9．Up to 90% of school leavers in major Asian cities are suffering from myopia---short-sightedness，a study suggests．Researchers say the"extraordinary rise"in the problem is being caused by students working very hard in school and missing out on outdoor light．
Eye experts say that you are short-sighted if your vision is blurred（模糊的） beyond 2m．It is often caused by an elongation （拉抻）of the eyeball that happens when people are young．According to the research，the problem is being caused by a combination of factors-a commitment to education and lack of outdoor light．
Professor Morgan who led this study argues that many children in South East Asia spend long hours studying at school and doing their homework．This in itself puts pressure on the eyes，but exposure to between two and three hours of daylight helps maintain healthy eyes．
Cultural factors also seem to play a part．Across many parts of South East Asia₉children often have a lunchtime nap．According to Professor Morgan they are missing out on natural light to prevent short-sightedness．
A big concern is the numbers of the students suffering from"high"myopia．One in five of these students could experience severe visual impairment（障碍）and even blindness．These people are at considerable risk-sometimes people are not told about it and are just given more powerful glasses-they need to be warned about the risk and given some self-testing measures so they can get to an ophthalmologist and get some help．
For decades，researchers believed there was a strong genetic component to the condition．But this study strongly suggests an alternative view．"Any type of simple genetic explanation just doesn't fit with that speed of change； gene pools just don't change in two generations．Whether it's a purely environmental effect or an environmental effect playing a sensitive genome，it really doesn't matter，the thing that's changed is not the gene pool--it's the environment．"

47．As is mentioned above，which factor mainly results in students'myopia in South East Asia？C
A．Genetic faults of the people．
B．Elongation of the eyeball．
C．The shortage of outdoor light．
D．Lack of research into the problem．
48．Which of the following statements do you think agrees with Professor Morgan？D
A．A lunchtime nap is helpful in reducing myopia．
B．Glasses keep myopia from getting even worse．
C．It's necessary to treat myopia with an operation．
D．It's of vital importance to reduce educational pressure．
49．What's the main idea of the last paragraph？B
A．Gene remains the main cause of the long-standing problem．
B．The environment is to blame for the extraordinary rise in myopia．
C．Short-sightedness has nothing to do with changes in gene pools．
D．An environmental effect playing a sensitive genome counts．
50．What's the best way to take care of your eyes according to the passage？D
A．Equip the classroom with better lights．
B．Look at the sun from time to time．
C．Do eyes exercise regularly．
D．Spend more time in the open air．

6．The art of reading fiction is largely a matter of inferring meanings．To infer means to understand facts which are not directly stated-only suggested．Inference is one of the commonest ways of knowing things_： a child holds his knee and cries； this action implies his feeling； aji observer infers that the child hurt．To infer accurately in everyday life requires caution in observing； to infer skillfully in fiction requires caution in reading； both require disciplined imagination．
The short-story reader can expect to find certain basic elements in any story．For example，all stories involve a person or persons，in a particular setting，faced with a demand for a response．The response called for may be a physical action，such as defeating an adversary （对手） or escaping from a danger； or it may be a mental action，such as adjusting to others or within oneself．In either case，the short story is a description in two ways_： first，it shows the motives for a given，human action； second，it makes a point about the general human situation．Such descriptions，however，rather than being stated directly，usually are implied by the elements of the story．
When the reader of a story understands all the facts and their interrelationships，he is ready to infer the significance of the story as a whole-its comment on the human situation．This comment，or theme，is the seed from which the story grew．It is also the idea by which all the separate elements of the story are governed，while these in turn further shape and modify the theme．In addition to action，character，and setting，these elements include structure，mood，tone，and point of view．
Fiction reading requires an awareness of all the ways in which a story communicates．It also requires attention to detail．What the author provides is a network of points which serve as clues to his meaning．He invites the"reader to develop the meaning by inference，actually to create much of the story himself and so make it part of his own experience．
67．According to the author，"infer"meansA．
A．knowing facts beyond the statement
B．looking for more evidences for the statement
C．finding out a different meaning from the statement
D．adding some facts to the statement 68．Wh
68．t is inferring in fiction based on？B
A．Readers'guessing．
B．The basic elements of the story．
C．The setting of the story．
D．The interrelationships between people in the story．
69．What is the implied meaning of the last sentence？A
A．Inferring can really help the reader develop imagination and enrich himself．
B Inferring can help the reader write a story of his own．
C．The reader should look for an experience described in the story he reads．
D．The experience described in the story will leave a great impact on its reader．
70．What is the main idea of this passage？C
A．Inferring is an art of writing．
B．Inferring is a need in fiction writing．
C．Inferring is the basic skill in reading fiction．
D．Inferring is common in reading．
