问题 The scientists have conducted a series of experiments.
选项 A:actions       
B:tests
C:effects

答案B
解析科学家们已经进行了一系列的实验。action“行动，活动”，如：The government is taking actions to deal with a housing crisis．政府正在采取行动解决住房危机。test“试验”，如：I try to finish the test within ten minutes．我试图在10分钟之内完成这项试验。 effect “影响”，如：The sunshine has many effects on the skin．阳光对皮肤有很多种影响。technology “技术”，如：Science and technology are the primary productive force．科学技术是第一生产力。只有tests意思上和experiments最接近。
