It has been discovered that after the age of ...

It has been discovered that after the age of sixteen, the number of our brain cells begins to decrease at a speed of several million a year. They simply die off. In certain types of activity, the human brain is at its highest point in the early twenties, when it has collected enough information to be able to use the vast number of cells freely in the most effective way. Pure mathematics is one of the fields in which this happens, and we know that Albert Einstein made all his world-shaking discoveries between the age of about 20 and 25, and spent the rest of his life tidying them up and arranging them.

But in certain other types of activity (of which being an author is perhaps one), experience is more important than sharpness of brain, and there one usually finds that a person reaches his or her peak much later in life.

Besides sharpness of brain and experience, here is another thing that is very important, and that is wisdom. One can have a very quick, inventive brain and plenty of experience, but if one uses these foolishly, one harms both oneself and others. Wisdom does not always come with age ——there are plenty of foolish middle-aged people about ——but the average person tends to learn wisdom as he gets older, usually by making painful of embarrassing mistakes. Leaning to be wise is basically learning what is not possible ； and what is possible but so difficult that it is not worth all the trouble one has to go through to get there. Mostly, it is learning about human nature ； how real people behave and react, as against how one would like them to behave and react. One can read and hear lot of idealistic stuff about how to make the world a better place, which would be found if it was based on an accurate observation of human nature, but which is basically a waste of time because it is not.

1.According to the writer, the great discoveries made by Albert Einstein were mainly a result in　　　 .

A.years of hard work B.sharpness of the brain

C.rich experience D.his deep understanding of the nature

2.Some people achieve success much later in life because .

A.their work often requires much experience

B.they do not have a chance to show their talents

C.they have to learn lessons from failures

D.they fail to realize earlier the importance of hard work

3.The importance of wisdom lies in the fact that .

A.it helps to avoid various mistakes

B.it contributes to one's creativity

C.it encourages one to go forward in face of difficulty

D.it provides the right direction of efforts

4.The writer came to believe that .

A.it is always a waste of time to make plans about the future

B.it is human nature to make attempts on what looks impossible

C.one should always challenge the impossible to push the society forward

D.one has to use wisdom in deciding what is the best thing to do

I guess she meant that if you’re middle aged and don’t have a car then you are a loser. How arrogant (傲慢) and ignorant！

Unfortunately, there are still people who think that way: that somehow public transport is only for the poor. And the rest have a right to their cars. Some wealthy folk in the West look down on buses and boast (吹嘘) about how many years it has been since they last traveled by one.

How sad is that? Our roads are packed with cars and the air is full of the pollution they emit (排放). But still, many car users are unwillingly to get on a bus or a bike or a train to take themselves to work.

It’s convenient to drive, they’ll say. Buses are so unreliable, they’ll claim. And trains are expensive ---- at least in the UK.

It’s an attitude which may have to change. It doesn’t make sense to drive a car in a city where there’s a public transport system. Also, these rush hour commuters (往返上班者) usually travel alone.

As a result, transport authorities in the UK are looking at solutions to city center congestion (拥堵).

One is to increase the number of parking spaces at out-of-town railway stations. More motorists (乘汽车的人) can then leave their cars and travel into the city by train.

Light rail or tramways are another environmentally friendly solution. Many cities across Europe have installed light rail or tramway systems.

The subway in London is used by everyone, rich and poor. It’s the quickest way of getting around the city, whatever your bank balance.

And then there are the cycle hire schemes you find in many modern cities. In London and Paris, you can hire a bike by the hour to get you where you need to go.

While commuters in Beijing abandon their bicycles for cars, cycling to work grows in popularity in the West.

Many cyclists are willing to pay more than 10,000 yuan for their bicycles. Mayor of London, Boris Johnson, is often pictured cycling to work. David Cameron, the British prime minister, cycled to the House of Commons before he became leader. These days he takes the prime ministerial limousine (豪华轿车).

1.. According to the article, some British people, like the upper class woman, think that ________.

A. buses are inconvenient                B. bus services are unnecessary

C. having a car is a sign of success         D. only the upper class should have cars

2. Which of the following measures is taken by transport authorities in the UK to solve city center congestion?

A. The development of cycle hire schemes.

B. Increasing the number of parking spaces in the city center.

C. Installing light rail or tramway systems in out-of-town areas.

D. Banning commuters from traveling alone during rush hour.

3.The author mentions the example of Boris Johnson in the last paragraph to ________.

A. express his respect for the mayor of London

B. point to the growing popularity of cycling to work in the West

C. criticize Beijing commuters for abandoning their bicycles for cars

D. show that cars are still the most common means of transportation for famous people in Britain

4. Which of the following might the writer agree with?

A. The British prime minister should give up his limousine.

B. Beijing commuters should learn from British commuters.

C. British solutions to public transport problems are inadequate.

D. Many car owners need to change their attitudes if the traffic problem is to

高三英语简单题查看答案及解析

SCIENTISTS have discovered that living to the age of 100 may have nothing to do with the lifestyle you lead and everything to do with the type of genes (基因) you have.

For the lucky carriers of “Methuselah” genes, worries over smoking, eating unhealthily and not getting enough exercise may not be as necessary as to those of us without the special gene pattern .

The “Methuselah” genes could give extra protection against the diseases of old age such as cancer and heart disease. They could also protect people against the effects of the unhealthy lifestyles that we believe will lead us to an early death, scientists say. However, the genes are very rare.

The genes include ADIPOQ, which is found in about 10 percent of young people but in nearly 30 percent of people living past 100. They also include the CETP and the ApoC3 genes, which are found in 10 percent of young people, but in about 20 percent of people over 100 years old.

Some of those genes were discovered by a research group at the Albert Einstein College of Medicine in New York, led by Professor Nir Barzilai. The team studied the genes of over 500 people over 100 years old, and their children.

The studies show that tiny mutations (变异) in the make-up of some genes can greatly increase a person’s lifespan. Barzilai told a Royal Society conference that the discovery of such genes gave scientists clear targets for developing drugs that could prevent age-related diseases, allow people to live longer and stay healthy.

David Gems, a researcher at University College London, believes that drugs to slow ageing will become widespread.

“If we know which genes control longevity (长寿) then we can … target them with drugs. That makes it possible to slow down ageing,” he told The Times.

“Much of the pain and suffering in the world are caused by ageing. If we can find a way to reduce that, then we are obliged to take it.”

1. According to the article, which of the following is the most important if a person is to live to the age of 100?

A. Eating healthy food every day.

B. Having the right types of genes.

C. Having a healthy lifestyle.

D. Taking drugs that prevent ageing.

2.According to the article, the ApoC3 gene is found in ______ of people over 100 years old.

A. 10%           B. 20%          C. 30%       D. 50%

3.Which of the following statements is TRUE of the research led by Professor Nir Barzilai?

A. The team studied the genes of over 100 people over 100 years of age.

B. The researchers found that mutations in certain genes lead to longer life.

C. The researchers found ways to develop drugs that could cure age-related diseases.

D. The study suggested that most people have genes that could lengthen their lives.

4. According to David Gems, ______.

A. drugs to slow ageing will be very expensive

B. modern science will be able to find more longevity genes

C. it is the duty of medical scientists to fight the problems of ageing

D. scientists can make new genes that will allow longer life
