问题 Mr. Brown’s condition looks very serious and it is doubtful if he will______.
选项 A、pull back
B、pull up
C、pull through
D、pull out
答案C
解析 动词pull均可与选项中的介词搭配。四个词组的意义分别为：pull back表示“把……向后拉，反悔，(使)撤退，紧缩开支”；pull up“拔起，停下，阻止”；pullthrough“渡过难关；脱离危险期，恢复健康(=pull round)”；pull out“(火车)离站；撤离，离开”。根据前半部分的“condition(病，疾病)”可知本题选C。
