negative消极的,负面的;brave勇敢的;fresh新鲜的;open-minded思想开放的,开明的。后句提到“We should keep positive every day”,说明空格处需要填入“积极”的反向对应词,只有negative符合句意逻辑。
33.A
【解析】句意:许多野生动物正处于危险之中。我们必须采取行动保护它们。
at risk处于危险中;in public公开地;by accident偶然地;for free免费地。根据“must take action to protect them”可知,野生动物面临危险,应用at risk。
34.D
【解析】句意:这是我一生中最糟糕的一天。希望一切能尽快好转。
bad糟糕的(原级);worse更糟糕的(比较级);badly糟糕地(副词);worst最糟糕的(最高级)。根据范围限定“in my life”可知要用形容词最高级,应填worst。

weigh (动词) 称重;weight (名词) 重量;weighing (动名词) 称重;weighed(过去分词/过去式) 称重。 形容词light后需要名词作宾语,light weight表示“轻便、重量轻的”,weight符合语境。
36.A
【解析】句意:汤姆看到志愿者们辛苦干活时,主动帮忙清理公园里的塑料垃圾。
offer to do sth.“主动提出去做某事”,从句动词saw是一般过去时,整句描述过去发生的事,主句谓语要用过去式offered。
37.B
【解析】句意:学生们正在做一项科学实验,来测试塑料降解需要多长时间。
此处需要用形容词修饰名词experiment,应填scientific。
38.B
【解析】句意:我们需要弄清楚为什么一些沿海地区的塑料污染更严重。
find找到;find out查明,弄清;look for寻找;discover发现。空后“why plastic pollution is more serious in some coastal areas”是宾语从句,look for不接从句,这里是查明塑料污染严重的原因,discover语义不符,find体现不了“查明”的句意。应填find out。
39.D
【解析】句意:地上有两个瓶子。请把它们捡起来放进回收箱。
pick up“捡起”,是动副短语,代词作宾语时要放在中间,而此处代词指代前句的“bottles”,应用复数them,故选用pick them up。
40.C

since then从那以来,常与现在完成时连用;from then on从那时起,多与一般过去时连用;just now刚才,常与一般过去时连用;at once立刻、马上,常与一般现在时或一般过去时连用。此处句中“has become”为现在完成时,需要搭配表示从过去持续到现在的时间状语,应填since then。
42.B

by mistake错误地,侧重意外偶然发生,不含“认错事物”的含义;by accident意外地,侧重分辨不清而搞错;on purpose故意地;in fact事实上,根据“it thought it was food”可知,是鲸鱼错误地判断把塑料袋当成食物,故选B。
43.B
【解析】句意:一些奶牛把塑料袋错当成草,误吃了它们。
mistake...as错误搭配,无此用法;mistake...for把……误认为……;take...as把……看作……;think...for错误搭配,无此用法。此处需要表达错认的含义,与句中by mistake呼应,故选B。
44.C
【解析】句意:塑料在很多领域取代了木材,因为它更便宜。
replaced with正确用法为“be replaced with”,表示“被……替代”,本句主语是Plastic,主动语态下不能直接使用;took place意为“发生”,不符合语境;replaced作及物动词时,“A replaced B”表示“A取代B”,符合“塑料取代木材”的语义和主动语态的句子结构;instead of是介词短语,不能作谓语动词,故选C。

considered as(缺少be动词,不能单独作谓语);was considered as(一般过去时的被动语态,被当作);thinks of(一般现在时,主语是人,主语不能是材料);is thought of(一般现在时,和后面was时态不一致)。句子里it was表明时态为一般过去时,material和词组是被动关系,因此选用was considered as。
48.A
【解析】句意:把塑料塑造成不同的造型很容易,因此塑料很快就流行开来了
easy容易的,形容词;easily容易地,副词;difficulty困难,名词;hard困难的,形容词。此处使用句型It was +形容词+ to do sth.,It作形式主语,空格处需用形容词,根据“shape plastic into different things”可知此处表示易塑形的。
49.C
【解析】句意:塑料在1870年左右被发明,它极大地改变了人们的生活。
invent“发明”,是动词,根据主语“plastic”和谓语“invent”可知,二者是被动关系,应用被动语态,且由“around 1870”可知时态为一般过去时,一般过去时的被动语态结构是was invented。
50.C
【解析】句意:下列哪个单词的构成方式与“handbag”相同?
handbag意为“手提包”,是由hand和bag组成的合成词。careless粗心的;instruction说明;wartime战时;monitor班长。wartime是由war和time组成的合成词,与handbag构成方式相同。
51.B
【解析】句意:这条河太脏了,我们看不见里面的鱼。我们必须采取行动清理它。
clear清澈的;dirty脏的;deep深的;wide宽的。后半句“We must take action to clean it”说明河水存在污染问题,dirty符合语境,其余单词均无法对应后文清理河水的描述,故选B。
52.C

pollute污染(动词);polluted受污染的(形容词或动词过去式); pollution污染(名词); polluting污染(现在分词)。定冠词the后面需要接名词,pollution符合。
53.A
【解析】句意:当塑料在1870年左右被发明时,它被称为“环境英雄”,因为它又轻又便宜。
hero英雄;problem问题;waste废物;pollution污染。根据后文 “because it was light and cheap”(因为它又轻又便宜),可知当时塑料被视为有益的事物,故用褒义词汇。hero符合题意。

57.C
【解析】句意:——我不敢过来。你的狗有点吓到我!——别担心。它被拴在树上了。
主语 It与谓语动词tie是动宾关系,所以用被动语态。根据”Don’t worry.”可推知,该句表示现在的状态,所以用一般现在时的被动语态。
58.D

Clean it up打扫干净;Watch your step注意脚下;Give it up放弃吧; Come on out出来吧,加油,别退缩,在口语中常用来鼓励别人。根据“I’m too shy to give that speech”及“We’re all here to support you.”可推知,此处用“Come on out”鼓励对方上台演讲。
59.A
【解析】句意:昨晚,我的邻居们一直大声争吵到半夜,所以我无法入睡。
loudly大声地;quietly安静地;suddenly突然地;happily开心地。后文“I couldn’t fall asleep我无法入睡”,表明邻居的争吵声很大,影响睡眠。loudly符合语境。
60.A

cheap便宜的;long长的;expensive昂贵的;colourful多彩的。根据答语中的“save money”可知,答语解释了他们想省钱买新车,这与前句中他们打算度过一个“便宜的”假期在逻辑上完全吻合,应填cheap。

65.B
【解析】句意:单词friendly是在名词friend后添加后缀-ly构成的,后缀-ly常把名词变为形容词。
friend为名词,加上-ly后friendly是形容词;形容词加-ly才会变成副词,名词加-ly一般构成形容词。
66.B

disable使丧失能力;unable不能的;enable使能够;ability能力。able意为“能够的”,是形容词,其反义词需加否定前缀un-,构成unable。
67.B

72.C
【解析】句意:总之,我的家庭不是很环保。我们仍然使用太多的塑料产品。
is是;are是;isn’t不是;aren’t不是。后句“We still use too many plastic products.”说明家庭并不环保,需用否定形式;“very green”用来评价一整个家庭的生活方式、整体环保水平,描述集体属性,只能当单数。应填isn’t。
73.B
【解析】句意:为了过上更环保的生活,我们应当避免使用塑料袋。
use more更多使用;avoid避免;burn燃烧;throw away扔掉。句首“To live a greener life”点明绿色环保的核心要求,减少塑料袋使用是环保举措,avoid符合该句语义。
74.A

more often更频繁;most often最频繁;often经常;oftener无此变形。句中than是比较级标志词,often为多音节副词,比较级需用more修饰,most often是最高级,often为原级,oftener为错误变形,故选A。

77.B
