Unit 3 Inventors and inventions grammar课时作业

Ⅰ.单句语法填空

　　1．Choosing an ________ (occupy) takes time, and there are a lot of things you have to think about.

　　答案：occupation　occupy为动词"占用；占领；占据"；occupation名词"占领；职业；工作"。由设空前的冠词an可知此处应填名词。

　　2．Were it not for science, we could not live a ________ (comfort) life.

　　答案：comfortable　此处需用形容词修饰名词life。live a comfortable life "过一种舒适的生活"。

　　3．It is ________ (acknowledge) that China has become one of the strongest countries in the world.

　　答案：acknowledged　It is acknowledged that ... "人们认为/据认为......"。

　　4．I recommend him ________ (think) very carefully before he does anything foolish.

　　答案：to think　recommend sb. to do ... "建议某人做某事"。

　　5．It is required that the new employees ________ (provide) safety training before they start to work.

　　答案：(should) be provided　It is required that ... (should) do ... "据要求......"为固定句式；此处从句主语employees与所给动词之间为被动关系，故用被动语态。

　　6．To finish the job in an hour is out of ________ question.

　　答案：the　out of the question "不可能的"。

　　7．As far as I'm ________ (concern), it's time to share some secrets with you.

　　答案：concerned　as far as I'm concerned "在我看来；就我而言"。

　　8．He got the first prize in the competition, ________ was a surprise to his parents.

　　答案：which　该句为which引导的非限制性定语从句，指代主句提到的整件事，在从句中作主语。

　　9．Who do you ________ (think) is fit for the job?

　　答案：think　do you think在句中作插入语，构成"特殊疑问词＋do you think＋陈述语序"结构。

　　10．She wondered ________ to win the game.

　　答案：how　"特殊疑问词＋to do"在该句中充当宾语，此外还可以充当主语、表语等。

　　Ⅱ.单句改错

　　1．Rose is really comfort to all of us. She brings us a lot of fun and happiness.

　　______________________________________________________

　　答案：comfort前加a　comfort表示"舒适；舒服；安慰"讲时为不可数名词，作"令人安慰的人或事"讲时为可数名词，即此处为"抽象名词具体化"的用法。

　　2．Occupying with various research projects all day, he was tired out.

　　______________________________________________________

答案：Occupying→Occupied　(be) occupied with ... "忙着做......；忙于某事物"，形容词短
