Question

Animals have their special ways to deal with hard times in nature. The superb fairy-wren, one kind of bright-blue bird in Australia, is one example. This year, a ten-year study showed that this small bird has eggs of different sizes in different kinds of weather. When the weather is hot and dry there is less food for young superb fairy-wrens, and they die easily. So the mother bird will make larger eggs to help her babies grow stronger inside before they break out of the eggs into the "hungry" world.

However, not all mother birds are able to do this. Only those with at least one male child can. When the weather is "good", the mother will make smaller eggs, and her sons will bring food back for their baby brothers and sisters from the eggs. With her sons' help, the mother can save more energy to make larger eggs when the weather is bad. Isn't this amazing?

最佳标题题。根据文章开头“Animals have their special ways to deal with hard times in nature. The superb fairy-wren, one kind of bright-blue bird in Australia, is one example. This year, a ten-year study showed that this small bird has eggs of different sizes in different kinds of weather.”以及整个文章的理解可知，文章讲述的是动物有它们特殊的方式来应付自然界的困难时期。并且举例澳大利亚的美丽鹪鹩在天气不好的时候产的蛋就大一些，天气好的时候产的蛋就小一些，目的是保证将来孵出来的幼鸟能够有能力冲出蛋壳，所以四个选项中D选项概括比较合适，故选D。

2.

词义猜测题。根据文中“So the mother bird will make larger eggs to help her babies grow stronger inside before they break out of the eggs into the “hungry” world. However, not all mother birds are able to do this. Only those with at least one male child can. ”因此，雌鸟会制造更大的蛋，以帮助她的宝宝在它们冲出蛋进入“饥饿”的世界之前，在里面长得更强壮。然而，并不是所有的雌鸟都能做到这一点。只有那些至少有一个雄性宝宝的才可以。可知这里的this指代的是“雌鸟能够产出不同大小的蛋”这件事情，故选A。

3.

细节理解题。根据文中“When the weather is hot and dry there is less food for young superb fairy-wrens, and they die easily. ”当天气炎热干燥时，幼小的鹪鹩的食物就会减少，它们很容易死亡。可知A选项描述错误；根据文章的理解可知，B选项内容在文中没有显示，所以排除B选项；根据文中“and her sons will bring food back for their baby brothers and sisters from the eggs. ”她的儿子们会把食物带回给他们的从蛋壳里出来的弟弟妹妹们。可知C选项是正确的；根据文中“When the weather is hot and dry there is less food for young superb fairy-wrens, and they die easily. So the mother bird will make larger eggs to help her babies grow stronger inside before they break out of the eggs into the “hungry” world. ”当天气炎热干燥时，幼小的鹪鹩的食物就会减少，它们很容易死亡。因此，雌鸟会制造更大的蛋，以帮助她的宝宝在它们冲出蛋进入“饥饿”的世界之前，在里面长得更强壮。可知，D选项描述是错误的，故选C。
