4. People who work and live under conditions usually become deaf (聋子).
5. Don't worry! We'll make sure that the children come to no .

1. wildlife
2. topics
3. tons
4. noisy
5. harm

1. “野生动物”的英文为wildlife，为不可数名词，在此处符合题意。
2. 根据“age, weight or money”可知，这些都是比较私密的话题，结合首字母t，可想到“话题”这个单词，且为可数名词，故此处应填topics。
3. “吨”的英文为ton，是可数名词。hundreds of后接可数名词的复数形式，所以此处应填tons。
4. 根据“usually become deaf”可知，人们通常变聋，是因为他们工作或生活的环境噪声很大。结合首字母n，可想到“噪声”这个单词，且此处为形容词修饰名词，故应填noisy。
5. 根据“Don't worry!”可知，此处应是让对方放心，孩子们不会有危险。结合首字母h，可想到“危害”这个单词，且come to no harm为固定短语，意为“不受伤害”，所以此处应填harm。

二、用所给单词的适当形式填空
1. The (sand) island sank beneath the waves soon afterwards.
2. We became (trap) by the rising floodwater.
3. Fruit juices can be (harm) to children's teeth.
4. (sad), bamboo plants die after flowering.
5. This can prevent air from (flow) freely to the lungs.

1. sandy
2. trapped
3. harmful
4. Sadly
5. flowing

1. 此处需要一个形容词来修饰名词island，sand的形容词形式是sandy，表示“沙质的”。因此填sandy。
2. 根据句意和became的提示，这里表示“被困住”，trap的过去分词形式trapped可以表示这种状态。因此填trapped。
3. 在be动词后作表语，需要用形容词形式，harm的形容词是harmful，表示“有害的”。因此填harmful。
4. 此处需要用副词来修饰整个句子，表示“令人难过地”，sad的副词形式是sadly。因此填Sadly，注意首字母大写。
5. prevent...from...中的from是介词，后面接动词时要用动名词形式，flow的动名词是flowing。因此填flowing。

1. There is , which makes deserts dry.
2. give animals water.
3. Some animals the leaves of plants.
4. The water in the leaves .
5. The flowers and fruit can provide .

1. little rain and too much sunlight
2. Many plants in deserts
3. feed on
4. keeps them healthy
5. energy for animals

1. 第一个句子需要表达“降雨稀少,阳光过于强烈”，根据语境，应使用“little rain”表示降雨少，“little”修饰不可数名词rain，表示否定意义“几乎没有”；“too much sunlight”表示阳光过于强烈，“too much”修饰不可数名词sunlight。
2. 第二个句子需要表达“沙漠中的许多植物”，使用“Many plants in deserts”即可，其中“in deserts”作为后置定语修饰“Many plants”。
3. 第三个句子需要表达“以…为食”，使用“feed on”短语。
4. 第四个句子需要表达“使他们保持健康”，使用“keep them healthy”结构，“keep”后接宾格“them”再接形容词“healthy”表示状态。
5. 第五个句子需要表达“为动物提供能量”，使用“provide energy for animals”结构，“provide sth. for sb.”是固定搭配。

四、微写作 Introduce one of the ecosystems with and, but, or, and so. (At least 5 sentences.)

A forest is a wonderful ecosystem, and it is home to many plants and animals. Trees in the forest are tall and strong, but some small plants grow under them too. You can see birds singing in the trees, or squirrels running quickly on the branches. The forest provides clean air and water for animals, and so they can live happily there. People should protect the forest, for it is very important for our Earth.
