急..英語(yǔ)語(yǔ)法填空
1.Deciding what present you should give someone is not easy.Many things must be considered such as _____ the person is interested in and how old he is.?
為什么空格處填what 后面有介詞in 不是應(yīng)該用how嗎?which呢?請(qǐng)?jiān)敿?xì)解釋3者在這里的不行與行的地方,謝謝
2.In 1900 the world's use of paper was about one kilogram ____ each person in a year.
for和of 在這里的區(qū)別,為什么用for?為什么不能用of? 謝謝哦
3.We have learnt some of the most important facts of European history from record that ____ (keep) on parchment.
我知道填被動(dòng)語(yǔ)態(tài) were kept .但是我覺(jué)得填 have been kept 也可以,詞數(shù)不限,你覺(jué)得呢?直接填過(guò)去分詞kept可以嗎?不行的話為什么呢?
再問(wèn)個(gè)地方，再加5分給你，To my amazement ,.................如果用To my amazing可以嗎？用動(dòng)名詞代替名詞？這里amaze做什么成分？
