unless的用法
unless意为＂除非，如果不＂，引导条件状语从句。unless引导的条件状语从句，若主句、从句的动作均未发生，则主句用一般将来时、祈使句或含有情态动词的句子，从句用一般现在时代替一般将来时。
I shall g unless it rains. 如果不下雨我就去。
I wn’t let yu in unless yu shw me yur pass. 如果你不出示通行证，我就不让你进来。
We’ll g t twn unless it rains tmrrw. 假如明天不下雨，我们就去城里。
注意：
（1）unless通常可以与if... nt结构进行相互转换。
Yu will fail unless yu study hard.
=Yu will fail if yu dn’t study hard.
除非你努力学习，否则你会失败。
（2）若unless引导的从句本身为否定句，则unless不能用来替换。



（2016﹒江苏泰州）—The nvel seems a little bring.
—Yu wn’t enjy it _______________ yu put yur heart int it.
A. whenB. if
C. afterD. unless
【答案】D
【解析】考查连词的用法。句意：——这部小说似乎有点儿无聊。——如果你不用心读的话，你不会享受到这本书。when，当……的时候；if如果；after在……之后；unless，如果不，除非。结合句意，故选D。
as sn as的用法
as sn as一……就……，强调两个动作几乎是连在一起的，后接从句。当主句是一般将来时，as sn as引导的状语从句应用一般现在时代替将来时。指紧接着发生的两个短动作，主句用一般过去时，从句也用一般过去时。有时，为了特意表达刚刚完成某事就如何如何，需要用现在完成时。
The students became quiet as sn as the teacher came in. 老师一进来，学生们就安静下来了。
I will tell him the news as sn as he cmes back. 他一回来，我就告诉他这个消息。
I’ll return the bk as sn as I have finished reading it. 我一读完就把书还回去。
He will cme and see yu as sn as he can. 他一有空就来看你。
The stars came ut as sn as it was dark. 天一黑，星星就出来了。
注意：
as sn as 引导的时间状语从句在过去时态中主从句时态保持一致；若主句用一般将来时态，则从句用一般现在时态。

【名师点睛】本文是一篇人物故事类短文阅读。考查的题型是完形填空。做完形填空首先要通读全文，了解文章的大意，大致了解文章的体裁，主旨大意，背景和内容，同时也要对空格的部分进行初次猜测。然后联系上下文，去认真推敲每一个空。有的答案在下文有暗示，如第1小题，根据下文中的句子He ften used sticks t draw pictures n the grund.可知，马良十分喜欢画画，答案为C。如果是形容词，还要注意它们的用法区别，如第8小题，结合语境可知，马良得到了梦寐以求的画笔，自然非常兴奋，排除A、B，以后缀-ed结尾的形容词(excited, bred, interested, , surprised等) 通常用于说明人，以后缀 -ing 结尾的形容词(exciting, bring, interesting, surprising等)主要用于说明事物，故答案为D。

【文章大意】九岁女孩Mac Macphersn很期待迪士尼世界之旅。妈妈答应她如果她能为慈善机构筹集500美元，她的愿望就可以实现。后来，小女孩在父母的帮助下，通过给别人画肖像，在短短的一天时间就筹到大约550美元。她决定把钱存起来，用以帮助那些来自不同国家需要帮助的孩子。这也是妈妈对孩子的爱心教育。
1. lking 【解析】句意：九岁女孩Mac Macphersn很期待迪士尼世界之旅。lk frward t期望，盼望。此句是过去进行时态，缺少过去分词，结合句意可知，答案为lking。
4. Hwever 【解析】句意：然而，令她惊讶的是，Mac在短短的一天时间就做到了！根据前后语境判断，此处表示转折关系，故答案为Hwever。
【点睛】hwever 与but区别：hwever与but 两者都做＂但是，然而＂讲，而且都引出并列句。从语意上看，but所表示的是非常明显的对比，转折的意味比hwever要强；从语序上看，but总是位于所引出的分句之首，而hwever却可位于句首、句中和句末；同时从标点符号上看，but之后一般不得使用逗号，而hwever则必须用逗号与句子其他部分分开。
5. by 【解析】句意：Mac是通过绘制肖像画来筹集这笔资金的。by ding sth.通过做某事，by表示方法手段，故答案为by。
6. fr 【解析】句意：我学画画已经很长时间了。fr + 一段时间，结合句意，答案为fr。
7. With 【解析】句意：在她父母的帮助下，一个星期六的早晨，Mac在东部市场搭起了一个帐篷和一个画架。with ne’s help在某人的帮助下，由句意可知，答案为With。
8. vice 【解析】句意：她站起来，大声说：＂你想要一个肖像吗？＂此处缺少名词的单数形式，结合句意可知，答案为vice。
9. raised 【解析】句意：她筹集了大约550美元。前文出现句子＂Her mther prmised her the trip if she culd raise $500 fr charity (慈善机构).＂最终，小女孩筹到550美元。前后句子都为一般过去时态，陈述过去发生的一件事，故答案为raised。
10. help 【解析】句意：我喜欢画画，知道我可以帮助其他孩子，这让我感觉很棒。为慈善机构筹集善款的目的就是帮助那些需要帮助的人，故答案为help。因为情态动词can后跟动词原形。
