B
Swifts (雨燕) live mostly in the air. These small birds are among the fastest animals on Earth. In fact, swifts can go two or three days without touching the ground! To get used to life in the sky, swifts use their speed and the saliva (唾液) in their mouths.
Swifts can fly faster than 100 miles per hour. That’s because their wings are like boomerangs. This shape of the wings helps them to fly much faster. They can also move one wing faster than the other, which allows them to make sharp turns without slowing down. Making fast, sharp turns helps swifts catch flying bugs to eat.
The saliva helps swifts catch bugs to feed their young. It is sticky, like glue. Swifts often fly into clouds of bugs such as mosquitoes and open their wide mouths to catch as many insects as they can. The bird collects insects in its mouth gradually and holds the insects in a sticky ball of saliva. One food ball can contain nearly 1,000 bugs.
Swifts also use their saliva as glue to build their nests. The birds catch feathers in the air and stick the feathers together to build a strong nest on the side of a building. Swifts’ short feet are not good for walking or standing on land for long. But their sharp claws allow them to stick to rocks and walls so they can take a brief rest before returning their lives in the sky.

答案： 16. B【点拨】细节理解题。根据“Swifts can fly faster than 100 miles per hour. That's because their wings are like boomerangs.”以及“They can also move one wing faster than the other, which allows them to make sharp turns without slowing down.”可知第二段主要讲述了雨燕能够快速飞行和急转弯的原因，故选 B。
17. D【点拨】代词指代题。根据“The saliva helps swifts catch bugs to feed their young. It is sticky, like glue.”可知，“It”指的是前文提到的“saliva”(唾液)，因为唾液具有粘性，像胶水一样。故选 D。
