辽宁师范大学附属中学2013三模英语试题答案(4)

    With more responsibility，you will find more freedom to make your own choices. This is a time to be well informed about your choices so that you can make healthy balanced decisions that will help shape your future. You may already know your career path or you may have no idea at all what you want to do. Both situations are fine！Work hard and the right opportunity will present itself to you.
    Young adulthood means greater freedom and more choices. You will probably want to be
independent. But try not to shut your family out of your life. You should learn to think of others even though you are old enough to look after yourself. Your family have been with you since you came into this world.
    It is also perfectly natural in this time for you to spend more time with your friends than your family. Choose your friends wisely. A true friend will stand by you no matter what happens. This period is part of the life cycle. There are some people who will be with you throughout life's journey and there will be some people with whom you part and go separate ways. Leaving school can be hard. The reality is that you may not ever see all of your classmates again.
    You are a young adult. It is your life. No one can live it for you. The choices that you make from now on will be your choices. So making the right choices will be important to you. Life is for living. Enjoy your life wisely!

D
    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.”
67. Babies born in summer are more likely to be shortsighted ____________.
    A. because the summer sun is too strong for babies
    B. because babies who are born in summer have lengthened eyeballs
    C. if exposed to much sunlight in the first weeks after they are born
    D. if parents don’t know a proper way to protect their babies’ eyes
68. Melatonin 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
69. 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
70. The underlined word “vulnerable” in the passage probably means __________.
    A. easy to be harmed                 B. resistant        C. protective                D. changeable
