6、 by bike.常用句式有 It + be+ 名詞+ to doIt s our duty to take good care of the old. It takes sb+some time+to doHow long did it take you to finish the work?

10、feel等要以不帶 to 的不定式作賓補(bǔ)。Let' have a rest.我們休息一會(huì)吧。I saw him come in. 我看見(jiàn)他進(jìn)來(lái)了。感官動(dòng)詞后既可跟不帶to的不定式作賓補(bǔ)，也可跟 v-ing作賓補(bǔ)，前者表示動(dòng)作的全部過(guò)程已結(jié)束；后者表示動(dòng)作正在進(jìn)行。I saw him come downstairs.我看見(jiàn)他下了樓。（說(shuō)明他下樓了這件事）I saw him coming downstairs.我看見(jiàn)他在下樓。（說(shuō)明他下樓時(shí)的情景） 動(dòng)詞不定式作定語(yǔ)1 不定時(shí)要放在所修飾的名詞、代詞之后。Would you like something to eat?He has a im
