9、为含有too to / enough to 的简单句。4.

11、 minutes late. the rest 解释为“剩余的（人、物）”，可指代可数名词，相当于the others的用法。也可指代不可数名词，动词用第三人称单数6.

12、要用被动语态。只有及物动词作谓语时才能将主动语态变为被动语态，不及物动词作谓语无被动形态。 结构：v. (P.P.)表示动词的过去分词l 一般现在时被动语态：am / is / are + v.(P.P.)l 一般过去时被动语态：was / were + v.(P.P.)l 一般将来时被动语态：will be + v.(P.P.)l 现在完成时被动语态：have / has + been + v.(P.P.)l 情态动词被动语态： 情态动词 + be + v.(P.P.) 以上五种形式为中考考纲中要求学生掌握的被动语态，还有以下三种为理解要求：l 现在（过去）进行时被动语态：am / is /

13、 are (was / were) + being + v.(P.P.)l 过去完成时被动语态：had been + v.(P.P.)l 过去将来时被动语态：would be + v.(P.P.) 主动语态与被动语态转换的几点建议：1主动语态变被动语态要分清主、谓、宾，把真正的宾语找出后提前作被动句的主语。而主动句中的主语变为by短语，或省略。(如果主动句中的主语是人称代词时，应改为宾格)2在句型转换中，要考虑主谓一致和与原句的时态一致。*3不加to的动词不定式如：make sb. do sth., see sb. do sth.等，变为被动语态时要还原to e.g. The manager

14、makes the girls work in the shop all day long. (改为被动态) The girls are made to work in the shop all day long.*4含双宾语动词词组，如：give / pass / teach sb. sth. = give / pass / teach sth. to sb. buy / makesb. sth. = buy / makesth. for sb. 变被动态语态时，直接宾语和间接宾语都可与提前为被动语态的主语e.g. 1. Dad gave me some toys as my birthday presents. (改为被动态) I was given toys as my birthday presents. Some toys were given to me a
