必修四Unit2同步常考知识点练习

Ⅰ. 单句语法填空

 

1．It's our hope that we will play a greater role in the market place and__therefore__， supply more jobs.

 

解析：考查副词。句意：我们希望我们会在工作市场上起更大的作用，因此提供更多的工作。

 

2．The climate here is quite pleasant, the temperature rarely, if __ever__， reaching 30℃ in summer.

 

解析：本题考查省略句。句意：这里的气候宜人，________，在夏季气温极少达到30摄氏度。if ever如果曾经有；如果曾经发生。根据句中的关键词quite pleasant(宜人)，rarely(极少)可知，空格处表达的意思是“如果曾经有(if ever)”。if ever相当于if it(the temperature) ever reached 30℃ in summer。

 

3．We would rather our daughter __stayed__(stay) at home with us, but it is her choice, and she is not a child any longer.

 

解析：本题考查虚拟语气。句意：我们宁愿我们的女儿和我们一起待在家里，但是那是她的选择，她已经不再是一个小孩子了。would rather后接that从句时，要用虚拟语气，如果与现在或将来事实相反，从句用一般过去时态；如果与过去事实相反，从句用过去完成时。根据后面的it is her choice可以判断这件事情还没发生，因而从句用一般过去时。

 

4．Bears build__up__ fat stores throughout the summer and fall to have energy enough to last them through their winter sleep.

 

解析：句意：狗熊在夏天和秋天开始脂肪的储存以使他们有足够的能量来度过冬眠。

 

5．It sounds like something is wrong with the car's engine.If __so__， we'd better take it to the garage immediately.

 

解析：本题考查省略。句意：听起来好像是车的发动机出毛病了。如果这样的话，我们最好立刻把它带到修车厂去。if so“如果这样的话”。

 

6. The news shocked the public，__leading__(lead) to great concern about students' safety at school.

 

解析：本题考查非谓语动词。根据本句的结构来看，引起的关注正是这条消息令公众震惊的同时所引起的结果，即结果状语，而作结果状语，且表达主动意义。句意：这条消息令社会震惊，引起了人们对在校学生安全的极大关注。

 

7．—Cathy, what are you going to do this weekend?

—__If__possible, I'm going to see my parents in the countryside.

 

解析：答语句意：如果可能的话，我要去看望乡下的父母。if possible如果可能的话。

 

8．At first I regretted __inviting__(invite) them to stay, but we soon became great friends.

 

解析：考查非谓语动词。句意：起初，我后悔邀请他们留下来，但是我们很快成为了朋友。regret doing后悔做了某事。

 

9．I had a busy and tiring weekend because __decorating__(decorate) the house for the Christmas cost me a whole day.

 

解析：考查动名词作主语。句意：我这个周末过的很忙很累，因为装饰圣诞房子花了我一整天。because引导原因状语从句，从句中的cost是谓语，前面是主语，用动名词作主语。

 

10．Wouldn't you rather your child__became__(become) successful with his study and on the scholarship?

 

解析：考查虚拟语气的用法。句意：难道你不想让你的孩子在学业上成功，获得奖学金吗？would rather后面的从句用虚拟语气，即用动词的过去式形式。

 

11．New technologies have made __it__ possible to turn out new products faster and at a lower cost.

 

解析：考查代词。句意：新的技术已经让以更低的成本更快地生产出新的产品成为可能。根据句意可知，it在句中作形式宾语，真正的宾语是后面的不定式。

15．An average of just 18.75cm of rain fell last year, making __it__ the driest year since California became a state in 1850.

 

解析：本题考查代词。句意：去年平均降了18.75厘米的雨，使其成为自1850年加利福尼亚成为州以来最干旱的一年。由语境可知，此处考查的是代词的替代，替代前面提到的last year，为同名同物，同一者，用it。

2．Since then, finding ways to grow more rice__has_been__ (be) his life goal.

 

解析：考查时态以及主谓一致。since引导时间状语时，主句谓语用现在完成时态，且动名词作主语，谓语用单数。

 

3．__Although__he is one of China's most famous scientists, Yuan Longping considers himself a farmer.

 

解析：考查两个句子之间的关系。结合语意可知答案，两句之间表示转折关系。

 

4．__Born__(bear) in 1930, Dr Yuan graduated from Southwest Agricultural College in 1953.

 

解析：考查分词作状语。bear与逻辑主语之间为被动关系，故用Born。

 

5．Spending money on himself or__leading__(lead) a comfortable life also__means__(mean) very little to him.

 

解析：第一空考查“spend money (in) doing sth.”；第二空考查主谓一致，动名词作主语时，谓语动词用单数。

8．Over the past half century，__using__(use) chemical fertilizers__has_become__(become) very common in farming.

 

解析：第一空考查动名词作主语；第二空考查主谓一致和时态，动名词作主语时谓语用单数，根据“over the past half century”可知用现在完成时态。

 

9．They feel that this makes the soil in their fields__richer__(rich) in minerals and so more fertile.

 

解析：考查形容词比较级。根据and后so more fertile可知，此处应填richer。

 

10．Crops such as peas or soybeans put important minerals back into the soil，__making__(make) it ready for crops such as wheat or corn.

 

解析：考查分词作状语。make与前面的句子之间是顺承主动关系，故用现在分词作结果状语，故填making。

 

Ⅳ. 语篇填空

 

①__Although__ he is one of China's most famous scientists, Yuan Longping considers ②__himself__ a farmer, for he works the land to do his research.Indeed, his ③__sunburnt__(sunburn) face and arms and his slim, strong body are just like those of millions of Chinese farmers, for ④__whom__ he has struggled for the past five decades.
