Question

____________better ways for digging tunnels__________, the first railway tunnel under the River Thames     was dug in 1884.

A．As , developing	B．With, developed
C．As , were developed	D．With, development

Answer 1

C

試題分析：考察as和with用法。As是連詞表示隨著；with是介詞，后面接復(fù)合結(jié)構(gòu)“with+賓語(yǔ)+賓語(yǔ)補(bǔ)足語(yǔ)”；本句可以使用“As  better ways for digging tunnels developed”；也可以使用“with better ways for digging tunnels developing”；句意：隨著更好的挖掘方法的改善，第一條泰晤士河底的隧道在1884年開(kāi)通了。故C正確。
點(diǎn)評(píng)：這兩個(gè)詞都可以表示“隨著…”；as是連詞，后面要接句子，而with是介詞，后面要接復(fù)合結(jié)構(gòu)“with+賓語(yǔ)+賓語(yǔ)補(bǔ)足語(yǔ)”。
