as long as 与only if 的用法区别，as long as,单词记忆法、语法用法、单词意思，与as long as, 相关例句、名人名言-语法综合

二、语气上的差别
从语气上看，only if 的语气要比as long as 强，as long as 通常只是用于提出一个条件，与if 的意思比较接近；而only if 引出的从句内容则通常暗示它是主句内容的唯一条件，含有“只有……才……”“只有在……的时候”“……唯一的条件是……”之意。比较：
As long as you do your best, we’ll be happy. 只要你尽力，我们就满意了。
You can borrow the book as long as you keep it clean. 只要你不把书弄脏，这书你就可以借。[2]borrow,keep,相关知识点

borrow/ lend /keepⅢ. keep 表“借多长时间”，时延续性动词。可用于完成时态。而borrow 和 lend 是短暂性动词。则不能用于完成时态，或与表段时间的状语连用。如：① He has kept the books for two weeks.他借这书两天了。② ---How long can I keep the book? ---Two week

We can succeed only if everyone in the team pulls his weight. 我们全队只有人人各尽所能才能取得成功。[3]everyone单词记忆法

◆记忆方法一：联想方式：every（每个的）；one（一个人）记忆方法：everyone（每个人）。（复合词）

The coach stops at the principal hotels to pick up tourists, but only if they arrange this in advance. 大客车到各主要的旅馆来接观光者，但条件是必须事先安排好。
三、动词搭配上的差别
在许多情况下，as long as 与 only if 均可用，只是语气有强弱之分。但是，当主句和从句的谓语动词均为短暂性动词时，通常只用 only if，而不用 as long as。如：[4]谓语动词,动词,相关知识点

谓语动词切忌用“行为动词1 + 原形动词”、“be + 原形动词”。○4have+过去分词。如：Many trees have been cut down since 1970s.（意思同上）○5般时问句和否定句中：do/does/did+原形动词。如：He does not enjoy himself very much.（他日子过的不好。）Did any of you se

你只有请他，他才会来。
误：He will come as long as you ask him.
正：He will come only if you ask him.[5]will单词记忆法

◆记忆方法一：联想方式：w 胃；ill 病记忆方法：胃病将会影响你的胃口

析：此句中的 only if 不能用 as long as 代替，因为动词 ask 与 come 均短暂性动词。
