小学生10分钟应用题系列答案People have smoked cigarettes for a long time now. The tobacc
o which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe . In the late 1800s, the Turks made cigarettes popular.
Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco burns, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person’s breathing muscles. Smokers usually take in small amounts that the body can quickly break down.
Nicotine can make new smokers feel dizzy(头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers’ risk of heart disease and stroke.
Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.

-What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live, Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

Most people around the world are right-handed . This also seems to be true in history . In 1799 , scientists studied works of art made at different times from 1,500 B.C. to the 1950s . Most of the people shown in these works are right-handed , so the scientists guessed that right-handedness has always been common through history . Today , only about 10% to 15% of the world’s population is left-handed .
Why are there more right-handed people than left-handed ones ? Scientists now know that a person’s two hands each have their own jobs . For most people , the left hand is used to find things or hold things . The right hand is used to work with things. This is because of the different work of the two sides of the brain . The right side of the brain , which makes a person’s hands and eyes work together , controls the left person’s hands and eyes work together , controls the left hand . The left-side of the brain , which controls the right hand , is the centre for thinking and doing problems . These findings show that more artists should be left-handed , and studies have found that left-handedness is twice as common among artists as among people in other jobs .
No one really knows what makes a person become right-handed instead of left-handed . Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born . However , this doesn’t happen to everyone , so scientists guess there must be another reason why people become left-handed . One idea is that people usually get right-handed from their parents . If a person does not receive the gene（基因）for right-handedness , he / she may become either right-handed or left-handed according to the chance and the people they work or live with .
Though right-handedness is more common than left-handedness , people no longer think left-handed people are strange or unusual . A long time ago , left-handed children were made to use their right hands like other children , but today they don’t have to .
【小题1】 After studying works of art made at different times in history , the scientists found .
A. art began from 1, 500 B.C.
B. the works of are ended in the 1950s
C. most people shown in the works of art are right-handed
D. most people shown in the works of art are left-handed
【小题2】How many people in the world are left-handed now ?
| A．Less than one sixth . | B．More than a half . |
| C．About 40% . | D．The passage doesn’t tell us . |
| A．It’s used to find or hold things . |
| B．It’s used to work with things . |
| C．It’s used to make a person’s eyes work together . |
| D．It’s the centre for thinking and doing problems . |
| A．No one really knows what makes a person become right-handed . |
| B．Left-handedness is cleverer than right-handedness . |
| C．Today children are not made to use their right hands only . |
| D．Scientists think there must be some reason why people become left-handed . |
| A．Scientist’s New Inventions |
| B．Left-handed People |
| C．Which Hand |
| D．Different Brains , Different Hands |
Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut.” Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up (蜷伏)with me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what’s on their minds. “In fact, parents are first on the list.” said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.
