18、處意為“也不”，是副詞。例如： Mary doesnt like singing. Neither do I. 瑪麗不喜歡唱歌，我也不喜歡。（我和Mary 有相同的情況，前句是否定句，下文用neither開頭，主謂倒裝）如果上文是肯定句，下文表示與上文有相同情況時，用“so+ be動詞/助動詞/情態動詞 + 主語”。例如：Mary likes singing. So do I. 瑪麗喜歡唱歌。我也喜歡。（我和Mary有相同情況，前句是肯定句，下文用so開頭，主謂倒裝）【拓展】 當表示對上文所講內容的贊同時，可以用“so + 主語 + be動詞/助動詞/情態動詞”或者“neither + 主語

19、+ be動詞/助動詞/情態動詞”來表示。前者用于肯定句，后者用于否定句。例如：Mary plays the piano well. So she does. 瑪麗鋼琴彈得很好。她確實彈得好。(表示對上文所講內容的贊同，前句是肯定句，下文用so開頭，主謂不倒裝)Mary doesnt play the piano well.

20、條件狀語從句。在以when，after，as soon as等引導的時間狀語從句以及以if，unless等引導的條件狀語從句中，如果主句是一般將來時，從句則用一般現在時表將來。例如： Ill tell her the good news when she comes back. 當她回來的時候，我將把這個好消息告訴她。 If it doesnt rain, he will come here on time. 如果不下雨，他會按時來這兒的。 常見的“主將從現”有以下三種情況： 1）條件狀語從句的主句是一般將來時，那么從句常常用一般現在時。例如： When I grow up, Ill be a
