【名师点睛】
在虚拟语气中，be动词只能用were；虚拟条件句省去连词if时，从句主谓部分倒装：Were/Had/Should+主
语+谓语动词...
e.g. Were I Tom, I would refuse. 如果我是汤姆，我会拒绝。
I will go, should it be necessary. 假若有必要，我会去的。
Had it not been for the bad weather we would have arrived in time. 若不是天气坏，我们就准时到达了。
若条件从句为否定句，否定词not应置于主语之后，而不能与were, should, had 等缩略成Weren’t, Shouldn’t,
Hadn’t置于句首。
2．that句意：当我回到我的公寓的时候，我首先遇见了我的新邻居。根据关键词It was开头，后面连词首选that，，构成强调句型，但需要验证，本句中去掉It was 和that，句意完整，所以确定是强调句型。【名师点睛】判断一句话是否是强调句的一个方法是去掉强调结构，如果这句话还能够成立就是强调句，例如这道题，去掉强调结构是：when I got back to my apartment ______ I first came across my new neighbors..这句话是成立的，所以是强调句。除了强调句的陈述句，还需要掌握强调句的一般疑问句和特殊疑问词的结构，还有强调句做名词性从句的语序问题。
3．came [句意：接着年终颁奖典礼来了。时间副词then放在句首，句子要全部倒装。]
4．disabled [句意：在这里我学习到了重要的一课：尽管我在语言上有困难，我仍然能够用泥土完好灵活地表达我自己。设空处为as引导的让步状语从句，此处表语提前至句首，相当于Although I was disabled in language...。]
5．nor [句意：很可能婴儿一出生就不知道天地万物的基本事实，他们也不会被清楚地教授。此处为“nor ＋助动词/系动词/情态动词＋主语”倒装结构。]
6．did [考查部分倒装。句意：直到最近他们才鼓励农村地区发展旅游相关的活动。根据句首的Not until recently可知，本句要用倒装形式。]
7．would 8.did 9.are
10．that [句意：你在一个错误的地方等待。大客车是在旅店接送游客的。考查强调句，其结构是：It is/was ＋被强调部分＋that＋其余成分，如果被强调部分是人，也可以用who，这句话强调的是地点状语at the hotel。]
11．that [考查强调句。该句为it is not until...that...强调结构，句中第二个that引导的是定语从句，先行词为projects，从句动词create 缺少宾语，that代指projects。]
12．did 13.has 14.dealing
15．Sounds [句意：——电影在八点半开始，我们走之前可以迅速吃点东西。——听起来很棒。此处为省略句， That sounds great.为其完整形式。]

2020届高考一轮复习语法专项十七：连词连词分为并列连词和从属连词两大类。并列连词是连接主语与主语，谓语与谓语，句子与句子，分词与分词的词，它要求前后两部分有相同的形式和语法作用；而从属连词一般连接主句与从句，从句形式有名词性从句，定语从句和状语从句等。 （一）并列连词： 并列连词可用来连接词与词，词组与词组，分句与分句。常用的并列连词有：and（和），as well as（既…又），both … and（不但…而且），not only … but also（不但…而且），not … but（不是…而是），neither … nor（既不…也不），either … or（不是…就是），or（或者），but （但是），yet（然而），for（因为），so（所以），while（而），when（这时）等。如：Both my brother and my sister are teachers./ His room is bright but mine is gloomy（暗沉沉的）./ He can not only repair radios but also fix them./ It is a glorious（光荣的）yet difficult task./ Strike while iron is hot. （二）从属连词 从属连词是指在复合句中引导从句的连结词。常见的从属连词有： 引导时间状语从句的：after, before, when, as, while, since, until, till, as soon as 引导原因状语从句的：because, since, as 引导让步状语从句的：although, though, no matter（无论）, even if (though) 引导条件状语从句的：if, unless, once, so (as) long as 引导结果状语从句的：so … that …, such … that … 引导目的状语从句的：so that …, in order that … 引导比较状语从句的：as … as …, not so (as) … as …, … than … 引导方式状语从句的：as if … 引导主语，宾语或表语从句的连词主要有：that, whether, if三个。其中that 和whether 间或还可以引起同位从句和状语从句。 （三）某些用法比较特殊的从属连词用法区别 1、当while, when, as引导时间状语从句时的区别：①while引导的状语从句中动词必须是持续性。谓语动词多为进行时，或状态动词的一般时。while 的这些用法可用when代替，等于“at the time that”, “during the time that”。例如：Please keep quiet while (when) others are studying；② when除可指一段时间外，还可用来指一点时间，等于“at the time”，也就是说
高考英语语法复习专题（2）名词性从句(附参考答案) 1、名词性从句中连接词的运用 名词性从句中的连接词有连词that / whether / as if，连接代词what / who/ which / whose / whatever / whoever / whomever / whichever，连接副词where / when / why / how / wherever / whenever。 （1）that的用法。 ①主语从句、表语从句、同位语从句中用that但不能省略。如： That they are good at English is known to us all. The problem is that we don’t have enough money. She expressed the hope that they would come to China one day. ②宾语从句中的连接词that有时可省有时又不可省，在以下几种情况中that不能省略：（A）当that 从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时，that不可省略；（B）当that 从句与另一名词性从句并列作宾语时，that不能省；（C）当that作介词宾语时，that不可省掉。如：He judged that,because he was a child, he did not understand wine Everyone knew what happened and that she was worried. The reason lies in that she works harder than the others do. ③that从句作主语和宾语时，可以用it 来替换成以下几种结构表达。 (A)It is clear/certain/likely/true/surprising that… （B）It is a pity/shame/good idea/no wonder that ...（C）It is said/reported/ believed/known/thought/suggested that … （D）It seems/happens that。如： It happened that I went out last night. It is said that China will win in the World Cup. ④that和what的区别。 that 引导名词性从句时，在主从句中不以当任何句子成分，也没有任何含义；而what引导名词性从句时，在主从句中都要充当一定的句子成分，what可以分解成定语从句中的先行词+ 关系代词即常说的先行词+ that。如： It’s shame that he has made such a mistake. Do what he says. ⑤同位语从句与定语从句中that的区别。 同位语从句中的连词that只起连接作用，在从句中不担当任何句子成分；而定语从句中的关系代词that在句中做宾语或主语，宾语与先行词有修饰关系。如果句子是同位语从句，就应用连词that而不能用which.同位语从句一般放在表具体含义的名词后解释名词的含义或内容，如以下名词：news、fact、suggestion、truth、plan、belief、doubt、possibility、idea等，而定语从句只是对先行词的限定和修饰。如： They expressed the hope that they would come to visit China again.(同位语从句) The hope she expressed is that they would come to visit China again.（定语从句） 选择填空 1._____________ you have done might do harm to other people.

广东高考英语语法填空专题训练语法填空（每篇共10小题；每小题1.5分，每篇满分15分） 阅读下面短文，根据上下文填入适当的词语，或使用括号中的词语的适当形式填空， 并将答案填写在答题卡上标号为1—10的相应位置。 Passage (1) Cars are too expensive for many people around the world to own. Not only that, many cities are already full of traffic, and many country areas have rough roads. So 1 do people travel those distances that are too far to walk? They use public transportation. If you ride the subway or bus 2 you live, you can appreciate some of the benefits of public transportation. With many people 3 (share) one bus or train, there is less traffic and, more 4 （importance）, less pollution. Which of the types of mass transit 5 (describe) below are you familiar with? If a regular bus can hold dozens of people, imagine what a bus 6 (two) the size can hold! In Great Britain, there are many buses that are known as double-deckers (cars with two floors). Buses in Haiti are often very crowded. It’s not 7 (common) for passengers to actually sit on the rooftops. Buses are sometimes called “tap-taps”, because the 8 (ride) on the roof tap（敲击）when they want to be dropped off. Many large cities around the world take advantage of the space beneath the streets and run underground trains. People in Paris, Mexico City and Tokyo may use the subway system to get to school, to work, or to visit friends in other 9 (neighbor). Both the Japanese and French have developed High-speed trains to link various cities. While electric trains in North America average 130 kph, the French TGV (high-speed-train) is the world’s fastest, 10 (average) over 270 kph! Passage (2) Australia, the last continent, was discovered by ships 1 (belong) to some European nations in the seventeenth century. These nations were 2 (little) interested in changing it into a colony than in 3 (explore) it. As in the early history of the United States, it was the English 4 set up the settlements in Australia. This history and the geography of these two British colonies have some other things in common as well. Australia and the United States are about the same in size, and their western lands are both not rich 5 soil. It was on the eastern coast of Australia and America that the English first settled, and both colonies soon began to develop towards the west. However, this westward 6 (move) took place 7 because the English were searching for better land than the population was increasing. Settlements of the west part of both countries developed quickly after gold 8 (discover) in America in 1849 and in Australia two years later. Although the development of these two countries has a lot in common, there are some 9 (strike) differences as well. The United States gained its independence from England by revolution while Australia won its independence without having to go to war. Australia, 10 (like) the United States, was firstly turned into a colony by English prisoners and its economic development was in wheat growing and sheep raising. By 1922, for example, Australia had fifteen times more sheep than it had people or almost half as many sheep as there are people today in the United States. Australia and the United States have more in common with each other than either one has with most of the rest of the world.

To avoid knee pain,you can run on soft surfaces,do exercises to 68 (strength)your leg muscles(肌肉),avoid hills and get good running shoes. Running is cheap,easy and it's always 69 (energy).If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give 70 a try. B （2018全国二卷） Diets have changed in China — and so too has its top crop. Since 2011,the country 61 （grow）more corn than rice. Corn production has jumped nearly 125 percent over 62 past 25 years, while rice has increased only 7 percent. A taste for meat is 63 (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn's rise: The government encourages farmers to grow corn instead of rice 64 (improve) water quality. Corn uses less water 65 rice and creates less fertilizer(化肥) runoff. This switch has decreased 66 (pollute) in the country's major lakes and reservoirs and made drinking water safer for people. According to the World Bank, China accounts for about 30 percent of total 67 (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the government 68 (start) a soil-testing program 69 gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by million tons. That prevented the emission(排放) of million tons of carbon dioxide. China's approach to
