Explain the language points:I will never try to catch a falling dinosaur. catch a falling dinosaur意为“接住一只往下掉的恐龙”，指去做超过自身能力的事情。falling是fall的-ing形式，在句中作dinosaur的定语。不及物动词的-ing形式可表示正在进行或尚未结束的动作，而过去分词可以表示完成了的动作。You advised him to use a ladder, but he didnt listen. advise为及物动词，意为“劝告，建议”。advise sb. to do sth.意为“建议某人做某事”，advise sb. not to do sth.相当于advise sb. against sth./doing sth.意为“劝告某人不要做某事”。advise的名词形式为advice，是不可数名词。I told her I would be careful. 这是带有宾语从句的复合句，主句为一般过去时，从句用的是过去将来时。would be careful在这里表示“过去将要做某事”。“Dont climb too high,” she warned. high为副词，指具体的“高”。副词highly通常指抽象的“高，高度”。warn为及物动词，意为“警告”，其名词形式为warning, warn sb.(not)to do sth.意为“提醒/警告某人(不要)做某事”。She watched me climb higher and higher. watch sb. do sth.意为“看见某人做某事”，watch sb. doing sth.意为“看见某人正在做某事”。(1)watch, see, notice, hear等感官动词的宾语跟省略to的动词不定式作宾语补足语。(2)higher and higher意为“越来越高”。“比较级+比较级”表示“越来越”，若是多音节形容词，其结构为“more and more+多音节形容词”。6.It took me three months to recover. “It takes/took sb. some time to do sth.”意为“做某事花费某人多长时间”。By the way, do you like the gift I sent you? by the way意为“顺便问一下，顺便说一下”，常用作插入语。take care意为“走好，保重”，是告别用语。take care还意为“当心，小心”，相当于be careful。Step 3.
