Recently I have done a survey on the hobbies of the 1,500students in our school.
The result showed that over 40% of them are fond of playing musical instruments in their spare time because it can improve their life quality.About 35% enjoy surf the Internet,which helps them know about world affair.That surprises me most is the number of the students paid much attention to reading and doing sports is smaller.Each only makes up for 12%,although one is a best way to gain knowledge and other is to keep fit.
However,many students are strongly advised to take on reading as knowledge is power.Plus,they should take an active part in sports and develop other hobbies proper besides entertainment.

9.We can stay young forever.That is the message Dr.Shen Ziyin wants to give the world.
And the Chinese doctor claims that he has found an answer to the problems of aging.His solution is a herbal medicine to slow the process of aging.
Dr.Shen Ziyin has been trained in Western medicine.At the same time he studied traditional Chinese medicine.And,he has been working for the past forty years to put together the best of both and find a cure for aging.He has taken a hint from the ancient Chinese medicine system called"Shen".
According to Shen,it is the kidney (肾) that adjusts the functioning of the body as well as its aging process.It is responsible for the level of activity that the human bodies go through.Studies conducted by Dr.Shen show that herbal medicine based on the Shen system slows the aging process.
We notice that when people grow old,they have reduced strength,loss of hair,backache,weakness in general,and wrinkles.This happens because when people grow old,their bodies produce T-cells.These T-cells contain a particular substance called Fas.Fas makes the cells in the body destruct themselves.
So the only way to slow down aging is to slow the production of T-cells in the body.This can happen if people eat low-calorie food.Then the body is not active enough to produce extra T-cells.But,is going hungry all the time a good price to pay for staying young?
This is where Dr.Shen's herbal medicine comes.But how effective it will be,only time can tell.
28.How did Dr.Shen find the solution to the problem of aging?D
A.By studying Western medicine.
B.By learning traditional Chinese medicine.
C.By doing research on both Western and Chinese people.
D.By combining both Western and Chinese medicine.
29.What plays the most important role in keeping people young according to Shen?B
A.Medical treatment.
B.People's good kidney.
C.Level of people's activity.
D.Positive life attitude.
30.The reason why people become old is thatA.
A.their bodies produce T-cells
B.their bodies are unable to fight diseases
C.they have reduced strength,loss of hair
D.they become weaker and weaker
31.We can probably learn from the passage thatD.
A.producing more low-calorie food allows people to keep young
B.the more Chinese herbal medicine people drink,the better for health
C.people should try to quicken the production of T-cells in the body
D.it remains unknown how effective Dr.Shen's herbal medicine is.

10.Africa is a very diverse land with many different tribes.One tradition that many of these groups share is painting or marking their bodies and faces in color.They do this for many reasons.Some marks are used to identify people as part of a group.(36)B Let's look at some different examples of body painting.
(37)A Among the Masai of East Africa,when men are old enough to marry and make decisions for their people,they participate in a special ceremony in which they paint their heads and faces red.This ceremony takes place every seven to fourteen years,so there is not an exact age for participating in it.The Samburu,also from East Africa,like to paint their faces and hair red because they think it looks attractive.
(38)D To show that he has killed a lion,a man will paint his body with a natural white material,making special marks to represent this accomplishment.The Masai men also use this white to show that they are no longer boys and are considered adults.
One quite unusual example of face painting is done by the Wodaabe people of West Africa.Once a year,they have a beauty contest for men. (39)G Then they add white and black circles and lines.Black paint is used near the eyes and on the lips to draw attention to the whiteness of their eyes and teeth,which the Wodaabe consider most beautiful. (40)E.
As you travel,enjoy the beautiful and bright colors of Africa.

A.Red is the common color in body painting because it often represents health and long life.
B.Other marks are used for ceremonies such as weddings and during times of war.
C.The ceremony expresses hope for rain.
D.The Masai men also have a unique way of showing that they are brave.
E.The women then decide which man they like best.
F.The men pretend to fight each other.
G.The men paint their faces yellow and red.
