高三英语单项填空中等难度题查看答案及解析
Something’s happening at the lowest point on our planet.
The Dead Sea, a salt lake bordered by Jordan to the east and Israel and Palestine to the west, is shrinking at an alarming rate - about 3. 3 feet per year, according to the environmentalist group Eco Peace Middle East. And human actions are largely to blame.
"It's not just like one country is punishing the Dead Sea: it's more like the whole area,” said photographer Moritz Kustner, who visited the area in February to work on his series "The Dying Dead Sea”.
The Dead Sea needs water from the other natural sources surrounding it, such as the Jordan River basin. But around the 1960s, some of the water sources it relied upon were diverted. Israel, for instance, built a pipeline during that time so it could supply water throughout the country.
Mineral extraction industries are another main reason the water levels are falling, experts say. The Dead Sea's minerals have been used as medicine and can often be found in cosmetics and other consumer products.
And then, of course, there's the Middle East's hot, dry climate, which makes it difficult for the lake to replenish itself. Last year, Israel and Jordan signed a $900 million deal in an effort to keep the Dead Sea's water levels stable. It includes building a canal from the Red Sea to the Dead Sea which would be able to not only supply water to Israel and Jordan but also to pump water into the Dead Sea.
But for now, Kustner shows us that the Dead Sea remains very much a place of interest, with people from all over the world going there to swim in its salty waters
The Dead Sea, known as the Salt Sea in the language of Hebrew, is one of the saltiest bodies of water in the world. And because of what has been happening over the years, the salt is only getting saltier.
1.How many reasons for the Dead Seas shrinking does the author mention in the text?

2.What can we learn about the Dead Sea 's minerals?
A.They have practical value.

3.What does the underlined word "replenish” in Paragraph 6 probably mean?
A.To clean something. B.To improve something.
C.To fill something again. D.To find something again.
4.What would be the best title for the text?

The wave of panic buying 抢盐风波
Many people in China rushed to store as much iodized salt(含碘食盐)as possible. This trend has led to grocery store shelves being ransacked over the past several days.
"I went looking for salt in the supermarket, stores and street markets, and it's all sold out."
It all stems from the rumor that iodized salt could help ward off radiation poisoning spreading from Japan's Fukushima Daiichi power plant. Consumers also worried that the nuclear plumes might spread to China by air and sea, contaminating food sources, including salt taken from the sea.
The wave of panic buying spread quickly throughout the country, driving up salt prices by five to ten fold(涨到五到十倍)in some cities.
Even regions rich in salt production, like Jiangxi Province face sudden shortages.
Local authorities have stepped in to stabilize the market. As well, state-owned salt companies have been urged to increase their supply.
Facing expanding market demand, distribution centers like this one in Beijing have taken extra measures to ensure they are well-prepared.
Wang Yun, Beijing Salt Industry Corporation, said, "Our storage reserves can guarantee a two-month supply for the Beijing market."
Measures are being taken to prevent panic buying. Health authorities and experts have begun informing the public that the rumor of salt's protection against radiation is "totally unfounded"(完全是无稽之谈). The public is being urged to be more rational when buying salt.

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can’t see black holes. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently from other ones.
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or “staff”, in an object.
Another kind of black hole is called “stellar”(星球黑洞). Its mass can be up to 20 times more than the mass of the sun. There may be many stellar mass black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way.
The largest black holes are called “supermassive”(超大质量黑洞). These black holes have masses that are more than one million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy has a mass equal to about four million suns and would fit inside a very large ball that could hold a few million Earths.
Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or falls apart. When this happens, it exploded part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.
A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting a black hole.
When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.
1.The gravity of a black hole may become so strong that light cannot get out when ____________.
A. the star is going to die
B. special tools are used on it
C. other stars come close to it
D. it is seen from the space telescopes
2.According to the passage, which of the following is NOT true?
A. A black hole can be very tiny but extremely heavy.
B. The gravity of a black hole holds all light in its center.
C. Scientists observe high-energy light through their own eyes.
D. Some small black holes came into being as early as the universe.
3.The underlined word “galaxy” in Paragraph 5 means __________.
A. a black hole B. the Milky Way
C. a series of stars D. a planet near the earth
4.What does the last sentence in Paragraph 5 suggest?
A. Neither the sun nor the earth is as heavy as a black hole.
B. There is a supermassive black hole at the center of the Milky Way.
C. The supermassive black hole had existed before the Milky Way was formed.
D. There is a reason why the large black holes are called “supermassive”.
5.The last two paragraph mainly focus on the question of _________.
A. what a black hole is
B. how black holes form
C. how big black holes are
D. how scientists know about black holes
