【题目】No first lesson is more important than the one on personal safety for kids. The First Lesson of the New Semester, a TV documentary about how to protect oneself in times of emergency, is meant to provide school students with the knowledge on self-protection. It will help students in case of natural disasters, snowstorms or floods.

There are times when one can be helpless and hopeless in many life-threatening situations. But that does not mean we __________ the end of life at that time. Many examples show that enough knowledge about self-protection along with enough courage and determination can help many survive.

The most recent example is from May earthquake in Sichuan Province. When thousands of school kids were killed by collapsed (坍塌的) school buildings, all students from a middle school survives even without a single one being hurt. That's because of their timely and orderly escape, which they had been drilled in every semester.

Japan has set a good example for us in safety lessons. Survival exercises are held in Japanese schools every year. With different kinds of competitions and training, schools help the students be aware and capable of surviving disasters.

It's good to see this program is the core (核心) of a national campaign to warn students the importance of personal safety. Chinese Education Ministry has called on all schools nationwide to give lessons on self-protection knowledge in times of emergency every semester.

Life is weak but can be strengthened when one is armed with enough knowledge on how to best survive.

【题目】Babies born in summer are more likely to become short-sighted in late life, a study has shown.

As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.

They are advising all parents to put sunglasses on their babies during the first weeks.

Scientists had already established that over-exposure to sunlight caused shortsightedness in animals.

Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.

A study of almost 300,000 young adults-the largest of its kind-showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January.

Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen-causing short-sightedness.

Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.

The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.

In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.

Sight expert Professor Daniel O’Leary, of Anglia Ruskin University in Cambridge, said “At the moment we don’t know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming shortsighted.”

1Babies born in summer are more likely to be shortsighted ____________.

A. because the summer sun is too strong for babies

B. because babies born in summer have lengthened eyeballs

C. if they are exposed too much sunlight in the first weeks after they are born

D. if parents don’t know a proper way to protect their babies’ eyes

2Melatonin is a kind of material to ___________.

A. prevent the eyes from becoming near-sighted

B. protect the skin from harmful sun rays

C. make our body strong

D. protect babies’ eyes from summer sun

3】From what Professor Daniel O’Leary says we can conclude that ___________.

A. there is no evidence that shortsightedness is related to exposure to sunlight

B. whether light exposure affects sight still needs to be further proved

C. he believes that light exposure can cause shortsightedness

D. he tries to give the cause of why light exposure affects sight

4】The underlined word “vulnerable” in the passage probably means __________.

A. easy to be harmed B. resistant

C. protective D. changeable
