一、现代文阅读（6分）阅读下面的文段，完成1～3题。

重拾中华之“礼”的当代价值彭林东西方文化，是当今世界的两大文明，两者的关键区别究竟何在？梁启超说“中国重礼治，西方重法治”，将东西文化归结为“礼”“法”二字。

钱穆赞扬此语“深得文化分别之大旨所在”。

数十年后，钱穆又说：“要了解中国文化，必须站到更高来看到中国之心，中国的核心思想就是礼。

”梁启超、钱穆将中国文化的核心归结为礼治，绝非向壁虚构，而是渊源有自。

在中国人看来，人是按照礼，也就是理性要求来生活的，其他的动物则不能。

人有文化自觉，不可与鸟兽同群；通过礼自别于禽兽，对于中国人而言，礼是人生第一要义。

礼也是文明与野蛮的区别，这是更高一个层次的区别。

孔子作《春秋》，欲为万世龟鉴。

春秋乱世，本质上是文明与野蛮的斗争，即“礼”与“非礼”的斗争。

而历史的进步，是在文明战胜野蛮之后。

礼是社会一切活动的准则、修身的主要门径。

中国文化要求人们努力修为，成为道德高尚的君子，甚至成圣成贤，其间的取径，则是礼乐人生、内外双修。

因此，中国人在童蒙教育阶段即教以礼，不学礼，无以立。

从束发开始，每逢人生的转折点，也都会寓教于礼，通过冠礼、婚礼、相见礼、饮酒礼、射礼、丧礼、祭礼等一系列“人生礼仪”进行指导，在总体上维持了全民族的文明水平。

更为重要的是，礼是民族凝聚的核心。

中国幅员辽阔，南北四方发展不平衡，各地风俗更是歧异，对政府而言，如果没有统一的行为规范，听之任之、放任自流，不堪想象。

经过两千多年的经营，礼超越于方言、风俗之上，彼此说话可以听不懂，年节习俗可以互异，但在礼的层面上却能彼此认同，这是中国特有的文化现象，也是中国在历史长河中始终保持统一趋势的深层原因。

AMy first child was due in a couple of months. All of my shopping was done except for one thing. When my little brother was born, my mom had bought an old fashioned, red-velvet baby carriage (童车). Ever since then, I wanted one for my child.I knew that this would be hard to find. So, Mom offered to take me around. Even used carriages cost quite a bit, and I had only $35 to spend. I hoped that I could only use the money I had. Early one Saturday morning, we drove for about an hour to a city with flea markets, and second-hand stores.As we searched place after place without even seeing a baby carriage, we'd take turns saying, “It will be at the next stop." I lost hope as the day passed and it was getting dark. I was ready to give up. My mom wanted to go to one more store. On the way there Mom told me I should never lose hope.When we got to the store, I took a deep breath. I knew that this was my last chance. My mom's words began to ring in my car: "Never lose hope." As we walked in, I made a quick rush down the middle of the store. There was one brand-new, red-velvet baby carriage. I ran over to touch it because I could hardly believe my eyes.I was so excited that I couldn't say a word. When I calmed down, it occurred to me that, because it was new, I probably couldn't afford it. The saleslady said it came with the store when she bought it several years ago, and that it had been in storage until just this morning. She said she wanted to get rid of it as a bargain and was only asking $35. You can imagine how happy we were on our way home.

Also, think about those forks and spoons in your school cafeteria. They may probably be plastic. Plastic seems to be everywhere—even in the oceans.Back in the 1990s, a man named Charles Moore discovered a huge floating island of plastic in the North Pacific Ocean. Since then, four more floating islands of plastic have been discovered in other places. Now, Moore says, the island is growing and spreading much farther. He made that discovery during a 30-day research expedition (探险)."They found a lot more plastic farther away from the area called the Great Pacific Garbage Patch than they've ever seen," said Marieta Francis, the executive director of the AMRI—an institute that Moore created to investigate the floating plastic problem.Right now, experts say they're not sure what all this plastic is doing to the health of our oceans or our own health. They suspect that small fish are eating tiny bits of the plastic—and that then they are getting into bigger fish when they eat the small fish. Of course, we're at thetop of the food chain. So that means if the plastic is getting into the big fish, then it's getting into the fish we eat—and then into us.Moore and other researchers hope to figure out what effect all that plastic is having. But right now, experts say their research is still in its very early stages. "What we do know for sure right now is that 10,000 to 35,000 tons of plastic is floating on the surface of our oceans. And we humans put it there," said Moore.25. What can we learn from the first paragraph?A. Plastic has a terrible effect on people's life.B. Good use has been made of plastic in people's life.C.

Well, make plans to try it now since you are on summer vacation. Not all vacations call for taking a tour bus to take photos of famous landmarks. Some vacations allow you plenty of opportunities to learn.The most difficult part of a learning vacation may be a choice because the possibilities are endless. If you enjoy cooking, various companies can take you to Italy, France, Spain, Mexico or even Peru. Once there, you can learn about the local cuisine (烹饪). Trips are often planned to fit in with local food festivals or special events.The term "learning vacation" often brings languages to mind. The best way to learn a language is to immerse（使沉浸于) yourself in an environment where it's spoken, whether you study Spanish, French or English, or attempt to learn a more unusual language like Polish, Estonian or Thai. You'll be able to learn about the country and absorb the culture at the same time.If you are fond of sports, you can polish your skills or learn new ones. Golf and tennis schools welcome players of all levels. If you want a bigger thrill, you can learn to surf, go climbing or race cars.

The scenic locations of the schools offer plenty of subjects that provide inspiration for practice.If you prefer capturing (捕获) the world on film, take a photography vacation. Travel with a small group to photograph beautiful animals or scenery. You can also practise your techniques on people or at historical sights.Once you decide on a vacation, choose a company carefully.

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 percent 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. Therefore, the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be. The mechanism (机能) which lengthens the eyeball is associated with levels of melatonin, 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 exact cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming short-sighted."32. Babies born in summer are more likely to be short-sighted __________A. because they usually have lengthened eyeballsB. because the summer sun is too strong for babiesC. if parents don't kn ow a proper way to protect their babies’ eyesD. if exposed to much sunlight in the first weeks after they are born33.

What does the underlined word "vulnerable" in the third paragraph probably mean?A. Easy to be harmed.B. Easy to be absorbed.C. Easy to be protected.D. Easy to be changed.35. What can we conclude from what Professor Daniel O'Leary says?A. There is no evidence that short-sightedness is related to exposure to sunlight.B. Whether light exposure affects sight still needs to be further proved.C. He tries to give the cause of why light exposure affects sight.D. He believes that light exposure can cause short-sightedness.第二节七选五阅读（每题2分，共10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
