It is going to rain.形容词比较级的构成形式一般分以下几种： 1、单词末尾加“er” 2、以e结尾的单词末尾加“r” 3、双写闭音节词的末尾字母，再加“er” 双写闭音节词也称为重音节词 4、以辅音字母“y”结尾的词，变“y”为“i”，再加“er” 5、在多音节词的前面加“more”，这种后面不用加“er”。 6、不规则的形容词变化，如： 原形，比较级 good/well，better bad,worse many/uch，more little,less far,farther/further 没有比较级的形容词有：right, wrong, woolen等。至于说判断一个形容词究竟是哪类的，这就得靠你将来的累积经验了，一般小学主要学规则的！注：‘/’表示“或者”三者或三者以上相比，表示最高程度时，用“ the十最高级”的结构表示．这种句式一般常有表示比较范围的介词短语．例如： Zhang Hua is the tallest of the three． He works (the) hardest in his class. ②最高级可被序数词以及 much，by far，nearly，almost，by no means，not quite，not really，nothing like等词语所修饰. 例如： This hat is by far／much／nearly／almost／not nearly／by no means/not quite／nothing like the biggest． How much did the second most expensive hat coat? ③表示“最高程度”的形容词，如 excellent，extreme，perfect等，没有最高级，也不能用比较级． ......

Was there an apple on the table last night? 一般过去时口诀 一般过去时并不难，表示过去动作、状态记心间。 动词要用过去式，时间状语句末站。 否定句很简单，didn't 站在动词原形前，其它部分不要变。 一般疑问句也好变，did放在句子前，主语、动词原形、其它部分依次站。 特殊疑问句也简单，疑问词加一般疑问句记心间。 最后一条请注意，动词过去式要牢记。
