discuss:
1.分词短语discussed yesterday作定语=which was discussed yesterday.
2.进行时态的现在分词短语being discussing now作定语,意为“现在正在(被)讨论的”.
3.不定式短语to be discussed tomorrow作定语可用于表将来.
arrive:
现在分词独立结构Arriving at the farm作状语,后面的主语we执行arrive这个动作.
选B 理由:在全体中排除部分,用except for; 排除全部,用except.表示“除了…(还有…)”用besides,而beside是介词,意为“在…旁边”
(B)——选A(saying).理由:这是分词独立结构,所以用现在分词,是因为前面的主语要执行say这个动作(如果主语是要承受这个动作,就要用过去分词)
选D (weighing).理由:动词weigh的用法如Tom weighs 69 pounds.原句中要表达“小孩重多少”这一概念,小孩执行weigh这个动作,所以用现在分词.
改错：
The (surprise) on his face showed that he hadn'g expected it.这里surprising要改成其名词形式surprise.
(Given one more hour),I will get the work finished.理由:从句子被逗号分为两部分可以估计前面部分可能是独立结构,由于I要承受give这个动作,所以用过去分词.
(B)As a new grduate ,he doesn't konw——(what )it takes to start a business here.理由:变换次序成it takes ( ) to start …,就清楚这里要填what了.
(B)Michael put up a picture of Yao Ming beside the bed to keep himself (reminding) of his own dreams.英语keep sb doing sth使某人持续做某事.
The difference in thickness and weight from the earlier verion makes the ipad2 more comfortable (to hold)
 (D)(C Being exposed) to the sunlight too long will do harm to your skin.理由:容易看出句子主语为will之前的部分,注意到这不是复合句(will前没有其它主语,故不可能用独立的过去分词,而要用具有名词作用的动名词,于是只剩下C D了.由于这里在陈述事实而未涉及动作的时间先后及因果关系,故不能用完成式,因此选C ).
再问： 亲，最后第二个没给解答啊，求~~~~ 还有那个surprising 答案上是该为surprised 求解~~~
再答： 那个surprising 他的答案肯定错了，因为若用surprised 由于其前面有定冠词，其后就必须有其它名词！ 回到倒数第二个。这里你可能会问怎么不用to be held，这是许多人存在的问题。其实，类似的句子有好多。比如“这包太重，拎不动”，如果用too …to …结构，The box is too heavy to ( )，(这里你可能认为包是“被”拎的，所以用be taken ,但)实际上要用to take.
再答： 对于这类问题，你或许可以把句子变换一下:把the box 放到(to) take后面去，然后是is too heavy ，如果变换后句子顺畅，就说明选择主动语态的to take是正确的。
再问： 实在太谢谢啦 大神╭(╯ε╰)╮
