1.In the recent coal mine accident,only 24 miners were rescued and 29 were left _C_ underground.
A.to be trapped B.being trapped C.trapped D.trapping
*leave的用法?是不是相当于be?
答:leave sth. done 在这里的用法相当于make sth. done ,让某事被做。只不过后者是要付出努力的‘让’,前者不需要付出努力的‘让’,只要离开,不用管,就可以了。比如leave the homework unfinished . The accident left 29 peoeple trapped underground. 事故是过去了,人还困在地下!上面的只是被动语态的说法:... and 29 were left trapped underground
译:在最近的一次煤矿事故中,只有24人获救,29人给困在地下。

2.When he struggled up,he felt his left ankle (sprained ),and found his left hand (swollen )and his nose (bleeding).
*这里done和doing要怎么区别使用啊?
答:和上句中的leave, make一样,feel 动词后常跟复合宾语,宾语补足语可以是过去分词或现在分词或形容词。看它与前面宾语在逻辑上的关系而定,主动用现在分词 feel sb. doing sth. ,被动用过去分词 feel sth. done
ankle是被扭(被动的,用过去分词sprained0, nose 是在出血(主动的,用bleeding)hand is swollen (swollen这里是形容词)
3.__C____ confidence in yourself is the biggest barrier _____ greater progress in your work.
A.Lacking of,to making
B.Lack of,to make
C.Lack of,to making
D.The lack of,to make
*我选了D。请解释一下 还有,顺便问一下什么叫介词 to
答:to有不定式符号to和介词to之分,前者后跟动词原形,如to make, 后跟名词或相当于名词的动名词。这时的to解释为“对。。。”,“到。。。”,常见的容易误以为是不定式符号的几个:look forward to ..., be used to ...., stick to ....要记住。
be a barrier to (doing )sth. 意为“对(做)某事来说是一个障碍。这个to就是介词,容易误以为是不定式。Lack可作及物动词,可作名词。如果A没有 of, 则Lacking confidence 作为动名词短语也是可以作主语的。BD的主要错误在于后一空。

.In the recent coal mine accident,only 24 miners
were rescued and 29 were left _C_ underground.
A.to be trapped
B.being trapped
C.trapped
D.trapping
*leave的用法?是不是相当于be?
答:应该选C。 这是leave sb/sth +宾语补足语 意思是“使...处于某种状态”
用过去分词作宾补表示被动,29 were left trapped underground意思是:29人被困在地下。
也可以用形容词、名词等作宾补。又如:
Who left the door open?
His parents died, leaving him an orphan.
2.When he struggled up,he felt his left ankle
_sprained__,and found his left hand _swollen_ and
his nose __bleeding__.
*这里done和doing要怎么区别使用啊?
这是find sb/sth doing/done/adj的用法。
用过去分词宾补表示宾语是分词动作的承受者;用现在分词作宾补表示宾语是分词动作的发出者;用形容词作宾补表示状态。
翻译:当他挣扎着起来后发现左脚踝被扭伤了,而且左手肿了(swollen是形容词表示状态),鼻子在流血。
3.__C____ confidence in yourself is the biggest

barrier _____ greater progress in your work.
A.Lacking of,to making
B.Lack of,to make
C.Lack of,to making
D.The lack of,to make
*我选了D。请解释一下 还有,顺便问一下什么叫介词
to
答:barrier意思是障碍, 隔阂
例如:Lack of confidence is the biggest barrier to investment in the region.
缺乏信心是在这一地区投资的最大障碍。
lack作名词时,后接of 再接名词。
介词是一种用来表示词与词、词与句之间的关系的虚词,在句中不能单独作句子成分。介词后面一般有名词代词或相当于名词的其他词类,短语或从句作它的宾语。介词和它的宾语构成介词词组,在句中作状语,表语,补语或介词宾语。

祝你学习愉快~
介词常用的有:in, of, to, by

这个题后面的trapped是过去分词作宾语补语,只不过这里是被动语态不太容易看出来。换成主动时态就是sht leave 29 miners trapped underground.trapped是修饰miners的
这里用done或者doing主要是看动作时被动还是主动还有时态。像发现鼻子正在流血就是doing.不能说被流血。
这个题我也选D吧。介词to没有什么特别的吧。

另外我觉得第三题,重点在于知道lack of sth是一种习惯用法lack作为名词应该没有前面加the的习惯。后面的把to 当做介词就好理解了。看了几个例句都是这样:Lack of evidence resulted in their acquittal.因证据不足而宣判他们无罪。
Fixed wages and lack of promotion act as a disincentive to employees.
工资固定又无晋升机会遏制了雇员的积极性。
The accused got off/escaped scot-free because of lack of evidence.
由於证据不足,被告未受惩罚。

1.In the recent coal mine accident,only 24 miners were rescued and 29 were left -trapped- underground.
这里were(be)+left(过去分词)构成被动结构,之后的trapped underground为过去分词,表示本分句主语“29”的状态。

2.When he struggled up,he felt his left ankle _sprained__,and found his left hand _swollen_ and his nose __bleeding__.
*这里done和doing要怎么区别使用啊?
done和doing都属于非谓语动词,doing叫现在分词,主要表示主动与进行done为过去分词,表示被动与完成;
主被动是相对于分词与其逻辑主语之间所形成的关系,而进行与完成则是相对于句子谓语动词状态而言
例如:he felt his left ankle _sprained,这个分句中,sprain为及物动词,因为它与它的逻辑主语(非谓语动词动作的执行者或承受着,不一定是句子主语)his left ankle之间是动宾(即被动)关系。He sprained his left ankle.=His left anke was sprained.
he felt his nose bleeding. 这个分句中,bleed为不及物动词,bleeding现在分词表示“流血”这个动作与felt(过去时)同时进行。
要注意的是:一般,及物动词主要强调主被动关系,而不及物动词则主要表示动作完成或进行的状态

3. Lack of confidence in yourself is the biggest barrier to making greater progress in your work.
第一个空的lack前没有定冠词the存在的必要,详细可参阅the的具体用法;
to可以做介词,在许多短语里存在,之后只接名词、代词或doing(动名词),如be addicted to sth, look forward to doing sth, etc. 具体如下:
一:表示相对,针对 be strange to
二:表示对比,比较
1:以-ior结尾的形容词,后接介词to表示比较 senior,junior
2: 一些本身就含有比较或比拟意思的形容词 A is similar to B in many ways.
3:表示一些先后顺序的形容词 they returned to their hometown
4: to也偶尔出现在个别动词之后,与动词形成固定词组,表示比较 compare to sth.
5: to与及个别的名词构成比较之意, Going to an under water concert is a great alternative to going to dinner.
三: 表示修饰关系
1: 表示回复,反应意思的词 answer to question
2: 表示建筑构件的词汇 the approach to science
3: 表示人物职位和官衔的词 assistant to manager
4: 表示权利和许可的词汇 Everyone has an equal right to
5: 表示栅栏或障碍的词汇 the barrier to progress
6: 表示与书籍,文本相关的词 introduction to passage
7: 表示恭喜或是祝贺 Let’s drink to Dick’s success in business
8: 另外还有一些名词符合这种用法,有的具有两者息息相关,缺一不可的含义 guide to action
四: to还具有依据,伴随,和着节奏的含义 sing to piano
(一):表示相关联,相连接 be related to
(二):表示反对和赞同
1:to引导的表示反对,抗拒,对抗意义的词组 be opposed to
2: to引导的表示同意,赞同意义的词组 The employer consented to give him a salary raise
3: 表示投降,屈服,服从的含义 confess to
五: 表示趋势或倾向, tend to
六: 表示对事情的坚持与执着 He still holds on to his original views
七: 表示约束,局限 limit to
八: 表示一种习惯或是一种适应性 get (be) to
九: 表示起因和原由 due to
十: 表示目的或结果 lead to

1、leave + n. + v-ed是固定用法
2、当动词与名词是动宾关系时,用done,如sprain his left ankle
,sprain是及物动词, his left ankle 做sprain的宾语;当名词与动词是主谓关系时,用doing,如 his nose bleed,his nose 做主语,bleed是不及物动词,做谓语
3、我选C,lack本身即可作名词,与of连用表示缺乏某物,不必加the 。当to用作介词时,其后跟名词或动名词 ,这是它用作介词的标志。
