With petroleum reserve（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(适于耕种的) 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 only l5, 000 square miles, which is a few thousand miles larger than Maryland (12,407 squaree miles), the 42nd state in land area.
Another advantages: 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 “oilgae” 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.The underlined word “yield” in Paragraph 2 can be replaced by “_______”.
| A．control | B．require | C．produce | D．grow |
Compared with corn a
nd soybeans, algae_____.
| A．may pollute water and soil | B．can grow in poor conditions |
| C．provide much less energy | D．need more special care |
Ac
cording to Paragraph 3, one of the advantages of algae fuel is that ____.
| A．it can be used more widely | B．it is easier to produce |
| C．it needs much less land | D．it costs much les s money |

In a very real sense, people who have read good literature have lived more than people who cannot or will not read. To have read Gulliver’s Travels is to have had the experience of listening to Jonathan Swift, of learning about man’s cruelty to man. To read Huckleberry Finn is to feel what it is like to drift (漂流) down the Mississippi River on a raft . To have read Byron is to have suffered his rebellions with him and to have enjoyed his nose—thumbing at (对……的蔑视) society. To have read Native Son is to know how it feels to be frustrated in the particular way in which Blacks in Chicago are frustrated. This is effective communication. It enables us to feel how others felt about life, even if they lived thousands of miles away and centuries age. It is not true that “We have only one life to live.” If we read, we can live as many more lives and as many kinds of lives as we wish.The sentence “People who have read good literature have lived more than people who cannot or will not read” suggests that ______.
| A．reading stimulates（激发）a desire to travel | B．reading broadens a person’s experience |
| C．people who read much live longer | D．people who read are more relaxed |
The author implies that good literature ______.
| A．must deal with social problems | B．must teach a lesson |

| C．satisfies the curious | D．opens new worlds to us |

A nobleman and a merchant once met in an inn. For their lunch they both ordered soup. When it was brought, the nobleman took a spoonful, but the soup was so hot that he burned his mouth and tears came to his eyes, The merchant asked him why he was weeping. The nobleman was ashamed to admit that he had burned his mouth and answered, “Sir, I once had a brother who committed a great crime , for which he was hanged. I was thinking of his death, and that made me weep.” The merchant believed this story and began to eat his soup. He too burned his mouth, so that he had tears in his eyes. The nobleman noticed it and asked the merchant, “Sir, why do you weep?” The merchant, who now saw that the nobleman had deceived (欺骗) him, answered, “My lord(="master)," I am weeping because you were not hanged together with your brother.”This story teaches us ______.

Dear Economist,
My newly-wedded wife and I are deeply in love．There is, however, one issue that threatens the happiness of our marriage．I absolutely insist on shopping at Walmart．My wife, meanwhile, would rather avoid Walmart at all costs．
I have recently tried to convince her that not only does Walmart offer the lowest prices known to man, but that the chain is also a force for good―lower prices mean better standards of living for all consumers, increased global trade means a tighter-knit(紧密团结的) international community, and efficient operations translate into higher productivity growth for the economy．My wife complains about poor labour policies, the “fact” that Walmart squeezes suppliers, and that it puts local shops out of business．
Who is right? Will our marriage survive?
Brian Gee
Dear Brian,
I have to agree with you about Walmart．Jason Furman, then an economist at New York University, now an adviser to President Obama, famously argued in 2005 that Walmart was unwittingly (不知不觉地) a progressive success story．The chain’s prices don’t much affect me (I prefer Whole Foods) but Furman estimated that they benefited low-and-middle-income Americans to the sum of around $250 billion a year．
Walmart does not pay much, so it may depress wages．Then again, it may increase wages by offering jobs to the otherwise-unemployed．Either way, the benefits of low prices to Walmart shoppers far outweigh any seemingly reasonable costs to Walmart employees．And while it is true that Walmart employees tend to be poor, the same is true of Walmart shoppers．
Armed with this information you can face your wife with confidence．You are sure to win the conversation．The divorce is likely to be more argued．
EconomistWhat concerns Brian Gee so much that he wrote the letter?
| A．His wife refuses to shop at Walmart． |
| B．They are faced with a divorce． |
| C．They can’t afford the costs of shopping at Walmart． |
| D．They are in conflict about shopping at Walmart． |
Brian Gee’s wife tends to hold the opinion that _________．
| A．it is wrong for Walmart to depress its employees’ wages |
| B．consumers’ lives have improved thanks to Walmart |
| C．Walmart’s business operation increases productivity in economy |
| D．Walmart’s business increases global trade |
What can be inferred from the reply letter?
| A．Some employees accept the low pay to keep the job． |
| B．Walmart appeals to only poor consumers and poor employees． |
| C．Employees suffer from Walmart’s low prices more than consumers． |
| D．Jason Furman, a New York University economist, spoke highly of Walmart． |
To be able to motivate oneself, or self-motivate, occurs when a person has the willingness to do something and is internally(内在地) motivated to do it．
Sometimes it’s very difficult to get ourselves moving．The natural tendency is to postpone．Life just seems to get in the way! There is a job to go to, groceries to do, television to watch—whoops! I guess we get pretty good at finding excuses to escape getting started on goals like an exercise routine or reading a new book．The fact is that we are creatures of routine and habit．So what can we do to motivate ourselves to accomplish our goals?
Here are some tips on how to get moving:
Decide what you want．It’s hard to motivate an aimless mind．Set a goal and decide how you are going to go about it．Then break it down into smaller sections so it’s easier to handle and less overwhelming．（势不可挡）
Keep track of your progress．Keep a log or journal where you can measure how much you have accomplished．Looking at it can also motivate you to keep pushing ahead．
Post motivating pictures or slogans within your sight．It is always inspiring to see pictures of people who have accomplished what you’re going for．It makes it attainable and realistic．Likewise, little slogans like “go for it” or “just do it” can give you the little support you need．
Sometimes we forget what we set out to do and a little reminder is all we need to be revitalized (激活) and focus on the end result．If you remind yourself to go for the desired promotion, it will re-establish why you are doing what you’re doing．
Make it a habit．Once you have accomplished your objective, e．g．becoming an early riser, keep it up so that it’s second nature to you and you don’t have to think about it anymore．According to the author, some people fail to achieve their goals because ________．
| A．they don’t have enough desire |
| B．their life is filled with routine work |
| C．they benefit from the force of habit |
| D．they naturally put off forming new habits |
It can be inferred from the underlined sentence that ________．
| A．self-motivation needs repeated self-reminding of one’s goal |
| B．in modern society people tend to become forgetful |
| C．when we forget our goal, our life becomes meaningless |
| D．we can achieve our goal only by focusing on the end result |
To get moving on your goal, you can do the following EXCEPT ________．
| A．keep a diary to clearly judge your distance to your goal |
| B．make self-improvement your second nature |
| C．forget your aim and revitalize yourself with slogans |
| D．support yourself by hanging inspiring pictures in your house |
Which of the following is the best title for the passage?
| A．Set Goals in Your Life | B．Get Yourself Motivated |
| C．Get into Good Habits | D．Do Not Postpone |
