16．_________，his proposal was turned down during the discussion．（　　）
A．Practical as might it soundB．As it might sound practical
C．Practical as it might soundD．As practical it might sound

分析 雖然該提議聽起來可操作，但是在討論期間被否決了．

解答 答案：C
解析：As引導(dǎo)讓步狀語從句：as引導(dǎo)的讓步狀語從句必須以部分倒裝的形式出現(xiàn)，被倒裝的部分可以是表語、狀語或動詞原形，though也可用于這樣的結(jié)構(gòu)中，但although不可以這樣用．故根據(jù)此用法及所給選項分析可知A、B、D全部都不符合用法，只有C選項符合這一用法及句意．綜上，本題答案為C選項．

點(diǎn)評 本題考查讓步狀語從句，做此類題目時先要確定從句的類型再根據(jù)各個選項的含義及用法并結(jié)合題干選出正確答案．

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．
