一、词汇运用
A. 根据首字母或汉语提示,写出各单词的正确形式,每空一词。
1. What caused the accident remains (未知的). We need to do more research on it.
2. —Do you know how people eat?
—In most Western countries, people don't eat with (筷子). They use knives and forks.

4. Christopher Columbus was one of the first (欧洲人) to discover America.
5. The (发现) of the new type of energy is important to the development of the whole city.
6. —Have you seen his ? It can help warm hands in winter.
—Not interested. He always invents some useless things.

1. unknown 2. chopsticks 3. pride 4. Europeans 5. discovery 6. invention

1. "未知的"对应形容词"unknown"，remain后接形容词作表语。
2. "筷子"常用复数形式"chopsticks"，表示一类事物。
3. "骄傲"对应名词"pride"，"be full of pride"为固定搭配。
4. "欧洲人"是"European"，"one of+复数名词"，故用"Europeans"。
5. "发现"对应名词"discovery"，由定冠词"the"可知用名词形式。
6. 根据"invents some useless things"及首字母"i"，可知是"invention"（发明），由"his"和"it"可知用单数。

B. 从方框中选择恰当的单词,并用其适当形式填空,每个单词只能用一次。
Russia, test, save, far, record, invent, fight, serve
1. As we all know, Thomas Edison is famous as an .

1. inventor 2. was recording 3. tests 4. fighter 5. will save 6. Russians 7. serving 8. further

1. "invent" 发明，根据主语 Thomas Edison 及 "an" 可知用名词 "inventor"（发明家）。
2. "record" 记录，由 "While my teacher was making a speech" 可知用过去进行时 "was recording"。
3. "test" 考验，动名词短语作主语，谓语动词用第三人称单数 "tests"。
4. "fight" 斗争，"a fighter" 表示“一名战士”，符合句意。
5. "save" 节省，if 引导的条件状语从句用一般现在时，主句用一般将来时 "will save"。
6. "Russia" 俄罗斯，"Russians" 表示“俄罗斯人”，three quarters of 后接可数名词复数。
7. "serve" 服务，"devote...to doing sth." 致力于做某事，用 "serving"。
8. "far" 远的，"further" 表示“进一步的”，修饰名词 "help"。

() 1.Bernard Shaw was a great English playwright who died ______.
A.at his age of 94
B.at age of 94
C.in the age of 94
D.at the age of 94

D

“在……岁时”的正确表达为“at the age of+基数词”，是固定搭配。选项A多了“his”，选项B缺少定冠词“the”，选项C介词使用错误，应为“at”而非“in”。故正确答案为D。

() 2.—What do you think of the film Transformer?
—It's fantastic. The only pity is that I ______ the beginning of it.

A.missed
B.was missing
C.will miss
D.miss

A

根据对话内容，“The only pity is that I ______ the beginning of it.”表达的是对过去某个具体时间点（电影开始时）发生的事情的遗憾，即错过了电影的开头。这里描述的是一个已经发生的事实，所以应该用一般过去时。选项A“missed”是一般过去时，表示“错过了”；选项B“was missing”是过去进行时，表示过去某个时间正在进行的动作，不符合语境；选项C“will miss”是一般将来时，表示将来要发生的动作，不符合语境；选项D“miss”是一般现在时，表示通常性、规律性、习惯性、真理性的动作或状态，也不符合语境。因此，正确答案是A。

( ) 3.—Chinese astronauts can also walk in space now.
—Yes. They are the our nation.

A.proud of
B.pride of
C.pleased with
D.known for

B

根据句意“他们是我们国家的骄傲”，“the pride of...”表示“……的骄傲”，为固定搭配。A选项“proud of”需用“be proud of”结构；C选项“pleased with”表示“对……满意”；D选项“known for”表示“因……闻名”，均不符合句意。此处需要名词“pride”，故选B。

() 4.Marie Curie was a famous woman scientist and was famous for ______ radium.
A.inventing
B.discovering
C.invention
D.discovery

B

本题考查词义辨析。invent表示“发明”，指创造出世界上原本不存在的东西；discover表示“发现”，指找到本来就存在但之前不为人知的事物。居里夫人发现了镭，镭是本来就存在的元素，所以用discover，且for是介词，后面接动词的-ing形式，所以用discovering。A选项inventing是“发明”不符合语境；C选项invention是名词“发明”；D选项discovery是名词“发现”，均不符合语法要求。
