class trained participants in skills including how to remember word lists. Another group trained in reasoning. A third group received help with speed-of-processing — speed of receiving and understanding information. A fourth group — the control group did not get any training.

Earlier results had established that the training helped the participants for up to five years. Now, leading study writer George Rebok says, the research showed most of the training remained effective a full ten years later.

Professor Rebok and his team found that the people trained in reasoning and speed-of- processing did better on tests than the control group.

“We are wondering whether those effects which endured over time would still be there ten years following the training, and in fact, that's exactly what we found.,,

The effect on memory, however, seemed not to last as long. Still, the old people in any of the three classes generally reported less difficulty in performing daily activities than the control group.The total training time for the older people was between 10 and 15 hours.

1. Which statement is false according to the text?

A. This kind of training can only have effects on people for a few years.

B. The people were trained during a period of ten years.

C. Most of the people who were studied were more than 70 years old.

D. The first group were trained how to remember word lists.

2. How would the old in the second group perform after receiving the trauung?

A. Remember more words.

B. Understand information more quickly.

C. Act as poorly as before.

D. Perform daily activities better.

3. What does the underlined word "attest" in the first paragraph mean7

A-Affect. B. Deny.

C. Prove. D. Improve.

4. Which of the following can be the best title for the passage?

A. Some Kinds of Mental Skills Naturally Decrease.

B. Mental Training Helped Elderly Stay Sharp for Years.

C. Four Groups of Old People Were Trained Mentally.

D. A Ten-year Research Affects Elderly.

The attraction of television is undeniable when it comes to kids. 1. Here are guidelines we created to help us decide what’s appropriate for our family:

Monitor television time. Choosing good shows isn’t a big issue if you’re not watching a lot of television, so really the best solution to finding appropriate television is saying, “Go play.” 2.

Don’t trust network ratings. A kid-approved stamp given by a television network is a general guide that doesn’t take into account your parenting style and the things your family feels are important. 3. There are plenty of adult cartoon shows on television now, many with highly inappropriate topics.

4. The bottom line is, I want to know what my kids are watching, and if the TV is on my time in our home, I want to first approve of the show ahead of time, and second to watch it with my kids so that I’m aware of anything they might be seeing that needs intervention(干涉).

Talk about the show with your kids. As kids get older, we realize that we can’t shelter them from every single person/show/behavior that doesn’t fit exactly with our values. They’re going to hear a swear word from time to time—and might walk into the room while the characters in the romantic comedy we’re watching are kissing. 5.

A. If it doesn’t feel good, turn it off.

B. And be aware of cartoons!

C. We can talk about what we see, though, using story-lines to teach lessons when possible.

D. The standard for what our kids can watch might be difficult to set.

E. But how do you choose which shows are appropriate for the younger set?

F. Watch TV with them.

G. Still, a little bit of television doesn’t hurt and can be fun.

Around the world, honeybee groups are dying in huge numbers: About one-third of nests collapse each year. For bees and the plants they pollinate (授粉) — as well as for beekeepers, farmers, honey lovers and everyone else who appreciates this marvelous social insect — this is a catastrophe.

Honeybee collapse has been particularly worrying because there is no one cause, but rather a thousand little cuts. The main elements include the mixed impact of pesticides (杀虫剂) applied to fields, as well as pesticides applied directly into nets to control bugs, pests and diseases; nutritional shortages caused by vast acreages of single-crop fields that lack diverse flowering plants; and commercial beekeeping itself, which destroys groups by moving most bees around the country multiple times each year to pollinate crops.

The real issue, though, is not the volume of problems, but the interactions among them. Here we find a major lesson from the bees that we ignore at our risk: the concept of synergy (协同作用), where one plus one equals three, or four, or more. A typical honeybee colony contains remains from more than 120 pesticides. Alone, each represents a benign dose (良性剂量). But together they form a poisonous soup of chemicals whose interplay (相互作用) can greatly reduce the effectiveness of bees’ immune systems, making them easier to suffer from diseases.

Observing the death of honeybees should warn us that our own well-being might be similarly threatened, and the widespread collapse of so many groups presents a clear message: We must demand that our regulatory authorities require studies on how exposure to low dosages of combined chemicals may affect human health before approving compounds.

Bees also provide some clues to how we may build a more collaborative relationship with the services that ecosystems can provide. Bees could offer some of the pollination service needed for agriculture. People discovered that crop harvests, and thus profits, are maximized if some cropland are left uncultivated for bees. Meanwhile a variety of wild plants means a healthier, more diverse bee population, which will then move to the planted fields next door in larger and more active numbers.

1.Which of the following is NOT the cause that leads to bees dying?

A. Lack of nutrition from enough diverse flowering plants.

B. The pests and diseases of the bees.

C. The beekeepers’ destroying without intention

D. The pesticides applied to crops.

2.By saying “one plus one equals three, or four, or more” in Paragraph 3, the author means that ____.

A. bees united mean they are much more powerful

B. bees united mean they are much more poisonous

C. pesticides mixed mean they are much more poisonous.

D. pesticides mixed mean they are much more effective.

3.The lesson people can learn from bees dying is that ____________.

A. medicine is as powerful as pesticide

B. our health might be threatened by pesticides

C. we should protect bees by reducing the usage of pesticides

D. medicine may be harmful to us when used together

4.What is the last paragraph mainly about?

A. Keeping a balance with nature is important

B. More plants mean more and healthier bees.

C. Bees are very important to agriculture.

D. Bees can bring in good higher profits to farmers

Dear Grandpa,

How are you those days? I have been missing you very much after I went to college a year ago. Whenever I think of the old days, I feel very happily. I still remember when I was child, you always held me in your arms and told me stories till I fall asleep. We often went to the fields to enjoy the pleasant view there. You told me the name of different plants and their characteristics. Gradually, I became interesting in biology and chose to learn biology when I entered into the college. Now my friend Ann, together with me, are going to do field study and the findings will be use as materials for our research. Since we’ll do the study in our hometown, I hope to see you by then.

Yours,

Daisy
