Unit4 Wildlife protection单元练习
Ⅰ. 单句语法填空
1．He was worried, because he lost his bag __containing__(contain) his passport，ID card and a lot of money.
解析：句意：他很担心，因为他丢了装有护照、身份证和一大笔钱的包。contain表示“装有”，与bag构成逻辑上的主谓关系，因此应该用containing。
2．His explanation that he is at __a__ loss what to do next doesn't hold water.
解析：考查冠词。句意：他对接下来该做什么感到困惑的解释说不通。at a loss意为“困惑，不知所措”，为固定短语。
3．It was mainly for the environmental protection __that__ the government decided to have a new city built 600 miles northwest of the original one.
解析：考查强调句式。分析句子结构可知，此处为强调句“It is/was＋被强调部分＋that/who”结构，本题强调的是mainly for the environmental protection，因此用that。
4．__Before__ he could call the police, the thieves had run away with the suitcase，leaving him shocked and helpless.
解析：考查连词。句意：他还没来得及打电话报警，小偷已经带着手提箱逃跑了，这使他感到震惊与无助。根据句意可知，before“在……发生以前”正确。
5．I'd appreciate __it__ if you could come and help me once more and I always appreciate __helping__(help) me with my English in the past.
解析：考查appreciate的用法。I'd appreciate it if...为固定结构，意为“假如……，我将不胜感激”；appreciate后可以跟动名词作宾语。
6．With his attention __fixed__(fix) on his mobile phone, he didn't notice his headteacher's appearance.
解析：考查with的复合结构。句意：他只顾看自己的手机，没有注意到班主任老师的出现。“with＋名词/代词＋分词/形容词/副词/介词短语”为with的复合结构，在句子中作状语，表行为方式、伴随、时间等。固定搭配：fix one's attention on sth.集中注意力于……，为固定搭配，本题中attention与fix构成动宾关系，故应用过去分词。
7．Hot __as/though__ the night air was, we slept deeply because we were so tired after the long journey.
解析：句意：虽然晚上很热，但因长途旅行之后很累，我们睡得很沉。as/though“虽然”，引导让步状语从句时，要将表语、状语或动词原形置于句首。
8．There are several ways __that__ we can cross the river without the help of local villagers.
解析：考查定语从句。句意为：在没有当地村民的帮助下，我们有几种过河的方法。分析句子结构可知，这是一个定语从句，that引导定语从句，在从句中作方式状语，修饰先行词ways。注：在定语从句中，当先行词是way时并在从句中作状语，定语从句的引导词可用in which，that或省略关系词。
9．It's standard practice for a company like this one__to_employ__(employ) a security officer.
解析：本题考查非谓语动词。句意：对像这样的一个公司来说，雇用一个安全人员是常规做法。首先分析句子结构和句意可知题干中主系表结构已经很完整了，而且a company与employ之间构成主动关系。只是it所指代的内容还不够明确和详细，所以it是形式主语，真正的主语是后面的不定式短语to employ a security officer。a company like this one 是employ的逻辑主语。
10．Cathy had quit her job when her son was born __so__ that she could stay home and raise her family.
解析：本题考查状语从句的引导词。句意：当儿子出生时凯茜就已辞去了工作，目的是她能够待在家里抚养孩子。so that“目的是，结果是”，引导目的状语从句和结果状语从句。由关键信息，quit her job以及stay home and raise her family可知，stay home and raise her family是前面辞职的目的，故要用so that引导目的状语从句。
11．I'd appreciate __it__ if you could let me know in advance whether or not you will come.
解析：本题考查替代词的辨析。句意：如果你能提前让我知道你是否会来，我将很感激。I'd appreciate it if...意为“如果……我将不胜感激”，这是appreciate的固定句式。
12．They might just have a place __left__(leave) on the writing course—why don't you give it a try?
解析：句意：他们可能只剩下一个写作课的名额了，你为什么不试一试呢？根据句意可知，填left。
13．After school we went to the reading-room to do some reading, only to be told that it was __being_decorated__(decorate)．
解析：本题考查动词的时态和语态。句意：放学后我们去图书馆做一些阅读，结果被告知图书馆正在被装修。“图书馆”与“装修”之间是被动关系；再根据句意可知，图书馆正在被装修，故用过去进行时态的被动语态。
14．—Don't worry, Mum.The doctor said it was only the flu.
—What __a__ relief! I'll tell Dad there's nothing serious.
15．Special attention should be paid to __improving__(improve) your spoken English.
解析：考查非谓语动词。pay attention to中to是介词。

Ⅴ. 教材原句
1．Please take me to a distant land __where__ I can find the animal __which/that__ gave fur to make this sweater.

解析：考查“so＋adj./adv.＋that”句式，意为“如此……以致于……”。

解析：第一空考查词形转换，应用形容词作定语；第二空考查主谓一致，定语从句的谓语单复数形式取决于先行词，该句先行词drug为单数。
4．In Tibet Daisy saw an antelope __looking__ (look) sad.
解析：考查分词作宾补。强调动作正在进行，且antelope与look之间为主动关系，故用looking。

解析：考查动词时态。分析turned around以及found可知watch正在进行且与主语为被动关系。
6．Tourists were allowed __to_hunt__ (hunt) only a certain number of animals if they paid the farmers.
