Researchers from Georgia Tech say that they have come up with a low-cost device that gets around this problem: a smart keyboard.

1.Enviable as the cool kids may have seemed, Dr. Prinstein’s studies show unpleasant consequences.
2.It clearly showed that while likability can lead to healthy adjustment, high status has just the opposite effect on us.
“We found that the least well-liked teens had become more aggressive over time toward their classmates. But so had those who were high in status.
In analyzing his and other research，Dr. Prinstein came to another conclusion: Not only is likability related to positive life outcomes, but it is also responsible for those outcomes, too. "

1.主语从句
作句子主语的从句叫主语从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用。
例如：
What he wants to tell us is not clear.
Who will win the match is still unknown
It is known to us how he became a writer.
Where the English evening will be held has not yet been announced.
That he finished writing the composition in such a short time surprised us all.
Whether we will go for an outing tomorrow remains unknown.
Who will be our monitor hasn't been decided yet.
Whom we must study for is a question of great importance.
What caused the accident remains unknown.
Whatever you did is right.
Who the watch belongs to was lost is unknown.
What we need is time.
What we need are good doctors.

在demand、order、suggest、decide、insist, desire, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。例如：

宾语从句的语序
5
（1）宾语从句始终用 。疑问句当宾语时，“连接词+主语+谓语+其他”。连接词在从句中作主语时，从句语序“连接词+谓语+其他”。当宾语从句为感叹句时，仍采用感叹句语序。

陈述语序
宾语从句的时态
6
宾语从句的时态可以记忆为：“主现从不限，主过从必过，真理终用现”。
（1）主现从不限：如果主句的谓语动词是一般现在时，从句谓语可根据需要选择相应的时态。
Do you know when the ancient Olympic games (begin)
（1）主过从必过：如果主句的谓语动词是一般过去时，从句的谓语只能选择过去的某一种时态。

He said they (have) a meeting at that time.

（3）真理终用现：如果宾语从句表示的是客观事实、普遍真理、自然现象等，不管主句用什么时态，从句都用一般现在时。
The teacher said ligt (travel) fast than sound.
The teacher said that the moon (go) around the earth yesterday.
3.表语从句
表语从句的连接词

表语从句的连接词

表语从句用虚拟语气的情况
2
如果主句的主语是advice,demand,order,suggestion,requirement,ruquest,command等，表语从句用虚拟语气，结构是“（should）+动词原形
His suggestion is that we ______(set) off at once.
表语从句中的虚拟语气：as if， as though
1、与现在事实相反，从句用过去式
-She looks as if she _____(be) angry.看她的表情，好像生气了似的。(其实没有生气)
-Ming is now in a new jacket. He looks as if he _______(be) an American boy.小明穿了一件新夹克，看起来像是个美国男孩。(实际小明还是中国男孩)
2、与过去事实相反，从句用过去完成时态had been 或 had done

- It appears as if technology ___________(solve) the problem in the future.看起来技术似乎会在未来解决这个问题。(事实上不一定，也可能根本解决不了)
as if 或 as though 引导的表语从句，有时当从句中所说的内容属于假设情况时，要用虚拟语气。而虚拟语气我们之前讲过通常从现在、过去、将来三个时间上来进行区分：
名词性从句
名词性从句中的虚拟语气总结：表示请求、命令、建议等
表示建议、请求、命令等词的虚拟语气，后面用虚拟语气（should）do。注意：经常会把 Should 省略。
主语从句：

4.同位语从句
同位语就是用不同的方式把一个概念再说一遍，用逗号隔开。
同位语从句是用一个从句充当同位语，一般在句中修饰抽象的名词
跟同位语从句的名词
1
同位语从句用来说明某些名词的实际内容或对该名词进一步解释。可以跟同位语从句的主要是一些抽象名词：
I have no idea when we will have a long holiday.
idea、plan、fact、hope、news、theory、truth、information、doubt suggestion、belief、thought、question、conclusion、knowledge、opinion、thought、message、words、possibility
可用于同位语从句的连词有 that（无意义），whether（是否），连接副词 how,when,where等，if,which 不能引导同从

2
同位语从句可用that,whether,which,who,what,when, where, why,how等引导
There is some doubt whether he will come.
He must answer the question whether he agrees to it or not.
同位语从句中的虚拟语气
3
当主语是advice，proposal，request，suggestion等词时，同位语从句要用”（should）+动词原形
The suggestion came from the chairman the
rule (be) adopted.
有时同位语从句可以不紧跟在说明的名词后面，而被别的词隔开。 如：
Several years later，word came that Napoleon himself was coming to inspect them． 几年以后，有消息传来说拿破仑要亲自视 察他们。
The thought came to him that maybe the enemy had fled the city． 他突然想起可能敌人已经逃出城了。
