Language Points:
1.. I will never try to catch the falling dinosaur. 我不会尽力接住一个正在落下来的恐龙了。
【用法】句中的falling 是现在分词作定语，意思是“正落下的”，修饰后面的名词dinosaur。过去分词也有这种用法。
【举例】①Don’t wake up the sleeping boy. 不要叫醒那个熟睡的孩子。②The broken computer hasn’t been fixed yet. 那台坏电脑还没修好呢。
【拓展】现在分词或过去分词短语作定语时则应该放在它们所修饰的名词之后。
【举例】①Do you know the girl singing in the room 你认识正在房间里唱歌的那个女孩吗？②The table covered with paper is red. 用纸盖着的桌子是红色的。
2. I told her I would be careful. 我告诉她我会小心的。
【用法】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。
【举例】①The children said they wouldn’t play football in the street. 孩子们说不会在街上踢足球了。②He told me he would not go with us if it rained.他告诉我如果天下雨的话，他就不和我一起去了。
