With rising temperatures there’s concern for ...

With rising temperatures there’s concern for some freshwater fish. If the water gets too warm , then it can change their living activities .For some species in UK the river water needs to stay below 20℃. The problem is as the climate gets warmer so do the streams and rivers .The problem is particularly of concern for the smaller streams and rivers which respond to air temperature changes much more than the deeper and larger rivers .

The method to keep the temperatures of rivers down could be as simple as planting woodlands along the river course .Research has shown that trees cover lowland streams can keep water temperatures 5 ℃ lower than streams running through treeless environments .That 5 ℃  can make the difference between the water temperature being habitable for fish or being too warm for their living .

While it looks like a good method to a problem , there are things that need to be considered . We need to remember that trees are not the favorite habitat of all animals . Some of the habitats need open countryside . Trees can also bring their own problems .A nutrient  poor stream has its own life . Plant trees alongside it and leaves fall in the stream. Falling leaves can change the nutritional makeup of the stream , which will affect the stream and local species of the stream . You have to be careful with this type of management, but his method does offer a real chance to help freshwater living things against climate changes and increasing temperatures.

1.It can be inferred from the text that some freshwater fish ______.

2.An easy method to protect freshwater fish is to ________ .

3.Which of the following statements is TRUE about the method ?

4.What’s the main purpose of the text ?

There is growing concern about food insecurity in the developing world. Rising food prices, weather emergencies and political problems are deepening the struggle for families in many countries.

Three UN agencies have published a report recently, saying high prices are likely to continue. Gregory Barrow, who is with the World Food Program in Rome, says, “If you look at the places where the World Food Program works, particularly in developing countries, you see people who might be spending more than 60 percent of their salary in purchasing food for their families.”

East Africa is suffering its worst drought in years. In Kenya, at least three and a half million people are going hungry, mostly in the north. Yet food is going to waste in central Kenya. Now, farmers there want the government to buy their food and give it to those in need. Farmers say bad roads and lack of transportation make it difficult for them to get their produce to the market.

Mr. Barrow says, “It needs the government to make some arrangements such as providing transport. They can buy it at a good price, then give it to those people instead of asking for food from overseas, which is very bad. When we are throwing away food, they are asking for food from overseas.”

Economists say that imports reduce local food prices, decrease productivity(生产效率) and increase the dependency on other countries. Farmers in Kenya hope the government can pay higher prices for their crops so that they can feed more Kenyans.

1.What is the best title for this passage?

A. Kenya Imports Food from Abroad

B. A World Food Program in Rome.

C. The Poor Suffer from High Food Prices.

D. A Report Published by Three UN Agencies.

2.What do we know about Kenya from the passage?

A. The people in central Kenya are suffering from hunger.

B. At least three and a half million Kenyans lack food.

C. The Kenyan government wants to improve road conditions.

D. People in northern Kenya refuse to ask for food from overseas.

3.What does “they” in the fourth paragraph refer to?

A. The people of northern Kenya.

B. Government officials.

C. The farmers of central Kenya.

D. Kenyan economists.

4.Which of the following statements is TRUE, according to this passage?

A. Gregory Barrow suggests that Kenya make good use of overseas food.

B. People in northern Kenya are suffering the drought less than the central.

C. Economists believe importing food from abroad may cause problems.

D. Kenyan government hopes to buy the native crops at higher prices.

California has been facing droughts for many years, with certain areas even having to pump freshwater hundreds of miles to their distribution system. The problem is growing as the population of the state continues to expand. New research has found deep water reserves under the state which could help solve their drought crisis. Previous drilling of wells could only reach depths of 1,000 feet, but due to new pumping practices, water deeper than this can now be extracted (抽取). The team at Stanford investigated the aquifers (地下蓄水层) below this depth and found that reserves may be three times what was previously thought.

It is profitable to drill to depths more than 1,000 feet for oil and gas, but only recently in California has it become profitable to pump water from this depth. The aquifers range from 1,000 to 3,000 feet below the ground, which means that pumping will be expensive and there are other concerns. The biggest concern is the gradual setting down of the land surface. As the water is pumped out, the vacant space left is pressed by the weight of the earth above.

Even though pumping from these depths is expensive, it is still cheaper than desalinating (脱盐) the ocean water in the largely coastal state. Some desalination plants exist where possible, but they are costly to run and can need constant repairs. Wells are much more reliable sources of freshwater, and California is hoping that these deep wells may be the answer to their severe water shortage.

One problem with these sources is that the deep water also has a higher level of salt than shallower aquifers. This means that some water may even need to be desalinated after extraction, thus increasing the cost. Research from the study of groundwater has just been published. New estimates of the water reserves now go up to 2,700 billion cubic meters of freshwater.

1.According to the text, what causes the water crisis in California?

A.Previous drilling of wells. B.The messy distribution system.

C.Constant droughts in the area. D.The adoption of new pumping practices.

2.The research teams think it ________ to extract water from deeper aquifers.

A.expensive but practical B.reliable and profitable

C.cost-free but demanding D.cheap and environment-friendly

3.What is mentioned as a consequence of extracting water from deep underground?

A.The damage to aquifers. B.The sinking of land surface.

C.The decrease in operation costs. D.The negative effects on the climate.

4.What is the author’s purpose in writing the text?

A.To encourage people to save water.

B.To promote the seawater desalination.

C.To introduce a new way of extracting freshwater.

D.To draw people’s attention to the droughts in California.

Does your mood change with the seasons?

Some people find that when the temperature goes down, so do their spirits. 1. They eat more and gain weight. They have trouble sleeping. They can’t think clearly.

Here are some ways you can beat the winter blues:

Get out in the sun. Some experts say that winter blues happen because we get less sunlight in the winter than we do in other seasons. Some say that the decrease in sunlight can make us feel sad.2.

Get some exercise. A walk or other exercise will make chemicals called endorphins (内啡肽) flow through your body. Endorphins are natural “feel good” chemicals.

3. Avoid having too much sugar. If you crave sugary foods (like cookies or candy), it may be a sign that you need more protein (蛋白质), like meat, chicken, or fish.

Avoid holiday stress. Cut back if you have too many things to do. Make sure you have some quiet time to yourself.4. Get some rest. Studies show that most teens need about nine hours of sleep each night. The average teen, though, gets only about six or seven hours of sleep per night.

Get help. Be cautious if you feel sad all the time and the feeling won’t go away.5. Talk to an adult who you trust or get help from a doctor.

A. Eat more healthful foods.

B. Choose different foods in season.

C. Don’t be so busy that you get run-down.

D. Those people sometimes feel sad for no reason.

During the last twenty years there has been increasing concern with the quality of the environment. Along with air and water pollutions, noises pollution has been recognized as a serious pollutant. As noise levels have risen, the effects of noise have become more apparent.

Noise is defined as "unwanted sound". Causes of noise pollution include traffic, aircraft, rock bands, barking dogs, televisions, garbage trucks, and noise from neighbors, voices, alarms, and watercrafts. Studies show that over forty percent of Americans are disturbed at home or lose sleep because of noise pollution.

Noise has bad effects on people and the environment. Noise causes hearing loss, interferes (妨碍) with human activities at home and work, and is in various ways dangerous to people's health and well being.

When we think, talk, listen to music, or sleep, we need quiet. Even low levels of noise can be annoying or frustrating. Sudden increases in volume can make sounds annoying. The quieter the background is, the more penetrating a noise can be.

Noise can also make instructions or warning unclear, resulting in accidents. Louder noise bursts can be more disruptive (破坏性).Continued stress can lead to high blood pressure, which is the major cause of some diseases.

Long exposure to noise levels above eight-five decibels (分贝) can damage inner cells and lead to hearing loss. Noise can result in the involuntary fear response and can cause adrenaline (肾上腺素) to be pumped into the bloodstream, the heart rate to quicken, muscles to tense, breathing to increase, and the digestive system to slow down.

Local government has the responsibility to fight noise pollution. For example, it can regulate the speed of trains through their community. On the other hand, a responsible citizen will never make noise pollution wherever he is.

1. How many kinds of environmental pollution are mentioned in the text?

A. Two                  B. Three             C. Four            D. Five

2.According to the text, noise pollution may be caused by ________.

A. parties and meetings                      B. zoos and theaters

C. schools and factories                     D. vehicles and animals

3.What does the underlined word "penetrating" in paragraph 4 mean?

A. High and exciting                         B. Sharp and shocking

C. Loud and unpleasant                       D. Clear and comfortable

4.In the last paragraph, the writer suggests that ________.

A. individuals and government should work together to reduce noise pollution

B. the government should offer it's people better education on noise pollution

C. the government should be responsible for noise pollution

D. people who make noise pollution should be punished

5.Which of the following is not related to noise pollution?

A. hearing loss                              B. speeding the digestive system

C. high blood pressure                      D. accidents

There has been a lot of such news lately. As far as the problems with today's schools are concerned, we can go back to how our culture has evolved.

In general, our culture, as represented in the media, gets excited by famous stars, and stresses that it's what you have, not what you are, that counts. Parents are　 encouraged to be away from even very small children for most of the day. Too many people vote for politicians who would rather cut school funding than stop tax cuts for the wealthy. All contribute greatly to the problems of educating our children.

Today's teachers have to deal with a culture that is vastly different than in the past. They report that there is, among more children than ever, a lack of motivation, no drive to succeed or even try. In the media, the role models that boys see mostly consist of men in comedies and other shows, who are rude and often extremely childish; self-centered overpaid athletes; men in movies, television or video games, who are violent and powerful. As Leonard Sax wrote in Boys Adrift, "Teenage boys are looking for models of mature adulthood, but we no longer make any collective effort to provide such models."

Girls are attacked not only with such annoying images of males, but also with women who are extremely materialistic.

In such a cultural environment, it is more important than ever to have responsible parents who are devoted to their children and see to it as their duty to model for them and raise them with high standards of honesty and responsibility. They need to care enough to see that their children are not attacked with the rubbish that comes from movie, television and computer screens.

In today's culture, they are basically alone in this effort since, unfortunately, so much is working against them. Until we, as a culture, face the truth about ourselves- that we are not providing adequately for a great many of our children, as Jim Taylor titled his book "Your Children are Under Attack”。

1.What does "such news" in the beginning most probably involve?

A.Cultural evolution. B.Financial risk from tax cuts.

C.Problems in education. D.Social influence of the media.

2.What does today's culture bring to the children?

A.Narrow access to entertainment. B.Poor social abilities.

C.Few materialistic models. D.Too much negative effect.

3.What do parents have to do in today's culture?

A.Find more models for their children.

B.Keep their kids from the bad effect of the media.

C.Forbid their children to use computers.

D.Encourage their children to stay at school.

4.What is the author's attitude towards today's culture?

A.Indifferent. B.Ambiguous.

C.Dissatisfied. D.Approving.
