参考答案:
1.A
考查非谓语动词。句意:与我们的小公寓相比,叔叔的房子就像一座宫殿。“叔叔的房子”和“比较”之间是被动关系,用过去分词作状语,故选A。
一、过去分词作状语时的功能及位置
1. 过去分词作状语,修饰谓语动词,进一步说明谓语动词的动作和状态,即动作发生时的背景或状况,其逻辑主语通常就是句子的主语,且主语是过去分词动作的承受者,即过去分词表示的动作不是句子的主语发出的;过去分词与主语之间是动宾关系,即被动关系。如:
Although built thirty years ago, the house looks very beautiful. 尽管这座房子是30年前被建造的,它看起来依然很漂亮。
2. 过去分词短语作条件、原因及时间状语时,通常放在句首;作伴随、结果状语时,通常放在句末;作方式状语时,一般放在句末,有时也放在句首;作让步状语时,一般放在句首,有时也放在句末。如:
Given more time, he can do it better. 如果他被给予更多的时间,他就能把它做得更好。
二、 与状语从句的转换
1. 过去分词短语作时间状语,可转换为when, while或after等引导的状语从句。如:
Seen from the top of the hill, the park looks more beautiful.→When it is seen from the top of the hill, the park looks more beautiful. 从山上往下看,这座公园看起来更加漂亮。
2. 作条件状语,可转换为if, once或unless等引导的状语从句。如:
United we will stand; divided we will fall.→If we are united we will stand; if we are divided we will fall. 团结就是胜利;分裂必然失败。
3. 作原因状语,可转换为as, since或because等引导的状语从句。如:
Encouraged by the progress he has made, he works harder.→As he is encouraged by the progress he has made, he works harder. 由于受到所取得成绩的鼓舞,他工作更努力了。
4. 作让步状语,可转换为although, though或even if等引导的状语从句。如:
Although exhausted by the climb, we continued our journey.→Although we were exhausted by the climb, we continued our journey. 我们虽然爬得很累,但我们仍然继续我们的旅程。
5. 作方式状语,如有连词as if,就转换为as if引导的方式状语从句;若无连词,则转换为并列结构。如:
He began to cry as if bitten by a snake.→He began to cry as if he was bitten by a snake. 他大叫起来,好像被蛇咬了。
6. 作伴随状语,一般转换为并列结构。如:
Aunt Wu came in, followed by her daughter.→Aunt Wu came in, and (she) was followed by her daughter. 吴大娘走进来,(她)后面跟着她的女儿。
2.C
考查非谓语动词。句意:一听到警车的声音,强盗们惊慌地跑开了,留下一些被抢的钱。“留下”的逻辑主语是“强盗们”,它们之间是主动关系,用现在分词表示意料之中的结果,做结果状语,故选C。
3.B
考查非谓语动词。句意:看那边!有一条长长的蜿蜒小路通向那所房子。分析句式可知,这是个there be 句型,因此,此处用非谓语动词,path与lead是主动关系,因此用现在分词,故选B。
4.B
考查非谓语动词。句意:这种药尝起来非常难吃,被这个孩子扔掉了。主语是medicine,taste与主语是主动关系,而且taste是系动词无被动,因此用现在分词,故选B。
5.D
考查现在分词。句意:听见这个消息,她冲了出去,留在书本打开着放在桌子上,就消失在远处了。第一空leave与she构成主动关系,使用现在分词的形式。第二空the book与lie构成主动关系,还是使用现在分词的形式,open是形容词表示状态,lying open是宾语补足语,对the book进行补充说明。故D选项正确。
leave的几种用法
leave除了离开之外,还有以下几种用法:
一、作"留下"、"丢下"、"落下",常表示某物落在/忘在某地。
二、 表示"留给"、"交给",一般与介词with或to搭配。
三、 leave作使役动词,表示"使/ 让……保持某种状态"。
① 用形容词作宾语补足语
② 用不定式作宾语补足语
③ 用现在分词作宾语补足语
④ 用过去分词作宾语补足语
⑤ 还可用名词、介词短语等作宾语补足语
四、 leave的过去分词left,常用作后置定语,表示"剩下的"。
五、 leave还可作名词,表示"休假"、"假期"。
分析句子可知,leave作使役动词,表示"使/ 让……保持某种状态"。第一空leaving是一个现在分词做状语的用法,因为leave与he构成主动关系,就使用现在分词的形式。第二空the book与lie构成主动关系,还是使用现在分词的形式,open是一个形容词表示状态,Lying open是宾语补足语,对the book进行补充说明。故D选项正确。
6.B
考查动词用法。句意:你应该让你的孩子自己做作业。该题考查leave的用法。表示“让某人去做某事”,应该用leave的复合结构leave sb. to do sth.,没有leave sb. do结构;leave sb./sth. done意为“使得某人/物被……”。B选项正确。
7.B
考查非谓语动词。句意:他们中的一些人,在农村长大,从来没见过火车。分析句子可知,in rural villages部分为定语,修饰Some of them,与其为动宾关系,故用过去分词形式,同时也是表示一种状态,故选B。
8.B
考查动名词。句意:暴露于核辐射中甚至很短时间都会影响人体的基因。分析句子成分发现even for a short time是插入语,may influence是谓语,前面的部分应该是主语,be exposed to“暴露于”,要用动名词Being exposed to。故B选项正确。
9.A

10.B

12.D
考查非谓语动词。句意:下个月将发布的新智能手机可以保证卓越的音质,这将使那些耳机爱好者感到高兴。分析句子结构,can guarantee是谓语,空处作非谓语动词,release与逻辑主语The new smartphone之间是被动关系,且根据next month可知动作发生在将来,空处应用不定式的被动式作后置定语,即to be released。故选D项。
13.C
考查非谓语动词。句意:你能想到的解决这道难题的最好方法是什么?分析句子结构可知空格处为非谓语动词修饰the best way。the way to do sth做某事的方法为固定短语,动词不定式作定语修饰the best way。故选C。

16.A
考查不定式。句意:保罗不需要被强迫去学习。他总是努力工作,所以他总是取得进步。make sb. do sth.意为“让某人做某事”,“do sth.”是省略to的不定式,其变为被动语态时需将不定式符号to还原,因此为sb. be made to do,因此空格处是不定式to learn,故选A。

考查形容词、副词和动词不定式。句意:看到孩子们躺在房间里,他站在那里张大嘴巴,好像要说话。“with +名词/代词(宾语)+形容词(宾补)”with复合结构,形容词open (张开的)作宾补;副词wide (张得很大地)指具体的宽度,副词widely (广泛地、很大程度上地)是抽象的宽泛,主要表示距离远、范围大、地域广等,通常连用过去分词,用副词wide作状语,修饰形容词open;此处是as if从句“主语+系动词”结构,可省略主语he和系动词be,as if后面可接动词不定式表将要发生的动作。故选A项。
50.B
考查非谓语动词和副词。句意:人们认为,我们今天所知道的史诗是几代讲故事的人将材料传递下去的结果,直到最后,不知怎么的,有人把它写了出来。分析句子结构可知,第一空pass作非谓语,作介词of的宾语,故用动名词形式作宾语。第二空考查副词词义辨析,A.somewhat有点,稍微;B. somehow不知为什么;C.whatever无论什么;D. anyhow无论如何。分析句意,此处表达“不知怎么的”,应该用somehow。故选B项。
