Question

【題目】Hummingbirds are birds from the Americas.They are among the smallest birds.They get their name from the humming sound they make as they fly.

Hummingbirds live mostly on nectar(花蜜)，a kind of sugar water found deep inside flowers.Drinking nectar almost all day long gives hummingbirds the energy they need to keep their wings beating fast，typically around 3，000 times a minute.Hummingbirds' hearts beat fast，up to 1，260 times a minute(yours beats about 70)．And they breathe about 250 times a minute.So they need a lot of energy.This means that hummingbirds need to eat almost all day long.They fly from flower to flower，seldom at rest.

As a hummingbird feeds，its beak(鳥喙) and face get covered in pollen(花粉)．When the bird visits their flower，some pollen falls off.Hummingbirds help the flowers by spreading pollen around from plant to plant.It's a fair trade：the hummingbird gets a meal and the plant gets to make seeds(種子)．

For humans，eating sugar all day would lead to serious health problems.Our bodies could not deal with that much sugar.But hummingbirds burn their sugar as quickly as they eat it，so it doesn't become a problem.In fact，hummingbirds don't live on nectar alone.They also eat a lot of insects and spiders.And maybe with enough nectar，the spiders don't taste quite so bad.

【解析】

蜂鳥是來自美洲的鳥類，它們是最小的鳥類之一，它們的名字來源于它們飛行時發(fā)出的嗡嗡聲，這篇文章介紹了蜂鳥的相關情況。

【1】句意：蜂鳥的心臟最快的跳動是如何的？原文“.Hummingbirds' hearts beat fast，up to 1，260 times a minute(yours beats about 70)”（蜂鳥的心臟快速跳動，每分鐘高達1,260次（你的心臟大約70次）），這里描述了蜂鳥心臟跳動情況，故填：Up to 1,260 times a minute.

【2】句意：蜂鳥如何幫助植物來產(chǎn)生種子的？原文“Hummingbirds help the flowers by spreading pollen around from plant to plant.”（蜂鳥通過在植物之間傳播花粉來幫助花朵。），這里講了蜂鳥幫助植物產(chǎn)生種子的方法，是通過植物之間傳播花粉，故填：By spreading pollen around from plant to plant.

【3】句意：為什么對于蜂鳥來說，全天吃糖不是一個問題？原文“But hummingbirds burn their sugar as quickly as they eat it，so it doesn't become a problem.”（但是蜂鳥會在吃它們的時候盡快燃燒糖，所以這不會成為問題。）說明了蜂鳥可以全天吃糖不是什么問題的原因，故填： Because hummingbirds burn their sugar as quickly as they eat it.
