1,why dont you +do why not do
2,enough adj.足够的,修饰可数名词或不可数名词,可以放在名词前面,也可以放在名词后面;adv.足够地,修饰形容词、副词、动词,并放在其后.
3,一、 so...that...句型中的so是副词,常常用来修饰形容词或副词,常用句型为：主语+谓语+so+adj./ adv.+ that从句.例如：
二、 在“such...that...”句型中,such修饰名词,意思也是“如此……以致于……”但当名词前有many、much、(a) few、(a) little等词修饰时,句子中要用“so...that...”而不能用“such...that...”.
三、 so与that也可连起来写,即变成：...so that ...(以便 / 为了……),引导目的状语从句.例 1.Please open the window so that we can breathe fresh air.
四、以“so...that”引导的结果状语从句可以转换成不定式的简单句,即可转换为“...enough to...”或“...too...to”句型,但这种转换必须符合下列条件：
1.当主句和从句的主语一致,且that从句是肯定句时,可用“enough to do sth.”来转换.例如：
The man is so strong that he can lift the heavy box.→
The man is strong enough to lift the heavy box.
2.当主句和从句的主语不一致,且that从句是肯定句时,可以用“enough for sb.to do sth.”来替换,但须注意不定式的宾语要省略.例如：
The question is so easy that I can work it out.→
The question is easy enough for me to work out.
3.当主句和从句的主语一致,且that从句是否定句时,可以用“too...to”来替换.例如：
The girl is so young that she can't dress herself.→
The girl is too young to dress herself.
4.当主句和从句的主语不一致,且that从句是否定时,如果要用“too...to...”替换“so...that...”,则用介词for引出动词不定式的逻辑主语,可以用“too...for sb.to do sth.”来替换,注意不定式的宾语要省略.
The bag is so heavy that she can't move it.→
The bag is too heavy for her to move.
4,easy to take care of =easy to look after 容易照顾

7,rather than do

rather than to do

They prefer to die fighting rather than(to) live in enslavement.
他们宁可战死,也不肯活着受奴役.
13)I prefer to work rather than(to) remain idle.我宁愿工作而不愿闲着.
rather than 后接不定式时,不定式可以带to,也可以不带to,如上句.但rather than位于句首时,则只能接不带to 的不定式.如：Rather than allow the vegetables to go bad,he sold them at half price.他唯恐蔬菜烂掉,把它们以半价卖掉了.
接动名词
