One morning that I was in primary school, I tried cooking for first time. As my parents weren’t in, I have to cook something to eat. I took an egg from the refrigerator, putting some oil in the pan and cracked an egg into it. After a few second, I tried to turn the egg over in case it would get burnt. Unexpectedly, it caught fire. Not known what to do, I screamed but rushed out of the kitchen. After a while, I realized I should put out the fire, so I returned back, only to find something but a black burnt egg. I’ve learned that I can’t be too carefully while cooking.

Put on new set of gasses for a new view
Today I visited San Francisco’s modern-art museum. I was there to see a new exhibit about spaceflight.1.I like to “visit” this particular painting every time I go to the museum not only because it evokes（唤起）strong feelings, but because I always find something new.
There's real pleasure to be found in revisiting a museum replaying a game or rewatching a movie. Some of that enjoyment comes from the feeling of familiarity of course.2..There’s always plenty more to see, hear, taste, smell, feel, of understand the second or third time around. But how do you discover the exciting new thing in the familiar?
One way is approaching whatever task is at hand by searching for the things that you didn't see in the first time around. First, recognize that everything is always changing.3.Second, remove judgment from the experience, if possible, and just observe what's new. For example, look for the ways in which a change in your neighborhood is interesting or exciting.
4.That could mean removing sugar, coffee, a certain kind of media from your life for a specified time. Once the break is over, that same thing will have more of its former interest or excitement.5.So is true that novelty is fun, but given enough of a break in between, repeated experiences regain that initial excitement.
A. Repeated experiences like this are valuable.
B. Visiting a new country brings fresh experience.
C. Coffee will never taste better if you quit it for a month.
D. But the piece of art that made me cry was a familiar one.
E. But it also comes from noticing new things in what is so familiar.
F. So the second experience is never exactly the same as the first one.
G. Another way is changing your routine and taking a break of some kind.
As they reach school age, about 90 percent of children will have experienced a condition in which fluid (液体) fills the middle ear, muffling (使模糊) sound and sometimes causing infection. The fluid usually clears on its own, but if not, it can lead to a painful ear infection called acute otitis (中耳炎) media. In some cases the fluid can persist for more than a year, causing hearing loss during this period, and slowing down their development of language and social skills.
Diagnosis usually requires a visit to a specialist—but researchers have now developed an app that detects this fluid just as accurately, with only a smartphone and a paper funnel (漏斗).
Doctors typically detect the problem by peering into the ear for a visual assessment. Yet, this method has only a 50 percent accuracy rate. “Right now, if you bring your child to a pediatrician, or to any urgent care family doctor, the way they look at whether or not there’s fluid in the middle ear is by looking at the eardrum,” says Sharat Raju, a surgeon in the department of head and neck surgery at the University of Washington.
For a cheaper and more accessible alternative, researchers at the University of Washington turned to smartphones. First the user follows a template to cut and tape a piece of paper into a funnel, which can be placed between a smartphone and the patient’s ear. Next the app plays a chirping sound through the phone’s speaker; the sound waves bounce off the eardrum and hit the phone’s microphone, where they register and are analyzed by the app. An eardrum with fluid behind it will vibrate (振动) differently than if the middle ear is full of air, as it normally is.
To develop the app, the researchers first played chirps for patients with and without fluid in their ears. They recorded the echoes (回音), which indicate the eardrum’s mobility. Then they used a machine learning model to classify the returning sound waves, determining which audio characteristics indicated a normal ear and which suggested the presence of fluid. Once they tested the app on 98 children, ranging from 18 months to 17 years old, at Seattle Children’s Hospital. It correctly detected fluid in 85 percent of cases, and correctly identified fluid-free ears in 82 percent.
The researchers are currently trying to get FDA approval for the app, and have founded a company to commercialize it. They hope to make it available by the end of the year, to help parents track children’s ear health at home.

4.What do the researchers expect of the app?
