1. 主语weather是不可数名词，句中时间标志now表示当前状态，be动词用is。
2. 此处修饰动词running，需要用副词形式，形容词slow的副词变形为slowly。
3. 此处用动词不定式作目的状语，表达司机打开雾灯的目的是看清路况，填to see。
4. 句首Look!提示动作正在发生，使用现在进行时，主语Some people是复数，be动词搭配are，walk的现在分词为walking，故填are walking。
5. umbrella是发音以元音音素开头的可数名词单数，此处表示“一把雨伞”，用不定冠词an。
6. 固定搭配do morning exercises意为“做早操”，是七年级核心常用短语，填exercises。
7. 此处表达“他们选择像太极这类的轻柔运动”，介词like意为“像”，符合语境。
8. 此处修饰名词scenery，需要用形容词作定语，名词fog的形容词变形为foggy，意为“有雾的”。
9. 固定搭配be interested in意为“对……感兴趣”，形容词interested用于描述人的主观感受，填interested。
10. 句中时间标志soon表示动作发生在将来，使用一般将来时，结构为will+动词原形，故填will have。
