Gold is one of the rarest materials on Earth and has always been considered a valuable and precious resource. It's very likely that someone in your family owns something made of gold, especially since China is one of the world's biggest buyers of gold jewellery. It's even in our smartphones - they contain parts made from this expensive material.

But where does this beautiful metal actually come from? The answer: outer space.

This August, Chinese scientists became the first in the world to witness gravitational waves（引力波）caused by the collision of neutron (中子）stars, reported Xinhua News Agency.

The sight was witnessed at China's Kunlun Antarctic Station at the South Pole, and Insight, China’s first X-ray astronomical satellite, also contributed to the discovery.

Although collisions of black holes have been recorded before, this was the first time that two neutron stars were known to have collided. It's believed that such collisions lead to huge explosions of energy, and even to the creation of precious metals such as gold and silver.

“The collision of neutron stars is like a very large gold factory in the universe,” Jin Zhiping，a researcher at the Purple Mountain Observatory of the Chinese Academy of Sciences, told Xinhua.

According to an article published by space.com, scientists have long believed gold and other materials are created in this way, but it wasn't until the recent collision that their theory was confirmed.

“The origin of the really heaviest chemical elements in the universe had confused the scientific community for quite a long time,” Hans-Thomas Janka, a senior scientist at the Max Planck Institute for Astrophysics in Germany, said in a news release. “Now, we have the first observational proof for neutron star mergers(合并) as sources.”

Indeed, the recently observed collision is thought to have produced an amount of gold that would weigh 10 times more than Earth, according to New Scientist

Don’t expect to be showered in gold any time soon, however. The collision actually took place 130 million years ago, taking all that time for the event's light to reach Earth.

But at least if you want to see a piece of space up close, all you have to do is to look at the ring on your mom's finger - or the smartphone in your pocket.

1.What's the author's purpose of writing the first two paragraphs?

A.To emphasize the rareness of gold.

B.To list some uses of gold in daily life.

C.To explain the reasons for the popularity of gold.

D.To interest readers about the source of gold.

2.What would the collision of neutron stars lead to according to Xinhua?

A.The creation of black holes.

B.The death of the stars.

C.The disappearance of gravitational waves.

D.The creation of gold.

3.What’s the text mainly about?

A.China’s Kunlun Antarctic Station does research into gold.

B.Collisions between two neutron stars result in gold

C.Collisions contribute to the discovery.

D.Gold is considered a valuable and precious rescource.

4.What can we learn from the article?

A.The amount of gold produced by the collision was very small.

B.The collision was the largest reported in history.

C.China played a big role in the new discovery.

D.The collision took place 130 years ago.

Nuclear energy has always been controversial. But since the tsunami and nuclear disaster in Fukushima(Japan) in 2011, the issue is back in the headlines. And the world is divided—some countries are planning more nuclear plants, while others have promised to shut theirs down.

After Fukushima, Germany decided to switch off all its nuclear plants by 2022. __1.__ In fact, almost 80% of France's electricity comes from nuclear power, the highest percentage in the world. And in the US, the Obama administration said it “continues to support the expansion of nuclear power, despite the crisis in Japan.”

Nuclear supporters claim nuclear power can help the environment. _2._ So, pro­nuclear countries argue that nuclear power allows them to generate energy without contributing to climate change. Britain's chief scientific adviser(John Beddington) supports this view.

Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind power may be clean, but they're expensive; and right now, they require a lot of investment. __3._ So, while many people may prefer their energy to come from a renewable source, not so many are prepared to pay higher energy bills.

__4._ For a start, nuclear waste is very difficult to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there were several high­profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands of people.

The nuclear energy issue is very complex. _5._ As a Japanese commentator recently said, “It's been a bad year for the ‘nuclear village’， but I don't think they're down and out yet.” The battle continues.

A．And it doesn't look like it'll be resolved anytime soon.

B．The main argument against nuclear energy is that it isn't safe.

C．Nuclear power could only end the world instead of saving it!

D．Many people believe that they will benefit from the unclear energy.

E．Unlike fossil fuels, nuclear power doesn't create greenhouse gases.

Nuclear energy has always been controversial. But since the tsunami and nuclear disaster in Fukushima (Japan) last year the issue is back in the headlines. And the world is divided— some countries are planning more nuclear plants, while others have promised to shut theirs down.

After Fukushima, Germany decided to switch off all its nuclear plants by 2022. Switzerland and Italy are also phasing out nuclear power. But France and the United States remain staunch supporters of atomic energy. In fact, almost 80% of France’s electricity comes from nuclear power, the highest percentage in the world. And in the US, the Obama administration said it “continues to support the expansion of nuclear power, despite the crisis in Japan.”

Nuclear supporters claim nuclear power can help the environment. Unlike fossil fuels, nuclear power doesn’t create greenhouse gases. So, pro-nuclear countries argue that nuclear power allows them to generate energy without contributing to climate change. Britain’s chief scientific adviser (John Beddington) supports this view. He recently said that the world doesn’t have the luxury of ignoring nuclear energy.

Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind power may be clean, but they’re expensive; and right now, they require a lot of investment. This higher cost of using “green energy” is usually passed onto the consumer. So, while many people may prefer their energy to come from a renewable source, not so many are prepared to pay higher energy bills. This is of particular concern while the world economy is in such bad shape.

The main argument against nuclear energy is that it isn’t safe. For a start, nuclear waste is very difficult to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there were several high-profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in the Ukraine.

1.Which of the following may NOT be the advantage of nuclear energy over other energy sources?

高三英语阅读理解极难题查看答案及解析

It has always been thought that alcohol causes people to put on weight because it contains a lot of sugar, but new research suggests a glass a day cold form part of a diet. Looking at past studies they found that, while heavy drinkers do put on weight; those who drink in moderation can actually lose weight.

A spokesman for the research team at Navarro University in Spain says, “Light to moderate alcohol intake, especially of wine, may be more likely to protect against, rather than promote, weight gain.” The International Scientific Forum on Alcohol research reviewed the findings and agreed with most of the conclusions, particularly that data do not clearly indicate if moderate drinking increases weight.

Boston University’s Dr. Harvey Finkel found that the biologic mechanisms(生物学机制) relating alcohol to changes in body weight are not properly understood. His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes(糖尿病), which relate to increasing obesity. Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.

The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat, and that this process could explain the differences in its effects from those of other foods. They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks, taking into consideration drinking patterns and including the past tendency of participants to gain weight.

For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese. What’s more, a study three years ago suggested that resveratrol, a compound present in grapes and red wine destroys fat cells.

1.The passage is mainly for those_________.

A. who produce wine

B. who have a drinking habit

C. who go on a diet

D. who are eager to lose weight

2.The underlined phrase“ in moderation” in the first paragraph means _________.

A. excitedly        B. carefully        C. frequently        D. properly

3.What can we learn from the passage?

A. Current data clearly show that moderate drinking increases weight.

B. Resveratrol is proved to increase the risk of becoming fat.

C. The research found moderate drinking has a strong protective effect.

D. The specific roles of different types of alcoholic drinks are very clear.

4.What is most likely to be discussed in the paragraph that follows?

A. How to do some easy experiments.

B. How to reduce the calories contained in wine.

C. How to prove the finding mentioned above.

D. How to make wine in a healthy way.
