1.almost=very nearly,表示"幾乎、差不多",?？苫Q使用.例如:
　　It's almost/nearly ten o'clock.差不多10點(diǎn)了.
　　He fell off a tree and almost/nearly died.他從樹上摔下來,幾乎喪命.
　　析:從事實(shí)角度講,almost比nearly的差距更小.從說話人的心理角度來講,almost暗含"還有距離",nearly暗含"似無差別".比如上面的例句,第一句用almost比nearly反映出時(shí)間更接近10點(diǎn),但用almost反映出說話人的心理活動(dòng)是"還差一點(diǎn)兒才到10點(diǎn)",若用nearly則反映出說話人的心理活動(dòng)是"可以說已到10點(diǎn)了".第2句也是這樣:用almost反映出說話人的心理活動(dòng)是"還活著";用nearly反映出說話人的心理活動(dòng)是"快死了".所以用almost,還是使用nearly,說話人的心理活動(dòng)是關(guān)鍵..
　　2.almost和nearly可互換使用的場(chǎng)合
　　(1)在肯定句中
　　The old man is almost/nearly 90 years old.這個(gè)老人快90歲了.

　This word is to be found in almost any dictionary.這個(gè)詞幾乎在任何一本詞典中都可以查到.
