How Life Changes

Great changes have taken place in our life for years. Let's have a look at these examples.

In the past, people read newspapers, listened to the radio and watched TV news and other information. People kept in touch with each other mainly writing letters or sending postcards. They would buy everything in the shop or market. Big families had to share small houses were old and dirty. Children used to go to school by bike.

But now people can get information on the mobile phone or computer almost any place and at any time. They can buy things online at home. What's more, people can others by email, WeChat or QQ, with which they can send and  messages whenever they like. More and more people live in and clean apartments with several rooms. More families are rich enough to send their children to school  their own cars.

In a word, thanks to the social progress, people live better than before. Let's cherish what we have today.

Creativity (创造力) is the key to a bright future. Here is1schools and parents can help their children to develop their creativity.

Drew worked for a company in 1925. At work he invented a kind of material 2 enough to hold things together. But his boss told him not to think more about the idea. Drew didn't stop and finally, using his own time, made a kind of tape, 3 now is used everywhere by many people. And his company learned from its 4 .

Now the company asks its workers to 5 15 percent of their work time just thinking about and developing new ideas.

Creativity is not something 6 is just born with. A person with high intelligence does not mean that he uses it creatively. Creativity is the matter of 7 your intelligence to think of new ideas that are good for something.

We know that many schools have tried to8 students' creativity, but some teachers only want to develop students' reading, writing and maths skills, and have to 9 creativity for correct answers. Children from such schools can give correct answers, but they are unable to use 10 to work out problems.

It is important to give children choices. From the earliest age, children should learn to make decisions and understand their 11 Even though it's choosing between two kinds of food 12 lunch, decision- making helps thinking skills.13 children grow older, parents should let their children decide how to use their time or spend 14 money.

On a sunny day, a yellow school bus headed for Elver Park in Madison, Wisconsin. The seventh graders took their rockets (火箭) , notebooks and pencils with them. At the park, they prepared, their rockets for take-off. They waited for their teacher's signal (信号) to start the countdown: 5, 4, 3, 2, 1, GO!

"With the rocket unit, 1 taught the basic principles (原理) of physics," explained David Ropa. He teaches science at Spring Harbor Middle School.

"Kids, like all humans, are doing science all the time. They discover the world through play whether they're playing with toys or playing with sand on the beach. They have an idea. They set up a test. They study the results. Then they improve their methods, "said Ropa.

In fact, kids stay more confident about "doing science' when their teachers use those words. Talking about "being scientists" actually may lower their confidence. After all, science isn't just for scientists. Cooks, musicians and gardeners often use textbook knowledge of science in the real world.

Leslie Hunter is also interested in science. But she's growing plants, not building airplanes. She started her own vegetable garden at the age of eight. Her parents prepared the land, and she did everything else.

In college, Hunter learned the science of growing flowers, fruit and vegetables. Today she works at the Greater Des Moines Botanical Garden in Lowa. Hunter uses science to grow plants. The science of plants helps her manage the garden well.
