Every year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict how, when, and where big storms will happen. The more exact scientists’ warnings are, the better people can prepare for the storms.
Predictions are improving. “We’re gotten better over the years, especially the last few years,” says Phil Klotzbach, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction. “For a hurricane to happen, conditions have to be just right, ” Klotzbach says.
First, the ocean water needs to be warm enough so that it evaporates and rises into the air. As it rises, the vapor(水蒸气)cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation of a hurricane.
If wind speeds reach 40 miles per hour, the system is called a “tropical storm”, and it gets a name. At 75 miles per hour, it becomes a hurricane.
Hurricanes that hit the US start when a thunderstorm forms off the coast of Africa. Storms also develop over tropical waters in other parts of the world.
On average, 60 or 70 storms form off Africa every year. About 10 of them get names. There are usually about six hurricanes. Two tend to be very big, with winds of 115 miles per hour or higher.
The hurricane season lasts from June to November. Ninety percent of all hurricanes hit in August, September, and October.

A gentleman put an advertisement in a newspaper for a boy to work in his office. Out of the nearly fifty men who came to apply, the man selected one and dismissed(解散) the others.
“I should like to know,” said a friend, “the reason you preferred that boy, who brough not a single letter—not a recommendation(介绍信).”
“You are wrong,” said the gentleman. He had a great many. He wiped his feet at the door and closed the door after him, indicating that he was careful. He gave his seat immediately to the crippled (跛的) old man, showing that he was kind and thoughtful. He took off his cap when he came in and answered my questions immediately, showing that he was polite and gentlemanly.
“All the rest stepped over the book which I had purposely put on the floor. He picked it up and placed it on the table; and he waited quietly for his turn instead of pushing and crowding.
When I talked to him, I noticed his tidy clothing, his neatly brushed hair, and his clean fingernails(指甲). Can’t you see that these things are excellent recommendations? I consider them more significant(明显的) than letters.”

Going to a Britain school for one year was a very enjoyable and exciting experience for me. I was very happy with the school hours in Britain  31  school starts around 9 a.m. and ends about 3.30 p.m. This means I could get up an hour  32  than usual as schools in China begin before 8 a.m.
On the first day, all students went to  33  assembly. I sat next to a girl whose name was Diane. We  34  became best friends. During  35 , the headmaster told us about the rules of the school. He also told us that the best way to  36  respect from the school was to work hard and  37  high grades. This sounded like my school in China.
My English improved a lot as I used English every day. I usually went to the Computer Club at lunch time, so I  38  e-mail my family and friends back home  39  free. I also had an extra French class on Tuesday evenings.  40  was really fun as I learned how to buy, prepare and cook food.

In England recently three foreign gentlemen came to a bus stop and waited. About five minutes later, the bus they wanted came along. They were just going to get on when suddenly there was a loud noise behind them. People rushed onto the bus and tried to push them out of the way. Someone shouted at them. The bus conductor came rushing down the stairs to see what all the trouble was about. The three foreigners seem all at sea and looked embarrassed. No one had told them about the British custom of lining up for a bus that the first person who arrives at the bus stop is the first person to get on the bus.
Learning the language of a country isn"t enough. If you want to have a pleasant visit, find out as much as possible about the manners and customs of your host country. You will probably be surprised just how different they can be from your own. A visitor to India would do well to remember that people there consider it impolite to use the left hand for passing food at table. The left hand is supposed to be used for washing yourself. Also in India, you might see a man shaking his head at another to show that he doesn"t agree. But in many parts of India a shake of the head means agreement. Nodding (点头) your head when you are given a drink in Bulgaria will most probably leave you thirsty.

In the southern part of America, when somebody has a birthday, often family or friends, or both, will arrange a party. The party could be elaborate(精心准备的)and include a meal or may be simple with a birthday cake and drinks. One does not plan, nor give, one’s own birthday as is the custom in some cultures. At a party there is usually a decorated cake, often with the words “Happy Birthday” and with the name of the person written on the top of the cake. Sometimes there is also one candle for each year of the person celebrating the birthday before the cake is cut. While blowing out the candles, the person makes a wish for something pleasant.
Usually those invited to a birthday party will bring a gift for the person honored. Gifts given by friends do not have to be expensive, but the family of the birthday person will spend whatever they can afford on a gift.
Christmas parties also are very popular in the South. Often this is the only time during the year that some people see acquaintances(熟人). These parties can be elaborate or simple, ranging from a buffet(自助餐)to a reception called “open house (家庭招待会)”. If you are invited to one of these, you don’t need to take a Christmas gift, as it is not customary to take the hostess a gift every time you are invited to a party or a meal. However, if you wish to take a gift, it should only be something useful and inexpensive and should be given to the hostess at the door as you enter the party. Usually gifts of Christmas food treats are the most appreciated.

The term “multitasking” originally referred to a computer"s ability to carry out several tasks at one time. For many people, multitasking has become a way of life and even a key to success. In fact, some excellent mental aerobic exercises (大脑训练) involve engaging the brain in two or more challenging activities at a time. Although checking e-mail while talking on a phone and reading the newspaper may be second nature for some people, many times multitasking can make us less productive, rather than more. And studies show that too much multitasking can lead to increased stress, anxiety and memory loss.
In order to multitask, the brain uses an area known as the prefrontal cortex (前额叶脑皮层). Brain scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if you"ve ever dialed (拨电话) a phone number and suddenly forgotten who you called when the line is answered. What probably occurred is that between the dialing and the answering, your mind shifted to another thought or task, and then took that “moment” to come back. Research has also shown that for many volunteers, job efficiency (效率) declines while multitasking, as compared to when they perform only one task at a time.
Multitasking is easiest when at least one of the tasks is habitual, or requires little thought. Most people don" t find it difficult to eat and read the newspaper at the same time. However, when two or more attention-requiring tasks are attempted at one time, people sometimes make mistakes.
We often don"t remember things as well when we"re trying to manage several details at the same time. Without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. That is one of the main reasons we forget people"s names—even sometimes right after they have introduced themselves. Multitasking can also affect our relationships. If someone checks their e-mail while on the phone with a friend, they may come off as absent-minded or disinterested. It can also cause that person to miss or overlook key information being passed on to them.
1. Why are some mental aerobic exercises designed to engage people in multitasking?
A. To make them more productive.                
B. To reduce their stress and anxiety.
C. To develop their communication Skills.         
D. To help them perform daily tasks more easily.
2. According to Paragraph 2, why may a person suddenly forget who he has called?
A. He may have his prefrontal cortex temporarily damaged.    
B. He is probably interrupted by another task.
C. He is probably not very familiar with the person he has called.    
D. He may need a rest between dialing and speaking.
3. People tend to make mistakes when       .
A. they perform several challenging tasks at a time 
B. new messages are processed one after another    
C. their relationships with others are affected       
D. the tasks require little thought
4. What is the main idea of the passage?
A. Multitasking has become a way of life.
B. Multitasking often leads to efficiency decline.
C. Multitasking exercises need to be improved.
D. Multitasking enables people to remember things better.
