Most of us like to know where we are and where we’re going. It can feel strange to be ________. The words “being lost” make us think of a dark and scary wood or street, ________ that’s not always the case.

Once we were on holiday in Venice. My dad planned to go out to take photos early the next morning. Mum wasn’t ________, but I would go with him, only because he ________ I could have the biggest ever bowl of Italian ice cream if I did. ________ else could make me get up so early?!

So at 5 a.m. the next day we left the hotel and started walking in the ________ streets. When the sun came up, Dad started taking photos and I ________ him, down small streets and over little bridges.

After about an hour, I turned to Dad and asked, “Where are we?” He said, “I have no idea.” I immediately felt a bit ________, but Dad just laughed and said, “We’re lost!” I told him to ________ his map or phone. He said, “I only brought the ________. Come on, let’s get more lost!” He laughed again.

His laughter ________ me and made me feel safe. Slowly people were appearing on the streets—shops and cafes began to open.

I began to ________ that we were lost, and just started watching and enjoying everything that was happening around me.

After about four hours of walking around, we wanted to ________ for our hotel. Finally, we were back. Mum asked anxiously, “Where have you been?” I said with a big ________, “We got lost!”

These days we ________ get lost with so many things around us—maps, GPS, apps on our phones, and so on. But Dad showed me that being lost can sometimes simply be something to enjoy.

Have you seen this meme (表情包) online before? The man in the meme is Michael Rosen, a famous British children’s book writer who has written about 140 books. He’s known as “nice granddad” in China.

Michael Rosen was born in Middlesex, the UK in 1946. His parents were both teachers. Michael Rosen started writing poems about people he knew when he was twelve years old. Michael Rosen was busy with the teaching of writing and the reading of literature (文学作品) in schools. He visited schools to encourage children with his love for books and poems. He was one of the first poets to make visits to schools around the UK and the world. He is also one of the first poets to write about his own childhood experiences and to write them in the language children actually use.

However, life hasn’t always treated Rosen well. Eddie, his second son, died at the age of 18. Rosen couldn’t forget how he felt. The death of his son was the inspiration for Michael Rosen’ Sad Book. In March 2020, Rosen was sent to the hospital because of COVID-19. Later, Rosen recovered and went back home, but one of his ears went deaf and he had to learn how to stand up again, just like a kid.

However, for Rosen, it was not the end of the world. He turned the sad experience into writing. He wrote the book Many Different Kinds of Love and faced up to life with the most important thing—optimistic (乐观的) spirit.

Driving coaches might soon be replaced (代替) by AI in the near future. A company in China has developed an AI-powered driving coach called Robo Coach, and it’s already being used in some driving schools.

Robo Coach is not a human-like robot that sits next to you and complains (抱怨) about your driving skills. The AI driving coach developed by Beijing Yi Jia Jia Technology is actually a teaching and safety control system. The other ways in which Robo Coach are different from human driving coaches are even funnier, though. Robo Coach will call you “mommy” or “daddy”.

Robo Coach has more than 40 different sensors (传感器) on the car to notice people, other cars and roads. Robo Coach uses sensors to stop if the car runs into something or increases speed suddenly for no reason, similar to how self-driving cars work.

It communicates with learners and helps decision making and instructions. And to make faster decisions, the car is also provided with radar (雷达) systems. The system isn’t just keeping new drivers from meeting accidents. It also collects information on their driving behaviors and even body positions. It studies these driving habits in real time to see if the learner is too traditional or easy to be angry during practice and then changes its teaching style. By recording all the problems a learner runs into during lessons, the system tries to help the new driver correct past mistakes and prevent new ones.

Robo Coach is now being used in 5 driving schools owned by Yi Jia Jia Technology as well as 22 other driving schools across China.

In the past, green used to be simply a color. Now it means much more! In the 1970s, some people began to worry about what we did to the Earth.     46     It is a big idea that touches governments all over the world, and a small idea that touches us all in our homes.

Architects (建筑师) and building engineers are thinking about how to make buildings greener. These days, green building is becoming more and more popular. What is a green building?     47    

Firstly, we need to be very careful about the materials we use. It is better to choose renewable (可再生的) materials that the Earth replaces quickly or we can reuse some materials.     48     Our Earth has offered us many other possibilities, like solar power (太阳能).

Secondly, planners must think about the needs of those who will spend time in green buildings. In many cases, green energy is more comfortable for people.     49     Natural lighting is often kinder to the eyes than electric lighting. In fact, many people who live or work in green buildings feel happier and healthier.

    50     For example, they might try to use as little land as possible. If a building covers a large area, there will be less space for plants and trees. They also have to think about cutting down waste and pollution while the building work is going on.

Although green buildings are more expensive to build, they are less expensive to run.

Qingming, meaning clear and bright, is an important festival in spring. It’s also     56     (call) Tomb Sweeping Festival. It     57     in early April. On that day, people visit the tombs (坟墓) to honor the dead. They always spend some time     58     (clean) the tomb areas. They usually plant some trees near the tombs     59     put some fresh flowers around to make them more beautiful.

But it is not only a day for honoring the dead but also a good time to welcome spring. With the coming of spring, the nature wakes     60    , dressing the world in green. All around the world is new, clean and fresh. Birds begin to fly back     61     the south happily to build homes for their babies. In the forests and fields, many animals come out of     62     (they) holes and have babies at this time of a year. Days begin to get     63     (long) and the weather gets warmer.

Qingming is a happy time for people to enjoy outdoor     64     (activity), such as flying kites and hiking. That is the reason     65     this festival has been very popular for thousands of years.
