2018年高考英語知識點必修三Module 5單元總復習教案
the reason (why...)is that...(……的)原因是……
①the reason why i’m late is that i missed the bus.
我遲到的原因是沒有趕上公共汽車。
②the reason why he was driving so fast was that he would be late for an important meeting.
他把車開得這么快的原因是他參加重要會議要遲到了。
【注意】 reason用作定語從句先行詞時，首先判斷reason在定語從句中作什么成分，如果作狀語，則要使用關系副詞why引導定語從句，而且why有時可省略；如作主語或賓語，則使用關系代詞that/which引導定語從句。
③i didn’t believe the reason (that/which) he gave me.
我不相信他給我的理由。
即境活用
14.the reason ________i was late for the school was ________i was held up by traffic jam in the morning.
a.why；because b.that；that c.that；because d.why；that
解析：選d。the reason后跟定語從句時，用why引導，表語從句用that引導，構成“the reason why...is that...”句型。
15.(高考上海卷)one reason for her preference for city life is ________she can have easy access to places like shops and restaurants.
a.that b.how c.what d.why
解析：選a。句意：她偏愛城市生活的原因之一是在城市里很容易找到像商店和餐館一樣的地方。考查名詞性從句。系動詞is之后是一表語從句，且從句的結構完整，不缺任何成分，所以用that引導。
