标题: prep1-86 estimate的用法

86. (29247-!-item-!-188;#058&003883)

An international team of astronomers working at telescopes in the Canary Islands and Spain has

detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter, the

solar system's largest planet.

(A) astronomers working at telescopes in the Canary Islands and Spain has detected at least 18

huge gas spheres estimated to have 5 to 15 times the mass of Jupiter

(B) astronomers working at telescopes in the Canary Islands and Spain has detected at least 18

huge gas spheres estimated to be 5 to 15 times Jupiter's mass

18 huge gas spheres that are estimated at 5 to 15 times the mass of Jupiter

(D) astronomers, working at telescopes in the Canary Islands and Spain, and has detected at least

18 huge gas spheres estimated at 5 to 15 times the mass of Jupiter

(E) astronomers, working at telescopes in the Canary Islands and Spain, has detected at least 18

考点:简洁有效（Rhetorical Construction）平行对称（Parallelism）比较（Comparison）

1)不能随意更改原句的意思

2)习惯用法: estimate at 后常用价格等数量词,除此以外的概念优先用 estimate to

以上为PREP笔记的摘录，在MHT idiom中，只有ESTIMATE TO BE的搭配，ESTIMATE AT的搭配是错误的。这里正确答案的搭配是esrimate to have. 求教各位CDer estimate的正确用法是什么？
