China has just opened its FAST radio telescope (射电望远镜) to international scientists. It means scientists across the world can apply for using the telescope to do astronomical observations.

FAST is short for Five-hundred-meter Aperture Spherical radio Telescope. It was completed in September 2016 and it officially began operating in January 2020. Measuring 500 meters in diameter. FAST is the world’s largest single-dish radio telescope, and is 10 times more sensitive than the 100-meter Radio Telescope Effelsberg in Germany.

The major scientific task of the telescope is the observation of pulsars (脉冲星). The study of pulsars can help to confirm the existence of gravitational radiation (引力辐射) and black holes, and help solve many other major questions in physics. Another major scientific goal of FAST is to search for life outside the Earth.

The telescope is located in a naturally deep and round karst depression (喀斯特洼地) in southwest China’s Guizhou Province. The first advantage of the selected site is the altitude (海拔). The average altitude of Guizhou is about 1,100 meters. Generally, the higher the altitude, the more the telescope can observe. Secondly, the radio telescope needs to have a “big pan” to receive better signals. The huge natural depression could reduce the difficulty of construction. Moreover, the selected site in Guizhou is far away from cities, and has a low population density, which reduces the interference (干扰) caused by wireless devices such as TVs, mobile phones and radios from human activities.

So far, FAST has found over 300 pulsars. Experts predict that the number could reach 1,000 in five years and that the telescope could find and locate the first pulsar outside the Galaxy.

All of us may have experienced embarrassing moments. It could have been the time when you pronounced a simple word wrong in class, wore your T-shirt backwards, talked about someone else without realizing that they were right behind you, or secretly tried to take a picture of someone while the flash was on.

Though these embarrassing moments don’t harm us a lot, they come back from time to time and make us feel upset. Even if these moments may have faded after some time, we would always remember the feeling of strong embarrassment. In fact, these feelings may last for years. When these kinds of feelings return, they are known as a “cringe attack(羞愧综合症)”.

I personally get a quite uncomfortable feeling when I think back on a party my parents took me to when I was younger. I ate a bowl of strawberries by myself. My parents shouted at me—in front of everyone—for being so selfish. From then on, every time I put a strawberry into my mouth, my brain just throws that embarrassing scene back.

Why do these “cringe attacks” still pop up in our daily lives even though the actual events happened weeks, months, or even years ago? According to researchers, our brains give special attention to feelings that can be easily noticed. The stronger the feeling is, the stronger the memory will be. If you have a highly embarrassing or highly emotional(情绪激动的) moment, no matter what it is, your brain will try to catch it.

So how can we deal with this? Well, we can start by trying to be more objective(客观的) about our past selves. Consider that you are not alone in your embarrassment—everyone fails or makes silly, embarrassing mistakes. Instead of just trying to forget what we did, we should try to accept who we were at that moment and think about how we can change for the better.

【小题1】The underlined word “faded” has the same meaning as “________”.
A.increasedB.continuedC.returnedD.disappeared
【小题2】Why does the writer talk about his own experience in Paragraph 3?
A.To show his love for strawberries.B.To give an example of cringe attacks.

A.the more exciting life we will liveB.the shorter the event will stay in our memory
C.the better we will remember about the eventD.the more embarrassed we will feel about the event
【小题4】What’s the writer’s suggestion about dealing with embarrassing moments?
A.Taking them seriously.B.Just forgetting about them.
C.Trying to improve ourselves.D.Comparing them with others’.

A Parrot Named Marie

Then Blanchard laughed at the joke.
