Question

the torus's heavy ions migrate outward,and their pressure inflates the jovian magnetosphere to more than twice its expected size.5094 这个问题可能有些笨,to more than twice its expected size这个介词to后面好像直接跟了个句子.不太明白

Answer 1

1.to more than twice its expected size 是“介词 to +形容词短语 more than twice its expected size”结构
2.形容词短语 more than twice its expected size 是由“形容词比较级 more + than + 副词twice + 名词短语 its expected size”,直译过来就是“两倍地大于它的被认为的那种大小”.其中 expected 是过去分词作 size 的定语.而不是谓语动词,因此构不成句子.
3.more than + twice + its expected size 和昨天问题中的 1300 + times + that 结构是一样的,前者指“比人们认为的大小大两倍”,后者指“是那个东西的1300倍”.
翻译：其环面的重离子向外移动,重离子的压力使得木星磁层膨胀到大于人们认为其大小的两倍.
