Be My Eyes

This app connects blind people in need of help with sighted people with spare time to offer through video calls.

Items posted are usually collected within an hour.

Zooniverse

Want to help with advanced global research? Zooniverse is an app with millions of registered volunteers that lets you become a citizen researcher. Help professional scientific and humanities researchers via your mobile device or the website. Global volunteers taking part in this exciting project typically don’t have a scientific background but their contribution is highly valued.

Too Good To Go

Too Good To Go is a popular American app for people who care about the environment. According to the app, 40 percent of eatable food is thrown away each year in the US alone. Users look through the pages of nearby bakeries, cafes and restaurants that have delicious food on special offer that would otherwise binned.

When Meglan Enz was 10 years old, she decorated her bedroom walls with posters, stickers, and pages torn from magazines of anything tied to the military. Then one day there was a fire in her grandparents’ house on the family farm in Hollister, California. Among the firefighters, there was a woman. Her head was covered with a helmet and self-contained breathing apparatus (设备). And she carried different tools. Enz was shocked.

“They let you do that?” the young Enz asked as the female firefighter approached. “You’re actually a firefighter?” “Yes,” she responded. “And I hope one day, you’ll think about it because we need a lot more women in the fire service.” And with that, the woman planted a seed in Enz’s young mind. Enz is now in her third season with CAL FIRE (California Department of Forestry and Fire Protection).

While the data about the number of women in CAL FIRE only dates back to 2019, they account for about 5.5 percent of the 8,300 workforce. The job is hard for everyone — male or female. Battling wildfires requires both physical and psychological (心理的) strength. Climate change has created increasingly dry conditions across California, which has led to a rise in the intensity (强度) and time of the fires spreading across the state. Fire season now runs for as long as 10 months out of the year.

When Enz thinks back to that interaction she had as a child with the female firefighter, she realizes that moment has never left her. Recently, Enz was coming off a fire line when she met a six-year-old girl, who was very excited about seeing a female firefighter. “This is so cool,” the girl said as she looked up at Enz. Enz realized she had grown into that stranger who changed the course of her own life.

4. What caused Enz to change her career goal?

A. A teacher’s guidance on her career.

B. Her interest in collecting magazines and posters.

C. Her childhood experience of fighting a fire.

D. A female firefighter’s encouraging words.

5. What can we learn from the third paragraph?

A. Wildfires are becoming more serious nowadays.

B. Female firefighters face more challenging tasks.

C. CAL FIRE has caught young firefighters’ attention.

D. California has taken effective measures to control wildfires.

6. How did Enz react when hearing the little girl’s words?

A. She was concerned about her talking to strangers.

B. She decided to change people’s attitudes to her profession.

C. She felt proud to influence others in a positive way.

D. She was eager to make more contributions to society.

7. Which of the following can best describe Enz?

A. Responsible and generous. B. Determined and inspiring.

C Considerate and sincere. D. Independent and organized.

C

When your pen is broken, the batteries (电池) in your toys run out, or you have some leftover food, what will you do with these things? You will probably throw them all into one bin. But actually, all of these pieces of rubbish need to be sorted (分类) separately.

Rubbish sorting is a big problem worldwide. In recent years, some Chinese cities have been working hard on it. Shanghai has worked with Alipay to create a “green account (账户)” service. Account owners get points by correctly sorting their rubbish. Through the Alipay app, they can exchange the points for milk, phone cards or other products. The city is asking all people living there to sort their rubbish into four groups: wet, recyclable, harmful and dry.

Wet waste is something you don’t want but that pigs can eat. Plastics, glass, paper and other things that can be reused are recyclable waste. Harmful waste includes things like medicine, batteries and bulbs. Finally, any waste that’s not wet, recyclable or harmful will go in the “dry waste” bin.

Many other Chinese cities are also sorting their rubbish in this way. For example, Shenzhen has been doing this since 2012. Students there also receive waste-sorting guidebooks that they must study. In fact, there are still many workers specially working for sorting rubbish by hand in China. There is still a long way to go. But it’s never too late for every Chinese to learn how to sort rubbish properly and protect the environment.

If you don’t sort your rubbish, all of it will go to a landfill (垃圾填埋场) and be buried together. These landfills can take up much ground that could be used for planting. The electronic waste you throw away, such as batteries or used mobile phones, can cause pollution. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.

8. Shanghai creates the “green account” service in order to ______.

A. work with the Alipay app. B. punish those who don’t sort rubbish.

C. exchange useful products. D. encourage people to sort their rubbish.

9. After drinking up the milk, you can put the milk box into a “______ waste” bin.

A. wet. B. recyclable. C. harmful. D. dry.

10. The last paragraph is mainly about ______.

A. why we should sort rubbish properly. B. where our rubbish can be dealt with.

C. how some waste can be recycled. D. what waste can cause pollution.

11. Which is NOT TRUE about rubbish sorting in China according to this passage?

A. There is still a long way to go in rubbish sorting.

B. There are many workers sorting rubbish by hand.

C. Students have to take waste-sorting classes in school.

D. Shenzhen has been doing rubbish sorting for a decade roughly.

D

Facial recognition cameras are everywhere, including in your smartphone. Many people rely on this technology to unlock their phones, open doors or make quick payments, but there is a problem: Everyone is wearing mask. What a hassle!

Now, tech companies have updated their software. Facial recognition technology can now identify people even if they are wearing a mask.

Beijing-based tech company Hanwang has announced a software which can correctly recognize 95 percent of people wearing masks, Engineering & Technology (E&T) reported. What’s the secret? It’s all about your eyes.

Marios Savvides, a professor at Carnegie Mellon University, US, studies facial recognition technology. “As we get older,” he said, “our faces change shape, but not the area around our eyes. It stays the same—even if we put on weight.”

Another company has also been working on this kind of software. Tech5 has AI that measures the shape of your face. It also scans your iris (the colored part of your eyes). Tech5 hopes to ignore all of the face below the nose.

Facial recognition software is about more than just unlocking your phone. It’s about public safety. Contact-free verification (验证) has become extremely important due to the COVID-19. More than that, facial recognition can be used to fight crime (犯罪). “It can detect crime suspects,” said Huang Lei, Hanwang’s president. Hanwang’s technology is used by police in high-security settings. This means places like government buildings, subway stations and airports. Huang admits one big weakness of this new technology: It fails when people wear both masks and sunglasses. “In this situation, all of the key facial information is lost, but I am convinced that we can overcome the weakness in the future,” said Huang.

12. What does the underlined word “hassle” in paragraph 1 mean?

A. habit. B. rule. C. trouble. D. resource.

13. What makes facial recognition software able to identify people wearing masks?

A. The forehead. B. The facial expression.

C. The shape of face. D. The eye region.

14 What is Huang Lei’s attitude towards the facial recognition software?

A. Negative. B. Favorable. C. Opposed. D. Doubtful.

15. What can be inferred about the new technology from the last paragraph?

A. There is room for improvement in it. B. It cannot store key facial information.

C. It will lose popularity in the future. D. It won’t work if people wear glasses.

Ways to help kids explore nature

Summer is the best time for kids to spend time in nature. Here are some ways to help kids explore nature in the summer holidays.

____16____ You don’t have to teach kids to love nature because they already do. Young children naturally love the outdoors and are fascinated by dirt, rocks, trees and so on.

Prepare an outdoor exploration kit (工具包). Make your nature adventure easy and safe by putting together an exploration kit in advance. Keep it in a box or a bag in your car or on your bike. ____19____ They can include hats, sunscreen, snacks, rain jackets and a water bottle.

Have a positive attitude. ____20____ Instead, consider it a welcome escape for yourself as well. Kids are the best possible excuse to get away from your desk, away from the piles of laundry and dishes, and out of the house for a few hours.

A. Clothes can be washed.

B. Start by going outside.

C. Letting the children get in touch with nature should not feel like a burden in any way.

I am a proud mother of three children, my last little one being delivered in the middle of this pandemic. She was born in August and her name is Aida.

Shortly after having Aida, my mother-in-law Ann showed me something she learned from her friend’s mother in an art class she attended weekly. She had showed me how to knit (编织) a scarf. She showed me stitches (针) and gave me her half done project.

I spent a lot of time breastfeeding my sweet little girl, so I had some extra time to do something with my hands throughout the day. I enjoyed making the scarf so I purchased tons of yarn (线) since it was winter. I wanted to make scarves for my three children as Christmas gifts.

There was a new family that moved in down the street. The only daughter of the family was Jane, a shy girl, aged 14, the same age of my oldest son David. It seemed that she came from a financially disadvantaged family, for she always wore old clothes. Worse sill, in such cold days, she had no more clothes to wear and trembled with cold.

Due to the pandemic, society was thrown into crisis mode. Schools were closed, food supplies and deliveries were suspended and children were stuck at home. In such discouraging times, however, they became good companions, talking and playing at home or around the houses.

It was dreadfully cold this winter. Every time David came back from outside, with red face, he always cried, “Mum, it is freezing outside!” Then, he came over to see whether I finished the scarf. I could tell how impatient he was to wear my scarf sooner! I had to speed the project to satisfy his expectation. But David comforted me saying he could wait a few days. What a kind and considerate boy he was ! Then my great art project finally was accomplished on the morning ahead of Christmas.

注意：

1. 续写词数应为150左右；

2. 请按如下格式在答题卡的相应位置作答。

I wrapped the scarf around David’s neck.

_______________________________________________________________________________________________________________________________________________________________________________

Later that day David came back saying Jane also deserved a scarf.

【47题答案】

【答案】  I wrapped the scarf around David’s neck. David’s face lit up with joy. Stroking the scarf softly, David excitedly kissed me in the cheek, beaming at me “Thank you, Mum. This is the best gift I have ever received.” Before I could say anything, he dashed out to join Jane with a spring in his step. I felt relieved and content as a mother, seeing David play happily outside, with the scarf sheltering him to brave the bone-chilling wind.
