一、country; nation; state; land
1.
2. He was forced to leave his native ______.
3. In our country, mothers and children are protected by the ______.
4. Trade between ______ is better than war.
【答案】1. country 2. land 3. state 4. nations
【点拨】这四个词都有“国家”的意思，但使用时侧重点不同。country是不含任何感情色彩或引申意义的普通用词，意思是“国家”或“乡下；农村”。指“国家”时，侧重疆土。 nation强调国家的民族性。 state是“国家”或“州”。指“国家”时，侧重政权。 land强调国家的国土、疆土。
二、whatever; no matter what
1. _______ he says, it makes no difference to me.
2. He was to do _______ we told him to do.
3. ______ his post is, he always works with a revolutionary drive.
【答案】1. Whatever/No matter what 2. whatever 3. Whatever/No matter what
【点拨】两者均表示“无论什么”，whatever能引导让步状语从句、主语从句、宾语从句，当引导让步状语从句时可与 no matter what互换。而 no matter what一般只能引导让步状语从句。
三、celebrate; congratulate
1. We ______ the New Year’s Day every year.
2. Let’s ______ him on his success.
3. They’re ______ the victory.
4. We ______ Christmas with a tree and presents.
【答案】1. celebrate 2. congratulate 3. celebrating 4. celebrated
【点拨】celebrate 作“庆祝；祝贺”解，是及物动词，其宾语只接表示事物的词 (如：节日、生日、胜利、成功或事件等)而不接人，也不接that 从句。congratulate作“庆贺”解时，其后只能接被庆贺的人作宾语，句型是：congratulate sb. (on sth.)。 注意: 在表示“祝贺”时，口语中往往只说Congratulations。例如：— You know what? I’ve just got a pass in the examination. — Congratulations!
四、think of; think about; think over
1. Just______ the cost.
2. What did you ______ the report?
3. I’d better ______ what he said.
4. I can’t ______ his name right now.
5. He always ______ other people first.
【答案】 1. think about 2. think of 3. think over 4. think of 5. thinks of
【点拨】think of表示“想到；想起”，也可指“对某事物有……看法”。think about表示“考虑；想一想”。 think over 的意思是“仔细考虑”或“重新考虑”。
