问题 What concern will the test-tube baby raise according to the passage? [br] What is the author’s tone in this passage?

选项 A、Depressed.
B、Optimistic.
C、Opposing.
D、Negative.

答案 B

解析 由题干中的tone定位到原文第四段The Australian researchers report that they are quite encouraged.All the babies are now making normal progress,even the twin with the birth defects.[精析] 综合推断题[考频:28]。从encouraged,normal progress可以看出作者对试管婴儿的前景比较乐观。[避错] A)沮丧的,C)反对的,D)否定的,这三项都可以算是一类“口气”,选择其中任意一项都意味着不支持试管婴儿,故三项都排除。
