【解析】

試題分析：句意：如果明天不下雨，我們將去公園。本題考查If引導(dǎo)的條件狀語從句，主句用一般將來時，從句用一般現(xiàn)在時。結(jié)合句意，故選D

考點：考查動詞時態(tài)。

考點分析： 考點1：狀語從句 狀語從句：在句子中起狀語作用的從句稱為狀語從句。有的狀語從句可以在主句前（其后常用逗號與主句隔開），有的狀語從句可以在主句后（其前不用逗號與主句隔開），有的既可以在主句前又可以在主句后。狀語從句通常由一個連詞或由一個起連詞作用的詞組引導(dǎo)。狀語從句可以表示時間、地點、原因、目的、結(jié)果、條件、方式、讓步和比較9種意義。中考主要考查時間狀語從句和條件狀語從句中的時態(tài)問題。也就是我們所說的“主將從現(xiàn)”，主要以單選形式為主，占1-2分。
（一）時間狀語從句：由when, while, before, after, since, as soon as, till / until引導(dǎo)的從句
1）when與while
  1)I’ll tell her the good news _____he comes back.
  2)Aunt Wang came in while we were watching TV
3)since:自從……以來(since從句常用一般過去時)
注意主句通常用現(xiàn)在完成時，但當(dāng)主句表示一種狀態(tài)，用一般現(xiàn)在時
  1)He has lived there since he came to China
  2)It is two years since her mother died.
（二）條件狀語從句：由if (如果)引導(dǎo)的從句
I will go to the park if it ________ (not rain) tomorrow.
注意：條件狀語從句與以下句型的轉(zhuǎn)換
1）祈使句，and (then , or)+簡單句
 = If you … , you …
eg.1)Use your head, then you’ll find a way.
 =If you use your head, you’ll find a way
  2)Hurry up, or you’ll be late.
 =If you don’t hurry, you’ll be late.
2)without與條件句的轉(zhuǎn)化
eg. Man can’t live without water.
 =Man can’t live if there is no water.
注意以上兩種狀語從句的時態(tài)
主句 時間、條件句
1）一般將來時 2）祈使句 3）情態(tài)動詞原形 一般現(xiàn)在時
一般過去時 一般過去時
但since從句例外，應(yīng)與現(xiàn)在完成時連用。
eg.1)I’ll call you as soon as he ______ (come) back.
  2)He won’t go to bed until he _________ (finish) his homework.
 3)I’ll help you if I _____ (be) free tomorrow
 4)I ___________ (live) here since I came to China.
（三）原因狀語從句：由because, since , for , as引導(dǎo)的從句
eg. He didn’t go to school because he was ill.
注意：1)對because引導(dǎo)的從句提問用why
      2)因為(because), 所以(so)不能連用
eg. Because he was (A) ill, so (B) he didn’t (C) go to school (D) yesterday.        ________
（四）結(jié)果狀語從句：由so… that引導(dǎo)的從句（so后接形、副原級）
eg. He ran (A) so faster (B) that I couldn’t catch up with (C) him.           ________
注意：1) “so… that +否定句”與“too… to”的替換
eg.1)He is so young that he can’t go to school.
= He is too young to go to school(主、從句主語相同)
2)He ran so fast that we couldn’t catch up with him.
= He ran too fast for us to catch up with. (主、從句主語不同)
3)The box is so heavy that I can’t carry it
= The box is too heavy for me to carry.(注意carry后省去賓語it)
2）“so… that +從句”與“enough to”的替換
eg.1)He’s so strong that he can carry the box.
= He’s strong enough to carry the box.
  2)The question is so easy that I can answer it
=The question is easy enough for me to answer
