John Davis doesn¡¯t use his GPS system in his car. Instead of guiding the direction, the Delaware farmer uses it to determine where and how much fertilizer to use on the crops on his 4,000-acre family-owned farm. Technological advances like that last year helped Davis and other Ohio farmers set a record for corn product. Ohio's corn crop in 2009 total
ed 546 million bushels(ÆÑʽ¶ú), despite a cooler and wetter than normal spring, a dry summer and a delayed, wet harvest. Davis said. ¡°I knew it would be a good crop, but it was much better than we expected.¡±
A farmer can map his fields on GPS, spotting where soil turned out to be least fertile£¨·ÊÎֵģ© and using more fertilizer the next year in those areas where corn didn¡¯t grow as well.
Although Ohio farmers produced more corn, it was grown on less land than in past years. Total area used for corn in Ohio was 3.35 million acres, about the same as in 2008 but down from 3.85 million acres in 2007, said Dwayne Siekman, director of the Ohio Corn Growers Association. ¡°When you look at the total number of acres in Ohio used for corn, it¡¯s clear that farmers are able to do more with less,¡± he said. ¡°American farmers can grow five times more corn on 20 percent less land than they did in the 1930s, saying that modern farming techniques are necessary for a growing demand in the world today.¡± That technology includes using improved seeds that can withstand(ÈÌÊÜ) greater temperature extremes and pests, Siekman said.
Farmers aren't the only ones who benefit. Consumers(Ïû·ÑÕß) do, too, as food costs reduce in the face of ¡°enough supplies of corn,¡± said Fred Yoder, who runs a 1,500-acre corn, soybean and wheat farm in Plain City. ¡°This is the best, highest-producing corn crop that I've raised in 30 years,¡± he said.
1. Most people usually use the GPS system for ______.
A. driving their cars B. telling the position C. mending the car D. supplying the sunshine
2. The farmers in Ohio use GPS to ______.
A. check if the soil is fertile in some areas B. control the rain of the place
C. water the crops if the weather is dry D. draw the map of all the crops
3. Why did Ohio farmers produce more corn?
A. Because they expanded more land to grow corn
B. Because they turned to technological advances
C. Because they used more and more fertilizer.
D. Because they supplies themselves with more money.
4. From the passage, we can know _____.
A. John Davis hadn¡¯t expected a good harvest.
B. farmers grew less land than in the 1930s
C. improved seeds cost much more money
D. the output of corn in the same field is increased.

I ran across an old photo of him the other day, thinking of some old things. He¡¯s been dead for 25 years. His name was Rex.
36 was his favorite recreation(ÓéÀÖ). He had so much 37 in the water as any person I have known. You didn¡¯t have to throw a stick in the water to 38 him to go in. Of course, he would bring back a stick to you if you 39 throw one in.
That 40 me of that night, 41 he brought back a small box that he found somewhere--- how 42 nobody ever knew. Since it was Rex, it 43 easily have been half a race. The box wasn¡¯t a good one. It was just a 44 old piece that somebody 45. Still it was something he wanted, probably 46 there was some difficulty in transportation£¨ÔËÊ䣩. And that he thought could test his courage. We first knew about his achievement when, deep in the night, we 47 him trying to get the box up onto the porch(ÃÅÌü). It sounded 48 two or three people were trying to tear the house 49 . We came downstairs and turned on the 50 light. Rex was on the top step trying to pull the thing up, but it had 51somehow. And he was just holding his own(¼á³Ö×Å). I suppose he would have held his own 52 dawn if we hadn¡¯t helped him. The next day we carried the box miles away and threw it out. If we had thrown it out in a 53 place, he would have brought it home again, as a small token(ÏóÕ÷)of his strength in such matters. 54, he had been taught to carry heavy wooden objects about and he was 55 of his skill.

Last week I saw the release of the second part, and boy oh boy does it shows. But watching the film as a foreigner I felt I was missing out on something. Not knowing my Cao Cao's from my Zhou Yu's, I was not even sure whom I wanted to win. Certainly after the opening scene, in which Cao Cao is seen watching a game of Cuju, an ancient Chinese variation of football, I knew who had my support. After all, any man who enjoys his football is someone after my own heart. But after Cao Cao resorted to some evil strategies against his enemies in the south, I wasn't so sure he was the man I should be rooting for. And there is a lot more to Red Cliff 2 than just extravagant battle scenes. The film does not take itself too seriously. Conversations between leaders are littered with one-liners, many of which had the audience in laughter. There is even enough to keep fans of more romantic entertainment happy too. This includes a charming relationship between a southern spy£¨Õì̽£©and an innocent northern soldier. The characters' interaction provides some genuinely heart-warming moments in the middle of the battle. Clocking in at£¨½áÊøÓÚ£©around two hours, the film certainly does justice to the history story. When I walked out the cinema, I felt as drained£¨¾«Æ£Á¦½ß£© as Cao Cao's soldiers must have 1,800 years ago. 41.By expressing ¡°boy oh boy¡± in the first paragraph, the author seems to show that _______.
42.When did the author change his attitude toward Cao Cao?
43.The following factors of the film are all mentioned in the passage except_______.

Its look and feel are only slightly improved, but a faster network loads Web pages more quickly, true GPS functionality allows it to easily find places nearby, and the new $199 price (down from $400) makes it an affordable luxury. Before deciding whether to buy, however, make sure you can actually take advantage of the iPhone 3G's high-speed data network. 3G stands for third-generation, which in non-geek speak translates to Web pages and mail messages that, ideally, load about three times faster than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf the Web at the same time. That's great, if you live or work in a place where the 3G network of AT&T£¨ÃÀ¹úµç»°µç±¨¹«Ë¾£© (the sole wireless carrier of the iPhone) is active. That's not so great in cities like New York where AT&T's cellular coverage is awful. As one of my colleagues in New York City, who bought the original iPhone, commented, "It's just a toy. You can't make phone calls on it, so I carry my Verizon phone with me all the time." The real fun begins when you tap on the icon called "App Store" and start browsing the hundreds of add-on applications that have been developed just for the iPhone. You'll find tons of games (I like JirboBreak, a free game inspired by the Atari classic Breakout) and mobile versions of popular websites like Pandora, Facebook, MySpace and the New York Times. Most apps will cost you, but the vast majority are $9.99 or less. The apps work on the old iPhones too, but you'll enjoy them a lot more on the iPhone 3G because many of the programs, including Yelp (local business reviews), Whrrl (mobile social networking) and UrbanSpoon (restaurant reviews), use your exact location ¡ª provided by the iPhone 3G's GPS chip ¡ª to make recommendations. The apps also load much faster over the 3G network. 57.The new iPhone 3G has following features except that _______
58.Why do one of my colleagues carry Verizon phone with him all the time? ______.
59.Which of the following statements is NOT true according to the passage. ____.

Earlier studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere¡¯s eye stays open and alert. Birds also can sleep with both hemispheres resting at once. Decades of studies of bird groups led researchers to predict extra alertness in the end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction. Also, birds napping at the end of the line depend on single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four-duck row, the researchers found that compared with 12 percent for birds in internal spots, outer birds half-asleep during some 32 percent of napping time. ¡°We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain,¡± the researchers say. The results provide the best evidence for a long-standing assumption that single-hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He¡¯s seen it in a pair of birds napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open. Useful as half-sleeping might be, it¡¯s only been found in birds and such water animals as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning. Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds¡¯ half-brain sleep ¡°is just the tip of the iceberg.¡± He supposes that more examples may turn up when we take a closer look at other species. 65.According to the passage, birds often half sleep because ______.
66.What is implied about the example of a bird¡¯s sleeping in front of a mirror?
67. While sleeping, some water animals tend to keep half awake in order to ______.

As Sam Beattie reports from Beijing, there is widespread hope for closer U.S.-Chinese cooperation. For many students in Beijing, Mr. Obama symbolizes all that is possible in the United States. He's a popular winner here, seen as a self-made man who has made it to the top. "I think he is very charming, and a president who can create a new era," said Zhang Wei, a university student. "I like him very much and most of my friends do too." Ni Weibo, another university student, agrees. "Sino-U.S. relations still need more cooperation," she said. "I think he will help take it to a new era." China's President Hu Jintao congratulated Mr. Obama within hours of his victory, saying he hoped bilateral ties could be made stronger. Political analysts here say China will be looking for the incoming president to avoid contentious issues such as Taiwan's independence, human rights and Tibet. Instead, they say Beijing would like Mr. Obama to focus on solving the global economic crisis, and to help China's slowing economy by opening up U.S. markets. But trade relations might be a sticking point, says Renmin University's Professor of International Studies, Shi Yinhong. He warns, "There is a possibility that President Obama will take some protectionist measures which China will not accept, then trade disputes could develop to a degree that we have not seen ever before." Despite making the headlines, Mr. Obama faces some tough challenges in managing the U.S. relationship with China. China is now a stronger and more confident country than the China his predecessors dealt with. And in this time of economic uncertainty, analysts say it's a country with which Mr. Obama will want to maintain a good relationship. 73.What can we infer from the first three paragraphs?
