  • 第1题：

    Why do German and French babies produce different types of cries according to the research?

    A.Because they can control what they hear.
    B.Because they can control their different breathing patterns
    C.Because they don't share the same physiological structure
    D.Because they can somehow control their sound production.

    答案：D
    解析：
    推断题。根据原文第三段提到的“This study refutes that claim: since babies cry in different languages，they must have some control…showing that the sound of their cries isunder their control.”可知，法国婴儿与德国婴儿虽然具有相同的生理结构，但他们可以发出不同类型的哭声，这是因为他们可以控制自己的发声。故本题选D。
