1 . When we pay attention, we see courage every day. I see it in my classroom when a student ________her hand and says, “I’m completely lost.” Do you know how incredibly________it is to say so when you’re pretty sure everyone else gets it?

I recently saw another________of ordinary courage in my son Charlie’s preschool. Parents were invited to________a music presentation by the kids. You know the________— twenty-five children singing with fifty-plus ________in the audience holding up cameras.

One girl cried her way through the entire________because she couldn’t see her mom. As I was telling Charlie goodbye,I saw her mom rush into the door,and immediately start ________the room for her daughter. Another mother walked by this stressed mom, shook her head and________her eyes.

Just then one more mom walked up to this now________mom and smiled. “I wasn’t just late. I________forgot.” She said, “It’s okay. We’re in the same boat.” The woman’s face________and she wiped away a tear. By the time she made it to the corner where the teacher was still________her daughter, she looked calm.

The mom who stopped and shared her story of________was practicing courage. She didn’t have to. Every time we choose________,we make the world a little kinder and braver.

3 . Tabichi’s father,uncle,and cousins have all worked as teachers. He could see that his relatives were making a real difference to people’s lives and wanted to do the same. So for the past 12 years,Tabichi has worked as a math and science teacher in the hope that his lessons will give students a chance to improve their situations.

However,working at a remote village school in Kenya hasn’t been easy. The unique challenges and obstacles have forced Tabichi to find unique solutions for his students. The school only has one computer and unreliable Internet access.The school also has no library or laboratory. To make matters worse, there are not enough books for all the students and the school is desperately in need of more teachers. Most of the students are not able to concentrate because they haven’t had enough meals at home.

One of the other major challenges that Tabichi faces is keeping kids in school as long as possible. So Tabichi spends most of his time outside of the classroom working on ways to keep kids in school. When the 36-year-old gets the feeling that a student is at risk of dropping out, he works to persuade families to put more value in education. To help those in poverty afford food,uniforms, and books, Tabichi also gives away 80 percent of his salary. Despite all the obstacles he faces,Tabichi is credited for improving the school and keeping much of the village’s youth in school. He has also managed to set up science clubs and addressed food insecurity issues.

Thanks to his tireless work, his students have excelled. In recent years,students have won national and international science competitions. In March of 2019,Tabichi was voted the best teacher in the world and won the prize of $1 million.

5 . Compared with the obvious environmental issues we hear about every day, littering often takes a backseat-but it’s more pressing than we may think.

Some may say that a banana peel out of your car along the motorway would be a harmless action. Actually, they are wrong. A banana peel can take up to two years to decompose(分解)，and with a third of motorists admitting to littering while driving, that’s a whole lot of discarded banana peels, or much worse. An orange peel and a cigarette butt has a similar biodegrading(生物降解)term to that of a banana, but tin and aluminium cans last up to 100 years, and plastic bottles last forever, so do glass bottles and plastic bags.

Despite the fact that longer-lasting materials will serve to damage the environment and its animals for longer, we can’t only measure the severity of a certain type of rubbish by its lifetime. For example, despite having a fairly short biodegrading span, more than 120 tons of cigarette-related litter is thrown away in the UK every day. Similarly, our regular littering here and there has caused the UK’s mouse population to increase by 60 million. This suddenly isn’t so mysterious when you consider that since the 1960s our annual littering has increased by an amazing 500%.

It’s not a cheap habit either: UK taxpayers spent $500 million on keeping the streets clean. So, it’s not surprising that if caught fly-tipping, you could face a $20, 000 fine. Regardless of how severe the punishment might seem, however, among the reported cases only 2, 000 were punished out of 825, 000, so we still have some way to go in making sure people observe the rules.

To take back our beautiful cities, we need to do more than simply not leaving rubbish where it ought not to be. We need to care more about the world around us.

9 . Scientists have learned a lot about the kinds of people need. They say that there are several kinds of food that people should eat every day, they are: (1) green and yellow vegetables of all kinds; (2) citrus (柑桔) fruits and tomatoes; (3) potatoes and other fruits and vegetables; (4) meat of all kinds, fish and eggs; (5) milk and foods made from milk; (6) bread or cereal (谷类), rice is also in this kind of food; (7) butter, or something like butter.

People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether foods are eaten raw or cooked, canned (罐装的) or frozen (冷冻的). It doesn’t matter if a person eats dinner at 4 o'clock in the afternoon or at eleven o'clock at night. The important thing is what you eat every day.

There are two problems, then, in feeding the large number of people on the earth. The first is to find some way to feed the world’s population so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food to make them grow to be strong and healthy.

10 . Chinese telecommunications giant Huawei officially launched the 2.0 version of its self-developed operating system (OS) on Wednesday night, the HarmonyOS. The move paved the way for the Chinese firm to challenge Google’s and Apple’s role in current and future OS ecosystems.

Among the major strong points, the HarmonyOS, with a highly scalable (可扩展的) platform, can be applied to various devices, including smart phones, computers, and other electronic devices, the company said.

Analysts said the OS will do a lot to promote Huawei’s change into being a software service provider. Huawei’s founder and CEO Ren Zhengfei said that the company was focusing on software because future development in the field was basically “out of US control and we will have greater independence and autonomy (自主权)”. Ren called on the company’s staff to “dare to lead the world” in software.

“The success of a software system will always have to rely on hardware (硬件), but nowadays, Huawei doesn’t have enough hardware to support its software ambitions   — that’s the most difficult part,” said Jiang Junmu, chief writer at a news website. Once as the world’s largest smart phone maker, Huawei’s national smart phone market share (份额) has continued to drop in recent months. Liang Zhenpeng, an industry analyst, said that as an OS designed for the Internet of Things(IoT) era, the HarmonyOS may need more time and equipment to test than the OS for smart phones, and that will take at least two to three years.

Moreover, Liang noted that an ecosystem will always be the decisive factor for the success of an operating system. “Does the HarmonyOS have enough applications that can attract consumers to update to the OS? That’s a question,” Liang said. So far, more than 300 application and service partners, 1000 hardware partners, and 500,000 developers have joined in the set-up of the Harmony ecosystem.
