 Part A    词汇精讲

1. starve　vi. / vt.　挨饿；饿死；使缺乏　★

An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died.

· starve to death　饿死

· be starving　饿极了（口语）

· starve sb of sth　使某人缺乏……

· starvation　n. 饥饿；饿死（不可数）

注意：“饿死”说 starve to death，不说 starve to die；名词是 starvation，die of starvation 对，die of starve 错。另外 starve of 是“使缺乏”，starve for 才是“渴望”。

即练　(1) The lake was starved ______ oxygen by the algae.

(2) 山里的孩子渴望知识。（starve for）

2. impact　n. / vt.　影响；冲击

This alarming case showed how the increase in temperature had an impact on Earth’s ecology.

The heat is released back into space at longer wavelengths.

· release sth into　把……排放到……

· the release of CO2　二氧化碳的排放

· release sb from　把某人从……中放出来

· a news release　新闻稿

注意：wavelength 是一个词，写成 wave lengths 就错了；release 及物，热“被释放”要用 is released，不能说 The heat releases into space。

即练　(1) The report ______ (release) yesterday lists the ten most polluted rivers.

(2) 工厂不得把废水直接排入长江。（release ... into）

4. comprehensive　adj.　全面的；详尽的　★

There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide…

· a comprehensive survey　一项全面的调查

· comprehensive evidence　有力且全面的证据

· comprehend　vt. 理解（comprehension n. 理解力）

· a reading comprehension　阅读理解

注意：comprehensive 是“全面的”，comprehensible 是“能理解的”，两个词只差几个字母，考题常拿来对换。

即练　(1) The police conducted a ______ (comprehend) review of the case.

(2) 这份报告对东湖的水质做了一次全面调查。（a comprehensive survey）

5. frequently　adv.　频繁地；经常　★

In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses.

· frequent　adj. 频繁的

· frequency　n. 频率；频繁

· a high / low frequency　高／低频

· occur / happen frequently　经常发生

注意：frequently 是副词，修饰动词时放在实义动词前、be 动词后；“经常的新闻”要用 frequent，不能用 frequently。

即练　(1) Such storms now occur more ______ (frequent) than they did twenty years ago.

6. emission　n.　排放；排放物　★

Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate.

· carbon emissions　碳排放

· cut / reduce emissions　减少排放

· emit　vt. 排放（emitted, emitting）

· greenhouse gas emissions　温室气体排放

注意：emission 可数，泛指排放时常作 emissions；动词是 emit，过去式和 -ing 都要双写 t：emitted、emitting。

即练　(1) Cars ______ (emit) a large amount of carbon dioxide every day.

(2) 新的规定要求工厂减少排放。（cut emissions）

7. harmonious　adj.　和谐的；协调的

In response to this environmental issue, China is implementing significant policies and measures to address climate change, aiming to restrict coal consumption, promote a harmonious relationship between man and nature…

· a harmonious relationship　和谐的关系

· live in harmony with　与……和谐相处（用名词 harmony）

· in harmony　和谐地；协调地

· harmony　n. 和谐；融洽

注意：“与自然和谐相处”是 live in harmony with nature，介词 in 后面用名词；写成 live in harmonious with 就错了。

即练　(1) The only way for us to survive is to live in ______ (harmonious) with nature.

(2) 这座城市在发展中保持了人与自然的和谐。（a harmonious relationship）

8. submit　vt. / vi.　提交；呈递；屈服

· submission　n. 提交；屈服
