Physic book or e-book |

William April 16, 2020 | I'm a book addict (书迷). I have loved reading books—I mean physic books, ever since I learned how to do it, I read them while eating, on the bus, and even in the bath! As an adult, I have just graduated with a degree in English Literature, so I have spent the recent three years doing even more reading than usual! |
| Lenara Dec. 12, 2019 | I have lots of books. My room is full of books, not only my childhood favorites but also those I haven't even read yet. When I decided to move to Spain to work as Language assistant, I faced a big problem. I had only one suitcase for a ten-month stay, so I had to pack lightly. It would be impossible to pack enough physical books for nearly a whole year. My only choice was e-books. |
| Amelia Dec. 23, 2019 | I agree with my friend, physical books are better than e-books. But a big problem is about the cost of physical books. And another problem, we have to cut a lot of trees to produce paper. |
| Gianggi Sept. 9, 2019 | I have always been hating e-readers! I even wrote an article about it when I was at school. I love physical books so much. Compared with physical books, e-books seemed emotionless (无情感的). But while traveling, my choice was e-books or no books, so my brother bought me an Amazon Kindle for my birthday. Now I am on my sixth e-book, and I'm starting to love my Kindle! The e-reader means I never have to worry about there's nothing to read. Yes, there is something I hate, but in general it has become one of the most important parts in my life! |
You have been told to wash your hands many time a day to help stop the spread of the new coronavirus (新冠病毒). But what about the mobile phone that you're always using? Scientific studies have shown that the virus can live for two to three days on smooth materials like plastic and stainless steel. Experts suggest cleaning all "high touch" surfaces every day, including phones, keyboards and computers. However, few people know how to do the cleaning. Here are some things not to do when cleaning the phone.
◆Do not spray (喷) cleaners directly on the phone.
◆Do not put the phone into any cleaning liquids (液体).
◆Do not use tools that use forced air, which are often used to clean computer keyboards.
◆Do not clean the phone with hard materials, they could make small cuts on it.
So, what is the right way? Below are some suggested ways to clean the phone. With any of these suggestions, be sure not to get the phone wet.
◆Start by turning off the phone. Make sure the phone is not connected to the electricity.
◆Use cleaning cloths with 70 percent alcohol (酒精)instead of the common ones.
◆Use paper cloths, or other soft cloths like those use to clean the eyeglasses. It's OK to cover the cloths lightly in cleaners. But do remember to clean the phone"gently".
Cleaning the phone is one of the measures that are helpful to keep away from the new coronavirus. You should clean your own phone often and tell others the correct ways to do it.
One day, Anna Du was walking along Castle Island's beach. She found there were lots of plastic pieces in the sea and some were too small to pick up. She began to think about how to solve the problem.
First, she did a survey. The result showed there were already 150 million tons of plastic in the sea, and every year there would be another 8 million tons. She realized something must be done. So she decided to invent a robot that could work under water. She tried again and again. At last her ROV came out. It could move through water and pick up plastic pieces, especially the tiny ones.
With this ROV, Anna Du took part in the Broadcom Masters competition which is one of the top STEM competitions. It's for young students around the world. This year, more than 5, 000 students were interested in the competition, but only a few got the chance. Anna Du's ROV caught a lot of attention. It had a camera with three different kinds of lights which could find plastic pieces easily. Dana Yoerger, an expert, said, "The ROV is nicely done for a 12-year-old girl. It's very clever."
In fact, Anna Du is always learning to solve the world problems and her parents are always supporting her. At the age of five, she began to go to workshops to learn engineering skills. When she was asked about the future plan, she said, "I want to be an engineer because I like building things. I think many world problems can be solved with new inventions. Right now, I'm just caring about plastic problems because there is still a long way to go. "
a. Anna Du invented her ROV.
b. Anna Du walked along Castle Island's beach.
c. Anna Du began to learn engineering skills in workshops.
d. Anna Du took part in the Broadcom Masters competition.

Today is a big day for me. The last time I spoke in class was three years ago and it was1I tried to say /w/, but made a strange sound. Everyone laughed. I haven't spoken in class since then.
2, things have been changing a lot. Now when I listen to music on my headphone, I can follow without stuttering (结巴)!That's why I 3 to talk at the science festival today.
I arrived at school early. Ryan Colby, who enjoyed 4 at me, was standing by the entrance. He said, "Hey, Tom, guess what? "I tried to say, "What?" but got stuck on the /w/. He started laughing. I turned and ran.
I wasn't going to show up at the festival, but on my phone I got a 5from Dad, saying "good luck. And I thought OK, I wouldn't let people like Ryan Colby make me feel bad any more.
When it was my 6to speak, I just saw Ryan Colby. And then I was so 7that I chose the wrong music. So instead of Mozart, I was listening to dance music, I couldn't 8myself talking in the same rhythm (节奏) as the music. It sounded like I was rapping (说唱). Most people in school never heard me speak. They were really surprised. When I finished, they all stood up and cheered.
After the festival, 9 wanted to be my friend. They thought I was a talented and skillful rapper! I 10 my phone at lunchtime and found 187 new friend requests. And one of them was from Ryan Colby.
It's not usual that you can feel the warmth in an icy train station. After all, it's the place where people walk (quick) from one end to the other for their trains with impatience. However, just there, a cold Friday morning, I saw something that moved me to tears.
While I (walk)to the hall of the station, I saw a young woman put something next to sleeping homeless man. She put it down silently and left in a hurry. I wondered , she had put some money there. Instead, it was a sandwich (lie) on the man's bag. I suddenly realized that a sandwich was probably what the man needed most.
I couldn't help thinking of many times when I (help) by others. I also thought about that all the other little acts of (kind) that happened every day and went unnoticed. Even the smallest thing can make a big (different). And what a gift it is when you get to see the (move) moments!
Many students want to improve their memories and learn better. Today we will introduce some no-cost things you can do.
Exercise
Before you study, doing exercise may help you better remember what you will learn. Recently, researchers have found that people who did 15 minutes of training remembered more words. Scientists say the best time to exercise is right before you study. It can make you more active.
Pre-study test
The students who take a test before studying remember more information than those who don't. For example, if you are using an English textbook, you might first look at some important words at the end of the unit. You could ask yourself what they mean or how they are used. While you might not know the answer, you will probably have a goal to learn so that you can remember the answer when studying!
Sleep
A study show that sleep helps you to learn in two ways. An expert explains that" a person with enough can concentrate best" He also says, "Sleep itself plays an important role in making the memory stronger which is necessary for learning new information.
Wakeful rest
When you finish studying, you often go straight another activity. Perhaps you play a video game watch TV. But researchers suggest that resting after you study may help you remember what you've studied. In a study, even older adults who rested for 10 minute after learning new words remember more words better.
