When our son Peter was twelve, the new bicycle he had received was stolen. Owning a bicycle was big fun to our children when they were little. They spent hours and hours, day after day, on their bicycles, riding up and together as a family a lot. Bicycling was a great way to get the kids out of the house and into the fresh air without spending the money.
When Peter and his sister went outside for a morning ride, he discovered that his bicycle had been stolen from our backyard. He couldn't believe that someone would do this.
He got a large piece of cardboard, painted a sign begging for the bicycle to be returned, and tied the sign to the letterbox. The following morning, when I went out to collect the mail, I found a white envelope with the magical words, "Buy yourself a new bicycle". There was a $ 100 banknote inside.
We were very touched that someone had the heart to do this. We'd never been able to thank the person but we guessed that it may have been one of our wonderful neighbors. Peter painted a big "Thank you!" on the sign and we left it outside for a couple of weeks afterwards, hoping the kind stranger would drive down our street and see it.
Peter was able to own a new bicycle again. As the years went on, the bicycle became older but remained just as important as before. Now Peter is 25.
All these years later we are still thankful for the stranger's kindness. We were a young family with three little children and it meant a lot to us. We still talk about it and, even now, wonder who the kind stranger was.

From red apples and yellow lemons to blueberries and green melons, fruit comes in many different colors. 1..
According to Lu Wei from the Chinese Academy of Sciences, fruit colors actually come from their different pigments（色素）.These pigments appear differently, depending on the fruit's environment. 2..
To find out how environment influences fruit colors, Chinese scientists studied more than 280 different fruit colors. They found that red fruit usually grow in cooler places. And instead of just growing in one place, you can find them growing in many places around the world. 3.. These fruits grow a lot in just one certain area. The scientists also found that the closer the fruit is to the equator（赤道）, the darker its color will be.
4.. Animals eat fruit and drop the seeds（种子）in other places later. This helps the fruit spread and grow in different places. Therefore, in order to attract animals, some fruit develop colors that are easy for animals to see.
However, animals see colors in a different way.5.. For example, birds can see red more easily than humans can. Therefore, there is more red fruit in areas where birds live. The lemurs（狐猴）of Madagascar are red-green color-blind. Many yellow fruit can be found there, as they can easily see this color.

When throwing away rubbish, do you know which dustbin it should go in? Have you ever noticed the differently-colored dustbins on the street?
Some of you might not be able to answer this question. However, it's actually quite important to know how to sort（分类）your waste. Not knowing how to sort waste can make it harder to save energy and protect the environment.
If you don't sort your rubbish, all of it will go to a landfill（垃圾清理场）and be buried together. These landfills can take up large areas of ground that could have been used for planting trees or crops. The electronic waste you throw away, such as batteries, can pollute the soil and groundwater. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.
With this in mind, many cities in China have been running waste-sorting campaigns（活动）in recent years. for example, Shanghai announced in 2018 that within three years（2018—2020）, all the people living in Shanghai should sort their rubbish into four groups: wet, recyclable, harmful and dry.
Wet waste is also known as household waste. They are things you don't want but that pigs can eat. Paper, metal, glass and other things that can be reused are recyclable waste.
Many other Chinese cities, including Shenzhen, are using this method to sort their rubbish. Now that you know this, perhaps you can do your part to protect the environment and encourage others to sort their rubbish.
根据短文内容，判断下列句子正（T）、误（F）。
1.If you know how to sort waste, it will help us save energy and protect the environment.
2.Shanghai will achieve the goal of sorting their rubbish into four groups in 2020.
3.The food that we haven't finished eating at home belongs to recyclable waste.
4.Many cities in China are doing waste-sorting work nowadays.
5.The passage mainly tells us how to recycle rubbish.
