英语语法填空.The machine measured such a high reading ----- it beg

答：such +名词+that-（结果状语从句）是一个非常有用的句型,译作：这样的一个.以致于.
译：这仪器测得的读数是如此之高以致于它开始剧烈地振动,最后爆炸了.
as 可以引导时间状语,但一不和such连用,二不符合逻辑：
译：当仪器开始开始剧烈地振动,最后爆炸时,它测得了这样的一个高的读数.
如果是such+先行词+as-引导的限制性定语从句,则as在从句中应作主语或宾语的.而it began shaking adn exploded并不需要宾语.所以用as是错误的.
本题确有难度.

改自下文：
Once upon a time,in a small country,people decided to investigate what it was that parents really liked the most.A competition was organised.It would use the latest invention of Professor Crank-Shafte:the Gladometer.
To date,the Gladometer is the only contraption ever built capable of measuring joy and happiness.So,one by one,the children demonstrated their own particular talents to their parents.And the Gladometer faithfully measured their parents' reactions.One boy turned up with a trained pig; the pig sang and danced.A girl came and played the violin like an angel,and an intelligent boy came and read his very big book.The parent's happiness was plain to see.Finally,a boy came to the Gladometer carrying nothing.Nor did he know how to do anything.When the organisers asked him what he was going to do,he simply said:"I am very obedient."
This said,the machine measured such a high reading that it began violently vibrating,and finally exploded.The boy who had done nothing won all the prizes that day,for solving the mystery of what pleases parents the most.
