17．Driving a car is not just handling controls and judging speed and distance．It requires you to predict what other road users will do and get ready to react to something unexpected，When alcohol is consumed，it enters your bloodstream and acts as a depressant （抑制药），damaging eyesight，judgment and co-ordination （协调），slowing down reaction time and greatly increasing the risk of accidents．Even below the drink driving link，driving well be affected．
Alc ohol may take a few minutes to be absorbed into the bloodstream and start action on the brain．Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice．To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee．
The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is：
●50 milligrams of alcohol per 100ml of blood；or
●22 micrograms of alcohol per 100ml of breath；or
●67 milligrams of alcohol per 100ml of urine（尿液）
Drivers who cause traffic accidents，or who commit a moving traffic offence or are being suspected of drink driving will be tested．
Any drive found drinking beyond the limit will be charged．The driver declared guilty may be fined a maximum of HK25，000 and be sentenced to up to 3 years in prison and punished for 10 driving-offence points； or temporarily banned from driving．
The same punishment applices to failing to provide speciments（本） far breath，blood or urine tests without good excuse．

14．Memory，they say，is a matter of practice and exercise．If you have the wish and really made a conscious（自觉的）effort，then you can quite easily improve your ability to remember things．But even if you are successful，there are times when your memory seems to play tricks on you．
Sometimes you remember things that really did not happen．One morning last week，for example，I got up and found that I had left the front door unlocked all night，yet I clearly remember locking it carefully the night before．
Memory"trick"work the other way as well．Once in a while you remember not doing something，and then find out that you did．One day last month，for example，I was sitting in a barber（理发师）shop waiting for my turn to get a haircut，and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office．
We always seem to find something funny and amusing（有趣的）in incidents caused by people's forgetfulness or absent-mindedness．Stories about absent-minded professors have been told for years，and we never got tired of hearing new ones．Unfortunately，however，absent-mindedness is not always funny．There are times when"trick"of our memory can cause us great trouble．

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.

Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic schooling Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person's thoughts.

In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

"Our brain has billions of nerve cells. These send signals through the spinal cord(脊髓)to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says. "Our system allows disabled people to communicate with external world and also to control devices."

The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair."

He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

1.BCI is a technology that can _________________.

A. help to update computer systems

B. link the human brain with computers

C. help the disabled to recover

D. control a person's thoughts

2.How did Tavella operate the wheelchair in the laboratory?

A. By controlling his muscles.

B. By talking to the machine.

C. By moving his hand.

D. By using his mind.

3.The team will test with real patients to .

A. make profits from them

B. prove the technology useful to them

C. make them live longer

D. learn about their physical condition

4.Which of the following would be the best title for the text?

A. Switzerland, the BCI Research Center

B. New Findings About How the Human Brain Works

C. BCI Could Mean More Freedom for the Disabled

D. Robotic Vehicles Could Help to Cure Brain Injuries

Today I went to Berkeley, near our old neighborhood. I was a bit surprised by the increased number of homeless (alternatively housed) people walking around. I remember there are more in certain areas. So the first man who asked me for money got all my single bills. So when the second man asked me two minutes later, I said I was out because I gave all I had to the previous person.

I was headed to the grocery store for a coffee and after I left the store I walked out to find him as he had asked me for something because he was hungry and I invited him to go into the grocery store with me.

When I asked him what he wanted to eat, he just asked for vegetable and rice. He talked about how much better the vegetables were as we waited for our number to be called. While we waited he told me that he had slept outside last night on the sidewalk, that it was not good, and that he had come from Rwanda and was alone.

He was a gentleman. When I asked if he wanted more he said, this bowl of food would last him the whole day.

I don’t know what his circumstances were before he came to California, and wandering and begging on the streets could somehow be better because you just never know what had happened to him. He seemed like a kind soul who just needed some help like we all do. I am grateful I did a little to help him today.

1.Why did the author fail to give the second homeless man money?

A. He kept some money for others. B. He spent all his money shopping.

C. He didn’t take any money that day. D. He donated all her small money to the first man.

2.What does the underlined word“ it” in Paragraph 3 refer to?

A. He was alone. B. He waited for his food.

C. He slept on the sidewalk. D. He was offered food.

3.How did the author feel about the homeless man?

A. Understandable. B. Pitiful.

C. Hopeless. D. Strange.

B vitamins（维生素）may offer some protection against the effect of air pollution,a new study suggests.

The scientists say the effect is real but stress the limitations of their work.Follow-up studies are urgently needed, they say,in heavily polluted cities like Mexico.

According to the World Health Organization (WHO),over 90% of the world's population live in heavily-polluted areas.The one of the pollutants that is considered the most dangerous is very fine particulate matter, referred to as PM2.5.At around 1/30 the width of a human hair,PM2.5 can go deep into the human lung and contribute to lung and heart health problems in the young and old.

Scientists have long suspected that PM2.5 causes what are termed epigenetic（表观遗传）changes in our cells that can damage our health.Now in this new human trial,an international team of scientists wanted to see if exposure to concentrations of PM2.5 could be mitigated by daily B vitamins.

Ten volunteers were tested initially exposed to clean air and their basic responses were measured.The same volunteers were later tested with large doses（剂量）of B vitamins while exposed to air containing high levels of PM2.5.The researchers found that a four-week B vitamin intake limited the PM2.5 effect by between 28-76% at ten gene locations.They found a similar reduction in effect on the mitochondrial DNA,the parts of cells that produce energy.

However,the researchers caution that their study,while observing a real effect,has limitations.As well as the small number of participants,there was little information on the size of the B vitamin dose that caused the response.

1.What is the main idea of the text?

A. B vitamins may fight against PM2.5.

B. PM2.5 can lead to epigenetic changes.

C. Further studies should be done on PM2.5.

D. Exposure to PM2.5 is more and more serious.

2.Which can replace the underlined word "mitigated" in Paragraph 4?

A. measured B. ignored

C. reduced D. observed

3.How many limitations does the text mention about the new study?

A. 2. B. 3.

C. 4. D. 5.

4.How does the writer of the text like the new study?

A. He believes it deeply. B. He criticizes it strongly.

C. He thinks it needs testing again. D. He shows no opinion about it.
