With time flying, people become aged. Then many people even in their middle age often start to notice that their memory and mental clarity are not what they used to be. We suddenly can’t remember 　　 　 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. As the brain 　　 　 , we refer to these occurrences as "senior moments". 　　 　　 seemingly innocent, this loss of mental focus can potentially have a(n) 　　 　　 effect on our　 social and　　 　　 　 well-being.

Neuroscientists,experts who study the nervous system, are increasingly showing that there’s actually a lot that can be done. It 　　 　　 out that the brain needs exercise in much the same way our muscles do, and the right mental 　　 　 can significantly improve our basic cognitive(认知) 　　 　　 . Thinking is basically a 　　 　　 of making connections in the brain. To a certain extent, our ability to　　 　　 　 in making the connections that drive intelligence is inherited(继承). 　 　　 　 　 , because these connections are made through effort and practice, scientists believe that intelligence can expand and wave 　　 　 mental effort.

Now, a new Web-based company has taken a step　　 　　 　　 and developed the first "brain training program" designed to actually help people improve and 　 　　 　 their mental sharpness.

The Web-based program　 　　 　 you to systematically improve your memory and attention skills. The program keeps a(n) 　　 　　 of your progress and provides detailed feedback(反馈) 　　 　　 your performance and improvement. Most importantly, it　 　　 　 　 changes and improves the games you play to　 　　 　　 up the strengths you are developing-much like a(n) 　　 　　 exercise routine which requires you to increase resistance and vary your muscle use.

Twenty minutes isn't even enough time to catch a lecture of The Big Bang Theory. Yet for many people, that’s the amount of face time they'll get with their doctors all year. 1. During the time, try to ask the confusing questions, which is the key to staying healthy in between checkups.

What happens if I don't take the medicine?

Many patients feel medicine should be taken when they're obviously sick, and skip it when they feel they have recovered. But some conditions take months or even years to be completely removed. In such case, even if you don't have symptoms, don't skip medicine. 2.

Does the medicine interact with my supplements (增补物)?

Many patients assume that supplements like vitamins or herbs are helpful and won't interact with their medicine. That's a dangerous assumption. There're many drug interactions with herbs and nutrients. 3.Patients on certain antidepressants (抗抑郁剂), for example, should not take herbs like St. John's wort (圣约翰麦汁).

What changes can I make to improve my condition?

Diet, exercise, sleep, and stress are all huge elements that impact health and are all completely under a patient's control. 4. But in almost every case, your health can be improved with changes to those four elements.

5.

Your treatment can be a journey, and you should know what kinds of signposts (路标) to look for-good and bad. Being aware of potential challenges, side effects, and failure rates can help you prepare for issues and important improvements: you and your doctor can come up with ways to deal with both.

A. And some can be deadly.

B. Why should I have to deal with the health issues?

C. In many cases, drugs and medicine may be necessary.

D. What kind of improvements and problems should I expect?

E. Instead, take it regularly so that it can have its intended effect.

F. In your next checkup, instead, be prepared for the twenty minutes.

G. That's why it makes sense to make full use of that precious period.

Feelingsoftenrun high where insects are concerned,with many people even sick when seeing them, let alone touch or swallow them.And yet insects present a huge nutritional opportunity as an increasing globalpopulation seeks more sources of food and feed.

Insects have generally high levels of animal protein and key micronutrients with lower environmentalfootprints than traditional alternatives,and they can be raised on leftovers.But cultural,social and economicproblems remain,reports an article published today in Nutrition Bulletin.

“Insects present a nutritional opportunity,but it is unclear how their nutritional quality is influenced bywhat they are fed,”says Darja Dobermann,a researcher at the University of Nottingham.“In idealconditions,insects have a smaller environmental impact than most traditional western forms of animal protein; less known is how to raise insect production while maintaining these environmental benefits.”

“Studies overall show that insects could make valuable economic and nutritional contributions to the foodor feed systems,but there are no clear regulations in place to bring insects into such supply systems withoutthem turning into a more expensive version of poultry（家禽）for food,” says Dobermann.

The article highlights how insects have been a source of food for hundreds of years in more than 100countries with over 2,000 species that can be eaten; in central Africa,up to 50% of dietary protein has comefrom insects,with their market value higher than many alternative sources of animal protein.

Insects need to be large enough to make the effort of catching them worthwhile and easy to locate,preferably in predictably large quantities.They are consumed at various life stages,as raw,fried,boiled, roasted or ground food.

1.Which of the following is the advantage of raising insects for food?

A. It will offer people work opportunities.

B. It is environmentally friendly.

C. It will replace traditional food.

D. It will result in less leftovers

2.What can be inferred from Dobermann’s words?

A. Raising insects for food has become popular.

B. Raising insects can’t solve food problems.

C. More should be done to raise insects for food.

D. More money can be made by raising insects.

3.What does the underlined word in paragraph 4 stand for?

A. Insects. B. Regulations.

C. Feed systems. D. Supply systems.

4.Which is the possible title of this passage?

A. How to Raise Insects B. Raising Insects for Money

C. Insects Seem No Longer Ugly D. A New Source of Food

The flying car has been talked about for many years, but now it appears to become a reality.

An international company has built a two-seater plane that, at the touch of a button, transforms into a car perfectly suitable for driving on public roads. It takes 15 seconds to switch between flying and driving. With its wings fully open and the propeller(螺旋桨) spinning, it can take off from any airfield.

Flying cars are quicker than traditional ones, and they can run on ordinary fuel. Another big advantage is that they are cool, like something you would see in an action film. At the moment, however, the flying car’s wheels are illegal to leave the ground. That is not because of technical reasons or problems with the design. It is because the various road and aircraft authorities simply cannot agree on whether it is a car or a plane.

Nevertheless the company hopes to produce and deliver its first flying car soon. The company already has orders for 40 of them. The majority potential customers are older and some are retired. There have even been orders from some people who have no pilot’s license.

The flying car will cost around $ 200,000. “For an airplane, that’s a very reasonable price, but for a car, it’s quite expensive,” explains Alan. “But it just is not possible to make a $ 10,000 flying car yet.”

This latest means of transport will not become a mass-market item in the near future, but in the long term it has the potential to change the way you travel. It will become no more expensive than driving your car on the motorway. Travel time could be reduced by more than half.

So the next time you are told to fasten your seat belt, it may be to prepare for take-off.

1.We know from the passage that the flying car 　　　　 .

A. has to run on special fuel

B. will replace traditional planes

C. is popular with the rich

D. can shift between two forms

2.The flying car is presently forbidden to take off because 　　　　 .

A. many people think driving is not very safe

B. it’s hard to decide whether it’s a car or a plane

D. there are still some technical problems to be solved

3.According to the passage, we can learn 　　　　 .

A. in the future few people will be able to afford a flying ear

B. owning two kinds of driving licenses is of great importance

C. because of the appearance of the flying car, traffic jams will disappear

D. flying cars may share the market in the future

4.What’s the best title of the passage?

A. Your Car Is Ready for Take-off

B. Flying Car Will Be the Leading Means of Transportation

C. Affording a Flying Car Is a Necessity

D. The Advantages of Flying Cars

In recent years, many Americans of both sexes and various ages have become interested in improving their bodies. They have become devoted to physical fitness. The need to exercise has almost become natural with many people who have a strong desire to be more physically fit.

By nature, Americans are enthusiastic and energetic about their hobbies and pastimes. They apply their energy to running. As a result, there are running clubs to join and many books and magazines to read about running.

The desire to be physically fit is explained by a “passion” for good health. The high rate of heart attacks in the 1960s caused an increase on the part of the public in improving the human body. Middle-aged men especially suffered from heart attacks. Thus, they are one group strongly interested in more physical exercise. In fact, many doctors encourage their patients to become more physically active, especially those who have sedentary jobs. It is interesting to note that the rate of heart attacks began to decrease in the 1970s and it is still decreasing. Physical fitness enjoys a favored role in the United States at present. It is a new “love” that Americans have valued very much. Will it last long? Only time will tell--- or until another “new passion” comes along.

1.We can learn from the passage that ________ .

A. people’s interest in physical exercise has something to do with their health condition

B. by nature, Americans are stronger and more energetic than others

C. the love for physical exercise won’t last long in American

D. men have a stronger desire than women to take exercise

2.In recent years, many Americans have become interested in improving their bodies because ________ .

A. there are many running clubs to join

B. they are eager for their hobbies and pastimes

C. they have a strong desire to be more physically fit

D. there are many books and magazines about running

As motorways become more and more blocked up with traffic, a new generation on flying cars will be needed to ferry people along skyways. That is the conclusion of engineers from the US space agency and aeronautical firms, who envision future commuters traveling by “skycar”.

These could look much like the concept skycar shown in the picture, designed by Boeing research and development. However, such vehicles could be some 25 years from appearing on the market. Efforts to build flying vehicles in the past have not been very successful. Such vehicles would not only be expensive and require the skills of a trained pilot to fly, but there are significant engineering challenges involved in developing them. “When you try to combine them you get the worst of both worlds: a very heavy, slow, expensive vehicle that’s hard to use,” said Mark Moore, head of the personal air vehicle(PAV) division of the vehicle systems program at Nasa’s Langley Research Center in Hampton, US. But Boeing is also considering how to police the airways-and prevent total pandemonium(吵杂狂乱的喧闹)-if thousands of flying cars enter the skies.

“The neat, gee-whiz part is thinking about what the vehicle itself would look like,” said Dick Paul, a vice president with Phantom Works, Boeing’s research and development arm. “But we’re trying to think through all the consequences of what it would take to deploy(散开) a fleet of these.”

Past proposals to solve this problem have included artificial intelligence systems to prevent collisions between air traffic. Nasa is working on flying vehicles with the initial goal of transforming small plane travel. Small planes are generally costly, loud, and require months of training and lots of money to operate, making flying to work impractical for most people. But within five years, Nasa researchers hope to develop technology for a small plane that can fly out of regional airports, costs less than $100,000(£55,725), is as quiet as a motorcycle and as simple to operate as a car.

Although it would not have any road-driving capabilities, it would bring this form of travel within the grasp of a wider section of people. The new technology would automate many of the pilot’s functions. This Small Aircraft Transportation System(Sats) would divert pressure away from the “hub-and-spoke(中心辐射型)” model of air travel. Hub-and-spoke refers to the typically US model of passengers being processed through large “hub” airports and then on to secondary flights to “spoke” airports near their final destinations.

1.The best title for this text would be ________.

2. The underlined word “envision” in Paragraph 1 most probably means “________”.

3.When engineers develop the skycars, they have to deal with the following difficulties except ________.

4. Now Nasa researchers’ aim is to ________.
