is a shy man，but he is not afraid of anything or anyone.他是一個(gè)靦腆的人，但是他不害怕任何事情或任何人。名師點(diǎn)津but作連詞還可用于“Im sorry/Excuse me，but.” 句式中表示歉意，but本身沒有意義。Im sorry，but I cant help you with the problem.很抱歉，我不能幫你解決這個(gè)問題。(2)however作副詞時(shí)，表示“然而，可是，不過”，用以引出令人吃驚或表示對(duì)比的話語，可放在句首、句中或句末，但要用逗號(hào)隔開。Id like to go with you，however，my hands are full.我很想和你一塊去，可是我太忙了。You may be right.However，I

和though的用法(1)although和though都是引導(dǎo)讓步狀語從句的從屬連詞，意為“盡管，雖然”，一般情況下可互換。但although較正式，多用于句首，而though在非正式文體中較為普遍。Although/Though these measures are not effective forever，they are vital for now.雖然這些措施并不能永遠(yuǎn)有效，但它們目前是至關(guān)重要的。名師點(diǎn)津although和though都不能和并列連詞but連用，但可以和yet或still連用。(2)though引導(dǎo)讓步狀語從句時(shí)可用部分倒裝形式，其用法相當(dāng)于as，把從句中的表語、狀語或動(dòng)詞原形置于句首；若表語是可數(shù)名詞單數(shù)，前置時(shí)要省略不定冠詞。Hot

stone.盡管我用盡力氣，還是搬不動(dòng)那塊石頭。名師點(diǎn)津though還可以作副詞，放在句末，用逗號(hào)和主句分開，相當(dāng)于however，意為“然而”。She said she would come；she didnt，though.她說她要來，然而卻沒來。即時(shí)演練2一句多譯他雖然成功，但不驕傲。Although/Though he is

means disagreement.揮手表示再見，點(diǎn)頭表示同意，而搖頭表示不同意。(2)while引導(dǎo)讓步狀語從句，意為“雖然，盡管”，可以與although或though互換，此時(shí)while位于句首。While online shopping has changed our life，not all of its effects have been
