答案】。

大声嚷以便让自己的声音能被听到。

【答案】。

本句考查非谓语动词的用法。

分词短语做状语，因为主语和分词之间的关系是被动关系，因此用过去分词。

【答案】本题考查固定用法：根据……判断。

a > ”【答案】在告别时，应该说“' .或' .很高兴（已经）见到你。

其中' .更常见，两种形式同为备选项时，优先选择完成形式。

在见面时则应该说' .很高兴（要）见到你。

另外固定搭配：“对……感到满意”。

【答案】。

项和项中的和均为否定含义，与句意不符，排除。

项为. 用法，意思是：“还剩下……”。

这里的意思是“还剩下几个美元”，的过去分词是，它的宾语是前面的。

句意为：我们买票吧，尽管我们这只剩几美元了。

：尽管。

是：“我们要求把产品的样品送来，然后我们可以做出决定。

【答案】。

本题考查的是 . ，主动形式是.此处是允许人们在硫含量低的情况下燃烧煤和石油，所以它们是被燃烧，用被动。

【答案】。

本题考查固定用法。

尚待分晓。

首先 （老夫妇去旅游这件事 ）还有待于观察，表将来用不 定式。

这件事情是被观察，因此选被动。

综上选。

答案】。

新技术的目的是让生活变得更容易，而不是变得更难。

不定式作表语。

答案】。

一个人累了之后还能走很远。

【答案】 本句考查非谓语动词做宾语补足语，又因为宾语和宾语补足语之间是逻辑上的动宾关系，因为是将来式， 所以用动词不定式做宾补， 因此用动词不定式的被动。

本句的意思答案】飞行员要求飞机起飞时，所有的乘客在座位上坐好。

答案】。
