Question

I posted the letter some time _____ the week .

A．in

B．during

C．throughout

D．within

Answer 1

B

介詞during后面總是一個(gè)表示時(shí)間的名詞，這一句詞可以指整段時(shí)間，如：It was very cold the winter (整個(gè)冬天，天氣都很?chē)?yán)寒。)這一名詞也可以指一段時(shí)間中的時(shí)點(diǎn)或時(shí)刻，如：She has phoned him four times during the last half an hour . （在剛才的半個(gè)小時(shí)內(nèi)，她給他打過(guò)四次電話(huà)。）在這個(gè)例句里during可以被介詞in代替，因?yàn)閕n具有within a period (在一段時(shí)間內(nèi))的意思。但在以下兩種情況下不能用in代替during。（1）當(dāng)所提及的是一個(gè)事件或一項(xiàng)活動(dòng)，而不是一段時(shí)間時(shí)，如：I didn't learn much during my teacher training . (在教師培訓(xùn)中，我沒(méi)學(xué)到多少東西。)；（2）在表示不明確的時(shí)間時(shí)，用some time + during…表示，如：I dropped in on him some time during my visit the city . (在我觀光那座城市時(shí)，我曾順便看望過(guò)他。)
