【推荐2】阅读下列短文，从每题所给的四个选项(A、B、C和D)中, 选出最佳选项。
According to the US government, wind farms off the Pacific coast could produce 900 gigawatts of electricity every year．Unfortunately, the water there is far too deep for even the tallest windmills to touch bottom．An experiment under way off the coast of Norway, however, could help put them anywhere．
The project, called Hywind, is the world’s first large-scale deepwater wind turbine (涡轮发电机)．Although it uses a fairly standard 152-ton, 2．3-megawatt turbine, Hywind represents totally new technology．The turbine will be fixed 213 feet above the water on a floating spar, a technology Hywind’s creator, the Norwegian company StatoilHydro, has developed recently．The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cables ; these will keep the spar stable and prevent the turbine from moving up and down in the waves．Hywind’s stability in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power．If all goes according to the plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September．
To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean．To make that turbine heavier, the whole spar’s center of gravity must be moved much closer to the ocean’s surface．To do that, the company plans to design a new kind of wind turbine, one whose gearbox (变速箱) sits at sea level rather than behind the blades．
Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large．Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted．Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection．If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available．
1. The Hywind project uses totally new technology to ensure the stability of_________.

A．the cables which tie the spar to the ocean floor

B．the spar which is floating in deep-sea water

C．the blades driven by strong and steady sea wind

【推荐1】Coral reefs(珊瑚礁) are a unique ocean ecosystem consisting of rocky structures mainly formed by coral animals and some other ocean life. Despite only covering 0. 2 percent of the ocean floor, coral reefs support at least 25 percent of marine species, as well as providing food and economic security for hundreds of millions of people.

However, coral reefs across the world are under threat. Warmer oceans can cause the coral bleaching(漂白). It happens when the corals lose colored algae(海藻) living in their bodies and turn completely white. Without the algae, the corals lose their main food source and can die. In addition, as oceans become more acidic(酸性的) from absorbing CO₂, corals in acidic conditions become weak in forming reefs.

In 2021, the United Nations reported a 14 percent loss of corals across the world largely from rising sea temperatures in the previous 13 years. Australia declared mass bleaching events in 2022 across large parts of the Great Barrier Reef, four times since 2016. Data from the Philippines showed higher than usual ocean temperatures between 2015 and 2017 had caused a serious three-year bleaching events in reefs across the planet.

Scientists have been cooperating to see how coral reefs can be protected. Thankfully, they find those coral reefs in the hot parts of the globe are the worst affected. They contain corals with better heat resistance. So their research focus on finding genes(基因) for heat tolerance so that they can be passed on to future generations. Biologists also mix corals that are more resilient to higher temperatures with those that are not and the resulting generation has a better chance of survival.

Ultimately, scientists add that without a serious decline in greenhouse gas, 99 percent of the world’s coral reefs will be gone by the end of the century. There is a limit to how quickly corals can adapt warm climate, but if temperatures rise rapidly, then extinction is certain.

【推荐2】The spread of Western   eating habits around the world is bad for human nealth and the environment.These findings come from a new report in the journal Nature.

David Tillman, a professor of ecology at the University of Minnesota, America, examined information from 100 countries to identify what people ate and how diet affected health. He noted a movement beginning in the 1960s. He found that as nations mdustriaHzed(工业化),population increased and earnings rose, more people began to adopt what has been called the Western diet.

The Western diet is high in sugar, fat, oil and meat. By eating these foods, people began to get fatter and sicker. David Tillman says overweight people are at greater risk for non-infectious diseases like diabetes (糖尿病）and heart disease.

Unfortunately, when people become industrialized, if they adopt this Western diet, they are going to have these health problems, especially in developing countries in Asia, China is an example where the number of diabetes cases has been jumping from less than one percent to 10 percent of the population as they began to industrialize over a 20，year period, And that is happening all across the world, in Mexico in Nigeria and so on.

And, a diet bad for human beings, is also bad for the environment As the world's population grows, more forests and tropical (热带的）areas will become farmland for crops or grasslands for cattle. We are likely to have more greenhouse gas in the future from agriculture than that coming out of all froms of transportation right now.

Mr．Tillman calls the link between diet，the environment and human health，"a dilemma"，a problem offering a difficult choice. He says one possibte setttemenf is leaving the behind.

A．diet, the environment and human health are closely connected

B．the Western diet is the only choice as the nation industrializes

C．people in tropical areas are more likely to have heart disease

D．traditional diets are more balanced than the Western diet

3. We can infer from the passage that .

A．industrialization contributes to the spread of the Western diet

B．overweight people are at higher risk of infectious diseases

C．the examined information comes from developing countries

D．Nigeria has the largest number of diabetes cases

4. The main purpose of the passage is to .

A．call on us to protect the environment

B．warn us of the danger of the Western diet

C．remind us of the importance of health

D．advise us to have a balanced diet

【推荐3】People from East Asia tend to have more difficulties than those from Europe in distinguishing facial expressions and a new report published online in Current Biology explains why.

Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly (均匀的) across a face as Westerners do, Easterners fix their attention on the eyes.

“We show that Easterners and Westerners look at different face features to read facial expressions,” Jack said. “Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and overlook the mouth.”

According to Jack and her colleagues, the discovery shows that human communication of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to reliably convey emotion in cross-cultural situations.

The researchers studied cultural differences in the recognition of facial expressions by recording the eye movements of 13 Western Caucasian and 13 East Asian people while they observed pictures of expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral. They compared how accurately participants read those facial expressions using their particular eye movement strategies.

It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than Westerners did. “The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions,” Jack said. “Our data suggest that whereas Westerners use the whole face to convey emotion. Easterners use the eyes more and mouth less.”

In short, the data show that facial expressions are not universal signals of human emotion. From here on, examining how cultural factors have diversified these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.

A．They do translation more successfully.	B．They study the mouth more frequently.
C．They examine the eyes more attentively.	D．They read facial expressions more correctly.

4. What can be a suitable title for the text?

A．The Eye as the Window to the Soul	B．Cultural Differences in Reading Emotions
