Everywhere we look, there is colour. We see it in the sky and in the sea. There are colours in all plants and animals. Colour makes our homes and schools pretty. We see it in pictures and in books. We even see colour in our food. It makes things look good.
How can we see colour? We see colour when light hits(射入)our eyes. Dogs and many other animals can’t see colours. But bees(蜜蜂) can. They even see colours we don’t see. This helps them find flowers to fly to.
We sometimes use the names of colours to say things. People may say that they “see red” when they are angry(生气). Or you may say you “feel blue”. This means you are sad. We use colour to tell things., too. Red is the colour of stop signs. It means to stop. Green means to go.
Animals come in all kinds of colours. Many of these are very pretty. An animal’s colour may say “here I am”., “stay away” or “be careful” or it may help the animal hide(隐藏). Some animals can make their colours look like the trees around them, then other animals or people can not find them.The best title(题目) of the article is _______.

We all know that foods will easily go bad if they get too warm. So we usually put them into our fridges to keep cool in hot weather. But can you make it without fridges?
In 1995, Abba, a teacher from Nigeria, found a cool way. His invention was called Pot-in-Pot Cooling System.
It uses two clay pots (陶罐). There is a smaller pot inside a larger one. The space between the two pots is filled with wet sand. Fruit, vegetables or drinks can be put into the smaller pot. A wet cloth covers the whole cooling system. Some foods can be kept fresh for several weeks in it.
Abba built five thousand pot-in-pot systems for the villagers in his hometown. Then people all over the country began using the invention. Soon it became popular with farmers in other African countries.
In 2000, Abba got a prize --- the Rolex Award. If you are trying to do something to improve human life, you may have the chance to get this prize.Who is Abba?
Where should we put fruit and drinks in the Pot-in-Pot Cooling System ?
What can farmers use Abba’s invention to do?
How many pot-in-pot systems did Abba build for the villagers?
From the passage, how can we have the chance to get this kind of prize like Abba?

Do you know something about tree rings? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?
A tree will grow well in a climate with lots of sunshine and rainfall. And little sunshine or rainfall will limit the growth of trees by studying the tree rings. For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside. If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year. If it is near to the eleventh ring, then the climate that year was bad.
Tree rings are important not only for studying the history of weather but also for studying the history of man. Many centuries ago, there lived a lot of people at a place in New Mexico. But now you can find only sand there－no trees and no people. What happened?
A scientist studied the rings of dead trees there. He found that the people had to leave because they had cut down all the trees to make fires and buildings. As all the trees had gone, the people there had to move.
Tree rings can tell ______ according to the passage.
A. whether a tree was strong or not.
B. whether the climate was good or not
C. how tall trees used to be.If you want to find out the weather of twenty years ago, you should study ________.

C. The people left the place in New Mexico because the land became sand.The passage mainly tells us ________ .
A. how climate affects the growing of trees

At most school, “going green” means less rubbish or recycling. But at New York’s Riverdale Country School, it means being advised to run and even jump in the hallways. And the students really enjoy doing that.
Why? It because the hallways were built with special kinetic(动能的)tiles. When students run or jump on the floor tiles, electricity will be generated(产生). The electricity can be used to power classroom lights, science projects and charge electronic products. 14-year-old Zach Halem tried to make the officials buy them. There are eight tiles near the school’s student center.
Besides providing fun green energy, it’s also a good way to teach the students to be creative. They will be inspired to be scientists, inventors and engineers in the future to find clean energy for all humans.
The tiles are mostly made from rubber and other recycled things. They were invented by an English man Laurence Kembell-Cook. While new to the US, They have been put in many places in Europe- from a London Underground Station during the 2012 Olympics to a marathon (马拉松)track in Paris. When Pavegen started getting popular in London schools, Laurence began to realize that his invention not only saved energy ,but was also fun!Why do the students of New York’s Riverdale Country School enjoy running in the hallways?
