Earth Rocks On
　　Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years.
　　Scientists know that Earth formed about 4.5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust, eventually formed moving plates. Exactly when this shift happened, however, is an open question.
　　Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust (地壳) started shifting at least 3.8 billion years ago. The new estimate is 1.3 billion years earlier than previous ones.
　　Not long before 3.8 billion years ago, lots of asteroids (小行星) were pummeling Earth, keeping its crust in a hot, molten state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface as lava.
　　In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal(上地壳) belt. The rocky crust there is between 3.7 and 3.8 billion years old. The belt was once part of the seafloor, but now it is exposed to air.
　　The researchers recently look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of volcanic rock.
　　To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock, called magma(岩浆), flowed up slowly from deep inside Earth to fill the cracks. Finally, the area cooled, forming what we see today.
　　That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of a plate under the ocean, beginning around 3.8 billion years ago.
　　16 The ground beneath our feet is indeed still.
　　A Right
　　B Wrong
　　C Not mentioned
　　17 The shape of lands and oceans are slowly changed with the movements of plates.

　　18 Earth cooled down shortly after it was formed.

　　B Wrong
　　C Not mentioned
　　19 Scientists once estimated that Earth's crust started shifting three billion years ago.
　　A Right
　　B Wrong
　　C Not mentioned
　　20.It took a long time for the melted crust to become hard.
　　A Right
　　B Wrong
　　C Not mentioned
　　21.The formation of the Isua supracrustal belt is thought to have started about 3.8 billion years ago.
　　A Right
　　B Wrong
　　C Not mentioned
　　22. The lsua supracrustal belt is now a popular holiday resort.

　　B Wrong
　　C Not mentioned

The IPad
　　1 The IPad is a tablet computer (平板电脑) designed and developed by Apple. It is particularly marketed as a platform for audio and visual media such as books, periodicals (期刊), movies, music, and games, as well as web content. At about 1.5 pounds (680 grams), its size and weight are between those of most contemporary smartphones and laptop computers. Apple released the IPad in April 2023, and sold 3 million of the devices in 80 days.
　　2 The IPad runs the same operating system as IPod Touch and IPhone. It can run its own applications as well as ones developed for IPhone. Without modification, it will only run programs approved by Apple and distributed via its online store.
　　3 Like IPhone and iPod Touch, the IPad is controlled by a multitouch display-a break from most previous tablet computers, which uses a pressure-triggered stylus (触控笔). The IPad uses a Wi-Fi data connection to browse (浏览) the Internet, load and stream media, and install software. Some models also have a 3G wireless data connection which can connect to GSM 3G data networks. The devices is managed and synchronized (同步) by ITunes on a personal computer via USB cable.
　　4 An IPad has different features and applications one can use to execute different and interesting things. There are lots of IPad applications that the owner can use to enhance the way they communicate. Some of these are how to use social networking sites and other online options. One of the most common uses is for e-mail services. IPand applications like Markdown Mail allow the adoption of specific and particular options. They enable the owner to personalize their email accounts.
　　5 While the IPad is mostly used by consumers it also has been taken up by business users. Some companies are adopting IPads in their business offices by distributing or making available IPads to employees. Examples of uses in the workplace include lawyers responding to clients, medical professionals accessing health records during patient exams, and managers approving employee requests. A survey by Frost & Sullivan shows that IPad usage in workplaces is linked to the goals of increased employees productivity, reduced paperwork, and increased revenue.

第4部分：阅读理解（第31～45题，每题3分，共45分）
　　下面有3篇短文，每篇短文后有5道题。请根据短文回答其背面旳问题，为每题确定一种最佳答案。
第一篇 Cell Phones: Hang Up or Keep Talking?
　　Millions of people are using cell phones today. In many places it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication—having a mobile phone shows that they are cool and connected.
　　The explosions around the world in mobile phone use make some health professional worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.
　　On the other hand, why do some medical studies show changes in the brain cells of some people who use mobile phones? Signs of change in the issues of the brain and head can be detected with modern scanning (扫描) equipment. In one case, a traveling salesman had to retire at a young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.
　　What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.
　　As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often
　　31 People buy cell phones for the following reasons EXCEPT that
　　A they're popular
　　B they're cheap
　　C they're useful
　　D they're convenient
　　32 The world "detected" in paragraph 3 could be best replaced by
　　A cured
　　B removed
　　C discovered
　　D caused
　　33 The salesman retired young because
　　A he disliked using mobile phones
　　B he was tired of talking on his mobile phone
　　C he couldn't remember simple tasks
　　D his employer's doctor persuaded him to
　　34 On the safety issue of mobile phones, the manufacturing companies
　　A deny the existence of mobile phone radiation
　　B develop new technology to reduce mobile phone radiation
　　C try to prove that mobile phones are not harmful to health
　　D hold that the amount of radiation is too small to worry about
　　35 The writer's purpose of writing this article is to advise people
　　A to buy mobile phones
　　B to update regular phones
　　C to use mobile phones less often
　　D to stop using mobile phones
第二篇 Some People Do Not Taste Salt Like Others
　　Low-salt foods may be harder for some people to like than others, according to a study by a Penn State College of Agricultural Sciences food scientist. The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat.
　　Those conclusions are important because recent, well-publicized (大力宣传旳) efforts to reduce the salt content in food have left many people struggling to accept fare that simply does not taste as good to them as it does to others, pointed out John Hayes, lead investigator on the study.
　　Diets high in salt can increase the risk of high blood pressure and stroke. That is why public health experts and food companies are working together on ways to help consumers lower salt intake through foods that are enjoyable to eat. This study increases understanding of salt preference and consumption.
　　The research involved 87 carefully screened participants who sampled salty foods such as soup and chips, on multiple occasions, spread out over weeks. Test subjects were 45 men and 42 women, reportedly healthy, ranging in age from 20 to 40 years. The sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettes. They rated the intensity of taste on a commonly used scientific scale, ranging from barely detectable to strongest sensation of any kind.
　　"Most of us like the taste of salt. However, some individuals eat more salt, both because they like the taste of saltiness more, and because it is needed to block other unpleasant tastes in food," said Hayes. "Supertasters, people who experience tastes more tensely, consume more salt than nontasters do. Snack foods have saltiness as their primary flavor, and at least for these foods, more is better, so the supertasters seem to like them more. "
　　However, supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese, Hayes noted. "For example, cheese is a wonderful blend of dairy flavors from fermented (发酵旳), milk, but also bitter tastes from ripening that are blocked by salt," he said. "A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced.
　　Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named Blakeslee, showing that individuals differ in their ability to taste certain chemicals. As a result, Hayes explained, we know that a wide range in taste acuity exists, and this variation is as normal as variations in eye and hair color.
　　36 John Hayes pointed out that __________.
　　A food with less salt tastes better.
　　B many people never eat low-salt food.
　　C many people make efforts to accept low-salt food.
　　D it is good to health to eat food without salt.
　　37 The fourth paragraph briefly describes______?
　　A why the number of subjects was limited to 87.
　　B why more male subjects were chosen than female ones.
　　C how salty foods were made and distributed to the subjects in the research.
　　D how the subjects were selected and what they were asked to do.
　　38 It is true that ________.
　　A nontasters like to share salty cheese with supertasters.
　　B supertasters like the taste of saltiness to block sweet tastes in food.
　　C nontasters consume more salt because they like intense tastes.
　　D supertasters like snack foods more as they contain higher levels of saltiness.
　　39 Supertasters prefer high-salt cheese because ________.
　　A it is good to health.
　　B it tastes less bitter.
　　C it is rich in nutrition.
　　D it has intense bitter tastes.
　　40 It can be inferred from the last paragraph that taste a
