Doctors are starting to worry that younger and younger students are having back and neck problems as a result of schools bags being too heavy for them.
"It’s hard for me to go upstairs with my bag because it’s so heavy, "said Rick Hammond, an 11-year-old student in the US.
Rick is among students who have common school bags with two straps(带子) to carry them, but many other students choose rolling(有滚轮的)bags.
But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.
But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight(重量).
Scott Bautch, a back doctor, said children under Grade 4 should stay with 10 % . But it is also important that older children don’t stay with over 15 %, because their bodies are still growing. "Children are losing their balance(平衡) and falling down with their school bags, "he said.
Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.
One of the best answers is, as some children said, to have no homework at all!
小题1: From the passage we can know that .
| A．only children in China carry too heavy school bags |

答案
小题1:C
小题1:B
小题1:A
小题1:D
小题1:B
解析
本文讲的是书包太重给学生带来的问题。
1. C 细节题。根据Not only the students in China have this problem, but children in the United States also have heavy school bags可知不但中国学生有书包太重这个问题，而且美国也有，故选C。
2. B 细节题。答案来自说话的内容：It’s hard for me to go upstairs with my bag because it’s so heavy，可知是书包重导致的结果，故选B。
3. A 定位到第二段，根据younger and younger students are having back and neck problems as a result of schools bags being too heavy for them可知是学生的背部和颈部出现了问题，故也受到了伤害，选A。
4. D 此题是个计算题。从文中Doctors say students should carry no more than 10% to 15%及don’t stay with over 15 %可知，最大的承受量是30*15%＝4.5，故选D。
5. B 细节题，答案来自文章最后一句，One of the best answers is, as some children said, to have no homework at all是说不要做任何的作业，故选B。

mobile phones can also be used to read e-books.
Earlier e-books were written for a specific group of readers and were about only a few subjects. With the development of the internet, knowledge and answers to a lot of questions mainly come from e-books. This is why the e-book business is increasing quickly
E-books have many advantages. First, they save time. We don’t need to go to a bookstore to buy books, besides, we can find the topic we want to know about on the Internet, and then we can quickly get many e-books on similar topics. Second, e-books save money. Some e-books cost a little money, and there are millions of e-books on the Internet that we can get for free. Third, more trees are saved because e-books don’t need to be printed(印刷) on paper. Fourth, e-books make reading more convenient. You can carry a whole library of hundreds of books with you in a small computer or any e-book reader (电子阅读器) without worrying about their weight.
But e-books have certain disadvantages. They need a personal computer or an e-book reader and the information can be lost if its file format (文件格式) is not supported or changed in the reader’s computer.
However, e-books provide us with a new way of reading. That is good.

Less homework will give students more time to enjoy other pastimes(休闲活动).I have many books which I received as gifts from my parents and friends. They have been kept there on my shelf for several years! Because of homework, I will have not read a single one of them. With less homework, students will be freer to develop their interests in art, music and other hobbies.
More time free from homework will get our physical health better. Many students
like sports, but they have little time to play football, basketball, volleyball and so on. They hardly have time to have a trip or take part in any social activities. They must spend so much time solving math problems and doing grammar exercises. Besides, staying up late to finish their homework leaves many students exhausted in the morning. Not getting enough sleep is not only unpleasant; it also makes students more likely(有可能得)to get colds and other illnesses.

Scientists studied 132 children in Canadian schools. At the beginning of the school year, these children took an IQ test. Then they were divided into four groups. One group took singing lessons. Another group took weekly piano lessons. The third group took classes in drams(戏剧). And the last group did no special activities at all.
At the end of the school year, the 132 children took an IQ test again. In all four groups, the average score went up. However, the piano players’IQs went up 7.0 points on average. The average increase for the other three groups was only 4.3 points.
The researchers say that the difference is small and it may not result in better grades for the piano players. However, they still consider the results important. Learning an instrument helps kids becomes better at concentrating and at memorizing things. Therefore, the researchers say, it may be good for brain development in young people.
If you have a chance to learn to play a musical instrument, never miss it. Remember it can make you smarter.

The animal trainers ‘found that a kind of rats from Africa were clever and had.a sharp* sense of smell. The rats were about 75 cm long and.weighed about l.35 kg, light enough to run across a minefield without setting off the mines.
In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed that, the trainers then taught them to tell the difference between the smell of mines and other smells. When the rats could do it, the click was sounded and they were given a bit of banana. The method was called clicker training. “The training isn’t easy, said trainer Abdullah Mchomvu. “You have to be patient. Sometimes I get angry, but then again, I tell myself these are animals.”
After nine months’training, the rats were taken to a minefield. They’ran across the minefield, stopped, sat and scratched the ground to tell the deminers* that they smelt out’a mine. Then the mine was cleared. It had taken two ‘deminers a day to clear a 200㎡ . minefield, but with the help of two rats ‘they could finish it in two hours.
The rats and the deminers saved thousands of lives, “The rats did this job much better than we expected. So far they have helped to make almost 2,000,000㎡ of land safe. They are heroes,” said Bart Weeqens, the head of the APOPO.
小题1: The APOPO trained the rats to search for .
| A．children | B．animals | C．mines | D．bananas |
| A．patient | B．clever | C．brave | D．serious |
| A．Two hours. | B．One day. | C．Four weeks. | D．Nine months. |
| A．Each day about 200 people were killed or hurt by mines, |
| B．The APOPO started to train the rats in January 2004. |
| C．The trainers gave the rats food after they smelt out a mine. |

If you are feeling anxious, my advice is to first find the cause or causes. Make s list of those things that are making you nervous and work out which ones you can do something about. Focus all of your efforts on managing the causes that you can control.
Most people cannot tell the difference between controllable(可控制的) and uncontrollable causes, so things they can’s control become a big reason for nervousness. Dealing with this is very important if people want to keep a healthy mind.
Simply try to accept the uncontrollable causes of nervousness. You might be worried about the weather on a big day, an accident or an attack on the train, or perhaps just things that other people are doing at work. The results may be very important but there is still no use worrying because you can’t control any of these things. Accept that you can’t control everything. Once you understand this, it becomes easier not to worry.
If a situation, such as swimming, is causing you to be anxious, try to face it as often as possible so that you can get used to it.
It can often help to think about yourself doing the thing that makes you nervous—then close your eyes and imagine it going well. Imagine how the flight or job interview is going to happen so that you can get used to it. This will help you understand that the thing you fear most is probably not going to happen.
