1. planet
2. through
3. deep

1. 根据句意“我们的地球是一颗绕着太阳运转的蓝色行星”，结合首字母提示p，可知此处填名词planet，意为行星。
2. 根据句意“清江流经恩施”，结合首字母提示t，固定搭配run through表示“流经、穿过”，可知此处填through。
3. 根据句意“我们可以用很多方式表达对父母深深的爱”，结合首字母提示d，此处用形容词deep修饰名词love，意为深深的，故填deep。
4. 根据给出的音标[ˌaʊt'saɪd]，对应的单词是outside，意为在……外面，符合句子语境。
5. 此处是while引导的时间状语从句的省略结构，省略了主语we和be动词are，结合“刷牙”的常用短语brush one's teeth和首字母提示b，可知要填brush的现在分词形式brushing。

第二节 阅读短文,用括号里所给单词的正确形式填空。
Water is important, but many 6 (place) don't have enough water. That's why we must use it 7 (wise).
First, let me tell a story. There are some families 8 (live) in the desert. They have very little water. So they never 9 (waste) it on things like flowers or grass. Each person can only shower for a few minutes 10 (one) a week. During the shower, they have to collect the water for 11 (late) reuse such as washing clothes or cleaning the house. Rain almost never 12 (fall), so most families have to dig wells 13 (find) water. It's very difficult and expensive.
After 14 (know) about their life, I think we should help save water in small
ways. For example, at home, we can make a big 15 (different). Turn off the tap when we don't need 16 (use) water. Outside, water 17 (plant) early in the morning when it's cool. And don't throw away 18 (drink) water bottles when there 19 (be) still water in them.
Remember, it's not hard to save water. Just think before using 20 (it). If we all try our best, we'll have enough water for everyone.

我们逐个分析每个空的解题依据：
6. many后接可数名词复数，place是可数名词，直接变复数为places。
7. 此处修饰动词use，需要用副词形式，形容词wise的副词形式是wisely，意为“明智地”。
8. 固定结构there be + 名词 + doing sth 表示“有某人处于做某事的状态”，live的现在分词是living。
9. 主语是they，句子为一般现在时，频度副词never后接动词原形waste。
10. 固定搭配once a week 表示“一周一次”，基数词one变为once，意为“一次”。
11. 此处表示“后续的”再利用，late变为later，构成短语later reuse，意为“后续重复利用”。
12. 主语Rain是不可数名词，句子为一般现在时，谓语动词用第三人称单数形式，fall变为falls。
13. 此处用动词不定式作目的状语，表示挖井的目的是取水，填to find。
14. after是介词，介词后接动名词形式，know的动名词是knowing。
15. 固定短语make a big difference 意为“产生很大影响”，形容词different的名词形式是difference。
16. 固定搭配need to do sth 意为“需要做某事”，填to use。
17. 此处water是及物动词，意为“给……浇水”，后面接泛指的植物作宾语，要用复数形式plants。
18. 动名词作定语表示用途，drinking water bottles 意为“饮用水瓶”，填drinking。
19. there be句型中，后面的名词water是不可数名词，句子为一般现在时，be动词用is。
20. 介词using后接人称代词宾格，it的宾格形式还是it，直接填it。
