Light gets through, and this is 【C2】_____ for plants to make the food 【C3】_____ we eat. Heat, too, makes our environment endurable. Various kinds of rays 【C4】_____ the air from outer space, 【C5】_____ enormous quantities of radiation from the sun are 【C6】_____ off.

选项
A、pull through
B、put through
C、go through
D、come through
答案
D
解析
考查动词词组。文章提到,各种来自外太空的射线穿过大气层,come through“穿过,穿透”符合句意,故选D。pull through“恢复健康;克服困难”,put through“实行;接通(电话)”,go through“检查;经历,遭受”,均不符合句意,可排除。
