二.重點句型突破
1. it/this /that is the first/second….time that-clause . 這/那是第一次/二次…..做某事，此時that 從句用現在完成時，但如果主句中用was, 則that 從句用過去完成時。
1） --have you ever been there before?
---this is the first time i ________(be)to the summer palace.
2) i must be going. it’s time i ________(pick) up my daughter from school.
3)by the time you come back, we ___________(finish) our homework.
4)it is time for us _________(go ) to bed.
2. with 的復合結構
with +賓語+賓補（形容詞/副詞/介詞短語/現在分詞/過去分詞/不定式），在句中常做狀語。判斷賓補時注意：v-ing 表主動、進行；v-ed 分詞表被動且完成；to do 表將來動作。
1）she was thinking for a while with her eyes ________(close).
2）he often sleeps with his windows___________(open).
3）she ran and ran with beads of sweat ________(run)down her face.
4）with a lot of homework _________(do),tom couldn’t go out to play with them.
3. 強調句型基本結構 it is/was+被強調部分+that/who/whom+其他成分
【基礎過關】 it is/was+被強調部分+that/who/whom+其他成分
原句：i met li ming at the railway station yesterday.昨天我在車站碰見了李明。
強調主語：it was i that/who met li ming at the railway station yesterday.
強調賓語：it was li ming that/whom i met at the railway station yesterday.
強調地點狀語：it was at the railway station that i met li ming yesterday.
強調時間狀語：it was yesterday that i met li ming at the railway station.
【拓展延伸】注意：
(1)在這種強調句式中，一般用that引出句子的其他成分。如果被強調的部分是表示人的意義的名詞時，可以用who代替that引出句子的其他成分；如果被強調的部分是表示事物意義的名詞時，用that引出句子的其他部分。但是，無論被強調的部分是地點狀語還是時間狀語，都不可以用where或者when.
如：
it is that man who/that teaches our english.
(2)原句的謂語動詞時態是一般過去時、過去進行時、和過去完成時，用it was----,其他時態用it is-----.
