Ⅱ.完成句子

1.The goods will be well packed after ________________(认真检查),and sent to the named port for sailing.(inspect)

解析:考查句子的省略。inspect的主语应为goods,当主、从句主语前后一致时,可以采用“连词+分词”的省略形式;由于主语与动词是被动关系,故用过去分词。

答案:carefully inspected

2.As we drew closer,I could see a whale ________________(遭受攻击)by a pack of about six other killers.(attack)

解析:考查补语结构。本句运用了“see +宾语+ doing”的结构形态;由语境提示可知“遭受攻击”应是被动进行时,故用“see +宾语+ being done”结构。

答案:being attacked

3.No one has come up with a convincing explanation of ________________(恐龙为什么灭绝了).(die)

解析:考查宾语从句。本题是why引导的宾语从句,“灭绝”应表达为die out。

答案:why dinosaurs died out

4.Mr.Johnson insisted that the problem worthy of attention ________________(讨论) at the meeting.(discuss)

解析:考查虚拟语气。 insist引导的宾语从句要用虚拟语气,即“(should)+ 动词原形”;主语 problem与“讨论”之间是被动关系,因此答案为(should) be discussed。

答案:(should) be discussed

5.As ________________(空气正在受到污染),many kinds of wild animals are dying out.(pollute)

解析:考查动词的时态、语态。

答案:the air is being polluted

6.________________(正如报告里所说),the new machine will work twice as fast,thus reducing costs.(put)

解析:考查定语从句。放在句首作主语的关系代词应用as,由于是被动关系,故答案为As is put in the report。

答案:As is put in the report

7.Had I known about this computer program,a huge amount of time and energy ________________(省下了).(save)

解析:考查虚拟语气。从句是省略if的条件句,而且是完成时态,因此对应的主句也应是完成时。

答案:would have been saved

8.It is for the first time in my life ________________(我认识到了) the importance the government has attached to the environmental protection.(appreciate)

解析:考查强调句型。由句式结构可知本题是一个强调句型,由for the first time in my life可知“认识到了”应用现在完成时,因此答案为that I have appreciated。

答案:that I have appreciated

9.At present,lots of food,water,tents,and medicine ________________(正在运往)from all over China and other parts of the world to the earthquake-stricken areas.(transport)

解析:考查主谓一致和被动语态。本题主语是lots of food,water,tents,and medicine,因此谓语用复数形式;由提示语可知是被动进行时。

答案:are being transported

10.So difficult ________________(我感到)it to live in an English-speaking country that I determined to learn English well.(feel)

解析:考查倒装结构和时态。“So+ adj./adv.”置于句首时,主句谓语要用部分倒装形式;由语境可知“感到”的动作应指过去,因此要提取助动词did来倒装。

答案:did I feel

Ⅲ.完形填空

Words:307 难度系数:☆☆ 建议用时:12′

【解题导语】 在这个世界上有很多国家、很多人非常关心“战争、金钱和权力”这些所谓重要的东西,但很少有人会关注“全球变暖”这个问题,或认为个人对“全球变暖”无能为力。对此我们难道真的束手无策吗?文章将会告诉我们答案。

1.A.When         B.As
