单选题
They continued to ______ about and enjoy themselves until they became tired.
【正确答案】
B
【答案解析】[解析] 本题是说他们继续四处逛着,尽情享受着,直到他们累了。B项stroll“闲逛,漫步,跋涉于”符合题意,如:My friend likes to stroll around the flea market on the chance of picking up something of value.(我的朋友爱逛旧货市场,希望能找到点有价值的东西。)其他三项stroke“抚摸”;stammer“口吃,结巴着说出”;string“排成一列”都不正确。
