翻译：学生的成绩在采用了交互式计算机教学后有了提高，这一事实并不足以说明新的教学方式对提高成绩有帮助。

[1] Necessarily: UNAVOIDABLY; as a logical result or consequence，“必然地”、“一定地”，经常用在否定的情况下，如：“未经证实的谣言并不一定是假的”，An unconfirmed rumor is not necessarily false.

[2] Imply有“暗指，暗示”的意思，其实也可以解释成“必然包含，必需”的意思。如：“戏剧必有冲突”，Drama implies conflict;“要达到他的目标需有充沛的精力”，His aims imply a good deal of energy.
