Rachel's artwork had been accepted into an internationally famous art exhibition after she had experienced many years of rejection and lack of recognition. After receiving the news, I could hardly contain myself and decided to celebrate it with her immediately. I took my handbag quickly and raced to the garage. Then I pulled the car door open, jumped into the driver's seat, and shut the car door. I started the car and pedaled (踩踏板) to the metal. I was eager to go!
I was backing up, backing up when I heard and felt a BOOM! I looked around and realized that I didn't press the button to open the garage doors first and blew out the garage door panels (嵌板)! I jumped out of the car and felt relieved to discover that I was able to push the panels back into the garage doors so they looked normal. I covered up the scene, got back into my car, and left for Rachel's home.
That evening, my teenage son had been playing a game of solo catch to which, in the past, I wouldn't agree, for the ball made some ugly dents (凹痕) on the garage doors. But this time when he threw the ball against one of the garage doors, he didn't just dent the door—he demolished it!
He called me, "Mom, I'm so sorry. I know you told me not to play ball against the garage doors. I didn't think I would break them, though." Though I had wanted to let my son take the blame to teach him a lesson, I couldn't do it. Besides, he wasn't the only one who Iearned a lesson that day.
With the weather getting hot, bites caused by mosquitoes not only annoy people, but can result in many infectious diseases. Even when people wear long clothes, mosquitoes' complex biting methods enables them to bite some of them through.
It would be great if clothing could be used to completely prevent people from getting bitten. Researchers tested graphene (石墨烯)，a material that is incredibly thin but really strong, in order to find out if it can make clothing resistant to mosquitoes.
In the lab experiment, volunteers exposed a small patch of skin on their arm or hand to roughly 100 mosquitoes for five minutes at a time. Researchers tested three different situations: volunteers wearing no protection, wearing cheesecloth (薄莎棉布), or wearing cheesecloth plus a thin graphene layer under it. A video camera was then used to record and quantify mosquitoes' behavior, including whether they landed on the skin, how long they stayed there, and whether they began to suck blood. The number of bites each volunteer got was also calculated based on how many swellings developed on their skin afterward. Finally, researchers dropped a little water or sweat on top of the graphene layer and studied the consequence.
As a result, the number of mosquito bites on naked skin was the highest, about 16 on average; skin only protected by cheesecloth got the second, approximately 10 per five minutes' exposure. The exciting finding was that there was no swelling developing on skin covered by the thin graphene layer under cheesecloth, which means the material is effective at preventing mosquito bites. The mosquitoes landed on skin totally uncovered or covered in cheesecloth about 23 times on average, and stayed for one to two minutes. Comparatively, the mosquitoes landed on skin covered in the graphene layer fewer than10 times, and the length of their stay was much shorter. Besides, water or sweat can ruin the graphene layer, which allows mosquitoes to bite through it. But fortunately, the number of mosquito bites in either dry or wet conditions can be lowered as long as the graphene material is improved to a certain extent.
In order to help discover spoilage(变质）and reduce food waste for supermarkets and consumers, researchers have developed new low-cost, smart phone-linked, eco-friendly spoilage sensors for meat and fish packaging.
One in three UK consumers throw away food just because it reaches the use-by date(保存期），but 60% (4.2 million tonnes) of the £12.5 billion-worth of food we throw away each year is safe to eat.
The researchers, whose findings were published in ACS Sensors, say the sensors could also eventually replace the use-by date-a widely used indicator of being fresh and eatable.
The sensors cost two US cents each to make. Known as "paper-based electrical gas sensors(PEGS)", they detect spoilage gases like ammonia (a poisonous gas with a strong unpleasant smell) in meat and fish products. The information provided by the electronic nose is received by a smart phone, and then you can know whether the food is fresh and safe to eat.
The Imperial College London researchers who developed PEGS made the sensors by printing carbon electrodes(电极）onto a special type of paper. The materials are eco-friendly and harmless, so they don't damage the environment and are safe to use in food packaging. The sensors, combined with a tiny electronic system, then inform nearby mobile devices, which identify and understand the data about spoilage gases.
Lead author Dr Firat Guder, of Imperial's Department of Bioengineering, said＂Although they're designed to keep us safe, use-by dates can lead to eatable food being thrown away. They don't always reflect its actual freshness. In fact, people often get sick from foodborne diseases due to poor storage, even when an item is within its use-by date. These sensors are cheap enough so we hope to see supermarkets using them within three years. Our goal is to use PEGS in food packaging to reduce unnecessary food waste."
The authors hope that PEGS could have applications beyond food processing, like sensing chemicals in agriculture, air quality, and detecting disease markers in breath like those involved in kidney disease.
A lot of people tend to choose a balanced diet in order to keep fit, but being on a healthy diet goes beyond simply eating more fruits and vegetables. You also need to change your mindset（观念模式） about food. Take a hard look at your eating habits. Do you eat more when you feel stressed? Do you reduce your food intake on purpose in order to feel like you are in control? If your answer is "yes" , then you probably have held a problematic attitude toward food, and .
If you find that you tend to eat unhealthy foods when you're stressed, find an alternative activity. You could instead go for a walk, take a bath, or call a trusted friend for a chat. Whatever you choose, it should be something that can ease your stress.
Consider food as fuel. A lot of people believe that eating is an important way to have fun or kill time. This belief is quite common. You'd better think carefully about the exact effects the food would have on you before putting it into your mouth. Is it good for your health? Does it influence your bodily functions positively or negatively?
Get medical support from professionals. And you can't always just talk yourself into stopping destructive behaviors. If you suspect that you have an eating disorder, whether it's overeating or undereating, consult a medical specialist and get professional help.

When I was a child my father taught me five words that I've used all my life — in my acting career, as a mother, in my business activities. If I1 that I was afraid of the dark, or if I seemed worried about meeting new people, Dad would say, "Stand porter to your2 ."
A porter is a gatekeeper who stands at a door letting people in or out. Dad would get me to picture myself stopping3 things — such as fear — at the door,4 saying "Come in" to faith, love and self-assurance.
As an actress, before I went on camera, I'd make sure anxiety stayed out and confidence in my ability came in. As a mother, when I was anxious about my children, I would try not to let worry in but would5 my mind with trust in them.
Of course, there were always times I'd6 those words.
In 1972 my husband, Fillmore Crank, and I opened the doors to our own7 in North Hollywood. This was a new business venture for us, and it was a lot more8 and complex than we had9 .
We were on call 24 hours a day. Something was always going10 . Electricity went on the blink (失灵), food wasn't enough, employees called in sick. Once, a flu epidemic suddenly left us with no maids. Fillmore gave me a choice: scrub (擦洗) floors or do the laundry. For 10 days I folded enough sheets to11 the whole state of California.
Then there was the12 crisis. The price of gasoline doubled, and tourism in California13 . How could we fill our beds? What if we kept losing money? What if we failed? Fear and worry were sneaking in. But I caught them just14 I stood porter.
I stood in the door of my mind and sent fear packing.
These days at the hotel, whenever fear tries to15 , I just smile and point to the sign that reads "No Vacancy（空房）".
With time (pass) by, most of the written characters have lost in history, Chinese characters are still full of vitality. Chinese characters are (current) more than just written characters for communication or a form of traditional art we enjoy in calligraphy. They have become new eye-catching image of contemporary art. Get a load that! An exhibition, Evolution of Chinese Characters which is the (mix) of tradition and modernity, ( display). Even if you do not understand these characters mean, you can still be (fascinate) by Chinese culture.
It was a day just like every other day. I woke up early in the morning and went to run on Mount Gracious with my dog, Bubbles. As I ran up the mountain, with my dog following close behind, I felt energetic and refreshed. Running in a natural environment never failed to make me feel alive. When I reached the top, I drank some water and enjoyed the beautiful sunrise. This scene always took my breath away, no matter how many times I had seen it.
Having rested enough, Bubbles and I made our way back down the mountain. As we were running downhill, I saw an unfamiliar path and decided to explore the area. The path was full of rocks. It was not easy to walk.
Suddenly, I slipped on a muddy patch, rolling down five meters before I managed to grab hold of an exposed root of a huge tree. I was safe for now. However, I was seriously injured. My knees were badly hurt. My right foot was also dislocated (脱臼). I knew for sure I would be unable to make my way up or down the mountain without help. I called out to Bubbles and he barked loudly from above. It seemed like he understood that I needed help. He looked down at me pitifully before disappearing from sight.
As night fell, panic (恐慌) set in and scary thoughts went through my mind. There were many things that I had got to do. I couldn't die! This would not have happened if I had stuck to my usual path.
I was losing hope when I heard barking. It was Bubbles. I rubbed my eyes as I struggled to keep awake. But there was silence. Who could it be? Was I hallucinating (产生幻觉)? Then I heard some voices and more barking. Yes. Help was near, I knew. I could count on my dog to get help.

Soon, I heard my parents calling my name.
Later, my parents told me what Bubbles had done to get help.
