四、选择合适的词组并用其正确形式填空。
separate into different groups depend on
run out make much difference to
1. Our food in a week.
2. The rain this match yesterday, and all the players performed pretty well.
3. The waste should before being thrown into the bin.
4. I don't want too much my parents.

1. will run out；2. didn't make much difference to；3. be separated into different groups；4. to depend；on

1. 句意：我们的食物一周后会用完。run out意为“用完，耗尽”，时间状语in a week表将来，用一般将来时，故填will run out。2. 句意：昨天的雨对这场比赛没太大影响，所有球员表现都很好。make much difference to意为“对……有太大影响”，由yesterday可知用一般过去时，结合语境表否定，故填didn't make much difference to。3. 句意：废物应该在扔进垃圾桶前被分成不同组。separate into different groups意为“分成不同组”，主语waste是动作承受者，用被动语态，情态动词should后接be+过去分词，故填be separated into different groups。4. 句意：我不想太依赖我的父母。depend on意为“依赖，依靠”，want to do sth.是固定搭配，故第四空填to depend，第五空填on。

五、根据所给汉语提示完成句子。
1. It （为……提供基础教育）children in poor areas.
2. （现代医药正迅猛发展）and now most eye problems and diseases can （被治疗或治愈）.
3. 污染环境是不明智的。
It is to .
4. 空气污染对很多动物有害。
Air is many animals.

1. provides basic education for；2. Modern medicine is developing rapidly；be treated or cured；3. unwise；pollute the environment；4. air pollution；harmful to

1. 主语It为第三人称单数，结合语境用一般现在时，“为……提供基础教育”的固定搭配是provide basic education for，故填provides basic education for；2. 第一空“现代医药正迅猛发展”用现在进行时，Modern medicine作主语，表达为Modern medicine is developing rapidly；第二空“被治疗或治愈”是被动语态，情态动词can后接be+过去分词，故填be treated or cured；3. “不明智的”对应形容词unwise，“污染环境”是pollute the environment，符合固定句型It is + adj. + to do sth.；4. “空气污染”是air pollution，“对……有害”是固定搭配be harmful to，故分别填air pollution和harmful to。
