一、词义辨析：
hypothesis,assumption,presumption,supposition
这些名词均有“假设，假想”之意。 hypothesis书面用词，指有待作进一步检验或证实的假设。 assumption侧重主观推测或主观设想。 presumption着重指以可能性为依据的假设。 supposition可与assumption换用，还可表某种试探性的主观看法或建议。
二、参考例句：
We must not condemn her on pure supposition.
我们不能单凭臆测而谴责她。
She was charged on the supposition that she had colluded with her husband in the murders.
她被指控涉嫌与丈夫合谋杀人。
