Most parts of China have access to sufficient supplies of fresh water for drinking. But fresh water can be in short supply in many regions of the world such as Saudi Arabia, where there are limited water resources. As the world population continues to grow, shortages of fresh water will occur more often and the need for additional water supplies will become critical. Some may ask, “Since the ocean covers more than 70 percent of the Earth, why not just get drinking water from the ocean?”

To turn seawater into fresh water we need to remove the salt in seawater, that is, to desalinate seawater. The problem is that the desalination of water requires a lot of energy. Salt dissolves very easily in water, forming strong chemical bonds, and those bonds are difficult to break. The energy and technology to desalinate water are both expensive, and this means that desalinating water can be costly.

There are environmental costs of desalination as well. Sea life can get sucked into desalination plants, killing small ocean creatures like baby fish, upsetting the food chain. Also, there is problem of what to do with the separated salt, which is left over as a very concentrated salty water. Pumping this super-salty water back into the ocean can harm local sea life. Reducing these impacts is possible, but it adds to the costs.

Despite the economic and environmental hurdles, desalination is becoming increasingly attractive as human beings are using up fresh water from other sources. At present desalinating seawater is the only practical way to provide water to growing populations in rural areas of the Middle East and North Africa. Therefore, the race is on to find a cheaper, cleaner, and more energy-efficient way of desalinating seawater, and promising new finding are being reported.

1. What is the second paragraph mainly about?
A.The high cost of desalinating seawater.
B.The major chemical characteristics of seawater.
C.The urgent need to turn seawater into fresh water.
D.The amount of energy produced in the desalination of seawater.

文章大意:本文是说明文。这篇文章主要介绍了人类与野生动物之间的相互合作,特别是人类与一种叫做greater honeyguide的非洲小鸟之间的合作关系。

【推荐1】Mutual cooperation in which humans cooperate with wild animals is extremely rare. One such system involves the greater honeyguide, a small African bird that leads humans to sources of honey. Once a nest is found, the human honey hunters break into it to obtain honey and bee worms, and the birds benefit from consuming beeswax in the now-exposed honey comb. Both the birds and the humans use specialized sounds to communicate their availability to participate in this cooperative interaction.

The two areas studied by Spottiswoode and Wood are northern Mozambique, where the honey hunters are from the Yao cultural group, and northern Tanzania, where the honey hunters are from the Hadza culture. The Yao communicate with honeyguides using a short and high-pitched sound followed by a low sound ”brrrrhm“, whereas the Hadza use a melodic whistle. Thus, signal and response both vary geographically.

Spotiswoode and Wood propose that the geographic variation they have identified in this mutualism is the product of cultural codevelopment. To qualify as cultural, the cooperative behaviors would have to be acquired through social learning from individuals of the same species. Social learning, however, is less of a given on the honeyguide side. Instead, what is required of honeyguides is another form of vocal learning - comprehension learning — in which the meaning of a signal is learned. Comprehension learning is common in birds. Whether social learning is involved, however, is not so, obvious.

Honeyguides put in considerable effort helping their human partners find food and are faithfully rewarded by being given food in return. In some human cultures, honey hunters purposefully leave out honeycomb to reward honeyeaters, but in others the hunters go, to great length to deny the birds any reward, by collecting, burying, or burning any honeycomb exposed when they destroy a nest. The reason given for these acts is that keeping the birds hungry causes them to continue guiding.

A promising question for future research is whether geographic differences in human cultural preferences for rewarding or not rewarding honeyguides affect the preferences of individual birds for guiding versus taking advantage of the guiding of others.

1. What is the purpose of mentioning the two areas in Paragraph 2?
A.To show that honey hunting is very popular in their culture.
B.To explain that communication methods differ in geography.
C.To illustrate the differences between the Yao and the Hadza.
D.To show that birds can understand various human cultures.
2. Why do some hunters refuse to give honeyguides any prizes?
A.To let them realize human’s power.
B.To make them keep providing help.
C.To cause them to burn honeycomb.
D.To use the honeycomb themselves.
3. What can be inferred about the relationship between humans and honeyguides?
A.Honeyguides have already had strong skills to learn from society.
B.Honeyguides have a genetic tendency to guide humans for honey.
C.Humans and honeyguides have a mutually beneficial relationship.
D.Human honey hunters will lose their jobs without honeyguides.
4. What is likely to be discussed in the following paragraph?
A.The impact of human cultural preferences on honeyguide behavior.
B.The further study on the cultural differences in human preferences.
C.The ecologically rewarding consequences of honeyguide behavior.
D.The influence of honeyguide behavior on human cultural practices.

文章大意:文章是一篇新闻报道。讲述3亿人参加动物收养日,推动人们对流浪动物的收养,唤起人们关注动物的意识,帮助流浪动物找到有爱的家。

【推荐2】A total of 34 Chinese cities with a combined population of nearly 300 million took park in a pet adoption day at the weekend, promoting the adoption of rescued stray (流浪的) animals.

The live broadcast of China Pet Adoption Day events in Shanghai, Beijing, Chengdu, Guangzhou, Hangzhou, Nanjin, Qingdao, Tianjin and Xi’an was watched by 562,000 people.

From Urumqi in the far northwest to Fuzhou on the southeast coast, people gathered to raise awareness of animal care and to help stray find loving homes.

Sun Quanhui, manager and senior adviser of World Animal Protection, said, “Planet Earth is not only home to humanity but also a home that we share with other animals. It is mankind’s duty and important to treat animals kindly in a civilized society.”

As China’s population becomes richer, pet ownership has increased rapidly, but problems, such as pet abandonment and cruelty, are also growing.

In recent years, more and more adoption events have taken place all over the country, which indicates an awakening of the Chinese public consciousness to animal protection.

“Adopting a pet instead of buying one has been gaining a wider acceptance.”

American Edward Dumpe, who has been working on designs for stray animal shelters in Beijing, said, “It surely sounds super sweet and I have no doubt that it must have been the result of great efforts.”

“I think it is a good step in the right direction, and should be taken as evidence that Chinese society is becoming more aware of stray animals who should be taken care of and treated with respect.”

In real life, “Rabbit-eating Carrot” is fashion designer who has created clothes embroidered with slogans such has “Please adopt a pet” and images of her cats, with all earnings going to the Qiming Small Animal Protection Center in Sichuan Province.

“I didn’t know that there were events like this in China. This is fantastic. Impressive.” Said George Philippe, a french living in Beijing and father of two, at an event in the capital.

1. What is the aim of live broadcast of China Pet Adoption Day event?
A.To improve the awareness of animal adoption
B.To attract more attention to the Event
C.To encourage more and more people to take part in the live broadcast.
D.To introduce some useful western practice of animal adoption
2. What will be a problem with the increase of pet ownership?
A.More pets are in great need in China
B.There is not enough related service for pets and their owners
C.Some pets need to be given large space to enjoy themselves
D.Some people throw their old or disabled pets away
3. From the story of “Rabbit-eating Carrot”, which word can be used to describe her?
A.Smart and cuteB.Creative and independent
C.Fashionable and kind-heartedD.Wealthy and healthy
4. What is the best title for the passage?

文章大意:本文是一篇说明文。相关研究表明,犀牛因不断升高的气温将于2085年灭绝。研究者建议公园的管理人员应该开始规划如何保护犀牛。

【推荐3】The African continent has seen its average monthly temperatures rise by 0.5 — 2 degrees Celsius over the past century, with up to another two degrees of warming projected for the next 100 years. The changing climate will break historical rainfall patterns, but which of these, temperature or rainfall, will have the most impact on a species, like rhinos (犀牛) ?

“Generally speaking, most, if not all, species will. in one way or another, be affected by the changing climate,” says lead author Hlelowenkhosi S. Mamba, who completed this research. It is therefore important to catch tendency (趋势) and model futures for some of the world’s weakest species. It can help prepare to reduce climate change’s effects, hence reducing global biodiversity losses.

To understand how our changing climate will affect rhino populations, Mamba and Timothy Randhir, professor of environmental protection, focused their efforts on the five large national parks that are home to most of the rhinos.

Mamba and Randhir then modeled two scenes for each of the parks: the IPCC’s high-emissions (排放) scenes and a more moderate (适度的) emissions scenes. They projected temperature and rainfall for each of the scenes out to 2055 and 2085 to arrive at a possibility that each park would remain suitable for the rhinos.

Nearly every park will become increasingly drier as emissions increase. This is all very bad news for the rhinos, because the team also found that, though the change in rainfall will not be most suitable for the rhinos, the changes in temperature are greater than what the species can bear.

“The temperature conditions in all study parks will become increasingly unsuitable for the species. And under the high-emissions scenes, the possibility of occurrence of the species falls to zero by 2085,” the authors write.

But to be forewarned is to be prepared in advance. “We propose that park managers think now about increasing water supplies, tree cover, watching for stress and planning to allow rhinos to move from one place to another place as the world warms,” says Randhir.

1. Why does the author ask a question in Paragraph 1?
A.To show an evidence.B.To stress the main idea.
C.To lead in the topic.D.To offer some background.
2. What does the second paragraph mainly focus on?
A.The means of the research.B.The content of the research.
C.The process of the research.D.The significance of the research.
3. What can we know about the research from the text?
A.Changes in rainfall have a greater effect on rhinos.B.Each park will have no rhinos in 2055.
C.Changes in temperature affect rhinos more.D.Each park will be warmer by 4. 5℃ in 2085.
4. What does Randhir mean in the last paragraph?
A.Rhinos are better suited to natural growth.B.Rhinos are in great danger in the five parks.
C.Park managers should plan to protect rhinos.D.Park managers must pay more attention to nature.
