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 |

You're rushing to get out of the door for a meeting, but you just can't seem to find your car keys. Or you've got tickets booked for a Caribbean cruise(坐船旅行) , but your passport disappeared. Or maybe you've just come back from a grocery store tour and realized…Hey, did I leave my baby in the checkout line?
Ok, you've probably never gone to the extremes of our last example (we hope), but most of us experience slip - ups like these on a daily basis. No matter how smart you may be, it doesn't mean your brain won't turn to Swiss cheese every so often, and no amount of e-mail reminders can help you remember where you left your TV remote or lucky penny.
But now, there is a new pair of eyeglasses that can help to find all those little things you know must be around somewhere : Let's call it Vision 2.0.
The new glasses, which are being developed in a Japanese lab under the code name Smart Goggles,are similar to a Google search engine for your eyes. The high - tech glasses come with a camera that records everything you see on a daily basis, and boast built - in object recognition software that allows them to keep track of whatever comes across their field of vision. If you've got a collection of art sculptures that the camera can't recognize immediately, no problem : Just say the name of each item, and the glasses will memorize them right away.
The Smart Goggles' superb tracking abilities mean that whenever you're looking for your keys, your overdue library book, or yes, even your baby, all you have to do is to say the word and the Goggles' camera will show you the last time your desired object appeared on screen, telling exactly where you'll be able to find it.
Though the glasses are still too big for general use, the research team in Japan believes that they'll be able to make the modem glasses smaller to the size of normal glasses in the near future, making them the perfect new accessory for yourself or any other absent - minded Professor you know.
With these intelligent designs, you'll never lose anything again. Except maybe your glasses.The best title for the passage should be _______.

In the United States, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what "keeping up with the Joneses" is about. It is the story of someone who tried to look as rich as his neighbors.
The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began eaming $ 125 a week at the age of 23. That was a lot of money in those days.He got married and moved with his wife to a verywealthy neighborhood outside New York City. When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.
It was like a race, but one could never finish his race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They moved back to an apartment in New York City.
Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it " Keeping up with the Joneses" because "Jones" is a very common name in the United States. " Keeping up with the Joneses" came to mean keeping up with rich lifestyle of the people around you. Momand's series appeared in different newspapers across the country for over 28 years.
People never seem to get tired of keeping up with the Joneses. And there are "Joneses" in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.Some people want to keep up with the Joneses because they______.

| B．want others to know or to think that they are rich |

You might say that one reason why Barack Obama is president of the US is that he knows how to give a good speech.
Since 2004, Obama has written and delivered thousands of speeches. These are usually praised for two reasons: he treats the audiences like intelligent（有智慧的） adults, and he is able to express complicated ideas in an easy, natural way.
Before becoming president, Obama was a lawyer, a college professor, and a successful writer---his two memories have become best-sellers.
What’s more, he has some secret weapons.
Teleprompter: Obama doesn’t go anywhere without his Teleprompter. The textbook-sized panes of glass holding the president’s prepared remarks follow him wherever he goes to speak.
Writing team: Obama has a team of people who write his speeches. The writers chat with Obama for hours about what he wants to say. They listen to recordings of past presidential speeches and seek advice from advisers. Obama usually edits(编辑)and rewrites the drafts(草稿)several times.
Tricks for lighthearted speeches:
Make fun of the guests: Obama starts his speech by gently teasing his guests. His opening lines draw the audience’s attention while giving them an opportunity to relax and laugh at themselves and each other.
Make fun of yourself: A good rule for speechmakers: If you’re going to make a joke about someone else, be sure to make one about yourself, too. Obama mocks(嘲弄) his own poor choices for filling the position of Commerce Secretary, saying, “No president in history has ever named three Commerce Secretaries this quickly.” In fact, his first two nominees（被提名人）for the position withdrew(撤出) their names for different reasons. In a process that had otherwise gone smoothly, the Obama Administration found it hard to deal with the problem of filling the Commerce seat.Obama made the poetic and inspiring speech in 2004 as________.
| A．president | B．a nominee for the presidency |
| C．a senator | D．a secretary |
What’s the meaning of the underlined word in paragraph 2?
| A．Difficult to understand. | B．Easy to understand. |
| C．Different from others. | D．Interesting to say. |
From the passage, we know that Obama’s secret weapons are all these EXCEPT ____.
| A．a writing team | B．a teleprompter | C．humor | D．motivation |
What’s the best title of the passage？
| A．Secrets of Obama’s successful speeches. |
| B．Obama’s successful speeches. |
| C．Obama’s way of making speeches. |
| D．Problems of Obama’s speeches. |
