① 解析 be worried about＝worry about，意为“担心”。 ② 解析 fall off跌落，从……摔下，其后直接跟宾语。 ③ 解析 特指上文提到的自行车。
④ 解析 此处是with复合结构，my mother与carry是主谓关系，故用现在分词形式表示主动。
⑤ 解析 副词作状语修饰动词say。
⑥ 解析 most修饰可数名词复数或不可数名词，family为可数名词，故用复数形式。 ⑦ 解析 此处的意思是：父母想要为他们的孩子做所有事情。与下文语态保持一致。 ⑧ 解析 love为不可数名词，用too much修饰。
⑨ 解析 prevent…from doing…阻止……做……，为固定搭配。 ⑩ 解析 此处what引导宾语从句，并在从句中作do的宾语。
