2.pollution/p3'lun/n.污染;污染物;玷污
·易错点:易与动词pollute /p3'lut/混淆,词性和拼写差异易出错:易误写为pollusion(多写字
母s)。

water_(污染).(答案:pollution)
3.waste /weist/n.浪费;废弃物:垃圾V.浪费;滥用;白费
·易错点:作动词时易与wasteful(形容词,浪费的)混淆:作名词表示“废弃物”时,易误加
复数。
·精讲:作动词常用搭配waste time/money on sth.(在某事上浪费时间/金钱);作名词时,ub-
bish/waste均表示“垃圾”,waste更侧重“无用的废弃物”。
.(1)Don't waste too much time playing games.(v.)(2)We should sort the waste before throwing
it away.(n.)

5.conserve /kan's3v/v.保护:保存;节约
·易错点:易与preserve(保护,侧重“维持原状”)混淆:易误写为conservate(错误拼写,无
此词)。

“保护免受破坏”,如preserve ancient buildings(保护古建筑)。

容词或副词,如worldwide attention(全球关注)。
·例句:Global warming is a serious problem for all countries.
·真题链接:(重庆大学版高中必修第二册同步练习):The problem of_(全球的)warming has
attracted much attention..(答案:global)
9.carbon/'kab/n.碳;碳元素
·易错点:易误写为carbone(多写字母e):固定搭配carbon dioxide(二氧化碳)易漏写dioxide。
·精讲:carbon为不可数名词,常用搭配carbon footprint(碳足迹):carbon dioxide是专有名词,
不可拆分。
