You can be proud of yourselves, even if you can only make one or two of these green changes. The goal here is to limit carbon dioxide and other greenhouse gases, which are closely connected to the big problem of global-warming (全球变暖).

    WAY 1: Bring your own cup to Starbucks. You'll get a 10-cent discount, and it's one less paper cup to end up in a dustbin. The store won't create more waste when they throw away a cup.

    WAY 2: Turn off your computer. When in standby mode, your PC is still using energy. Turning off a monitor (显示器) for 40 hours a week may only save $ 5 a month, but it reduces CO₂ by 750 pounds.

    WAY 3: Reuse plastic bags. Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag. The amount of oil it would take to make just 14 plastic bags would run your car for one mile.

    WAY 4: Use recycled paper in the bathroom. Most of the toilet paper we use is made from trees found in forests. If every family replaced(替换)one roll of toilet paper with a recycled one, 424,000 trees would still be standing.

    WAY 5: Plant a tree. Adding green to your garden is beautiful and earth-pleasing. Just one tree will help make cleaner air and save the environment from 5, 000 pounds of hot carbon dioxide each year.

Everyone wants to be successful, but failure (失败) is a common thing for us to meet with.1, sometimes we fail the exams; sometimes in the sports meeting, others2 but we fail. So almost3 meets with the failure in his life.

However, different people have different4 to deal with(处理)the failure. Some people lose hope when they fail. They seem to think that it is the5 of the world. But others don't take failure6. They seem to think that failure is the first step(步骤)to success. They will7 and try their best to get the final success.

Now let's imagine( 猜想)the ends of the two ways. If we are afraid of the failure and always feel sad, and don't try our best to change ourselves, we may meet with more and more failures. But as8 as we are hopeful and brave to face the failure, and never give up, we will become9 and our dreams will come true some day.

So, please remember: Life doesn't give us the pleasure we want. But if we never give up and10do little by little, it will make a big difference.

Researchers have developed a printer that produces 3D personalized chocolate. The printer, which produces 3D chocolate by b{#blank#}1{#/blank#} up successive layer is thought to be an improvement in gift shopping. It has already received huge amounts of interest from shopkeepers. 

It is hoped that project will eventually see people designing and creating their own products across a wide range of gifts. The l{#blank#}2{#/blank#} researcher, Dr. Liang said, "What makes this technology special is that users will be able to design and make t{#blank#}3{#/blank#} own products. "In the long term it could be developed to help consumers. design many products from different m{#blank#}4{#/blank#}" From the shape of a child's favourite toy to a friends' face, the possibilities are endless and only limited by our ideas, " he said. 

The research team is now looking to develop a consumer stage where people will be able to send their own chocolate designs for 3D printing. They will also be able to browse through the designs of other users, but can't c{#blank#}5{#/blank#} them without permission. Dr. Liang added, "Eventually we can may see many mass-produced products being r{#blank#}6{#/blank#} by unique designs created by customers. "

This is an imaginative application of two developing technologies as well as a good example of how creative research can be applied to create new products and sales-ideas. 

He also said, "By combining developments in engineering with the commercial potential of the digital economy, we can have a look at the future of new markets—creating new jobs and, in this case, sweet business opportunities. 

Hello，I'm Jack. This is1 family. These2 my grandparents. They are 80. Their hair（头发） is3 . This is my father Steve and this is my mother Mary. Look！4 is my mother's jacket？It's red. It's5 . This is my aunt（姑姑） Anna. She is my father's6 . This is my7 Dan. He is Anna's husband（丈夫）. They have8 children（孩子），Tom and Alice. 9 boy in blue is me. I'm in No. 6 Middle School. Alice10 in my school. She is in No. 9 Middle School. 

In Beijing, along the famous Chang' an Street, a lot of bikers ride very expensive bikes. It is said that bikes are priced at between 1,000 yuan and 100,000 yuan. Bike riding becomes popular among people in some big Chinese cities.

Li Ming, who worked as a sales manager at Specialized before, said that people became interested in having a bike especially in China's big cities. He added that now many people could accept high prices for premium(高端的) bikes.

As the two Olympic Games were held in our country, the government started to pay more attention to sports. People began to realize the importance of having a healthy body. It's said that the popularity of bike riding is related(相关的) to the COVID-19 epidemic, people's higher living standards and people's awareness(意识) of the importance of a healthy lifestyle.

At the same time, more and more bike lanes(自行车道) are built in some big cities. People's need for a lot of bikes is a big chance for bike makers. Some best selling road bike s are always sold out quickly.
