為固定短語(yǔ)，意為“確切地說(shuō)；實(shí)際上”，通常出現(xiàn)在句子的開頭或中間，用于引導(dǎo)并強(qiáng)調(diào)即將提到的信息是真實(shí)可信的。它也可以出現(xiàn)在句子的末尾，用于總結(jié)或強(qiáng)調(diào)前面所說(shuō)的內(nèi)容。⑵without作介詞，表否定，意為“無(wú)；沒(méi)有”。①用在否定詞之后，表示強(qiáng)調(diào)肯定：without用在no,not,never等否定副詞之后，表示強(qiáng)調(diào)肯定，意為沒(méi)有······不、沒(méi)有······則不能······、每······必定······。例如：Thereisnosmokewithoutfire.無(wú)風(fēng)不起浪。②與動(dòng)名詞形式連用：without與動(dòng)名詞形式連用，表示不、無(wú)、沒(méi)。例如：Hewalkedpastmewithoutspeaking.他從我身旁走過(guò)，一句話也沒(méi)說(shuō)。③表示條件：without有時(shí)表示條件，意為若無(wú)、若非。這樣用時(shí)，有時(shí)還可引出虛擬語(yǔ)氣，相當(dāng)于butfor。例如：Withoutyouradvice,Iwouldhavefailed.假若沒(méi)有你的勸告，我想必已失敗了?！咎骄俊?dǎo)學(xué)】2.Inordertostorehoney,theycreatehoneycomb.為了儲(chǔ)存蜂蜜，它們建造了蜂巢?！揪湫推饰觥縤norderto

意為“為了······”，表示目的。后面直接接動(dòng)詞原形，整個(gè)句子是非謂語(yǔ)結(jié)構(gòu)，屬于動(dòng)詞不定式作目的狀語(yǔ)。eg:JackandHelenhaddroppedbehindinordertobealone.為了單獨(dú)待在一起，杰克和海倫故意落在后面?！就卣埂縮othat

意為“以至于；為了”，有時(shí)可與inorderthat互換，多用于非正式語(yǔ)體，sothat后面接從句?！緦W(xué)以致用】Tomhastogetupearly
