A．Since

B．While

C．Unless

D．Though

Answer 1

A

試題分析：A.Since既然       B. While當(dāng)…時(shí)候    C. Unless 除非  D. Though盡管；句意：既然你必須做這份工作，你就應(yīng)該盡最大的努力把它做好，即使對(duì)你來(lái)說(shuō)很困難。故選A
點(diǎn)評(píng)：此題考查連詞的表面意思，并不難。對(duì)于此類連詞詞義辨析的題目，首先應(yīng)著眼于句意的理解，在理解句意的基礎(chǔ)上結(jié)合四個(gè)選項(xiàng)的意思，采用排除法，得出最符合題意的一項(xiàng)答案。在平時(shí)的學(xué)習(xí)中要勤積累，并掌握這些連詞的常用用法。
