With petroleum reserves (石油储量) decreasing, the search is on to replace gas with a cleaner, greener alternative. Though much eco-talk has centered on biofuels from corn and soybeans, the biofuel that looks more likely to replace petroleum comes from a most unlikely source: algae (藻类). Algae, like corn, soybeans, and other crops, grow via photosynthesis (光合作用) and can be processed into fuel oil. However, they yield 30 times more energy than land crops such as soybeans, according to the U.S. Department of Energy. Many algae species also can grow in saltwater and polluted water — while corn and soy require arable land and fresh water that will be in short supply as the world’s population balloons. “If you replaced all the diesel (柴油) in the U.S. with soy biodiesel, it would take half the land mass of the U.S. to grow those soybeans,”

says Matt Caspari, chief executive of Aurora Biofuels, a Berkeley, Calif-based private firm that specializes in algae oil technology. On the other hand, the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States, it would require 15,000 square miles, which is a few thousand miles larger than Maryland (12,407 square miles), the 42nd state in land area.

Another bonus: Because algae can be grown just about anywhere in a closed space, they’re being tested at several power plants across the nation as a carbon absorber. Smokestack emissions (烟囱排放物) can be pumped directly into the ponds, feeding the algae while keeping greenhouse gases out of the atmosphere. Although processing technology for algae fuel—also known as “oilgas”

in some environmentalist circles—is improving, it’s still years away from reaching your local gas pump. “It’s just a question of cost, because no large-scale facilities have been built yet.” Caspari says. 1. The underlined word “yield” in the second paragraph can be replaced by . A. control B. require C. produce D. grow 2. Compared with corn and soybeans, algae . A. may pollute water and soil B. can grow in poor conditions C. provide much less energy D. need more special care 3. According to the third paragraph, one of the advantages of algae fuel is that . A. it can be used more widely B. it is more easy to produce C. it needs much less land D. it costs much less money 4. What do we learn about algae from the fourth paragraph? A. Algae help protect the environment. B. People can grow algae anywhere. C. Fish can get more oxygen from algae.

Giving up smoking will most likely add seven years to ones life. While many people try to give up and fail, it is not an impossible task. Follow these five tips, and you will be well on your way to giving up smoking. 1. Success in all fields of life begins with firm determination. If you are weak in willpower, you can never do anything. However, if you make up your mind, once and for all, that you are giving up the habit, whenever you want a smoke, you will remember your promise and not give in. 2. If you sit around doing nothing there is a higher chance that you will light up a cigarette and relax. Fill your spare time with sports and energetic activities. Try to feel how good it is to get your blood circulating and to breathe in air deeply. If you are not the athletic type, then walking will have the same benefit as other kinds of sports. 3.

and then light up, maybe it is better to avoid that place for the time being. Once you have truly stopped smoking and you feel how good it is, you can go anywhere and not be tempted. But while you are in the transition phase, it is better to carefully choose where you will spend your recreational time. 4. Whenever you get a desire to put a cigarette in you mouth, replace it with something that will help you rather than harm you. Drinking small amounts of water throughout the day is not only a good way to help you give up smoking, but it is also a great way to stay healthy. You should drink eight glasses of water per day, if you can. If you need to put something solid in you mouth, then eat a piece of fruit. 5. Tell them that you are giving up smoking for health reasons. Your true friends will support you and not offer you cigarettes. Your family and loved ones will similarly support your efforts and help you to avoid situations where you may feel you have to smoke because of social pressure. A. Learn How To Resist The Temptation B. Do Not Make Yourself Less Active C. Escape Your Social Pressure D. Amuse Yourself In Proper Places E. Get Support From Your Friends And Family

F. Swear Not To Smoke

Ⅰ.阅读理解

A (2017·潍坊4月模拟) home. The old animal spent her days out in the open country eating sweet grass. When the cow heard Sylvie's voice calling her, she would hide among the bushes, unwilling to go home. This evening it had taken Sylvie longer than usual to find her cow. The child hurried the cow through the dark forest, following a narrow path that led to her grandmother's home.

“Hello, little girl，” a young man called out cheerfully. “I've been hunting for birds, but I've lost my way.” The young man explained he was a scientist, who searched for birds. “Do you put them in a cage？” Sylvie asked. “No，” he answered, “I shoot them and deal with them with special chemicals to preserve them.”

“I saw a white heron (苍鹭) not far from here two days ago. It's a very rare bird. Have you seen it, too？” he asked Sylvie. Sylvie's heart began to beat fast. She knew that strange white bird! The young man was staring at Sylvie. “I would give $10 to the person who showed me where the white heron is.”

Sylvie had a plan that she would get the $ 10 for her grandmother and make the young man happy. Her plan was to climb to the top of a tall pine tree to see where the white heron had hidden its nest. The pine tree seemed to grow taller, the higher that Sylvie climbed. Suddenly a bird with broad white wings flew past Sylvie and landed on a pine branch below her. The white heron sat on its nest in a nearby tree. Sylvie gave a long sigh. She knew the wild bird's secret now. Slowly she began her dangerous trip down the ancient pine tree. About an hour later Sylvie returned. Both her grandmother and the young man stood up as she came into the kitchen. The splendid moment to speak about her secret had come. But Sylvie was silent. She could not tell the heron's secret and give its life away. 【解题导语】

本文是一篇记叙文，讲述了小女孩Sylvie最终因为她的善良而没有把白苍鹭的栖息地告诉年轻的科学家的故事。

1．Where would Sylvie usually meet the cow every evening? A. In the open country. B. Among the forest. C. On a narrow path. D. In the bushes. 答案与解析：D 细节理解题。根据关键句可知，Sylvie是在灌木丛中遇到这头奶牛。故D项符合题意。

【关键句】When the cow heard Sylvie's voice calling her, she would hide among the bushes, unwilling to go home.(第一段最后一句) 译文：当这头奶牛听见Sylvie叫她的声音时，她就会藏在灌木丛中，不愿意回家。

2．What was the young scientist's job according to his introduction? A. Collecting birds. B. Raising birds. C. Observing birds. D. Protecting birds. 答案与解析：A 推理判断题。根据关键句可推知，这个年轻的科学家的工作可能是收集各种鸟类标本。故A项符合题意。

【关键句】．.. I shoot them and deal with them with special chemicals to preserve them.(第三段最后一句) 译文：……我射杀它们，并用特殊的化学药剂来处理它们，目的是保存它们。

3．What had Sylvie planned to do about the white bird? A. Make good friends with it. B. Prevent it from being caught. C. Find its nest but keep it secret. D. Find it for money and the man. 答案与解析：D 细节理解题。根据关键句可知，因为钱和这个年轻人，Sylvie想找到白苍鹭。故D项符合题意。

【关键句】Sylvie had a plan that she would get the $10 for her grandmother and make the young man happy.(第五段第一句) 译文：Sylvie有了一个计划，她可以为她的祖母挣10美元并且还能使这个年轻人高兴。

4．What saved the white bird's life at last? A. Grandmother's sympathy. B. The white bird's beauty. C. Sylvie's kindness. D. The young man's generosity. 答案与解析：C 推理判断题。根据文章最后一段的内容可知，当Sylvie找到白苍鹭的巢的位置，回到家之后，她决定不把这个秘密告诉这个年轻人，因为她不想白苍鹭丢掉性命。由此可推知，Sylvie是一个善良的小女孩。故C项符合题意。

【长难句分析】“I would give $10 to the person who showed me where the white heron is.”(第四段最后一句) 分析：本句是一个复合句。who引导定语从句，修饰先行词the person，在从句中作主语；where引导宾语从句，作动词showed的宾语。

译文：“谁带我去找白苍鹭，我就给谁10美元。”

B When students read articles about scientific discovery, they learn what worked. Scientists present the methods that got the best result. They often show only the results that are significant and important. What they won't show are the mistakes or failures that came first. Yet sometimes those mistakes pointed the way to success. It can take a long time and many experiments to achieve scientific success. Robbin, 16, and Annabelle, 15, learned that while working this summer in a biochemistry lab at Stony Brook University in New York. What's more, they learned that failure is not necessarily something to fear. “I like the idea of scientific research，” says Robbin. It's the basis for “every lesson you learn in school and

understanding everything you see in life”. This summer, Robbin has been working with Lauren, a chemistry student, who is making new drugs to fight harmful bacteria. At first, the tests made Robbin anxious. She worried that she might be making costly mistakes. But Lauren reassured her that finding out what doesn't work is“just part of the learning process”. With time, the teen got comfortable with the idea that every experiment wouldn't succeed. Annabelle also learned a lot about failure and success. She worked with graduate student Agnieszka Gil. “Sometimes I try something and it takes a while for the experiment to run.” This means that finding out whether Annabelle did something wrong can be a stressful waiting game, because “if you did something wrong you

need to do it again”. But she's now learning to be patient and not to expect instant success. In science, figuring out why something failed is what may just put them on the road to success. 【解题导语】

在阅读科学发现的文章时，人们往往对科学成就过度关心，其实科学成就往往是建立在无数次失败的基础之上的。Robbin和Annabelle在实验室里体会到了坦然接受实验失败的价值。

5．What impresses students most in articles about scientific discovery? A. Scientists' achievements. B. The reasons for success. C. The cause of mistakes. D. Stressful process of research. 答案与解析：A 考查细节理解。根据第一段的第一句“When students

read articles about scientific discovery, they learn what worked”以及第二段的第一句“It can take a long time and many experiments to achieve scientific success”可知，学生在阅读科学发现的文章时，对科学成就的印象最为深刻，故A项正确。

6．What can we learn from the passage? A. Robbin is a graduate student. B. Lauren managed to make new drugs. C. Annabelle learns the value of patience. D. Agnieszka expected instant success. 答案与解析：C 考查推理判断。根据倒数第二段的最后一句“But she's now learning to be patient and not to expect instant success”可知，Annabelle学会了耐心，不期望立即成功；据此可以判断，Annabelle知道了耐心的价值，故C项正确。

7．What did Robbin and Annabelle have in common in their experiments?

A．They did their experiments independently. B．They realized not all experiments would succeed. C．They assisted graduate students to make new drugs. D．They made severe mistakes in the experiments. 答案与解析：B 考查细节理解。根据第三段的最后一句“With time, the teen got comfortable with the idea that every experiment wouldn't succeed”可知，Robbin坦然接受了并不是每次实验都会成功的事实；根据第四段的最后一句“But she's now learning to be patient and not to expect instant success”可知，Annabelle学会了耐心，不期望立即成功；据此可知，Robbin和Annabelle的共同点是她们都意识到了不是每次实验都会成功，故B项正确。

While it may seem like everyone surfs the web these days, there is a fine line between casually checking your social media pages and having a full­blown Internet addiction.

Try keeping the lid closed when you are not using it. __3__ If you have a desktop PC, try not to go near it or put something over it like a sheet. Call people instead of sending instant messages or texts. If you are free on weekends, call friends and ask them to go outside. This will distract you from the computer. __4__ Use an alarm clock or timer.

Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and make sure that you get off the computer when the time is up.

【文章大意】

网瘾会给人们的生活带来很大的影响，本文就如何避免网瘾提出了建议。

1．D 上文谈到网瘾会导致你对生活的其他方面失去兴趣，下文的几条建议则是有关如何避免网瘾的，D项对全文起着承上启下的作用。

2．G 本段的主旨是“Admit you are at risk of an addiction”，再结合本段讲述的“越来越多的人有网瘾，这是一个普遍现象”可知，选G项“不要觉得不好意思，找到和你一样有网瘾的人，互相帮助去战胜网瘾”。

3．B 根据空前的“Try keeping the lid closed when you are not using it”可知，作者建议你不用电脑时，把它合上，故选B项“看不到电脑时，你用它的可能性就小”。

4．F 本段的主题是“给朋友打电话而不是在网上发信息”，上文的“call friends and ask them to go outside”与F项中的“phone your friends or ask for help in person”，还有上文的“on weekends”与F项中的“on weekdays”前后呼应。

5．C 本段的主题是“Use an alarm clock or timer”，作者建议使用闹钟或定时器来限制上网的时间，空前的“shutdown timer”与C项中的“shut down your computer after the set time”相对应。

【文章大意】

本文是一篇说明文，介绍了有着特殊用途的狗——治疗犬。它们能给病人带来心理上的安慰，能成为孩子的朋友。

1．a 考查冠词。依据本句中的“very popular pet”可知，此处应用不定冠词，表示泛指。

2．to do 考查固定用法。本句中应用不定式作后置定语，have sth. to do表示“要做某事”。

3．are known 考查时态、语态和主谓一致。分析句子结构可知，本句话缺少谓语动词，“a group of＋名词复数”作主语时，谓语动词用复数，dogs与know是动宾关系，此处描述的是一般情况，因此用一般现在时的被动语态。

4．which 考查定语从句。这是一个非限制性定语从句，先行词为“special training”。

5．in 考查介词。由句意可知，这些治疗犬可以到公共场所安抚那些需要帮助的人。in need表示“在困难时，在危难之中”，为固定搭配。

6．petting 考查非谓语动词。have fun (in) doing sth.表示“做某事有乐趣”。

7．pressure 考查名词。分析句子结构可知，此处应用名词，blood pressure表示“血压”。

8．their 考查代词。修饰名词mood要用形容词性物主代词，故用their。

9．friends 考查名词的数。根据句子的主语They可知，此处用名词复数。

10．more 考查比较级。句中的but暗示这些狗对孩子来讲不仅仅是朋友，它们会做得更多。
