Lydia runs，and picks up rubbish along the way．What she does is called "logging"，an activity combining collecting rubbish with running． Last （1） （六月） she first learned the idea of plogging on the Internet and decided to plog．
Lydia runs four or （2） （五）times a week and takes a daily walk with her two dogs．She often wears her gloves and takes several（3） （袋子） when she goes out．Sometimes she spends（4） （一半；半数）an hour collecting rubbish．She says she （5） （浪费）the last few years of her running life．Now she feels（6） （更好的） to do plogging than just running by the litter．
"It just takes a moment to stop and pick something up off the ground．（7） （然而），it makes a big difference to my community．Now my husband also（8） （加入）me，" Lydia says（9） （自豪地）．"It doesn't matter how much rubbish I pick up．It's a good way to protect our （10） （星球）．"
When I began working at Hillcrest High School three years ago， I was introduced to Sharon Dunn， the school's headmistress．
Her smart appearance and warm， friendly（1） （表情） made me like her at once． She is a small﹣boned， smiling（2） （女士）in her early fifties． She has shining blue eyes and soft（3） （银灰色的）hair． Although she dresses simply，she always manages to look nice．
She is a very fair﹣minded person who（4） （对待）everyone at the school in the same way． Even when she is upset， she is actually very calm， which is shown by her ability to（5） （克制）her feelings in the most difficult situations． Her quiet voice arid gentle，（6） （有礼貌的）manner make her popular with the children．
Ms． Dunn has no children of her （7） （自己的）， however， she says that she feels like a mother to all of the children in her school． In fact， she has no time for family life， since she gives her life to her job completely． Besides dealing with different leading（8） （任务） every day， she always takes time to talk to the teachers and parents （9） （耐心地）．
To my mind，Sharon Dunn is an educational（10） （专家）who is a wonderful role model， not only for the children but for the teachers， as well．
A group of rubbish collectors in Turkey are recycling the books that people have thrown away．They have（1） （已经）created a mobile library．There are now over 9，000 books，which are divided into 20 kinds，including （2） （医学的）care，politics，literature，history，healthy living and soon．The library is inside a （3） （卡车）that tours schools in the countryside．They hope to create a greater passion（热情）for reading books in children， （4） （尤其）in the age of mobile phones and computers．Many schools do not have a reading room or their （5） （自己的）library．
The library has got lots of attention in Turkey．People from all over Turkey are （6） （送）their old books to the library．A（7） （女士）working at the mobile library said，"The interest is growing．Each day we have guests coming here to （8） （借）books or have a quiet time to read．"The director of the library said，"We have books here for kids aged from four to （9） （十），and books for older children，like world classics and （10） （诗）．We hope that it will develop their love for books．"
Many people go to Utah because they love hiking in Bryce Canyon National Park． They enjoy （1） （岩石） climbing， camping and so on． However， some people go to Utah for a very （2） （不同的） experience．
The Boulder Outdoor Survival（生存） School（BOSS） in Utah is the world's oldest survival school． It teaches people how to stay alive without tents， or even backpacks． In Bryce Canyon， the days are very （3） （热的） and the nights are very cold． Not everyone wants to go and experience life without modern （4） （发明） like smart phones and e﹣books． Students at BOSS quickly learn that it is important to work hard and （5） （尝试） new things if they want to complete the training．
In survival camps at Boss students don' just practise camping， hiking or （6） （骑） horses． They go into the wild for days or weeks． They learn how to find （7） （新鲜的）water for drinking． They also learn how to make a fire， use a （8） （小刀） and find food to eat． Nature can often give them（9） （每件事） they need to survive．
After these people go back to the real world， they may never use these skills again． Even if they don't， at （10） （至少） they will always know that they can live without computers， electricity， and smart phones﹣even if it is only for a few days!
The Chinese high﹣speed railways have a quality all on its own． Tier I（一线） （1）c like Beijing have a couple hundred high﹣speed trains stopping at the city every day．
China's （2） （科技） on building the railway is leading the rest of the world． There is no sign that any （3） country could be better than China in near future． I had my （4）
（第一次） opportunity to ride the high﹣speed trains last week when I had a business meeting in Zhengzhou．
As someone （5）w grew up with a disdain（偏见） for public transportation（not sure why the US hates it so much）， I was afraid （6） the experience． I hoped to fly， but was told that it would be much better if I （7） （乘） the train．
The train was amazing． I had traveled on a train before in the US， and hated how （8）s it was and how many stops there were． Chinese high﹣speed trains are on a different level． The trains are clean and the seats are huge． You can't even （9） （感觉） how fast the train is moving． If there were no windows， I wouldn't be （10）a to tell when we were stopped or when we were traveling at 300 km/h﹣it is that smooth．
I'm traveling again this week by train and I'm excited．
在新的旅行启程之际，不应忘了你来自何处．
As you ，you shouldn't forget where you came from．
The thieves （偷）many things from the supermarket and were put into prison．
The sports meeting was （取消）because of the terrible weather．
It is （难以置信的）that AI has progressed in such a rapid way in the past few years．
Nowadays， the education of （安全）has caught the attention of the whole society．
Mr．Smith （亲吻）his wife and kids before he goes to work every day．
Liu Chuanjian is considered a （英雄）because he safely landed the damaged plane．
Who is （敲）at the door？
Maybe it's the postman．
I can't hear you （清楚地）． Please speak a little bit louder．
