三、【感叹句】感叹句可以帮助我们抒发情感。请将画线部分的句子变成感叹句。
Liu Tao and Mike are talking about protecting the environment.
Liu Tao: Look at the river near our school. 1. The river is very clean now.
Mike: Yes! People stopped throwing rubbish into it.
Liu Tao: And look at the trees. 2. The trees are so tall.
Mike: The workers water them every day.
Liu Tao: 3. That's a good way to keep the air fresh.
Mike: You're right. We should also use reusable bags.
Liu Tao: 4. You are very clever!
1. What ! 2. How !
3. What ! 4. How !

1. a clean river (it is) now
2. tall the trees are
3. a good way (it is) to keep the air fresh
4. clever you are

【分析】
要完成感叹句转换，需先明确英语感叹句的两种核心结构：①What引导的感叹句，修饰名词，结构为“What + (a/an) + 形容词 + 名词 + 主语+谓语！”（可数名词单数加a/an，复数/不可数名词不加）；②How引导的感叹句，修饰形容词/副词，结构为“How + 形容词/副词 + 主语+谓语！”。解题时需先找出原句的核心修饰成分（名词/形容词），再对应结构转换即可。
【解析】
1. 原句核心修饰成分是可数名词单数“river”，用What引导感叹句，对应结构转换为：What a clean river (it is) now！
2. 原句核心修饰成分是形容词“tall”，用How引导感叹句，对应结构转换为：How tall the trees are！
3. 原句核心修饰成分是可数名词单数“way”，用What引导感叹句，对应结构转换为：What a good way (it is) to keep the air fresh！
4. 原句核心修饰成分是形容词“clever”，用How引导感叹句，对应结构转换为：How clever you are！
【答案】
1. a clean river (it is) now
2. tall the trees are
3. a good way (it is) to keep the air fresh
4. clever you are

四、【一般过去时与一般将来时】从方框中选择合适的单词，用其适当形式补全短文。
see visit be buy share go live pick
Last Sunday, my family and I 1. to Xuanwu Lake Park. We 2. some plastic rubbish on the ground. We 3. so sad to see the dirty ground, so we 4. up the waste together.
Mum 5. her ideas with us, “I promise that we 6. the city recycling centre. We 7. some reusable shopping bags. We won't use plastic bags or bottles from then on. We 8. a much greener life!”

1. went 2. saw 3. were 4. picked
5. shared 6. will visit 7. will buy
8. will live

【分析】这道题要求用方框内单词的适当形式补全短文，需结合时间状语判断时态：短文前半部分提到“Last Sunday”（上周日，过去时间），对应1-5空需用一般过去时；后半部分是妈妈对未来的计划，对应6-8空需用一般将来时（will+动词原形）。再结合语境匹配方框内的单词，转换为正确形式即可。
【解析】1. 由时间状语Last Sunday可知，此处用go的过去式went，构成“go to+地点”结构；2. 语境为“看到地上的塑料垃圾”，用see的过去式saw；3. 主语是we，时态为一般过去时，be动词用were，构成“be sad”（难过）；4. pick up是固定短语“捡起”，此处用pick的过去式picked；5. 语境为“妈妈和我们分享想法”，用share的过去式shared；6. 此处是未来计划，用一般将来时，即will+visit；7. 未来动作，用一般将来时，即will+buy；8. 未来动作，用一般将来时，即will+live。
【答案】1. went 2. saw 3. were 4. picked 5. shared 6. will visit 7. will buy 8. will live
【知识点】一般过去时、一般将来时、动词适当形式填空
【点评】本题聚焦英语时态的基础应用，通过时间状语明确时态类型，再结合语境匹配单词并转换形式，是初中英语时态部分的典型基础题，有助于巩固一般过去时和一般将来时的用法。
