答案
一、单项选择
1. A。在if引导的条件状语从句中，遵循“主将从现”原则，即主句用一般将来时（will+动词原形），
从句用一般现在时。从句主语it是第三人称单数，否定借助doesn't，动词用原形rain；主句用will
go，所以选A。
2. A。“if”表示“如果”，引导条件状语从句；“when”表示“当……时候”，引导时间状语从句；“before”
表示“在……之前”，引导时间状语从句。这里表达“如果你不早起，你上学将会迟到”，是条件关系，
用if，选A。
3. A。同样遵循“主将从现”原则，if从句用一般现在时，主语是you，动词用原形go，选A。
4. B。“if”从句中，主语he是第三人称单数，动词用第三人称单数形式comes，选B。
5. A。从句用一般现在时，主语是you，be动词用are，选A。

10.A。“should”表示“应该”，这里表达“如果你想交更多的朋友，你应该更外向”，选A。
二、用所给单词的适当形式填空
1. is;willgo。“if”从句用一般现在时，主语it是第三人称单数，be动词用is；主句用一般将来时will+
动词原形，所以填is;willgo。
2. willcall;has。“if”从句用一般现在时，主语 she是第三人称单数，动词 have用第三人称单数形式
has；主句用一般将来时will+动词原形，所以填willcall;has。
3. don'tstudy;won'tpass。“if”从句用一般现在时，主语是you，否定借助don't，动词用原形study；
主句用一般将来时will+动词原形的否定形式won't+动词原形，所以填don'tstudy;won'tpass。
4. willvisit;have。“if”从句用一般现在时，主语 they是复数，动词用原形 have；主句用一般将来时
will+动词原形，所以填willvisit;have。
5. help;willhelp。“if”从句用一般现在时，主语是you，动词用原形help；主句用一般将来时will+动
词原形，所以填help;willhelp。
6. willbe;give。“if”从句用一般现在时，主语是you，动词用原形give；主句用一般将来时will+动词
原形，所以填willbe;give。
7. rains;willstay。“if”从句用一般现在时，主语 it是第三人称单数，动词 rain用第三人称单数形式
rains；主句用一般将来时will+动词原形，所以填rains;willstay。
8. willgo;finish。“if”从句用一般现在时，主语是we，动词用原形finish；主句用一般将来时will+动
词原形，所以填willgo;finish。
9. doesn'tcome;willbe。“if”从句用一般现在时，主语she是第三人称单数，否定借助doesn't，动词
用原形come；主句用一般将来时will+动词原形，所以填doesn'tcome;willbe。
10.willget;work。“if”从句用一般现在时，主语是you，动词用原形work；主句用一般将来时will+动

三、按要求完成句子
1. If;don't;won't。“if”引导的条件状语从句变否定句，从句和主句分别否定。从句主语是you，否定
借助don't；主句用will的否定形式won't，所以填If;don't;won't。
2. Whatwill;do。对“goforapicnic”提问，用what，后接一般将来时的一般疑问句，把will提前，所
以填Whatwill;do。
3. Will;tell;comes。“if”引导的条件状语从句变一般疑问句，把主句的will提前，从句用一般现在时，

goingto。
5. Hurry;or。“Ifyoudon'thurry,you'llbelate.”的同义句可以用“祈使句+or+陈述句”，所以填Hurry;
or。

2. A。根据 “Contact your friends at least once a week by telephone or e-mail, or by visiting them to find
