1.听写包 答案：

Listen to part of a lecture in a biology class.

I’d like to continue our discussion of animal behavior, and start off today’s class by focusing on a concept we haven’t yet touched upon: swarm intelligence.
Swarm intelligence is a collective behavior that emerges from a group of animals like a colony of termites, a school of fish, or a flock of birds.
Let’s first consider the principles behind swarm intelligence and we’ll use the ant as our model.
Now, an ant on its own is not that smart, when you have a group of ants, however, there you have efficiency in action, you see, there is no leader running an ant colony.
Each individual, each individual ant operates by instinctively following a simple set of rules when foraging for food.
Rule number one: deposit a chemical marker called a pheromone, and rule two: follow the strongest pheromone path.
The strongest pheromone path is advantageous to ants seeking food.
请听生物学课上的部分内容。
我想继续讨论动物行为，并通过关注一个我们还没触及的概念开始今天的课程，那就是群体智能。
群体智能是一种出现在一群动物中的集体行为，比如一群白蚁，一群鱼或一群鸟。
我们首先来看看群体智能背后的一些原则，我们就用蚂蚁作为范例吧。
单独的一只蚂蚁并没有那么聪明，但是有了一群蚂蚁就有了高效的行动，其实并没有领导者管理蚁群。
每只蚂蚁在搜寻食物时，通过下意识地遵从一套简单的规则来进行作业。
规则一：留下一种叫做费洛蒙的化学标志；规则二：沿着费洛蒙最强烈的那条路走。
对寻找食物的蚂蚁来说，费洛蒙最强烈的那条路非常有利。

3.写作包答案：

In modern society,there will be a generation gap if the gap of ages reaches 3 years.This is the so-called“Each three-year age gap,one generation gap”.In the past,people thought that generation gap appeared when the age gap reached 10 to 20 years.But in the 21st century,with the national economic development,the growth of people's cultural knowledge and the improvement of their thought and consciousness,people's individualization and self-awareness have gradually been strengthened.Communication barriers among people appear;ideas and viewpoints begin to differ from person to person,making it hard for one to find resonance with other people.This phenomenon is related to the level of economic development-the more developed a place.
