语言知识3 ① correct adj. 正确的 ② correct v. 改正 ③ correctly adv. 正确地
课文再现 两种说法都正确,但是第一种听起来没那么礼貌。Both are , but the first one sounds less polite.
迁移运用 He answered the teacher's questions . (correct)

correct; correctly

课文再现处需填形容词作表语，根据释义①“correct adj. 正确的”，填correct；迁移运用处需填副词修饰动词answered，根据释义③“correctly adv. 正确地”，填correctly。

语言知识4 ① That is because+原因 那是因为…… ② That is why+结果 那就是为什么……；那就是……的原因
课文再现 那是因为它是一个很直接的问题。That is it is a very direct question.
迁移运用 He is impolite. That is I refused his request.

because; why

第一空后“it is a very direct question”是原因，对应“① That is because+原因”，填because；第二空后“I refused his request”是结果，对应“② That is why+结果”，填why。

语言知识5 ① include v. 包括；算在里面 ② including prep. 包含在内
课文再现 它们包括像“请你……好吗?”或“我可以问一下……吗?”之类的表达方式。They expressions such as “Could you please...?” or “May I ask...?”
迁移运用 We have to learn nine subjects physics and chemistry. (include)

include; including

第一空，句子缺少谓语动词，“include”为动词，主语“They”是复数，用原形include；第二空，“including”为介词，意为“包含在内”，后接名词作宾语，故填including。

课文再现 有时,我们甚至需要花些时间来导入一个请求。Sometimes we even need to time into a request.
迁移运用 1. I spent one hundred yuan buying the present.
=I spent one hundred yuan the present.
=The present me one hundred yuan.
=I one hundred yuan the present.
2. I spent 30 minutes getting to school.
=It me 30 minutes to school.

课文再现：spend; leading
迁移运用1：on; cost; paid; for
迁移运用2：took; to get

课文再现：根据"sb spend(s) some time doing/on sth"，"花时间导入"用"spend time leading into"，填spend; leading。
迁移运用1：第一空根据"spend...on sth"填on；第二空主语是物，用cost，填cost；第三、四空根据"sb pay(s) money for sth"填paid; for。
迁移运用2：根据"It takes sb some time to do sth"，填took; to get。

I 根据句意或提示完成句子。
1. Knowing how to ask for information in a (politely) way is important.
2. Jack finds it difficult to pronounce some new words (correct).
3. We should say “Excuse me” before (ask) for help.
4. When you request others (do) something, don't forget ______ (request) yourself.

1. polite
2. correctly
3. asking
4. to do；to request

1. 题目要求用适当形式填空，给出词为“politely”，是副词。但此处需要一个形容词来修饰名词“way”，因此应将副词转化为形容词“polite”。
2. 题目要求用适当形式填空，给出词为“correct”，是动词或形容词。但此处需要一个副词来修饰动词“pronounce”，因此应将形容词或动词转化为副词“correctly”。
3. 题目要求用适当形式填空，给出词为“ask”，是动词。由于“before”为介词，后面应跟动名词形式，所以应将“ask”转化为动名词“asking”。
4. 题目中有两个空，第一个空要求填入适当的动词形式来与“request”搭配，构成“request sb to do sth”的结构，所以应填“to do”。第二个空要求填入非谓语动词形式，根据句意“不要忘了请求你自己”，表示动作还未发生，故应填“to request”。
