考点-3.do强调谓语动词 和now that从句
【教材原句】...walking does need a bit of practice now that gravity has changed. ……既然重力改变了，行走的确需要一些练习 【句法分析】
(1) 句中 does need是一种强调句式。
do (does, did)常用来强调谓语动词的语气,译为“真的”“的确”“确实” “千万，务必”等。
He did helped me .他的确帮助过我。
Tom said he would come and that he did come.汤姆说他要来，他果真来了。 Do be careful next time. 下次千万要小心
(2) now that 在句中引导原因状语从句，相当于 since，意为“既然，由于”。
Now that you have finished your work, you‘d better have a rest. 既然工作已经做完了，你最好休息一下。 辨析：now that/because/since/as/for
now that 说明已经成为事实的原因，常译为“既然”。
because 语气最强，回答的是用 why提问的问句，表示直接的或为人所不知的原因。 since与 as语气较 because 弱，表示显而易见或已为人所知的原因。since 侧重主句，as主从并重，语气比 since 弱。
for是连词，用来补充说明理由或提供一种解释，不一定是真正的原因，不能放在主句前面。 例句：
—Why did you do this? 你为什么这么做？
—Because it is good for you. 因为这对你有好处。 Since you have known it, I won‘t repeat it. 既然你已经知道了，我就不重复了。
Wear strong shoes as we shall do a lot of walking. 穿上结实的鞋子，因为我们要走不少路。 It rained last night, for the ground is wet. 昨晚下雨了，因为地面是湿的。 【考点聚焦】考查强调和原因状语从句 【即时巩固】
