3.词义揣测题.依据文章其次段的Itmeansthetigers'orangecolourationlooksgreentothem,allowingthemtomixperfectlyintothebackground,newresearchclaims.可知探讨表明,这意味着老虎的橙色对于鹿来说看起来很绿,可以让它们完备融入背景.说明老虎是通过伪装来捕杀猎物的,故选C.

4.推理推断题.依据最终一段"哺乳动物无法长出绿色皮毛""世上已知的哺乳动物中只有一种有绿色皮毛但却是通过被认为可能是欺诈的手段才实现的,不是真正的绿色"可推断,世界上没有绿色皮毛的哺乳动物.故选C.5答案及解析：答案：G;E;B;A;D解析：6答案及解析：答案：1.D;2.A;3.C;4.B;5.A;6.D;7.B;8.C;9.D;10.B;11.A;12.C;13.D;14.B;15.A;16.C;17.B;18.D;19.A;20.C

解析：1.D〔提示:考查动词辨析.作者开车到镇卜.希望(hoping)找到那间旧理发店。〕

2.A提示:考查动词辨析。当作者四处游荡(wandered)时,看到那些旧建筑被替换成新的高层建筑,作者有点悲观。

3.C〔提示:考查动词辨析。那些旧建筑被新的高层建筑所代替(replace)。hereplacedwith是固定搭配,意为“被替换为...”。〕

5.A〔提示:考查名词辨析。依据下文“theyoungmanhadnolegs”可知,这个年轻人没有腿,所以他应当是坐着轮椅(wheelchair)。〕

6.D〔提示:考査名词辨析。依据下文可知,这个年轻人说:“我要一双新鞋。”,所以他是一名顾客(customer)。〕

7.B〔提示:考查形容词辨析。作者发觉说要一双新鞋的年轻人尽然没有腿,所以他感觉特别惊讶(shocked)。〕

8.C〔提示:考查形容词辨析。依据前文可知,作者和店员都惊讶于这个没有腿的年轻人尽然来买鞋,所以年轻人看到了他们感到很怀疑(puzzled)。〕

9.D〔提示:考査名词辨析。当我还是-个孩子(kid)时,我父母每年都给我买一双新鞋。〕

10.B提示:考查代词辨析。那真是一种奇妙的感觉我从来没有遗忘过。这里是说父母给他买鞋的回忆是特别重要的事(something)。他从来不会遗忘。

1.toadjust

2.of

3.horribly

4.lost

5.heard

6.what

7.best

8.the

9.Looking

10.thanks

解析：1.toadjust考查不定式短语作真正主语。Itis/wasveryhardforsb.todosth.意为“对某人来说做某事很难”。2.of考查固定搭配。lackofsth.意为“缺乏某物”。3.horribly考查副词作状语。4.lost考查过去分词作宾补。lost此处意为“迷失的”,可视为形容词,表示一种心境、状态,不表被动。5.heard考查动词的时态。依据“Iwasn'tinterestedwhenI________”可知,此处应用一般过去时。6.what考查宾语从句。宾语从句中缺少宾语,且指物,故填what。7.best考查固定短语。domybest意为“尽我最大努力”。8.the考查冠词。名词后有定语修饰,故应特指。9.Looking考查非谓语动词。look与主语I为主动关系,故用现在分词作状语。10.thanks考查名词。thanksandgratitude为常用短语,该名词短语作have的宾语。8答案及解析：答案：
