【题目】 Have you wondered why you have two eyes and why they are set close together on the front of your face? The reasons are simple and important to the way you see the rest of your world．
Your eyes are like two small cameras. A camera catches an image of an object and records it on film．Similarly，when you look at something，each eye takes in what it sees and sends this image to the back of the eyeball．Because your eyes are set close together，they view the world from about the same height but from slightly different angles. Working as a team, the eyes send the images to your brain, which puts them together into a single, centered image.
Seeing in stereo means seeing with two eyes working together，which is called stereoscopic sight．This allows you to view the world in three dimensions，or 3-D．Seeing depth helps you to judge the distance between you and the objects you see and to adjust to the changing angle at which you see something as you move closer to or farther away from it．If images are coming from only one eye, however，only two of these dimensions-height and width-can be perceived．A world seen with one eye is thus two-dimensional，as in a photograph．
Now consider why your two eyes are on the front of your face．Think of other animals with this same arrangement．They are all animals that hunt，like lions and wolves．Their eyes face directly in front of them．This provides a field of sight about 180 degrees wide，which is called binocular sight．On the other hand，animals that are hunted have eyes on the sides of the head，which provides nearly 360-degree field of sight．In order to stay alive，they need to see things coming from the sides and from behind．However，without stereoscopic sight，they have difficulty determining how far a danger is．
With sight both stereoscopic and binocular，humans share with animal hunters the ability to see from side to side and to accurately determine the distance．If you think it would be great to have another type of sight，perhaps with hundreds of tiny eyes like many insects do，think again! Each tiny insect eye sees only a tiny part．Besides，what if you needed glasses? Be glad for the eyesight that you have．
【1】According to the passage，an eye is like a camera because both
A. can record images
B. can imagine objects
C. provide centered images
D. work at the same height
【2】Stereoscopic sight is a result of having
A. a three-hundred-sixty-degree field of sight
B. hundreds of eyes，all seeing parts of an image
C. two eyes close to one another that work together
D. one eye on either side of the head，each seeing a different image
【3】The author implies that “seeing in stereo”
A．is similar to the way cameras work
B．is an ability humans are fortunate to have
C．would be better for a wider field of sight
D．helps people to have better sight than animals

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.

【题目】Humans aren’t the only ones getting a buzz from coffee．Caffeine can improve memory among honeybees and lead to better pollination(授粉)．According to a recent study published in the journal Science．
The study was conducted by a team of researchers at Newcastle University in the United Kingdom．They found that the nectar(花蜜)of some flowers，such as those from grapefruit and lemon plants，as well as certain coffee flowers，contains low doses of caffeine．To get bees to feed on these flowers，the team trained the insects to associate food with the smell of the flowers．They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine．After 24 hours，the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants．
Professor Geraldine Wright led the researchers．“Remembering floral traits(花部特征)is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are，”Wright said in a statement．
Improved memory led to the better pollination．That’s because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate．This also suggests that caffeine plays a role in improving the bees’ability to search for food．
Researchers found that caffeine’s effect on the bee brain is similar to its effect on mammals．“The change is similar to that produced by caffeine in neurons(神经元)associated with learning and memory in the rat brain，”Wright said．
span>Bee populations have declining since 2007．The dramatic drop in the insects’numbers has serious effects for ecosystems and the farming industry．Bees are needed in the reproduction of crops and spreading wild flower species．Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers．
【1】Which of the following is mentioned in the passage?
A．Caffeine has no effect on the rat brain．
B. Bee population has been increasing．
C．The nectar of lemon plants contains caffeine．
D．Bees dislike nectar from sweetened flowers．
【2】After reading the passage，John，who works in the farming industry, will probably feel________.
A．annoyed B．angry C．nervous D．excited
【3】Which of the following relationship is correct according to the passage?
A．improved memory—caffeine nectar—better pollination
B．caffeine nectar—improved memory—better pollination
C．improved memory—better pollination—caffeine nectar
D．caffeine nectar—better pollination—improved memory
【4】What section of a newspaper may this passage be taken from?
A．Science B．Education
C．Culture D．Sports

【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.”
【1】Babies 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
【2】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
【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
