17．-Shall I lock the lab now before I go home？
-_____．I'll check it when I leave．（　�。�
A．Go aheadB．No problemC．No wayD．No bother

分析 --在我回家之前我要把門鎖好嗎？
--不用麻煩了．當(dāng)我離開時(shí)我會(huì)檢查的．

解答 答案：D 考查語(yǔ)言交際．Go ahead開始做，著手干；No problem沒(méi)問(wèn)題，好的；No way決不；Don't bother不用麻煩了．依語(yǔ)境可知D項(xiàng)正確．后文"當(dāng)我離開時(shí)我會(huì)檢查的"是解題的關(guān)鍵．

點(diǎn)評(píng) 語(yǔ)言交際是靈活多變的，要注意根據(jù)語(yǔ)言環(huán)境具體問(wèn)題具體分析．要做好這類題，需從以下三個(gè)方面著手：1．仔細(xì)審題，明確大意：首先要仔細(xì)審題，即在對(duì)話不完整的情況下，盡量弄懂該篇對(duì)話的大意和情景（如購(gòu)物、看病、問(wèn)路和應(yīng)答、約會(huì)、口語(yǔ)應(yīng)用等）．2．分析對(duì)話，試填答案：在解題過(guò)程中，要根據(jù)具體語(yǔ)境和上下文，分析對(duì)話中所缺部分、判斷所缺的句子．3．全文復(fù)讀，融會(huì)貫通：在試填好答案之后，應(yīng)從頭至尾再把對(duì)話讀一遍，按照對(duì)話情境，中心內(nèi)容，推理判斷．

6．In 1985，a lionfish was caught off the coast of Florida．Now they can be found not only in the Atlantic Ocean but also in the Gulf of Mexico and the Caribbean Sea．And they are continuing to move south．Lionfish are native to the Indian and western Pacific Oceans．So how did they end up in the Atlantic？Scientists believe some pet owners abandoned their unwanted lionfish and poured them into the sea．Little did they know the trouble their actions would cause．
       The Atlantic Ocean turned out to be a comfortable home for lionfish．Their venomous spines （毒刺） prot ect them from sharks and other fish．Female lionfish can spawn （產(chǎn)卵） every few days，producing as many as 2 million eggs per year．Other big fish would have competed with lionfish for food．But overfishing has removed many of these large fish．As a result，the fish have eaten so much that they have grown to be more than three times the size of their cousins in the Pacific and Indian Oceans．"They eat mostly fish，"says Stephanie Green，a scientist at Oregon State University．
       All that eating has caused great changes．Scientists have found that when lionfish are present somewhere，many other fish，which are small enough for them to eat，disappear．Some of the fish they eat are greatly missed in their habitats．For example，parrotfish eat certain plants off corals （珊瑚），which allows corals to grow better．But they are now disappearing due to lionfish．
       Scientists say lionfish are here to stay．But there are ways to deal with the problem．The key，says Green，is to keep lionfish numbers in check．In Florida，divers can now go through a special training program and get certified （授予合格證書） to catch lionfish in areas where fishing is not usually allowed．And a number of restaurants have added the fish to the menu．"It's going to be a long-term battle，but the missing sea species will come back someday，"says Green．
25．What can we learn about lionfish？D
A．Most of them have gathered in the Atlantic．
B．All of them are almost the same size．
C．They eat other big fish and even sharks．
D．Its population is growing very quickly．
26．Parrotfish were mentioned to show lionfish'sB．
A．loneliness                       
B．harmfulness
C．weakness                        
D．carelessness
27．What is Stephanie Green's attitude towards the battle against lionfish？C
A．She doubts it．
B．She is worried about it．
C．She is hopeful of it．
D．She thinks it is against the law．
