All too often, a choice that seems susta...

All too often, a choice that seems sustainable(可持续的)turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol(乙醇) for fuel from corn. Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea. 

   One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land –including, in some cases, rain forest in places such as Brazil—into farmland, which in turn gives off lots of carbon dioxide (CO) into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.

   You cannot really declare any practice “sustainable” until you have done a complete life-cycle analysis of its environmental(环境的) costs. Even then, technology and public keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainably requires plenty of thought on an ongoing basis.

1.What might directly cause the loss of the forest according to the text?

A. The growing demand for energy to make ethanol

B. The increasing carbon dioxide in the air

C. The greater need for farmland

D. The big change in weather.

2.The underlined word “it” in the second paragraph refers to “           ” 

A. the energy benefit                                              B. the forest loss 

C. climate change                                           D. burning ethanol 

3.The author thinks that replacing gas with corn ethanol is           . 

A. impractical                    B. acceptable               C. admirable         D. useless 

4.What does the author mainly discuss in the text? 

A. Technology                          B. Sustainability

C. Ethanol energy            D. Environmental protection 

 

1.C 2.A 3.A 4.B 【解析】 试题分析:作者主要谈论的是可持续性发展的判断依据以及用相关一些事实来进行佐证其论点。 1.C推理判断题。注意问的是直接原因。That result leads to turning the fallow land — including, in some cases, rain forest in places such as Brazil — into farmland(这个结果会导致一些休闲地<在一些情况下,包括位于巴西等地的热带雨林>被转化为农场)。 2.A词义猜测题。根据上下文可知是指能源优势。 3.A推理判断题。根据全文可知作者认为用corn代替gas是不符合实际的,会带来很多意想不到的问题。 4.B主旨大意题。读完全文我们可以知道,作者主要谈论的是可持续性发展的判断依据以及用相关一些事实来进行佐证其论点。该题容易误选D。 考点:议论文类阅读理解

Nowadays more and more people are trapped in too busy work to relax themselves. We have no time to tell a bed-time story to our children, or enjoy a nice dinner with our family, or take a break to think about how we live the precious life, or even meet friends. All we notice is that the distinctions that used to guide and steady us —between Sunday and Monday, public and private, here and there—are gone. We have more ways to communicate, but less and less to say. Partly because we’re so busy communicating.

   Maybe that’s why more and more people I know, even if they have no religious belief, seem to be turning to yoga, or meditation, or tai chi. Some friends of mine try to go on long walks every Sunday, or to “forget” their cell phones at home. A series of tests in recent years has shown that their brains become both calmer and sharper after spending time in quiet rural settings.

  In my own case, I often turn to extreme measures to try to keep my sanity and ensure that I have time to do nothing at all. I’ve not yet used a cell phone and I’ve never Tweeted or entered Face book. I try not to go online till my day’s writing is finished, and I moved from Manhattan to rural Japan.

  None of this is a matter of principle or asceticism (苦行主义): it’s just pure selfishness. Nothing makes me feel better-----calmer, clearer and happier----than being in one place, absorbed in a book, a conversation, a piece of music. It’s actually something deeper than mere happiness: it’s joy, which David Steindl-Rast describes as “that kind of happiness that doesn’t depend on what happens.” That is the highest of the highest we have been longing for—The Joy of Quiet.

1.The writer sometimes doesn’t do anything because ________.

A. he is out of work

B. whatever he does makes no sense

C. he can enjoy himself in his leisure time

D. he is worried about his writing

2.What does the writer mean when using the word “forget” (in the 2nd paragraph)?

A. Trapped in busy work, they are really forgetful.

B. They think cell phone is not a suitable means of communication.

C. They leave their cell phones at home on purpose.

D. They hate modern techniques such as the cell phone.

3.Which of the following is right?

A. The writer is unwilling to help others since he is selfish.

B. Slowing down to find deep-down joy is necessary.

C. It is better to go back to the ancient times since we are so busy now.

D. We have more to say because we have more ways to communicate.

4.What is the main idea of the article?

A. The importance of spending time in quiet.

B. We can do some sports such as yoga to relax.

C. To feel better, we should do nothing at all.

D. The more we communicate, the better we will feel.

On a freezing-cold February morning in Indiana, Jhaqueil Reagan,18, left home to walk to a job interview—ten miles away, over snow-covered roads.

Reagan had been looking for work for months. His mother had died two years earlier, and he was the only caretaker of his younger brother, Cole, 16, and sister, Jazzlyn, seven. He was desperate for a regular salary after cutting lawns(草坪) and doing other temporary jobs.

Three hours into his hard trip, Reagan had covered only three miles. He paused outside a Cajun restaurant called Papa Roux to ask for directions from owner Art Bouvier, who was clearing ice and snow from the parking lot. “I told him to get on the bus,” says Bouvier. “He thanked me and went on his way.”

Fifteen minutes later, Bouvier pulled up in his car beside Reagan as he walked along. “You’ve really got to be on the bus,” he told Reagan. “I don’t have money for the bus,” Reagan replied. Bouvier offered him a lift. On the way, he asked the boy about his job search.

“I thought, This is the kind of kid I want working for me,” says Bouvier. He got the teen’s phone number and dropped him off for his interview.

Later that day, Bouvier wrote about Reagan on Facebook. “He doesn’t know it yet, but he starts on Monday,” Bouvier wrote. “It’s been a while since I’ve met someone so young with a work ethic(伦理) like that!” A few hours later, Bouvier called to offer Reagan a job. Shocked, the teen accepted on the spot. A television reporter caught wind of the story and interviewed the pair on camera that night.

Today, Reagan is washing dishes, filling orders, and greeting Papa Roux customers for $8.50 an hour. The publicity(宣传) has brought in so many new customers that Bouvier plans to open a second restaurant by the end of the year.

1.Why did Jhaqueil Reagan have to find a job ?

A. Because he had to make enough money to support his family.

B. Because his parents had died two years earlier.

C. Because he wanted to change his job.

D. Because he was desperate for a good job.

2.Which of the following can be used to replace the underlined part in the sixth paragraph ?

A. reported           B. delivered              C. heard         D. told

3.Which of the following words best describes Bouvier?

A. honest             B. warm-hearted           C. modest       D. independent

4.What’s the best title of the passage ?

A. A Young Man Who Had an Interview        B. A Young Man Who Found a Job

C. A Boss Who Offered a Job                 D. A Boss Who Took a Chance

Good Housekeeping has discovered that even if a child wear a helmet when she bikes, or skates, it may not protect her from a serious head injury.

Every year, 390,000 children under age 15 go to hospital emergency rooms with bike-related injuries. Of that number, about one third children suffer head injuries and an estimated 200 die. By wearing a helmet, a child can reduce her risk of injury by as much as 85 percent. But remember —— a bicycle helmet must fit properly to be safe. Here are five steps to making sure your child's helmet fits properly.

1) If you haven't bought your child's helmet already, you might want to consider one with a rear stabilizer(稳定杆). A rear stabilizer holds the back of the head gently and helps the helmet stay correctly positioned.

2) The helmet should fit closely and shouldn't slide from side to side or front to back. If your child can put two fingers on both temples inside the helmet, it's too big. Try a smaller size. But if the next size down is too small, use the fit pads(护垫). Fit pads come in different sizes and attach to the helmet with Velcro.

3) Tell your child to open her mouth widely and ask if she can feel the helmet push down onto the top of her head. If she can't, you need to readjust her helmet.

4) To prevent strap slippage, wind a rubber band around the strap where it meets the fastener.

5) Recheck the fit regularly.

You should replace the bicycle helmet:

If she has been in an accident with it.

If the buckle(金属扣) breaks or if a piece breaks off.

If it doesn't have a U.S. Consumer Product Safety Commission, American Society for Testing and Materials, or Snell Memorial Foundation sticker.

If it doesn't fit correctly. Even if the helmet fit perfectly two years ago, it might be too small now.

1.Who is this passage mainly written for?

A. Children.          B. Teachers.         C. Parents.        D. helmet producers.

2.What does the author mainly want to stress in the second paragraph?

A. The bike-related injury is a serious threat to the children.

B. The bicycle helmets must fit properly while the children are biking.

C. It’s necessary for the children to wear helmets while biking.

D. Many students suffer bike-related injuries every year.

3.If a girl finds a helmet a little bit big for her head, what should she do?

A. She must buy a smaller size.               

B. She can use some fit pads.

C. She can put fingers on both temples inside the helmet.

D. She must make helmet slide from side to side.

4.Phil White, a father, found the buckle of his girl’s helmet broken, he can_______

A. buy a new bicycle helmet for her

B. mend the bicycle helmet himself

C. continue to use the bicycle helmet

Ethiopia has greatly reduced its death rates for children under the age of five years during the last two decades, new UN statistics show. The report says Ethiopia has cut the number of child deaths, by two thirds or so, to 68 per 1,000 births compared to that in 1990.

The government owed the improved figures to its growing economy. Despite the reduction, the UN Children's Fund said Ethiopia needed to do much more to improve health facilities(设施) for pregnant women.

Ethiopia is one of Africa's poorest states, although it has experienced rapid economic growth in recent years and is one of the continent's leading coffee producers. Its economy centers around agriculture, which in turn relies on rainfall.

The BBC's Emmanuel Igunza in the capital, Addis Ababa, says Ethiopia was once representative of poor nutrition in Africa. But the latest UNICEF(联合国儿童基金会) figures show Ethiopia is one of the few African countries on the path to realizing the development goal of reducing child death rates, he says.

Ethiopia's Health Minister Kesetebirhan Admasu said increasing family incomes had helped improve people's health. "This has also resulted in better nutrition for children and women; this has translated into better medical conditions —— all these have a direct or indirect influence on the survival of children," he told BBC Africa. He said the government has also been "aggressively expanding its primary health care network". 

"We have now 93% coverage( 覆盖) of one health centre for 25,000 people, which basically means one health facility within a 7km area," he said.

1.How many in 1000 births would die in Ethiopia in 1990?

A. about 680                 B. about 330         C. about 68                 D. about 200

2.Which of the following statements is true?

A. Ethiopian children benefit from its fastest economy growing.

B. Ethiopia has a long way to go to improve health facilities.

C. Ethiopia is the economic center because of its rich rainfall.

D. Ethiopia has already become a rich state in Africa.

3.What do we know according to the latest UNICEF figures?

A. Many African countries have high child death rates now.

B. Ethiopia is the only country that has reduced child death rates.

C. Ethiopia is the most successful in reducing child death rates.

D. Ethiopia was once known for its poor nutrition in Africa.

4.What Kesetebirhan Admasu said shows that_______.

A. agricultural incomes have helped improve all the people's health in Africa

B. now the health care network is perfect in Ethiopia

C. 93% of the 25,000 people enjoy health centers in Ethiopia

D. the government has been taking active measures to improve people's health
