課文重點分析

1. He sat and watched the butterfly for several hours as it struggled to force its body through that little hole. （見第2行） as在此句中是連接詞的用法，意思是「當……的時候」，可用while來代替。 例：He dropped the dish as he stood up. 他起身時把盤子掉到地上了。 As he was riding a bicycle in the park, he hit a stone and fell off. 他在公園騎腳踏車時，撞上石頭跌倒了。


as當連接詞時，亦可表示「因為」或是「依照」。
例：He couldn’t go to the movies with his friends, as he had no money left.
        他無法跟朋友去看電影，因為他身上沒錢了。
        Do your homework as your teacher told you.
        照著老師交代的方式去做功課。

2. Then it seemed to stop making any progress. （見第4行） stop 後接不定詞與動名詞意思不同。後接動名詞表示停止以下動作；後接不定詞表示開始以下動作。

文法／句型
stop + V-ing
stop + to V

Please stop making noise. I need to get some sleep.
請不要再弄出聲音來，我需要睡覺。
After walking a long distance, he stopped to take a rest.
走了很長一段距離之後，他停下來休息。

【補充】 stop + 受詞 + from + 動名詞 「阻止……去做某事」。
例：The policeman stopped us from driving into the small alley.
那位警察不讓我們開車進入小巷弄裡。

3. It appeared as if it could not go any further. （見第5行）
as if 是一種假設用法，等於as though。若是假設現在的情況，時態用過去式；若是假設過去的情況，時態用過去完成式。

文法／句型
as if + 子句
He acts as if he were a movie star.
他的行動舉止好像是個電影明星。
It sounded as if she had been very ill.
聽起來好像她那時病得很嚴重似的。


5. In fact, the butterfly spent the rest of its life crawling around with its swollen body and shriveled wings. （見第19行） 句中用到spend + time + V-ing

文法／句型
spend + time/money + V-ing

I spent three hours finishing my homework last night.
我昨天晚上花了三個小時做完功課。
My father spent NT$ 800,000 buying a new car.
我父親花了八十萬台幣買了一部新車。

另外，若要表示花時間∕金錢在某事物上，則要用 spend + time/money + on 的句型。

例1：The government should spend more money on education. 　　
         政府應該要在教育上多投入一些經費。
例2：Dr. Jones spent nearly fifteen years on this research.
　　 瓊斯博士花了將近十五年的時間在做這個研究。

6. Sometimes struggles are exactly what we need in our life. （見第27行）
由what所引導的名詞子句what we need in our life是主詞struggles的補語。

7. If God allowed us to go through our life without any obstacles, we would be crippled and would never be able to fly. （見第28行） 此句為假設用法，表示與現在情況不符的假設，時態用過去式；表示與過去情況不符的假設，時態用過去完成式。

文法／句型
If + S + p.t./were ..., S + would + V ....

If I knew the answer to the question, I would tell you.
如果我知道問題的答案，我會告訴你。
事實：I do not know the answer to the question, so I am not able to tell you.
