【題目】We did not know you were in trouble at that time, ______we would have given you a hand.

A. otherwise B. however

C. therefore D. though

【答案】A

【解析】考查連詞，根據(jù)句意，我們不知道那是你有麻煩，…我們會(huì)幫助你，會(huì)幫助即實(shí)際上沒有幫助，用的是虛擬語氣，故前后為轉(zhuǎn)折關(guān)系，故排除C和D。However用于句中時(shí)前后通常都用逗號(hào)隔開，otherwise用于句中其前常為逗號(hào)，其后直接跟句子內(nèi)容，故選A。
