一、根据汉语提示填写单词。

4. (塑料的) bags are bad for the environment, so we should use cloth bags more.
5. I think using (公共的) chopsticks is necessary when we eat with others.

1. project
2. possible
3. pool
4. Plastic
5. public

1. 此处汉语提示为“项目”，定冠词the后接名词，结合本专题为字母P相关词汇的要求，project符合语境和语法。
2. 此处考查固定搭配as much as possible，意为“尽可能多地”，汉语提示“可能”对应的单词possible符合搭配要求。
3. 此处汉语提示为“游泳池”，结合字母P的词汇要求，pool可表示游泳池，符合“在泳池里游泳”的语境。
4. 此处汉语提示为“塑料的”，修饰名词bags，位于句首首字母需要大写，Plastic是形容词，符合语义和语法。
5. 此处汉语提示为“公共的”，修饰名词chopsticks，形容词public符合句意要求。

二、用括号内所给单词的正确形式填空。
1. We can buy a lot of things at very good (price) on the Internet.
2. They are (plan) to climb the mountain this weekend.
3. It's important for us (protect) the environment.
4. The earth is one of the (planet) that move around the sun.
5. The (policeman) arrived soon and saved the little girl in the end.

1. prices
2. planning
3. to protect
4. planets
5. policemen

1. 考查名词复数，固定搭配at good prices意为“以优惠的价格”，句中提到购买很多商品，对应不同的售价，因此可数名词price要变为复数形式prices。
2. 考查现在进行时的谓语结构，现在进行时的构成为“be动词+动词现在分词”，plan的现在分词需要双写末尾辅音字母n再加ing，即planning。
3. 考查固定句型It's + 形容词 + for sb. to do sth.，该句型表示“对某人来说做某事是……的”，因此此处要填入动词不定式结构to protect。
4. 考查固定结构one of + the + 可数名词复数，意为“……之一”，说明地球是围绕太阳运转的众多行星里的一个，因此planet要变为复数形式planets。
5. 考查名词复数，句中没有不定冠词限定单数名词，结合救援的语境，此处表示多名出警的警察，policeman的不规则复数形式为policemen。

3. 根据答句"从父母那里得到30元"的提示，pocket money（零花钱）符合问句"每周得到多少零花钱"的语境。
