1、Waving With LightIn the Sierra Madre mountain range of west central Mexico, the native Huichol people live much the way their ancestors did without electricity. That\'s because it\'s too expensive to string power lines to the remote mountain areas where they live. To help support themselves, the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. ａｎｄ　without electricity at home ｏｒon the road, they can only work during daylight hours. When it gets dark, they must stop whatever they\'re doing. Now, a team of scientists, designers, ａｎｄ　architects are using new technologies to provide the Huichol with light after the sun sets. The scientists\' technique involves weaving tiny electronic crystals into fabrics that can be made into clothes, bags, ｏｒother items. By collecting the sun\'s energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics "Portable Lights." Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy. "Our invention," Kennedy says, "came from seeing how we could transform technology we saw every day in the United States ａｎｄ　move it into new markets fｏｒpeople who didn\'t have a lot of money."At the core of Portable Light technology are devices called high-brightness light-emitting diodes, ｏｒHB LEDs. These tiny lights appear in digital clocks, televisions, ａｎｄ　streetlights. LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give of flight we can see. Ninety percent of energy produced by incandescent lights, however, is heat ａｎｄ　invisible. With all that wasted energy, bulbs burn out quickly. They are also easily broken. LEDs, on the other hand, are like tiny pieces of rock made up of molecules that are arranged in a crystal structure. When an electric current passes through an LED, the crystal structure produces light. Unlike incandescent bulbs, they can produce light of various colors. Within an LED, the type of molecules ａｎｄ　their particular arrangement determines what colｏｒis produced. LEDs are different from light bulbs in that____. 【单选题】

A.LEDs are incandescent lights while light bulbs are not.

B.LEDs have a metal coil while light bulbs have not.

C.LEDs emit colored light while most light bulbs don\'t.

D.LEDs are made up of tiny pieces of rock while light bulbs are not.

正确答案:C

答案解析:短文第6段对light bulbs进行了描述。第2句中的those glass bulbs即指第1句中的light bulbs。因此，LEDs不是incandescent lights（白炽灯），也没有金属丝。所以A和B均是错误的。最后一段第一句“LEDs，on the other hand，are like tiny pieces of rock made up of molecules that are arranged in a crystal structure”中的“like tiny pieces of rock”不等于pieces。

2、Meet Your MemoryMemory is something that cannot be seen, touched ｏｒweighed. It is thought to be abstract. It is a ｓｅｔof skills rather than an object. Neither is there a single standard fｏｒjudging a good ｏｒpoｏｒmemory. There are a number of different ways in which a person may have a "good" memory.Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the blain until it is needed; ａｎｄ　(3) retrieval (提取) refers to getting the material back out when it is needed.Memory consists of at least two different processes: short-term memory ａｎｄ　long-term memory. Short-term memory has a limited capacity ａｎｄ　a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), ｏｒgrouping separate bits of information into larger chunks. Long-term memory has an almost unlimited capacity.One measure of memory is recall, which requires you to produce information by searching the memory fｏｒit. In aided recall, you are given cues (提示) to help you produce the information. In free-recall learning, you recall the material in any order; in serial learning, you recall it in the ｏｒｃｅｒit was presented; ａｎｄ　in paired-associate learning, you learn pairs of words so that when the first word is given, you can recall the second word. A second measure of memory is recognition in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time ａｎｄ　how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.Paragraph 2 ______.【单选题】

A.Why do we forget things?

B.How do we measure memory?

C.What are the stages memory consists of?

D.What is the difference between short-term memory ａｎｄ　long-term memory?

E.What is memory?

F.Who may have a poｏｒmemory?

正确答案:C

答案解析:第二段只有一句话，主要讲述了记忆的形成主要包括三个阶段，即获得、储存和提取。C选项What are the stages memory consists of?（记忆是由哪几个阶段组成？）与其意思相符，故C为正确答案。

3、DietPersons who are overweight should watch their diet carefully in ｏｒｃｅｒto lose pounds. The best way to do this is to start a weight control program. At first it is wise to talk with your doctor. He can advise you of the number of calories you should have in your meals each day. He can tell you about exercising while on your diet. A good rule is to lose slowly. A loss ofa pound ｏｒtwo is plenty. Plan meals around foods you know. This means that it is wise to include foods that you are used to ａｎｄ　that are part of your regular eating habits. When you have lost the weight you wish, simple items can be added to your diet so that you can maintain the weight you want. While you are dieting, try to build a pattern of eating that you can follow later to maintain your desired weight. When dieting, choose low-calorie foods. Avoid such items as fats, fried food, sweets, cakes, cream ａｎｄ　soft drinks. Try to take coffee ａｎｄ　tea without sugar ｏｒcream. Snacks can be part of your diet. Fｏｒexample, a piece of fruit ｏｒa simple dessert saved from mealtime can be eaten between meals. Keep busy! This way you will not be tempted to go off the diet. Make full use of opportunities to exercise. Try walking instead of riding whenever possible. Happy dieting !According to the passage, which of the following statements is NOT true?【单选题】

D.As you are dieting, don\'t forget exercise.

正确答案:A

答案解析:第1段末尾，作者建议“A good rule is to lose slowly A loss ofa pound ｏｒtwo is plenty”，应该慢慢地减肥，选项A（医生会建议你迅速减肥）是错误的。

4、HalloweenHalloween is an autumn holiday that Americans celebrate every year. It means "holy evening", ａｎｄ　it comes every October 31, the evening before All-Saints Day. It used to be thought the most wonderful night of the year. It was the night when witches ａｎｄ　evil spirits came back on earth. People kept up many strange old customs in an effort to keep these evil things away. Farmers used to light big fires in their fields, ａｎｄ　the farm workers ａｎｄ　their families would walk around the fields singing old songs. Sometimes they would stop to hear the local priest offer prayers to the good spirits, ａｎｄ　ask them to help keep the evil ones away. Great care was taken that none of the farm animals were left in the fields. They would all be locked up safely in their stables, ａｎｄ　over each of the stable doors a few rowan leaves would be hung. Witches ａｎｄ　evil spirits would not go anywhere near the rowan tree. In more recent times, Halloween has become a time fｏｒthe parties, when children dress up as witches ａｎｄ　play all kinds of special games. After the games there is often a big supper with plenty of pumpkin pie, cakes ａｎｄ　a lot of other delicious things to eat. But fｏｒthe most part the children enjoy the fun of dressing up ａｎｄ　playing their favorite game of "Trick ｏｒTreat". They run down each street knocking on the doors crying loudly "Trick ｏｒTreat! Money ｏｒeat!", ａｎｄ　most people have some sweets ｏｒmoney ready to give them. Those that do not can expect maybe to have a tyre flattened, ｏｒtheir windows covered in soap. ｏｒthe children may just knock on the doｏｒａｎｄ　run away. Some children think of other people on Halloween. They carry boxes fｏｒUNICEF (The United Nations International Children\'s Emergency Fund). They ask fｏｒmoney to help poｏｒchildren all around the world. Of course, every time they help UNICEF, they usually receive a treat fｏｒthemselves, too. Every autumn, when the vegetables are ready to eat, children pick large orange pumpkins. Then they cut faces in the pumpkins ａｎｄ　put lights inside. It looks like there is a person looking out of the pumpkin! These lights are called jack-o\'-lanterns, which means "Jack of the lantern". But in this modern age many of the pumpkins are being replaced with plastic electric ones that can be brought out each year. Why did Halloween use to be thought the most wonderful night of the year?【单选题】

A.Because people thought at that night witches ａｎｄ　evil spirits came back on earth.

B.Because it was the time fｏｒparties.

C.Because it was an autumn holiday that Americans celebrated every year.

D.Because farmers were allowed to light big fires ａｎｄ　sing songs at that night.

正确答案:A

答案解析:第1段第4句实际是第3句的原因。以前人们把万圣节前夜看成是最好的一夜。在这个夜晚女巫和魔鬼精灵都重返地球。人们保留很多奇异的习俗将这些邪恶的东西赶走。因此选A。

5、Lakes, Too, Feel Global WarmingThere\'s no doubt, In the last few decades, the average temperature on Earth has been higher than it has been in hundreds of years. Around the world, people are starting to measure the effects of global warming ａｎｄ　trying to figure out what to do about it.Scientist recently used satellites to study the temperatures of lakes around the world ａｎｄ　they found that lakes are heating up. Between 1985 ａｎｄ　2009, satellites recorded the night time temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer by an average of about 0.045 degree Celsius per year.In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius in just 10 years. That difference may seem small you might not even notice it in your bath. But in a lake, slightly warmer temperatures could mean more algae (水藻) ａｎｄ　algae can make the lake poisonous to fish.The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming. The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That\'s going to be useful, since no matter the country is too big ｏｒtoo small can\'t ignore climate changes. Scientists aren\'t the only ones concerned. Everyone who lives on Earth is going to be affected by the rapid warming of the planet. Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse(温室) gases we put into the air.That\'s why the United Nations started the Framework Convention on Climate Change, ｏｒUNFCCC. Every year the convention meets, ａｎｄ　representatives from countries around the world gather to talk about climate change ａｎｄ　discuss global solutions to the challenges of a warming world.Scientists have been keeping records of lake temperatures fｏｒover 30 years.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题难度不大，答案依据比较明显，在文章第二段第二句：Between 1985 ａｎｄ　2009，satellites recorded the nighttime temperatures of the surfaces of 1671 akes.很明显，是24年，而不是30多年，题干和原文句意不符，答案是B。
