A patient recently had the procedure done for an inherited form of blindness. The operation took place at Oregon Health and Science University in Portland. “We literally have the potential to treat people who are essentially blind and make them see,” said Charles Albright. He is chief scientific officer at Editas Medicine in Cambridge, Massachusetts. Editas is one of the companies developing the treatment. Albright added, “We think it could open up a whole new set of medicines to go in and change your DNA.”

The people taking part in the study have a genetic condition that keeps the body from making a protein needed to turn light into signals to the brain, which leads to sight.

Scientists have found it difficult to treat the condition with usual gene therapy. So, they are aiming to edit or remove the mutation（突变）by making two cuts on either side of it. The hope is that the ends of DNA will reconnect and make the gene work as it should. Through a tube the width of a human hair, doctors put three drops of fluid containing the gene editing machinery just under the retina（视网膜）, which is the lining at the back of the eye that contains the light-sensing cells. Doctors believe they need to fix one-tenth to one-third of the cells to repair vision. In animal tests, scientists were able to correct half of the cells with the treatment, Albright said.

Some independent experts were hopeful about the new study. Dr. Kiran Musunuru is a gene-editing expert at the University of Pennsylvania. He said the treatment seems likely to work, based on tests in mice and monkeys. The gene editing tool stays in the eye and does not travel to other parts of the body. So, “If something goes wrong, the chance of harm is very small.” Musunuru said. “It makes for a good first step for doing gene editing in the body.”

Inside the walls where you live or study, there are big wires that carry electricity. When you plug in a light or radio or other electrical appliance, you are putting the light or radio in the path way of the electricity. You have heard adults warn, “ 【2】，‘ Now do you know why? If you did, you would become part of the electrical path way.

【3】 The electrical current coming through the wires to the wall plug is so strong that it would hurt a lot if you stuck your finger in the plug. Put your finger in there and it could be you, rather than the light bulb, that becomes part of the electrical path way. And that would hurt!

What if you held a piece of metal, like a fork or knife, and stuck it into the wall plug? Don't do it. Why? It's because metals also conduct electricity. 【4】

Don't touch any electrical appliance when you are wet. Can you think why? It's because water is a good conductor of electricity. When your hands are wet or when your body is in a bathtub full of water, the electricity could flow right through you and give you an awful shock, or even kill you.

Electricity is very useful, but it can be dangerous. 【5】If so, electricity can better serve you, instead of hurting you.

As for me, I had been fired earlier in the day. I was prepared for it as I had experienced the same thing 14 years earlier, but, just like a punch in the mouth, the blow is never softened because you were expecting it.

As I watched the adversity on the court that my son was experiencing, I recalled my earlier events, packing up everything in a box and waving goodbye to a great group of colleagues with whom I’d had the pleasure of working. During my driving home, I kept telling myself “Just like that time, I will find work again in a short time—I am confident in my experience and abilities.” It was the same belief that I tried to teach my son.

The basketball game entered the fourth quarter with Nathan’s team still trailing. As Nathan and his teammates fought back, I saw the focus and determination on him, as well as his teammates’faces. Then, with a tie game and seconds on the clock, Nathan found himself with the ball. There was no room for self-doubt. With skill and confidence he was able to tune out all that could drive his attention away and make the throw as if he had done it a thousand times. The joy on his face, the cheering from the crowd, and the silence on the other side of the gym—it was a moment that would make any parent proud.

As I sat there, my heart bursting with pride, it dawned on me that I had taught him determination in the face of adversity, and he had just taught me the same lesson. That brief moment of self-doubt and feeling sorry for myself was blown away by the actions of my son on the basketball court. He will play in the finals, but it doesn’t matter if he wins or loses, at this moment.

To whom it may concern,

I am one of your customer. I am unwilling to complain, and your service really annoys me. I order a set of Bookworm Series on your website the other day, but not until yesterday I receive it. Much to my disappointment, the books were so poorly packed up that the cover of one book was torn. To make matters bad, it was not a complete set, as I found one book missed.

I am sorry to have received such poor service. I believe I have every right to ask you to deal with a problem. I hope that you either return my money back or deliver a new set of books to me. Therefore, I’d like to be informed of the process of your dealing with my complain.

Looking forward to your reply.

Sincerely,

Wang Ling
