These days haze(雾霾) is around us here and there. In fact, everyone has the power to change their living habits to help reduce it. Many local governments call on their people to take action to make the air cleaner.

    Transport is one of the biggest contributors(促成物) to haze. When, where, bow, why and what you drive all affect air quality. When one drives to work for one year, he uses as much energy as a bus rider uses in 10 years. So walk or ride your bicycle to work or school whenever possible. If it is necessary, you can use public transport instead of your car. Each person using public transport for a year instead of a car can save nearly a tonne of pollutants, including CO₂, from going into the atmosphere.

    Carpooling is another way to reduce carbon emissions (排放). Carpooling is the sharing of car journeys so that more than one person travels in a car. It immediately reduces your car's emissions by half.

    What you do inside your living space can have a big effect on the air quality outside it. You can do a lot of things inside and around your home that will help you pollute less and save some money.

    A large amount of our energy supply comes from burning coal, another contributor to haze. By cutting down your electricity use, you are cutting down on haze. So you may try to reduce your use of electricity by turning off lights, using your air conditioner wisely during the summer months, or updating some of your electrical appliances to low-energy models. For example, you can use energy-saving lamps that require less energy and last 10 times longer than common bulbs.

    You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies moon. For example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.

    When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.

    Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.

    Some insects, such as butterflies and ladybugs, are quite beautiful, {#blank#}1{#/blank#}did you know that many insects are also edible(可食用的)?

    Aletheia Price knows this—and a lot more about –about bugs(虫子). She also thinks that you should try {#blank#}2{#/blank#}some. If you visit the website www. eatbug.com, you will find all kinds of{#blank#}3{#/blank#} about edible insects. Most of it was {#blank#}4{#/blank#}by Aletheia Price when he was fifteen years old. Aletheia started eating bugs at the age of thirteen. Soon, she found that she really {#blank#}5{#/blank#}eating some of them. She also became interested in finding out more about which kinds of bugs could be eaten and {#blank#}6{#/blank#}to cook them.

    According to Aletheia, there are at least 1,462 kinds of edible {#blank#}7{#/blank#}. Some of her favorite dishes include mealworm, chocolate, chip, cookies and chocolate-covered crickets(蟋蟀).

    Aletheia knows eating bugs is not for {#blank#}8{#/blank#} . But if you think about it, you may feel that eating bugs is a good {#blank#}9{#/blank#}. There are millions and millions of edible bugs in this world. If you could get to used to eating {#blank#}10{#/blank#}, we would have plenty of food for everyone.

Did you know that a seed (种子) can have its own "ID card"? The "card" shows that the seed is at the national crop germplasm bank (国家作物种质库) in Beijing, known as China's seed bank.

A seed's journey to the seed bank starts with a census (普查). China's latest census of seeds started in 2021 and ended in 2023, reported CCTV News. Workers collected more than 139,000 new seeds from all over the country. They then arrived at the seed bank.

When seeds first come in, they each get a number for their "physical examination". For example, workers put all kinds of corns from different farms together. Then they put them into groups according to the seeds' look or taste.

Next, workers check the seeds to make sure they're healthy and all the unhealthy ones are given up. A worker at the seed bank showed CCTV News a seed that had a large insect (虫子) inside it, "A seed like this should not be saved," he said.

With the bad seeds gone, workers then test the good ones to see how likely they are to grow. The seed bank has a quick, smart way of doing this: Workers test the seeds and use the information they get to predict (预测) their growth. Workers dry and weigh the best seeds after several tests. Then, they're stored in fridge at -18℃.

China's seed bank keeps all the seed information safe and helps people learn about them. This can help develop new plants that can grow better and deal well with hard environments, ensuring (确保) the food safety of the country.

Now, it is easy to get vegetables from stores or supermarkets. It seems that you don't need to spend months growing them. It takes time to grow your own vegetables. However, there are good reasons to think about growing vegetables yourself.

First, you can get fresher vegetables. The vegetables you grow don't have to travel from far away and wait in stores, so they can be as fresh as possible. You might think that a pepper is a pepper, no mate r where it comes from. However, you can have a more delicious pepper when you grow it yourself.

Second, growing vegetables in the fresh air may be good for your health. Working outside in the sun can also help you get vitamin(维生素) D.

What's more, studies show that growing vegetables is good for mental (精神的) health. While you are working on the vegetables, you may forget your unhappiness and after that you may become much more relaxed.

It's good to grow your own vegetables. But the problem is that not everyone has a garden to do it. In fact, you can grow your vegetables in small cups or pots at home. So what are you waiting for? Let's get started!
