① 解析 讲述的是过去发生的事，用一般过去时。

② 解析 on/upon doing sth一做某事，就……；或者用现在分词作状语表示伴随。

③ 解析 flower为可数名词，由前面的trees可知此处应该用复数形式。 ④ 解析 句意：是在那个时候我们发现他的照相机丢了。此处是强调句式。 ⑤ 解析 句意：他非常担忧并翻遍了他的背包。上下文是并列关系。

⑥ 解析 strike使想起；使突然想到，是及物动词，后面直接跟宾语，不需要to；或者将struck改成occurred，occur to sb that...某人突然想起……，为固定搭配。

⑦ 解析 get in touch with sb与某人取得联系。
