基础达标
一、用所给单词的正确形式填空
1 ．October 1st is our （nation）Day.
2 ．Watching football matches gave us great （please）.
3 ．First Emperor of the Qin Dynasty was one of the （ruler）in the old days. 4 ．Many countries in the world are looking forward to （trade）with China.
5 ．The mother found her daughter had a （music）talent.
【答案】
1 ．National 2 ．pleasure 3 ．rulers 4 ．trading 5 ．musical
【详解】
1 ．句意：十月一日是我们的国庆节。
修饰名词 day,要用 nation 的形容词形式 national。National Day 意为“ 国庆节”,表示节日的每
个单词的首字母都要大写。故填 National。
2 ．句意：看足球比赛给了我们很大的乐趣。
空格处作 gave 的宾语, 因此用 please 的名词形式 pleasure 意思是“乐趣” 。根据题意，故填
pleasure。
3 ．句意：秦始皇是古代的统治者之一。
“one of the+名词复数”表示……之一；ruler 名词，统治者，这里用复数形式。根据句意，故
填 rulers。
4 ．句意：世界上许多国家都期待着与中国进行贸易。
trade 动词,意为“做买卖；从事贸易” ；look forward to 意为“渴望；盼望”,其中 to 是介词,后面
接名词、代词或动词-ing 形式， ,故填 trading。
5 ．句意：母亲发现她女儿有音乐天赋。
由空格后的名词可知空格处需要填一个形容词作定语。music 的形容词形式是 musical。故填
musical。
二、完成句子（每空一词）
6 ．毫无疑问，你越努力，就越幸运。
, the harder you work, the luckier you will be.
【答案】 Without doubt
【详解】中英文对照可知填“毫无疑问”；without doubt 意思为“毫无疑问，无可置疑” ，固定
搭配。此处作状语，且句首单词的首字母需大写。故填 Without； doubt。
7 ．2003 年神舟五号把中国的第一位宇航员送入太空。
In 2003, China’s first astronaut space on Shenzhou 5.
【答案】 was sent into
【详解】根据主语“astronaut”和“2003”可知，本句应使用一般过去时的被动语态“was/were+ 过去分词” 。主语 astronaut 为单数，所以 be 动词使用 was ；send“发送” ，过去分词为 sent；
into“进入” 。故填 was ；sent ；into。
8 ．三分之二的牛奶被他喝了。
the milk by him.
【答案】 Two thirds of was drunk
【详解】根据题干可知， two thirds of 表示“三分之二的” ；drink“喝” ，动词，此处是被动语 态结构，谓语结构是 be done，动作已发生了，句子应用一般过去时的被动语态，主语是不
可数名词 milk ，be 动词用 was ，drink 的过去分词是 drunk。故填 Two；thirds；of；was；
drunk。
9 ．当地铁一号线完成建设旅客出行毫无疑问将会更加便捷。
When Subway Line 1 is completed, passengers will feel more convenient to
travel around.
【答案】without doubt
【详解】根据英汉对照，缺乏对“毫无疑问” 的表达， without doubt 介词短语，意为“毫无疑
问” ，在此用作状语，放在主语和情态动词后谓语动词前。故填 without doubt。
10 ．晚餐闻起来好但尝起来奇怪。
The dinner but .
【答案】 smells good tastes strange
【详解】 “ 闻起来”是 smell ，“尝起来”是 taste ，都是感官动词，后面应跟形容词。 “好的”是 good，“奇怪的”是 strange，都是形容词。主语 The dinner 是单数， 且 smell 与 taste 并列， 都
应用“三单”形式。故填 smells；good；tastes ；strange。
能力提升
三、单项选择
11 ．Computers have had a great influence on learning methods since they into schools.
A ．introduce B ．introduced C ．are introduced D ．were introduced
【答案】D
【详解】句意：自从计算机被引入学校以来，它们对学习方法产生了很大的影响。
考查时态和语态。 since 引导的时间状语从句，从句用一般过去时，主语“they”指代
“Computers”，与谓语动词 introduce“引进”之间是动宾关系，所以用一般过去时的被动语态
（were done）。故选 D。
12 ．I really don’t want to know the secret. I only found it .
A ．by an accident B ．by the way C ．by myself D ．by accident
【答案】D
【详解】句意：我真的不想知道这个秘密。 我只是偶然发现它的。
考查介词短语。 by an accident 表达错误； by the way 顺便说一下； by myself 我独自地； by accident 偶然地。根据“I really don’t want to know the secret.”我真的不想知道这个秘密， 可推
知我只是偶然发现的，因此 by accident 符合语境。故选 D。
13 ． is said that there will be rain tomorrow.
A ．It B ．This C ．That D ．One
【答案】A
【详解】句意：据说明天有雨。
考查代词辨析。 it 它；this 这个；that 那个；one 一个。固定句式：It is said that+从句，表示
“据说” ，故选 A。
14 ．They have saved a lot of time and money since the new robots to their factory.
A ．are brought B ．were brought
C ．brought D ．bring
【答案】B
【详解】句意：自从新机器人被带到他们的工厂以来，他们节省了很多时间和金钱。
考查被动语态。分析从句主语和动词 bring 可知它们之间是被动关系， 应用被动语态， 题干 是复合句， 含有一个 since（自从） 引导的时态状语从句。主句通常用现在完成时， since 从
句通常使用一般过去时态，所以用一般过去时的被动语态，故选 B。
15 ．—Our school sports meeting last week. And we won the first prize.
—Sounds great. Congratulations!
A ．happened B ．took place C ．was happened D ．was taken place
【答案】B
【详解】句意：——我们学校的运动会上周举行了。我们赢得了一等奖。—— 听起来不错。
祝贺！
考查动词辨析和语态。 happened（偶然地）发生；出现； took place （有计划地）发生。两
者都没有被动形式。运动会应该是有计划地发生，故选 B。

【详解】
16．句意：如果把太阳能和天然气结合起来使用， 这将是一个很好的方法， 可以节省很多钱，
也更清洁。
taken 拿； used 使用； made 制作； cut 切。根据“If it is...by combining solar and gas power”可
知，把太阳能和天然气结合起来使用，故选 B。
17．句意：如果把太阳能和天然气结合起来使用， 这将是一个很好的方法， 可以节省很多钱，
也更清洁。
richer 更富有的； dirtier 更脏的； cleaner 更干净的； bigger 更大的。根据常识可知，风能、
太阳能和天然气都是清洁能源， 所以如果将它们结合起来使用将会使我们的生存环境更加干
净。故选 C。
18 ．句意：它不仅成本低，而且是一种清洁的能源，只要有风就可以储存。
costs 花费钱，主语是物；pays 付款，主语是人；spends 花费，主语是人；takes 花费，主语
是物。 it 在句中指代 a wind generator，当物作主语时，表示“花费钱”要用 cost 。故选 A。
19 ．句意：它不仅成本低，而且是一种清洁的能源，只要有风就可以储存。
cloud 云； snow 雪； rain 雨； wind 风。根据常识可知，风力发电的前提是有风。故选 D。
20 ．句意：根据正确的指导方针，你可以很容易地在家里制作风力发电机。
about 关于； of…… 的； with 和； on 在……上。根据“Wind generators can be easily made at home...the right guidelines”可知，在家使用风力发电需要有正确指导，介词 with 表示“带有”
符合语境。故选 C。
21 ．句意：但问题是我们没有足够多的有风的日子来生产一整天的所有能源。
any 任何； all 所有的； none 没有； few 几乎没有。根据“But the problem is that we don’t have enough windy days to produce...of the energy for a whole day.”可知，不够一整天的所有能源，
故选 B。
22 ．句意：这就是为什么用于野营的风力发电机很好，但对普通家庭来说远远不够的原因。 how 如何；when 何时；where 哪里；why 为什么。根据“This is...the wind power generator used for camping is fine, but not nearly enough for the average household.”可知，风力发电产生的能
源有限是它适用于野营但不适用于家用的原因，故选 D。
23 ．句意：美国有许多农场使用风力发电机。
farms 农场；schools 学校；factories 工厂；families 家庭。根据“The farmers...”可知，是农场，
故选 A。
24 ．句意：农民们把像螺旋桨一样的机器安装在杆子上，然后在很远的地方建造，因为它们
可能太吵了。
expensive 昂贵的；large 大的；noisy 吵闹的；terrible 糟糕的。根据常识可知，人们将它们建
在很远的地方是因为风力发电会产生很大的噪声。故选 C。
25 ．句意：许多当地能源公司已经限制使用风力发电机来提供额外电力。
usage 使用；electricity 电；money 钱；food 食物。风力发电是发电方式的补充，故此处表示
额外的电能。故选 B。
