The brain, rather than our eyes, may be more important for sight, researchers studying fruit flies have discovered. The discovery could change the way we think about vision.
Researchers in the University of Virginia have found that the very simple eyes of fruit fly larva (幼虫), with only 24 total photoreceptors (感光细胞) (the human eye contains more than 125 million), provide just enough light input to allow the animal’s large brain to make that input into images. Their discovery shows that vision may be less important to “seeing” than previously thought—and in fact it is the brain’s ability to process points of light into complex images that is key.
“It blows open how we think about vision.” said Barry Condron. “This tells us that visual input may not be as important to sight as the brain working behind it.”
Condron’s graduate students, Elizabeth Daubert, Nick Macedonia and Catherine Hamilton, conducted a series of experiments to test the vision of fruit fly larvae. They found that when a larva was tied to the bottom of a dish, other larvae were attracted to it as it attempted to free itself. After several further experiments to understand how they sensed the motion, the researchers learned that the nearly blind animals likely were seeing the action.
“The answer must be in the brain of these animals.” Condron said. “They are able to take just a couple dozen points of light and then process that into recognizable images; something like when an astronomer with a small telescope is able to use techniques to improve a limited image into useful information about a star.” Condron believes the animals are able to assemble useful images by rapidly scanning their heads and, in doing so, gather up enough light points to allow the brain to compose an image clear enough to “see”.
The researchers tested this by presenting larva with a video (therefore no sound and no smell) and found that the larvae still sensed and sought out the struggling larva on the video. This provides us with a good model for trying to understand the role that the brain plays in helping organisms, including humans, to process images, such as recognizing faces.
1.The writer mainly wants to tell us that __________.
A.the brain may be more important for sight than people thought
B.people should depend on brain rather than eyes for sight
C.using the fruit fly larva to test the eyes is the best way
D.some methods can keep our eyesight accurate and normal
2.The researchers chose the fruit fly larva because it __________.
A.doesn’t move very quickly B.has a very wise brain
C.only has a few photoreceptors D.doesn’t have large limbs
3.Condron used the example of “an astronomer with a small telescope” in Para. 5 to show __________.
A.how the larvae gather up enough light points
B.why the larvae moved their heads side-to-side
C.the brain helps process the light points into images
D.how we can get useful information about a star with a small telescope
4.The underlined word “assemble” in the fifth paragraph may mean “__________”.
A.observe enough actions B.receive useful information
C.choose proper equipment D.put together separate parts

''Will you stop where those two steps are?'' the boy asked. He ran up the steps. Then after a little while Jack saw him coming back, but he was not coming fast.

And some day I’m going to give you one just like it. . . then you can see for yourself all the pretty things in the Christmas windows that I've been trying to tell you about.”

Dazzling (眼花缭乱) with their bright colors and eye — catching displays, fireworks light up our night skies during the holidays. However, these crowd -pleasers can have some damaging side effects. Once a firework is set off, it only takes a couple of seconds before smoke, dust and harmful chemicals are let out into the atmosphere. The loud booming noises are caused by gunpowder. While the sounds may excite some people, they can be frightening to domestic and wild animals — as well as some humans.
The pretty colors you see are a result of more chemicals. Barium, added to make green, is known for its poisonous and radioactive qualities. Blue comes from copper compounds. Cadmium, lithium and lead — all found in fireworks — have been linked to diseases, such as allergies and skin rashes in both humans and animals. Acid rain has been linked to gases given off by fireworks, which sometimes go beyond the toxin (毒素) limits of the United States Clean Air Act.
Once all those chemicals come back down to the ground, they can cause problems too. Debris (碎片) from the fireworks falls to the ground, where animals can bum their paws or noses on piping hot pieces. Humans also are at risk of stepping on or picking up something sharp or hot. Meanwhile, debris that finds its way into waterways can damage animal habitats and water supply sources. Instead of setting off fireworks, try to come up with some new ways for fun. Here are some ideas to get you started:
Sky lanterns — a tradition that originated long ago in the most-populated Asian country.
Party crackers — a favorite in the United Kingdom — give you noise and surprises without the mess of fireworks. You can make your own or buy eco-friendly crackers.
Want noise excitement with less volume? Consider a fireworks sound recording beforehand or break out the party horns (号角) and blow up a storm!
1.The advantages of fireworks can be seen below EXCEPT that _________.
A.the special sounds of fireworks excite people
B.the pretty and bright colors add to the beauty of night skies
C.fireworks are enjoyed as one of the crowd-pleasers
D.debris from fireworks can even find its way into water
2.Which of the following is NOT true according to the passage?
A.Chemicals in fireworks are both poisonous and dangerous.
B.Too much gases from fireworks can result in acid rain.
C.Copper compounds are needed to make green in fireworks.
D.Chemicals in fireworks are harmful in the air and on the ground.
3.What is implied from the passage?
A.Gunpowder in fireworks makes loud booming noises.
B.It must be Indians who first started to hang sky lanterns.
C.Fireworks can even break the balance of nature.
D.Fireworks does less harm in the air than on the ground.
4.What can be concluded as the writer’s attitude towards fireworks?
A.It is not allowed to set off fireworks except during the holidays.
B.Night is the best time to set off fireworks and see the pretty colors.
C.You cannot set off fireworks unless you come up with new ways.
D.Fireworks should be banned and replaced by some other means.

Last winter, when I was heavily pregnant, I was visiting my sister and sister-in-law's house and had to park in a nearby parking lot because they didn't have accessible parking. The snow was extremely heavy and there was lots of ice on the ground — not many people had ventured out that evening! When I returned to my car around 11 pm, I noticed that I was the only car left. Nervously, I jumped into the car and let it warm up a bit. When I finally tried to drive away, my wheels began to spin. I was stuck! I spun and spun and wondered what to do.
All of the sudden, in my rear view mirror, I saw four teenaged boys approaching my car. They were walking side-by-side in a line and dressed a bit like gang members — at least I thought that’s what they looked like. My car was in a very isolated area and I began to panic. I was certain they were coming to my car to harm me. Terrified, I just froze. One of the young men tapped on my window and said ''Excuse me, Ma’am, can we help you? You seem stuck.'' Still afraid and fearing the worst, I said ''I am stuck.'' And the young man said ''It's okay, stay in your car and we'll push you out of the snow.'' And they did!
When they finally got me out of the snow, they smiled and waved. I rolled down my window and thanked them, embarrassed to have judged them so poorly.
1.Which of the following words can best describe the four young men?

3.Which of the following is true according to the text?
