2．The journalist has already interviewed a lot of famous people．（改為否定句）
The journalisthasn't interviewed many famous peopleyet．

分析 這個新聞記者已經采訪了許多名人．
這個新聞記者還沒有采訪許多名人．

解答 答案：hasn't，yet．原句是現(xiàn)在完成時have/has+過去分詞，否定句是在助動詞have或has后加上not，這里是has加上not構成hasn't，already是放在肯定句中，否定句中需用yet，放句末，故答案是hasn't，yet．

點評 含有be動詞，情態(tài)動詞或者助動詞have/has的句子轉化成否定時在其后面加上not，一般實意動詞的否定式，通常應根據(jù)不同時態(tài)和人稱在實意動詞之前加don't，doesn't，didn't等

10．People sometimes say，"It's raining cats and dogs!"when there is a heavy rain．Nobody has ever really seen cats and dogs falling from the sky，but there have been many reports of other strange things"raining"down．In 1956，the people of a town in the USA saw a small blackcloud in the sky．It started to rain from the cloud normally，but only in a small area．The cloud then turned white，and fish started to fall to the ground．Most of them were still alive．
      During a storm in July 1901，in Minneapolis，people heard something falling from the sky that did not sound like rain．When they went outside，they found all types of frogs covering four streets．
     There are other reports of strange"rains"failing from the sky including worms，insects and snakes．
      Can these strange"rains"be explained by science？Scientists usually say that a tornado （龍卷風） has picked up the animals from a river or ocean，carried them for miles，and then dropped them somewhere else．But this does not completely explain all of them．On May 15，1890，in Italy，there was a rain of blood--birds'blood．Scientists said that flying birds must have been torn（撕碎） to pieces by strong winds．But if so，why did only their blood fall from the sky，and not other parts of their bodies？And anyway，there were no strong winds that day!
