参考答案
1.B
【句意】假说和理论的构建反映了科学家对所观察到的现象的解释。
【解析】名词词义辨析。prototype“原型，雏形;样机”;hypothesis“(其复数为hypotheses)假说;猜测”;fantasy(其复数为fantasies)“幻想;想象”;imagination“想象力;想象”。由句中关键词“construction构建”与“theories理论”的对应知“假说”符合语境，故B项正确。
2.A
【句意】要不是她的男朋友抓住了她，这个女孩本来会掉进湖里。
【解析】语法结构——与过去事实相反的虚拟语气。由句中关键词“but that her boyfriend caught her要不是她的男朋友抓住了她”的对应知这里表示与过去事实相反的虚拟语气，由这类虚拟语气的固定模式“条件从句的谓语用‘had+过去分词’，主句的谓语用‘would (should/could/might)+have+过去分词”知A项“would have本来会”正确。
