Good posture is an indication of good health. It also adds to a body‘s vitality and beauty. The body is not handsome when the back is bent and the neck thrusts forwards. Bad posture creates the impression that a person is tired， lacking in energy， bored， or weak. Fatigue may sometimes be the cause of bad posture. Most often， however， it is due to carelessness and poor health habits. Whatever its cause， bad posture affects one physically. The muscles are stretched and pulled into unnatural positions， which can lead to poor functioning of the body’s various systems.
Nutrition is the study of how the body takes food and uses it. This science provides information about the kinds of food a person must eat to promote and maintain good health. Such knowledge helps him develop and apply proper nutritional habits to his problems of healthful living. Proper habits of nutrition can be developed by paying attention to： （1） the variety of foods included in the diet； and （2） the quantity of each kind of food eaten. A diet， or the food regularly eaten， must contain all the nutritional elements.
Many physicians believe that overweight is one of the greatest dangers to good health. This condition often leads to a shorter lifespan.

2.Declining Interest in Developing Foreign Language Skills
Australias foreign language skills are declining， Voice of America has reported. New figures show that only 13 percent of high school graduates can speak a foreign language. But four decades ago， 40 percent had foreign language skills.
Professor Elise Tipton， from the University of Sydney， says increasingly students do not feel the need to learn another language to boost their career. She believes that Australias economic boom， which is driven by red-hot demand for its minerals， is helping mask serious deficiencies in its language skills.
Australia does business very successfully in English with most of its trading partners. But as the worlds economic power shifts to emerging regions such as Asia， its language gap could soon be exposed. According to the new figures， less than 6.5 percent of high school graduates are proficient in an Asian language. Academics worry that this means Australia will increasingly be isolated from its economically important Asian neighbors. Dilip Dutta， from the economics and business faculty at Sydney University， says language skills can enhance trading opportunities. If Australians want to trade with Asian countries， it is very important for them to learn the language that will help them to get closer to the culture.
But students have different opinions about Asian language learning. Pippa McCowage， a 22-year-old Australian student， says many young Australians have a half-hearted approach to foreign languages3， and the language curriculum is often weak. “While were encouraged in high school to learn another language， its not really apparent to me as a realistic expectation that you will have to speak it，” said McCowage. “For example， I learned Japanese in high school， when I went on an exchange in Year 10， I found that the Japanese students of my age had a much greater proficiency in English than I did in Japanese. So in that sense， it almost discourages you.
At present， about 70 percent of Australias major exports go to Asia and the Australian government has been keen on developing closer economic and diplomatic ties with Asia. Academics say that， as Asia becomes one of the worlds economic powerhouses， Australia needs to improve its language skills if it is to take full advantage of the business opportunities on its doorstep.
（1）.How much percent of high school graduates were proficient in foreign languages forty years ago？
（2）. What can be inferred from paragraph 2？
A. Australia has rich deposits of minerals.
B. Australia is essentially a self-sufficient country.
C. Australia has no intention to trade with Asian countries.

（3）.What does Dilip Dutta think language skills can do？
A. Improve your relation with your partner.
B. Help settle international conflicts.
C. Remove barriers in negotiations.
D.Increase trading opportunities.
（4）.Why has the Australian government been keenly interested in strengthening ties with Asia？
A. Because Asia is where Australia is located.
B. Because Asia is where Australias major exports go.
C. Because Asia is where Australians go and spend their holidays.
D. Because Asia is where Australia can play a big role in international affairs.
（5）.The word faculty in paragraph 3 can be replaced by
It is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions， the basis for the decisions we make， and the roots of our habits and skills are to be found in our past experiences， which are brought into the present by memory.
Memory can be defined as the capacity to keep information available for later use. It includes not only “ remembering” things like arithmetic or historical facts， but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile.
Memory exists not only in humans and animals but also in some physical objects and machines. Computers， for example， contain devices for storing data for late use. It is interesting to compare the memory storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100，000 “words”—— strings of alphabetic or numerical characters——ready for instant use. An average U.S. teenager probably recognizes the meaning of about 100，000 words of English. However， this is but a fraction of the total amount of information which the teenager has stored. Consider， for example， the number of faces and places that the teenager can recognize on sight.
The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a person‘s memory is in terms of words and combinations of words. But while language greatly expands the number and kind of things a person can remember， it also requires a huge memory capacity. It may well be this capacity that distinguishes humans， setting them apart from other animals.
（1）.What do the sentences at the beginning of the passage suggest？
A. Memory is useful.

（2）. According to the passage， memory is helpful in our daily life in the following aspects except

（3）. With respect to the memory storage capacity， what is the author‘s idea about the comparison between human beings and computers？
A. Computers have no memory at all.
B. Computers are more powerful than adults.
C. Teenagers are inferior to computers.
D. Human beings are far superior to computers.
（4）. What is the major characteristic of a human being‘s memory capacity according to the text？
A. It can be expanded by language.
B. It can remember all the combined words.
C. It may keep all the information in the past.
