Question

有几个英语问题小弟不明白 请各位指点迷经

As the man tried to swing the speedboat round, the steering wheel came away in his hands. 为什么这里有round这个词 swing是转向的意思已经足够了啊 round完全可以去掉啊
He waved desperately to his companion, who had been water skiing last fifteen minutes 这里的water如何解释呢 后边定于的宾语从句主语是谁呢 是been吗 这个句子没法写成现在完成进行时吧

before long 是不久的意思我实在是记不住我改怎么理解呢

Answer 1

1.As the man tried to swing the speedboat round, the steering wheel came away in his hands

看懂意思。当那个男人试图让快艇转弯时，方向盘脱手了。
swing是偏向“旋转”那种的，你加上round更好理解为转弯(或者很大幅度的转弯)，但我要说你不加round也没有多大问题，这个句子大家都能理解。

2. He waved desperately to his companion, who had been water skiing last fifteen minutes 这句话里面water-skiing是一个词，是用滑水板在水面上滑行的活动；主语是companion 因为前面有提到他向朋友招手

3.我觉得你大概是before long和long before混了？
那你就这么想呗，long before=long time ago 顺序一样
before long开头是b，和“不”发音相近。。。这种单词记忆个人对个人，实在没法提供有效帮助……

祝学习进步，满意请采纳，谢谢。
