听力原文: There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do.
In the ancient world, as today, most boys played with some kinds of toys and most girls with some other. In societies where social roles are rigidly determined, boys pattern their play after the activities of their fathers and girls after the tasks of their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world.
What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality of toys with regard to their development in all part of the world and their persistence to the present that is amazing. In Egypt, America, China, Japan, and even among the Arctic peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.

A.Because boys and girls are being prepared for different social roles.
B.Because boys are more courageous.
C.Because toy makers want to diversify their products.
D.Because parents have different expectations for boys and girls.

It happens to all of us sometimes, doesn’t it? You have a deadline to meet,but instead of doing your work, you check Facebook or do some on line shopping.This is called procrastination, and it affects everyone.So how can you stop procrastinating?
We often procrastinate because a task seems too big, or impossible to achieve.Try breaking down the task into smaller pieces.For example, instead of thinking,“I need to finish this essay by 10 p.m.tonight ” tell yourself,“I’ m going to make a short outline, fill that in, and then look for quotes.”
Another important factor is your environment, isn’t it? If there are too many distractions in your work space, you may be tempted to procrastinate more.Are there any things in your work space (for example, a TV) that could be causing you to lose focus?
Making a timeline with goals and deadlines is a great way to stop yourself from procrastinating.
However, it is important to make your deadlines realistic so that you can be sure you’ll stick to them.
Some people like to wait for the perfect time to start a task, while the perfect time is often now.Try something called the Two-Minute Rule to help you get started.This idea comes from David Allen’ s best-selling book, Getting Things Done.It states that.if something takes less than two minutes, such as washing your dishes after a meal, then you should do it now.
