1.主语是rain,可看作是被动关系是通过……方式3。母亲是被照顾,过去分词修饰母亲 et(not)doingsth.ydoing试着做trytodo试一试解释得不大清楚,见谅
A cold rain was falling,___with ice balls。 A mixed B mixing (为什么选A） 被动。选B应该加宾语 My friend Peter lost a lot of weight___every day。
A for exercise B by exercising (为什么选Ｂ） by通过。。。方式 Besides her research work,Mary has a sick mother at home___ A to look after B to be looked after C taken care of (为什么选C） 让人照看 The doctor insisted on__a good rest of before going back to work。
A him to take B his taking (为什么选Ｂ） on之后加ing形式，前面用代词的宾格或者形容词形式 I regretted__your advice。 A having not taken B not having taken (为什么选Ｂ） 动词的非谓语形式否定都加在前面 If you fail,you may try__it in another way。
A to do B doing (为什么选Ｂ） 似乎A更准确一点，换种方式去做。
