你好。不一定。如:
Now that everyone is(一般现在时) here, let's begin。
(表状态,用一般现在时)
Now that everyone has arrived(现在完成时),let's begin.
(表动作,用现在完成时)本回答被网友采纳

在SAT中必须用现在完成时, 官方解答:the adverb "now" indicates action begun in the past but continuing until the present (action described
correctly by the present perfect tense).
仅限SAT~

不一定,要根据句意来判断,now that是既然的意思
