问题 Alight with no more power than ______ by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam.
选项 A、as is produced
B、that produced
C、that is produced
D、produced
答案 B
解析 相当于A light with no more power than the power that is produced by... that 代替power，表示相比较的事物，而D中没有比较对象，故不对；as 表示原级比较，不与than 用在一起，故A也不正确；C中缺少that 的先行词，也是错误的。
