of what to do now. I must find a new way to provide for us.Frightful is going to be in good hands at the university, and she will have young.

When I am far above the river, I take off my clothes and moccasins (鹿皮鞋) and bathe in a deep, clear pool until I am refreshed and thinking more clearly.Climbing up the bank, I dress and sit down.I breathe deeply of the mountain air and try to solve my problem more realistically.

C．Complicated character relationship. D．Ever-changing story events.

6．What is Sam's first worry? A．The shortest way to go back. B．Survival for Alice and himself. C．The safety of Frightful. D．How to get enough venison.
解析：选B 推理判断题。根据first worry定位到第二段中的“I have a problem.I have to provide my younger sister Alice and myself with meat.Fish, nuts, and vegetables are good and necessary, but they don't provide enough fuel for the hard physical work we do.”哥哥思考的是如何给自己和妹妹提供肉，因为有肉才能提供足够的能量去做体力活。所以哥哥的担忧是如何让自己和妹
妹活下去。

解析：选B 推理判断题。根据第一段第一句中的“start thinking about what to do now that you have lost your falcon (猎鹰), Frightful.”可知：失去了Frightful，你就必须思考接下去该怎样做，然后第二段又提到作者面临的问题是如何给自己和妹妹提供肉，所以Frightful在丢失之前帮助过他捕猎。

B．Aggressive. D．Unrealistic.
解析：选C 推理判断题。作为哥哥他苦恼着自己与妹妹的生存，考虑着他们未来的食物来源可见，他是十分负责任的。
C
(2020·徐州、淮安、连云港一模)When a caterpillar (毛虫) pretends to be a snake to keep off potential predators (捕食者), it should probably expect to be treated like one.This is exactly what happened in Costa Rica earlier this year, when researchers witnessed a hummingbird defending its nest from what it interpreted to be a snake, but was actually a caterpillar, which was feeding on a leaf above the nest.
These caterpillars resemble flat dried leaves as adults.They can expand the top of their heads to expose a pair of eyespots that discourage potential predators.When disturbed, they raise their head up and move from side to side, increasing the snake like appearance.In particular they resemble a green parrot snake, known to feed on nesting birds.
Hummingbirds have a few styles of flying: visiting flowers, feeding on
some tiny insects, chasing each other, and mating territory (领土) display flights.Mobbing (围攻) behavior directed against a threat to their nest is much less common but easy to recognize if you know their flight behaviors.
The interaction of the caterpillar and the humming birds took place in Costa Rica.The comings and goings of the female hummingbird around its nest may have disturbed the caterpillar, causing it to expose its eyespots, which in turn caused the hummingbird to defend its nest using what is referred to as “mobbing behavior” by birds.
The caterpillar was unable to feed during the 26 minutes of nearly continuous attacks.Most of the bird's movements were cautious, but included quick attacks to peck or bite the eyespots.
It was difficult for either the bird or caterpillar to withdraw from the standoff
(僵局), with the hummingbird protecting
its nest and the caterpillar just trying to finish its leafy meal.Eventually the caterpillar gave up on eating and crawled away while still under attack, and the hummingbird continued normal nesting behavior.
When birds exhibit this mobbing behavior targeting snake's eyes, it often ends with snakes being killed by repeated bites and pecks near the head.As for creatures that imitate snakes to protect themselves from being eaten, can they in turn protect themselves? Because the hummingbird behavior was typical anti-snake behavior, it can be considered replicable (可复制的)．
Future studies of this behavior can be conducted using a tiny, caterpillar robot.It should be remote controlled, light enough to attach to a leaf or stem, and wireless.With such a robot, researchers could vary the eye like nature and contrast of spots on the head of the robot to test various responses of nest-defending birds.A study like this could definitively test the effects of eye like versus other imitating patterning for exciting the defensive attacks.
And, it turns out that the caterpillar feeds on a leaf on the same plant, as far away from the nest as possible!
语篇解读：本文主要讲述了毛虫为了保护自己装扮成蛇吃鸟巢上面的树叶而蜂鸟为了保护自己的巢穴围攻毛虫，二者为了各自的利益互不退缩的故事。 9．What do we know about caterpillars and hummingbirds from the passage? A．They belong to the same species. B．They are natural enemies of each other. C．They are insects and birds respectively. D．They compete against each other for territory.
解析：选C 细节理解题。根据caterpillar后面括号内的中文注解以及hummingbirds这个单词中的bird就可以知道他们分别是昆虫和鸟儿。
10．Hummingbirds will show their mobbing behaviors when visitors ________.
A．are picking flowers B．are chasing each other C．interrupt their eating leaves D．set foot on their territories
解析：选D 推理判断题。根据mobbing behaviors定位到文章第四段最后一句“... which in turn caused the hummingbird to defend its nest using what is referred to as ‘mobbing behavior’ by birds.”可知，蜂鸟用鸟类的“围攻行为”来保卫自己的巢穴，所以当游客侵犯他们的领地的时候，他们会围攻游客。
11．Why is neither the hummingbird nor the caterpillar willing to withdraw at first?
A．Because the hummingbird is trying to finish its leafy meal. B．Because the caterpillar is protecting the hummingbird's nest. C．Because they behave in this way out of their own interest. D．Because there is a green parrot snake watching them.
