问题 What concern will the test-tube baby raise according to the passage?
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。
