2019屆高考英語單項選擇題精講

a. attended b. attending c. to attend d. have attended

25. i can _____ some noise while i’m studying, but i can’t stand very loud noise.
a. put up with b. get rid of c. have effects on d. keep away from
解析：從后面的stand可以推斷，這里用put up with 表示忍受
26. before leaving home, make sure to turn off the electricity, lock the door, ______ the windows open.
a. and not to leave b. instead of leaving c. rather than leave d. and not leave

28. space exploration has been made ______ with the development of modern science and technology.
a. it possible b. it was possible c. that possible d. possible
解析:該句測試是make sb./ sth.+adj. 結(jié)構(gòu)，如果用a項，后應(yīng)用to do sth.，因為it是形式賓語，代替不定式。
with the development of modern science and technology, man has made space exploration possible.
29. we want such materials ________ can bear high temperature and pressure.
a. that b. as c. what d. which
解析such materials as 引導(dǎo)的是定語從句,as 在從句中作主語；而such materials that 引導(dǎo)的是結(jié)果狀語從句，that 在從句中不充當(dāng)成分。
30. hardly ___________the door when he rushed into the office out of breath.
a.i opened b. did i open c.i had opened d. had i opened
解析hardly 以及含有否定意義的副詞放在句首，句子用倒裝結(jié)構(gòu)。
hardly…when/ no sooner…than 用法相同。
