② 数词规则:hundred/thousand前有具体数字(one/two/several)时,用原形,不加of;没有具体数字表模糊数量时,加s+of,例:two hundred kinds of plants;hundreds of ants。
重难点3:情态动词表能力与推测
can表现在具备的能力,“能够、可以”,例:Bees can tell each other where food is.;may/might表可能性推测,“也许、可能”,可能性弱于can;must表肯定推测“一定”,can't表否定推测“不可能”。
重难点4:`be famous as` vs `be famous for`
`be famous for`表示“因……(特征/作品/特长)而出名”,后接出名的原因;`be famous as`表示“作为……(身份/物种)而出名”,后接身份、类属。例:The panda is famous as a national treasure of China; it is famous for its cute black and white fur.
重难点5:much修饰比较级
比较级前可用`much/a lot/even/a little`修饰表程度,不能用very/so/too直接修饰比较级,例:The cactus is much stronger than many other plants.
