【分析】
本题主要考查if引导的条件状语从句的用法(含“主将从现”规则)、祈使句的结构及if作为连词的词义辨析。解题思路:先判断每个小题中if的用法类型,若为真实条件状语从句,遵循“主句用一般将来时,从句用一般现在时”的规则;若为祈使句(表建议、命令等),则用动词原形开头;单项选择需结合句意和语法规则确定连词或动词形式。
【解析】
(1) ① 此句为if引导的真实条件状语从句,从句需用一般现在时,主语it是第三人称单数,故rain变为rains;
② 从句主语是you,否定形式需借助助动词don't,故填don't;
③ 此句为if引导的真实条件状语从句,主句需用一般将来时,故填will pass;
④ 从句主语this是第三人称单数,一般现在时中动词用第三人称单数形式,故go变为goes;
⑤ 此句为祈使句(表建议),需用动词原形开头,故填Keep;
(2) ① 此处为if引导的真实条件状语从句,从句主语my grandma是第三人称单数,be动词用is,故选A;
② 句意为“如果父母不在身边,我们就不能去游泳”,需用表“如果”的连词if,故选C;
③ 此处为祈使句(表建议),需用动词原形开头,故选D。
【答案】
(1)①rains ②don't ③will pass ④goes ⑤Keep;(2)①A ②C ③D
【知识点】
if条件状语从句、祈使句、一般现在时
【点评】
本题为初中英语基础语法题,聚焦if引导的条件状语从句核心规则(主将从现)及祈使句结构,是英语语法的重点考点,需学生熟练掌握相关规则并灵活运用,难度适中。

【分析】
本题为用所给单词适当形式填空,需结合词性规则、固定搭配、名词单复数等知识点解题:
1. 定冠词the后需接名词,detail是可数名词,此处表泛指多个解题细节,需用复数形式;
2. 修饰名词session需用动名词作定语,构成固定搭配training session(训练课程);
3. 固定搭配have difficulty (in) doing sth.中需用名词形式,需将形容词difficult转换为名词;
4. line是可数名词,some后接可数名词复数,需用复数形式;
5. 固定搭配take...seriously中需用副词修饰动词take,需将形容词serious转换为副词。
【解析】
1. 定冠词the后接名词,detail为可数名词,此处表多个细节,故填details;
2. 动名词training作定语修饰名词session,构成固定短语training session,故填training;
3. 固定搭配have difficulty (in) doing sth.表示“做某事有困难”,需用名词形式,故填difficulty;
4. line是可数名词,some后接可数名词复数,故填lines;
5. 副词seriously修饰动词take,构成固定搭配take...seriously(认真对待),故填seriously。
【答案】
