27、可，代詞作賓語要置于副詞之前。If you dont know the meaning of a word，look it up in a good dictionary.如果你不知道一個(gè)詞的意義，就去查一本好詞典。You can look up her telephone number in the book.你可以在電話簿里查找她的電話號(hào)碼。Will you look up a train for me in the timetable?你可不可以幫我在行車時(shí)刻表中查找一個(gè)列車車次?11.

29、句，又在從句中作exchanged賓語的關(guān)系代詞that或which。主句中may用倒裝語序表示祝愿。例如：May you succeed!祝你成功!May you be happy!祝你幸福!May God bless you!愿上帝保佑你!as用作連接詞表示時(shí)間關(guān)系，用來引導(dǎo)時(shí)間狀語從句，意思也是“當(dāng)?shù)臅r(shí)候”，往往可與when或while通用，但它著重指主句和從句中的動(dòng)作或事情相并發(fā)生。例如：I saw him as he was getting off the bus.當(dāng)他下公共汽車時(shí)，我看見了他。As he walked on，he felt himself getting more
