5．句2中的how在从句中作________。
Keys: 1．主语 2．主语 3．是否 4．that 5．状语
□主语从句
本单元语法主要介绍的是主语从句，主语从句是名词性从句的一种，在复合句中作主语，相当于名词。主语从句的位置可以在句首，也可以用it作形式主语，主语从句放在后面。
一、主语从句的基本用法
(一)主语从句的引导词
类别 例词 用法
从属连词 that，whether 在从句中均不作成分，只起连接作用；that无实义，whether表示“是否”
连接代词 who，what，which，whoever，whatever等 在从句中作主语、宾语、表语、定语等成分
连接副词 when，where，how，why等 在从句中作时间、地点、方式、原因状语等成分
Whoever breaks this law deserves a fine.
触犯本法者应予以罚款。
Whichever (of you) comes in first will receive a prize.
(你们中)谁先进来谁得奖。
【名师点睛】
主语从句中连接词的选择技巧
(1)根据连接词在从句中所作的语法成分。
(2)根据连接词在从句中的意义。
(二)it作形式主语
为保持句子平衡，常把主语从句后置，而用形式主语it代替。it作形式主语时常用于以下句型：
句型 说明
It＋系动词＋形容词＋主语从句 常用于此句型的形容词有important，natural，(un)likely，possible，necessary，wrong等。
It＋系动词＋名词＋主语从句 常用于此句型的名词有fact，idea，honour，question，pity等。
句型 说明
It＋系动词＋过去分词＋主语从句 常用于此句型的过去分词有known，proved/ proven，said，decided，suggested，thought等。
It＋不及物动词＋主语从句 常用于此句型的不及物动词有appear，happen，seem，occur，matter等。
It’s possible that he has been to Beijing.
他有可能去过北京。
It’s a pity that you didn’t attend the meeting.
你没参加这次会议太可惜了。
It seems that it is going to rain.
看起来好像要下雨。
It is important that he (should) know about this.
重要的是他应该知道此事。
It is suggested that the meeting be put off.
有人建议会议延期召开。
【名师点睛】
(1)在“It＋be＋过去分词＋主语从句”结构中，过去分词若为suggested/ordered/required/advised等，主语从句中的谓语用“(should) do”。
(2)在“It＋be＋形容词＋主语从句”结构中，若形容词为important/necessary/strange等，主语从句中的谓语用“(should) do”。
二、主语从句中应注意的问题
1．从句要用陈述语序
How he succeeded is still a puzzle.
他是如何成功的仍然是个谜。
2．主谓一致
(1)单个主语从句作主语时，主句的谓语一般用单数形式。
Where he will get a job after graduation has puzzled him much.
毕业后去哪里找一份工作使他很困惑。
(2)what引导主语从句时，有时主句谓语动词的数应与主句中作表语的名词的数保持一致。
What the school needs most are books.
这所学校最需要的是书。
(3)如果由and连接两个或两个以上的主语从句作主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句时，谓语动词用单数。
When they will start and where they will go have not been decided yet.
他们将在什么时候动身以及要去哪里还没定下来。
When and where they will hold the meeting is not clear.

But for a student，the military training is often considered boring because he just follows a dull way of exercise，for example，standing in the sun or running for a long time.
The exercise is too much for some students who are weak physically.Though asked to do basic exercise，students should be permitted to do it based on their physical conditions.
In a word，it is necessary for students to be trained，but the forms of training should be interesting and reasonable.(共16张PPT)

①The crops we produce in the UK and around the world could change with climate. The weather is an important part in farming and changes in temperature will strongly affect crop growth.
②For the UK，temperature rises are likely to mean the crops normally growing in the south of the country will be able to be grown further north. The UK believes there will be a shift northwards of between 200 and 300 kilometres for every degree of warming.
Due to an increase in drought and heat waves，the types of crops grown in the UK will have to change，which doesn’t have to be a bad thing for us. Products which haven’t been farmed over here before could all provide new business for farmers — certainly in the southeast.
However，if farming practices do change in this country，procedures will have to be put in place beforehand as introducing something new of farmland involves a lot of preparation.
Also，irrigation(灌溉) systems may need to be improved so rain from winter can be stored for the summer as it is hotter.
Researchers have found that pests，such as aphids(蚜虫)，are starting to hatch(孵化) earlier in the year. In the last 10－15 years they’ve been arriving in springtime and the population of aphids appears to be growing too.
Aphids are a real problem as they can cause much damage to crops and if they’re arriving earlier in the year，they can get the produce when it’s very fragile—causing more damage than they used to.
○课标词汇
normally /'n m li/ adv. 通常；正常地
shift / ft/ n．改变；转移；转换；轮班
v. (使)移动；(使)转移；(使)转换到；(使)改变意见(或信仰等)
drought /dra t/ n. 干旱；旱灾
procedure /pr 'si d (r)/ n. 手续；程序；步骤
beforehand /b 'f h nd/ adv. 事先；预先 adj. 提前的；预先准备好的
fragile /'fr d a l/ adj. 易碎的；易损的；不牢固的；易被摧毁的
○重点短语
be likely to do sth. 可能做某事
due to 由于
provide...for... 向……供给……
in place 在对的位置；在适当的位置
cause much damage to... 对……造成很大损害
○句型精析
①The crops we produce in the UK and around the world could change with climate.
分析：该句为复合句。 “we produce...”为定语从句，修饰先行词crops。
译文：我们在英国和世界各地生产的作物可能会随着气候而变化。
②For the UK，temperature rises are likely to mean the crops normally growing in the south of the country will be able to be grown further north.
分析：该句为复合句。 动词mean后是省略了that的宾语从句，其中现在分词短语“normally growing in the south of the country”作名词crops的后置定语。
译文：对于英国来说，气温上升可能意味着原本生长在该国南部的作物将可以种植在更北的地方。
