【正文】 家更喜歡在海洋中尋找流星是因為他們可能會發(fā)現(xiàn)更大的巖石顆粒。這些物體是在美國太平洋沿岸發(fā)現(xiàn)的。D.Stress the importance of the event.B.Offer clues for the search.D.They may find bigger rock particles.C.They can find meteors more easily.D.Business value of meteors.C.To examine creatures of the explored ocean.（2）What mainly caused the start of the search in the sea? A.To study unexplored places of the ocean.B. The objects recovered from the bottom of the sea likely came from the recent explosion for two main reasons. First, meteorite particles are basically made of glassy materials that do not tend to last long in seawater. Secondly, they came from what looked like a small hole on the seafloor. Some evidence shows that they came from something that fell.（1）What is the current goal of the crew of the Ocean Exploration Trust? A. The search was launched after US government weather stations observed a large meteorite exploding some months ago. The explosion lit up the sky and sent the rock particles to the earth. The meteorite fall was the largest recorded over the United States in at least 20years. The team includes scientists from NASA, the Olympic Coast National Marine Sanctuary and the University of Washington. The scientists examined what they believe were two small meteorite fragments. Further testing is needed before they can confirm that the material came from the explosion. Scientists have found what they believe are pieces of a meteor(流星)that fell to the earth last year. The objects were discovered off the coast of the United States in the Pacific Ocean. 【點評】本題考點涉及細節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇科研類閱讀，要求考生準確捕捉細節(jié)信息，同時根據(jù)上下文進行邏輯推理，從而選出正確答案。由此可知。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。 （3）考查細節(jié)理解。由此推斷出劃線詞所在的句子意思是我們所吃的食物給環(huán)境帶來了巨大代價。caused greenhouse gas emissions.
