20．Take action and do       you can or it won't be long before people who trust you look for other choices．（　�。�
A．whereverB．whicheverC．wheneverD．whatever

分析 采取行動做任何你所能做的；否則不久信任你的人們會尋找其它的選擇．

解答 答案為D．本題考查賓語從句中引導(dǎo)詞的運(yùn)用．動詞do后面的賓語從句中省略了do，而接物動詞do后面缺少賓語，A和C都是副詞不做賓語，排除；whichever表示"選擇"，本題中無選擇的含義，排除；whatever在名詞性從句中可做主語、賓語、表語或定語，故答案是D．

點(diǎn)評 名詞性從句考查的關(guān)鍵是連接詞的選用和語序，因此，我們首先要搞清從句的性質(zhì)，掌握各連接詞的用法，在此基礎(chǔ)上判斷．此外，關(guān)注名詞性從句用陳述語序．

18．It may seem like a moment in a science fiction movie．In a fierce battle，a creature loses an arm but，then，grows another one to take its place．
However，this is not science fiction．It is scientific fact．Some fish and amphibians，such as salamanders，can regrow lost limbs and organs．
As mammals evolved they lost the ability to regrow，or regenerate，parts of their body．However，experiments show that it may be possible to regain that ability．
Tropical freshwater zebrafish are popular pets．They are also popular as lab animals．Their embryos（胚胎） are clear，or translucent．They can regrow damaged fins，skin and hearts．Zebrafish are also genetically（基因地） similar to humans．
In 2013，the website Sci-News reported that researchers had found that 70per cent of"protein-coding human genes"are related to genes found in the zebrafish．The report also said that researchers at the Wellcome Trust Sanger Institute in Britain also found that 84per cent of genes known to be connected to human disease have a zebrafish counterpart．
Scientist Wang Yadong is one of the Pittsburg researchers．He and his team are studying the ability of zebrafish to regenerate limbs and organs．Wang says you can cut away about 20per cent of the zebrafish heart and it will regenerate．He add that same process may be able to help humans．
Scientists injected（注射） an"extracellular matrix，"or ECM，from the heart of a zebrafish into a severely damaged mouse heart．They found that the heart muscle regrew in days．They found something else．The healing was even faster when the ECM was taken from zebrafish that was itself in the process of re-growing damaged tissue．

12．The main reason why the zebrafish were chosen as lab animals is thatC．
A．they are popular pets
B．their bodies are clear to study
C．they are genetically similar to humans
D．they are easy to find for the researchers
13．What does the underlined word"counterpart"in Paragraph 5probably mean？A
A．A similar thing．
B．A different fish．
C．A human being．
D．A little mouse．
14．After injecting ECM from a zebrafish into the damaged mouse heart，what did scientists find？B
A．The zebrafish died quickly．
B．The mouse heart regrew in days．
C．The zebrafish heart regrew quickly．
D．The mouse healed more slowly than normal．
15．Where is the most probably taken from？D
A．A science fiction．
B．A guide book．
C．A fashion magazine．
D．A science report．
