一、将来完成进行时
1.概念:表示动作从某一时间开始一直延续到将来某一时间。是否继续下去,要视上下文而定。
2.基本结构:shall/will have been doing
3.例子:I shall have been working here in this factory for twenty years by the end of the year.到今年年底,我将在这个工厂工作20年了。
If we don't hurry up the store will have been closing before we get there. 咱们如不快一点儿,等我们到了那儿,店门就会关了。
二、 过去将来完成进行时
1.概念:表示从过去某时看至未来某时以前会一直在进行的动作。
2.基本结构:should/would + have + been +现在分词
3.例子:He told me that by the end of the year he would have been living there for thirty years.他告诉我,到年底时,他就在那住了30年了。
使用被动语态应注意的几个问题:
1. 不及物动词无被动语态。
What will happen in 100 years.
The dinosaurs disappeared about 65 million years ago.
2. 有些动词用主动形式表示被动意义。
This pen writes well.
This new book sells well.
3. 感官动词或使役动词使用省略to的动词不定式,主动语态中不带to ,但变为被动语态时,须加上to 。 例:make somebody do something→somebody+ be +made to do something
ee somebody do something→somebody +be +seen to do something
A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by. The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
4. 如果是接双宾语的动词改为被动语态时,直接宾语(物)作主语,那么动词后要用介词,这个介词是由与其搭配的动词决定。
He gave me a book.→A book was given to me by him.
He showed me a ticket.→A ticket was shown to me by him.
My father bought me a new bike. →A new bike was bought for me by my father.

所谓垂悬结构(The Dangling Construction)就是一个句子成分,如分词短语,不定式动词短语等,找不到被修饰的主语或被修饰的对象不合逻辑。垂悬结构是种错误的句法,应该避免。
下面是三种常见的垂悬结构及其改正方法:
⒈垂悬分词或分词短语,如:
①Climbing up the hill, several boars were seen.
这句子里的现在分词短语(present participial phrase)修饰主语“several boars”是错的;改正方法有二:
(a)确定是逻辑主语,使句子变成“Climbing up the hill, the explorers saw several boars.”
(b)把现在分词短语扩大为副词分句(也称状语从句):“When the explorers climbed up the hill, they saw several boars/ several boars were seen.”
⒉垂悬副词短语,如:
After putting a shrimp on the hook, the fish began to bite.
这句的副词短语(adverb phrase)和主语“the fish”有什么逻辑关系呢?真正的逻辑主语应该是“the fisherman”或“the angler”才对。改正方法:
(a) After putting a shrimp on the hook, the fisherman found that the fish began to bite.
(b) After the fisherman had put a shrimp on the hook, the fish began to bite.
⒊垂悬不定式动词短语,如:
To write well, a lot of practice is needed.
To be a loyal employee, a sense of belonging is a must.
这两个句子的不定式动词短语(infinitive phrases)并不能修饰“practice”和“a sense of belonging”,真正的主语必须是“ 人”,如:
(a) To write well, one needs a lot of practice/a person has to practise a lot.
(b) To be a loyal employee, he or she must have a sense of belonging.
上述三类垂悬结构中,第一类发生的频率,必须注意。但是在下列三种情况下,分词短语是对的,它们并非垂悬结构:
第一,独立结构(The Absolute Construction,见3月7日《中英合谈》)中的分词短语有自己的主语,所以不是垂悬结构。例如:
uch being the case, we can go home now./……it is not wrong to call it a day.
第二,当分词含有介词或连词性质时,它不需要逻辑主语,所以没有垂悬问题存在。例如:
Owing to a lack of funds, the project has to be discontinued.
rovided that there is sufficient time, everyone can do the job better.
第三,当分词短语是用来表示说话者的态度或意见时,也不需要逻辑主语,因此也不存在着垂悬问题。例如:
Judging from his facial look, the news must have been terrible.
Taken as a whole, there is nothing wrong with the logic behind that idea.

一、名词的数
1.单数和复数
可数名词有单数和复数两种形式。复数形式通常是在单数形式后加词尾“-s”构成,其主要变法如下:
(1)一般情况在词尾加-s,例如:book→books,girl→girls,boy→boys,pen→pens,doctor→doctors, boy→boys。
(2) 以s,x,ch,sh,结尾的词加-es,例如:bus→buses,class→classes,box→boxes,watch→watches,brush→brushes。
(3)以ce, se, ze,(d)ge结尾的名词加s,例如:orange-oranges。
(4) 以辅音母加y结尾的词变“y”为“i”再加-es,例如:city→cities, factory→factories, country→countries, family→families。但要注意的是以元音字母加y结尾的名词的复数形式只加s,如:boy→boys, day→days2016九年级英语上册重要知识点总结2016九年级英语上册重要知识点总结。
(5)以 o结尾的词多数都加-es。例如:hero→heroes,potato→potatoes,tomato→tomatoes,但词末为两个元音 字母的词只加-s。例如:zoo→zoos,radio→radios,还有某些外来词也只加-s,例 如:photo→photos,piano→pianos。
(6) 以f或fe结尾的词,多数变f为v再加-es,例如:knife→knives,leaf→leaves, half→halves。
复数词尾s(或es)的读音方法如下表所示。

(7)少数名词有不规则的复数形式,例如:man→men,woman→women,tooth→teeth,foot→feet,child→children,mouse→mice。
【注意】与man和woman构成的合成词,其复数形式也是-men和-women。例如:an Englishman,two Englishmen。但German不是合成词,故复数形式为 Germans;man, woman等作定语时,它的单复数以其所修饰的名词的单复数而定,如:menworkers, women teachers。
有个别名词单复数一样,例如:Chinese,Japanese,sheep,deer,fish等但当fish表示不同种类的鱼时,可以加复数词尾
(8)单数形式但其意为复数的名词有:people, police等。
(9)数词+名词作定语时,这个名词一般保留单数形式,中间加连字符。例如:ten-minutes’ walk, an 8-year-old girl, a ten-mile walk。
(10)还有些名词仅有复数形式,如:trousers,clothes,chopsticks,glasses,goods,ashes,scissors,compasses。

1.依据上下文确定答案的法则:从近几年的完形填空题看,近义词或近义短语的测试力度逐渐加强,并成为测试热点。四个选项不是词义相近,要不就是近义动词的同一种时态的现象,或名词的单复数搭配。若选项词义差异很大,必然文章中藏有提示语,正因如此,往往第一个选项有时需要读完全篇短文才能准确回答。
2.词语语义与强于语法原则:完型填空题的首句不留空,目的就是告知短文的故事的四要素:地点、时间、人物和事由。再则,单纯语法题已基本退出该题型的测试范畴,所以,指导学生时,首先要告知他们这类现象。尽管四个选项的词语都符合语法规则,然而该题的解答必须遵循先全面理解篇章语义,再结合正确语言结构对每个空格作出准确无误的抉择。
3.解题四步法原则:
第一步:跳读。带着空格通读全文,了解短文大意,判别短文文体,同时能将会做的题及时解决掉。
第二步:选答。这一步最为关键,要求考生对每一道题进行认真推敲,但是要告诫他们万万不可按照题的顺序答题,对那些不能拿不准的题先跳过去,遵循先易后难的解题原则。
第三步:推敲。这实际上就是要求考生对完形填空短文的篇章作通盘考虑,把其中一些需要依据上下文语境来考虑的比较难解答的题,以及句子之间和段落之间的逻辑关联较强的认真推敲,甄别,筛选和抉择。
第四步:复查。这是解答这类题的最后一步,要求考生解完题之后务必再把文章通读一遍,从整体上准确把握文章的真正意思,及时修改与全文有出入的一些选项。
