Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy．Apart from this，studies are being carried out to harness(利用) usable wind energy produced by man-made technologies．

One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train，which produces fierce wind that can be transformed into electricity．

According to Pradhan’s proposal，with a few small improvements in existing trains running in Mumbai，the largest city in India，at least 10，000 megawatts(兆瓦) of electricity could be harvested each day．

Building on this principle，designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device(装置) called T-Box that harnesses wind energy from speeding trains．

T-Box can be placed within the railway tracks．It is half-buried underground between the concrete sleepers(水泥枕木)，which does not disturb the normal train operating at all．According to Yanko，around 150 T-Boxes can be fitted along a 1，000-meter railway track．

A train running at a speed of 200 kph can produce winds blowing at 15 miles a second．Based on this calculation，150 T-Boxes can produce 2．6 KWH of electricity per day．The T-Box’s design won a silver medal in last year’s Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei，Taiwan Province．

Though the figures look impressive，it is important to remember that the design is still at a conceptual stage and hasn’t taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance(维护) of the device．

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino. The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.

One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe（津巴布韦）, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.

The scientists wrote about their recent work in the publication Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.

1.El Nino is known as ________.

A. the changing of the weather in southern Africa

B. the weather which brings drought (旱灾) to Africa

C. the warming of waters in the Pacific Ocean

D. the weather phenomenon that brings heavy rains to Africa

2.Scientists study El Nino in order that ________.

A. they can put all this information into their computers

B. they can tell why Zimbabwe has little or no rain

C. they can do some research work in this field

D. they can provide a kind of early warning to the place that will suffer from drought

3.Which of the following is TRUE according to the passage?

A. Scientists come to understand how El Nino appears.

B. Three scientists from the USA work on this subject.

C. El Nino has something to do with Zimbabwe’s poor crops.

D. Southern Africa suffered a serious drought and many people died from hunger.

Around the world, eggs have been a breakfast staple（重要部分）for all good reasons. After all, an egg is a storehouse of vital nutrients, making it an essential part of a healthy diet. And for those of you who are afraid of having this power food because you're worried that it will add to your weight, remember, one egg contains about 80 calories and about five grams of fat. Hence, smart consumption is a far healthier option.

Eggs are a well-known rich source of protein — an important building block of bones, muscles, skin, and blood. The body uses protein to build and repair tissues as well as making other body chemicals. Unfortunately, unlike fat and carbohydrates(碳水化合物), the body does not store protein, and therefore has no reservoir to draw on when it needs a new supply. Thus eggs are the perfect sources and a smart food choice for those who reduce their intake of carbohydrates in a bit to lose extra weight.

Another important nutrient you'll find abundantly in egg white is riboflavin or Vitamin B2. And for all of you wondering what's the benefit of this nutrient, Riboflavin is a water-soluble(水溶性) vitamin which is involved in vital processes in the body and is necessary for normal cell function, growth, and energy production.

The yolk, which many of us avoid out of fear, is actually a very healthy food, if consumed in moderation(适度). Mainly fat, the yolk contains 1.33 gm of cholesterol（胆固醇） per 100 gms and is a rich source of vitamin A, B vitamins, calcium, phosphorous(磷) and iron. Incidentally, the iron found in the yolk is easily digested in the body. According to nutrition experts, one can eat one whole egg every day without harming one's cholesterol and other blood-fat levels. But for those who crave for more eggs, you can reduce fat by having one whole egg and the whites of the rest of the eggs.

1.Eggs are regarded as important in breakfast because__________.

A. it is a custom to have eggs in the breakfast.

B. they are sold at a low price.

C. they are high in calories and low in fat.

D. they can provide people with many nutrients.

2.When our body is short of protein, we may____________.

A. feel tired and sleepy.

B. feel discomfort in our legs.

C. get tired of eating eggs.

D. be eager for other chemicals.

3.Which of the following is true about protein?         .

A. It can’t be stored in the body.

B. Fat can be changed into protein.

C. It is a kind of carbohydrate.

D. Our body can only get protein from eggs.

4.We can infer from the last paragraph that____________.

A. the author suggests we only eat the whites of eggs.

B. eating enough yolk can reduce cholesterol in the body.

C. iron and phosphorous in the yolk are difficult to digest.

D. high blood-fat level can do harm to our health

Researchers around the world interested in uncovering complex human disorders, such as Alzheimer’s disease, could soon have access to cloned monkeys with genomes that have been edited to display these conditions in China.

On 24 January, scientists at the Institute of Neuroscience (ION) in Shanghai reported that they had used gene-editing to disable a gene in monkeys that is crucial to their sleep- wake cycle. The scientists then cloned one of those monkeys to produce five primates (灵 长目动物)with almost identical (相同的) genes. It is the first time that researchers have cloned a gene-edited monkey.

Primates are the best animal model for studying higher cognitive (认知的)functions and brain disorders in humans, says neuroscientist Mu-ming Poo, ION’S director and co-founder of the new 720 million yuan (US$106 million) centre. The advantage of creating cloned monkeys is that it reduces the number of animals needed for certain types of experiments, such as testing whether a drug works.

But some scientists think that experiments using monkeys should be a last approach because of their higher levels of cognition. Mitchell Lazar, who studies metabolic disease at the University of Pennsylvania, says that some experiments in mice—for example, research into the genes behind human diseases—are equally appropriate scientifically as in primates. Research in mice is also more accepted by the public, and the animals are cheaper and quicker to produce. Lazar worries that if scientists have ready access to populations of gene-edited monkeys, they might use them for experiments when rodents (啮齿动物)would do.

Poo says that mice are not a good substitute for studying higher cognitive functions and brain disorders in humans. He argues that cloning will reduce the burden on monkeys by cutting the number used in labs. The ION follows strict international guidelines for animal research, he says.

Poo’s team will continue to study the effect of gene editing on their five cloned monkeys. The group disabled a gene, BMAL1, that has a crucial role in maintaining circadian rhythm (生理节奏)，the internal clock that helps a healthy sleep-wake cycle. In people, BMAL1 mutations have been linked to diabetes, hypertension and depression.

The monkeys with the disabled BMAL1 genes move more at night and sleep less overall. They also display psychosis-related symptoms, such as fear and anxiety, when put in unfamiliar environments.

The team ’ s next step is to look in detail at the neural (神经的)mechanisms that might create these problems. It will also take advantage of the genetically identical monkeys to hunt for diagnostic markers of circadian rhythm-related disorders and possible treatments.

1.Why were the genetically identical monkeys cloned?

A. To prove scientists’ innovation in cloning animals.

B. To study the rare characteristics of cloned monkeys.

C. To explore many possibilities for monkeys’ cognition.

D. To provide improved animal models of human diseases.

2.What does Mitchell Lazar think of cloning monkeys?

A. It is of little value.

B. It is of much practice.

C. It is hardly acceptable.

D. It is completely illegal.

3.From the passage we can know that Poo’s team will .

A. continue to disable a gene on the monkeys

B. try to clone more monkeys and edit their genes

C. find the similarities between humans and monkeys

D. determine the cause of sleep disorders and find cures

4.What’s the main idea of the passage?

A. Chinese effort to clone gene-edited monkeys kicks off.

B. Chinese dream to clone monkeys has finally come true.

C. Cloning monkeys is an important breakthrough in science.

D. Cloning gene-edited monkeys has caused some moral risks.

Trees around us are extremely important and have always been necessary for improving the human conditions. Our existing forests and trees we plant work to make a better world. 1.. Here is a short list of main reasons trees are necessary for improving our living conditions.

●Trees produce oxygen

2.. A leafy tree produces as much oxygen in a season as 10 people inhale in a year. What many people don't realize is that the forest also acts as a giant filter (过滤器) that cleans the air we breathe. Trees help clean the air by preventing airborne particles, reducing heat, and absorbing such pollutants.

●Trees clean the soil

The term phytoremediation is a fancy word for the absorption of dangerous chemicals and other pollutants that have entered the soil. 3.. Trees filter sewage and farm chemicals, reduce the effects of animal wastes, clean roadside spills and so on.

●Trees are carbon sinks

To produce its food, a tree absorbs and locks away carbon dioxide in the wood, roots and leaves. Carbon dioxide is a global warming suspect. 4.. This locking­up process “stores” carbon as wood and not as a “greenhouse” gas.

●5.

Trees block urban noise almost as effectively as stone walls. Trees, planted at strategic points in a neighborhood or around your house, can reduce major noises from freeways and airports.

A．We could not exist as we do if there were no trees

B．Trees help clean the sky

C．A forest is a carbon storage area that can lock up as much carbon as it produces

D．Trees control noise pollution

E．Man has been planting trees to make the planet a more beautiful world

F．The modern human community has other more practical reasons to admire and honor trees

G．Trees can either store harmful pollutants or change the pollutants into less harmful forms

In a major medical breakthrough, Tel Aviv University researchers have “printed” the world's first 3D vascularized (有血管的）engineered heart using a patient’s own cells and biological materials. Their findings were published on April IS in a study in Advanced Science.

“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” says Prof. Tal Dvir of Department of Materials Science and Engineering, who led the research for the study. “This heart is made from human cells and patient-specific biological materials. In our process, these materials serve as the bioinks, something made of sugars and proteins that can be used for 3D printing of complex tissue models，” Prof, Dvir says. “People managed to 3D print the structure of a heart in the past, but not with cells or with blood vessels (血管).Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future.”

According to Prof. Dvir，the use of “ native ” patient-specific materials is important to successfully engineering tissues and organs.

The researchers are now planning on culturing the printed hearts in the lab and “ teaching them to behave” like hearts, Prof. Dvir says. They then plan to transplant the 3D-printed heart in animal models.

“We need to develop the printed heart further，” he concludes. “The cells need to form a pumping ability ； they can currently contract (收缩），but we need them to work together. Our hope is that we will succeed and prove our method’s efficacy (功效)and usefulness. “Maybe, in ten years, there will be organ printers in the finest hospitals around the world，and these procedures will be conducted routinely. ”

1.What does Prof. Dvir think of an early 3D-printed heart?

A.It was highly practical. B.It was too expensive.

C.It was personalized. D.It was too simple.

2.What do we know about the latest 3D-printed heart?

A.It can be cultured in the lab.

B.It can match a patient perfectly.

C.It has been transplanted in animals.

D.It has been widely used in hospitals,

3.What is Prof, Dvir's attitude to the development of the printed heart?

A.Ambiguous. B.Positive.

C.Disapproving. D.Cautious.

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

A.To explain the basic principle of 3D technology.

B.To introduce a breakthrough of medical research.

C.To doubt the medical value of a new invention.

D.To prove the effectiveness of the new technology.
