第1句 從句最好用現(xiàn)在完成時,強調(diào)“通過了”（結(jié)果）
第3句 在周末 at或over the weekend 或 on weekends,一般不用in
第4句 用一般現(xiàn)在時比較好 find（不要過去時）,保持健康（應該是keep healthy,或keep fit）作主語,用動詞不定式或動名詞形式,本句改為：2種
從句：In the modern society more and more people find that to keep healthy is v isery important.
不用從句：用形式賓語
In the modern society more and more people find it very important to keep fit.
第5句 天氣變得,應該用形式主語it,不是the weather,越來越冷（colder是cold的比較級,不是more and more,cold是單音節(jié)詞）,而且兩個句子間要用連接詞
It is becoming colder and colder, and you'd better wear more clothes.
