_____ the project as planned, we’ll have to work two more hours a day.
A. Completing B. Complete
C. Completed D. To complete

D
后半句中已有谓语，选填非谓语动词。
“完成”与we是主动关系，排除C
因为是表目的，所以选D
为了按照计划完成这个工程/项目，我们不得不每天多工作2小时。
非谓语在句子中作目的状语。

动词不定式作目的状语既可用“to＋动词原形”表示, 也可用“in order to＋动词原形”或“so as to＋动词原形”表示。例如:

①He came here to borrow my bike. 他到这里来借我的自行车。

②The rich woman spent all her time and all her money in order to be well dressed. 这位富妇人为了穿得漂亮, 她不惜花掉她全部的时间和金钱。

③Igotup early so as to be in time for morning exercises. 我起得很早, 以便于及时做早操。

使用它们时应注意以下要点:

一、用“in order to ＋动词原形”比“to＋动词原形”作目的状语时语气较强而且文体较正式。例如:

People there killed many lions in order to protect the deer. 那里的人们为了保护鹿, 杀掉了许多狮子。

二、一般来讲, “in order to ＋动词原形”与“so as to ＋动词原形”可以互换。但是, 如果不定式兼有“结果”的涵义时, 一般应用“so as to ＋动词原形”。例如:

Ishallgo on working late today soas to be free tomorrow. 我今天要工作得晚些, 明天就可以没事了。

三、“in order to..."通常可以放在句首, 使其表示的目的更加明显; “so asto... 也可放在句首作目的状语”。例如:

In order to get there before eight I started early. 为了在八点以前赶到那里, 我很早就动身了。

So as to make a study on kangaroos, he came to Australia. 为了研究大袋鼠, 他来到了澳大利亚。

四、当不定式的否定式作目的状语时, 一般用“in order not to..."或“so as not to...", 不用“not to...", 因为后者是结果状语。试比较:

I''''m going to get up now in order not to（so as not to）miss the early bus. 为了不误早班公共汽车, 我现在得起床。

He came in quietly in order not to（so as not to）wake the child. 他轻轻地走了进来, 以免吵醒孩子。

He must be deaf not to hear what I have said. 连我说的话都听不见, 他一定是聋了。（表结果）

五、在“enough to..., only to..., too... to..."等结果中的不定式皆表结果, 但在“so＋adj. ／adv. as to..."结构中的不定式既可表目的, 又可表结果, 判断二者时, 一要看句子意思和上下文, 二要看语言环境才能确定。例如:

The boy is old enough to go to school. 那孩子到了上学的年龄。

He lifted a rock only to drop it on

his own feet. 他搬起石头砸了自己的脚。

The tea is too hotto drink. 茶太热, 不能喝。

Ispoke so loudly as to be heard by all. 这句话可以理解为:

A. I spoke so loudly that I could be heard by all. 我大声讲话, 以便大家都能听到。（表目的）

B. I spoke so loudly that I would be heard by all. 我说得很大声, 以致人人都听得到。（表结果）

但: The house is so high and narrow as to resmeble a tower. 这房子又高又窄, 象一座塔。（显然是结果状语）

六、在非正式用语中, 尤其在祈使句中, “try to..."结构通常可以用“try and..."来代替。例如:

Try to finish the work in a week. ＝Try and finish the work in a week. 争取一周内完成这项工作。

但在try或try的否定式后只能用不定式作目的状语。例如:

He always tries to study hard. 不可说: He always tries and studies hard.

He didn''''t try to study hard. 不可说: He didn''''t try and study hard.

而动词come, go等没有这种规定, 用不定式作目的状语和用“and..."都可以。例如:

I went to have a drink with him yesterday. ＝I went and had a drink with him yesterday.

He went to tell his parents what had happened. ＝He went and told his parents what had happened.

刍议“伴随状语”


近几年的高考英语中，“伴随状语”作为一个考点经常出现。笔者就能作“伴随状语”的几种情况归纳如下，供参考。


一、with复合结构做伴随状语：


由“with ＋宾语＋宾补”构成的复合结构，在句中可作状语，表示伴随。这一结构中的宾语补足语可由现在分词、过去分词、形容词、副词或介词短语等来充当。例如：


1．With production up by 60％，the company has had another excellent year．产量增涨了60％，公司又是一个盈利年。


2．He soon fell asleep with the candlestillburning．蜡烛还亮着，他很快就睡着了。


3．She sat there alone with her eyes filledwith tears．他独自一人坐在那儿，眼里充满了泪水。


二、独立主格结构做伴随状语：


独立主格结构是由一个名词或代词（作为该短语结构的逻辑主语），加上一个分词、形容词、副词、动词不定式或介词短语（作为该短语结构的逻辑谓语）构成。该从属结构主要起状语作用，相当于一个状语从句。故独立主格结构也可做伴随状语。例如：


1．Mr．Smith flew to New York thismorning，his assistant to join him there this Sat-urday．今天早上史密斯先生坐飞机去了美国，他的秘书星期六和他在那儿见面。


2．He was lying on the grass，his handscrossed under his head．他躺在草地上，头枕双手。


3．He stood on the deck，pipe in mouth．他站在甲板上，嘴里叼着烟斗。


三、分词短语做伴随状语：


现在分词短语和过去分词短语都可以做伴随状语，现在分词短语表示与主句的主语在逻辑上有主谓关系，即表主动意义；而过去分词短语则表示与主句的主语在逻辑上是动宾关系，即被动意义。例如：


1．“Can't you read？”Mary said angrily pointing to thenotice．玛丽生气地指着通知说：“难道你不识字吗？”


2．He sent me an e-mail hoping to get further information．他给我发了一封电子邮件，希望得到更多信息。


3．He hurried to the hall，followed by two guards．他匆忙进了大厅，后面跟着两个警卫。


四、形容词短语做伴随状语：


形容词短语做伴随状语时，通常表状态。例如：


1．Full of apologies，the manager approached us．经理向我们走来，嘴里不停地说着抱歉的话。


2．He was too excited，unable to say a word．他太激动了，一句话也说不出来。


3．He stared at the footprint，full offear．他盯着脚印，满心恐惧。


五、单个形容词做伴随状语：


单个形容词做伴随状语也表示状态，不表动作。例如：


1．He sat there，silent．他一声不响地坐在那儿。


2．Breathless，she rushed in throughthe back door．穿过后门，他气喘吁吁地冲了进来。


3．He went to bed，coldand hungry．他又冷又饿地上床睡觉了。
