7. The man showed us so heavy a stone         . (lift)

那人向我們展示了如此重的石頭,沒人可以搬起它。

7. as no man/nobody could lift/that nobody could/ was able to lift it先行詞前有so修飾時(shí),引導(dǎo)定語(yǔ)從句的引導(dǎo)詞應(yīng)用as;as在從句中充當(dāng)邏輯賓語(yǔ),因此,此處切忌用it。若用that引導(dǎo),則是一個(gè)結(jié)果狀語(yǔ)從句,it不可省略。

科目:高中英語(yǔ) 來(lái)源: 題型:

   Warmer sea temperatures could worsen the widespread destruction of coral reefs that hit the Caribbean in 2005,scientists fear.

  In the waters around the US Virgin Islands,as much as 40 percent of coral died in some reefs last year,and the coral that survived probably isn't healthy enough to survive another hot summer,said Caroline Rogers,a US Geological Survey biologist.

Reefs are vital habitat for fish,lobsters and other sea life that feed and breed in the sheltered waters. The reefs also change storm waves that might otherwise wash away the beaches that are at the heart of the region's multibilliondollar tourism industry.

  "You don't know how scary it looks down there," said Zandy Starr,who monitors coral and sea turtles in St. Croix's national parks. "All of us thought that by now,with all the cooler temperatures in January and February,we would have seen recovery,but they're still sick."

  Glassy,calm seas have permitted coralkilling ultraviolet (紫外線的) rays to access to the ocean floor,warming water temperatures and making the fragile (易碎的) undersea life more sensitive to disease,Starr said.

Scientists haven't pinpointed (準(zhǔn)確地說(shuō)出) what caused coral to become sick or led to the warm water,which stresses coral and makes it more susceptible (敏感的) to disease. They can't say whether global warming is a factor.

  "We don't really have the data. You need a record over decades. There's a lot of research that needs to happen”,said Alberto Sabat,a biology professor at the University of Puerto Rico.

But the trend of warmer waters isn't limited to the Caribbean. The National Oceanic and Atmosphere Administration said waters were warmer than usual in the South Pacific,mid-Atlantic and Indian Ocean in mid-April.

  Rogers said coral grew far better after hurricanes that devastated (摧毀) the US Virgin Islands in 1989 and 1995 because the storms cooled the sea,allowing reefs to recover relatively quickly from damage.

Rising temperatures appear to be "something new that the corals aren't used to," said Tyler Smith,a marine researcher at the University of the Virgin Islands.

The scientists worry that the problem is being overlooked,

  "People just don't know that much about coral because it's underwater. If 40 percent of the trees ill one of our national parks died,people would take notice”,Rogers said.
