I still remember my first time going to the Chinese company's canteen. When I stepped onto the elevator, each one was full of people. 1. However, there was no sign of fire and people were laughing and talking. I followed the flow of the crowd to the doors of the canteen. It occurred to me that in China everyone has lunch almost at the same time. 2.The canteen followed this schedule, only being open a few hours per day.
When I stood in the doorway, I realized I had to act fast or I would be left behind. 3. Unlike my school lunchroom, here everyone lined up and took a tray, and instead of silverware there were chopsticks and soup spoons.
As I was pushed along the line, I saw dishes I didn't recognize and as people cut in line and picked up dishes left and right, 4. I ended up taking a pork and cucumber dish and a tofu salad.
I have been at my company for over a year and a half. 5. I have learned what dishes I like, mostly by trial and error, and a lot of the workers know me and say hello to me.
I am still getting used to eating lunch at "lunchtime", but I think the schedule definitely helps keep me on track during the day. I wish there were something like this at offices in my hometown.
A.I thought I had missed a fire drill.
B.There was no emergency; it was just lunchtime.
C.I noticed things at lunchtime were a bit different.
D.I felt that I needed to make some quick decisions.
E.The canteen reminded me of my school lunchroom.
F.And now I am glad to say I am more confident in the canteen.
G.I was not very familiar with the local food or restaurants in China.
Music is not just a set of sounds and rhythms. Its influence on the brain is much deeper than any other human experience. Keep on reading to know all those amazing powers of music.
A recent study suggests that preterm (早产的) babies appear to experience less pain and feed more when listening to music. Experts led by Dr. Manoj Kumar of the University of Alberta, Canada, found that music had a beneficial effect on reducing pain for preterm babies experiencing painful medical tests. It also appeared to benefit full-term babies during operations.
Many people experiencing brain damage have speech and movement-related problems. Music can help recover from brain injuries. As a different and effective treatment, doctors often advise such patients to listen to good music to improve the parts of the brain responsible for these two functions. When people with neurological (神经的) disorders hear a musical beat, it helps them to regain a balanced walk.
Though music cannot make deafness disappear, it really can stave off the loss of hearing. There was an experiment involving 163 people where 74 were musicians. Participants were asked to pass some listening tests. Musicians heard the sounds better than non-musicians, and this difference gets clearer with age. This means that a 70-year-old musician hears better than a 50-year-old non-musician, even in a noisy environment.
Besides, music mends a broken heart. It is not about a thrown-away love, but about a heart attack. The matter is that music can help people recover from a heart attack or heart operation by reducing blood pressure, slowing down the heartbeat rate, and reducing anxiety. Listening to the quality music produces positive emotions, improves the movement of blood, and expands blood vessels, thus, promoting quick recovery of the whole cardiovascular (心血管的) system.

A.It helps reduce their pain.
B.It helps develop their potential in music.

2.What does the underlined phrase “stave off” in Paragraph 4 mean?

3.Why can music mend a broken heart?
A.It has a positive effect on human body systems’ work.
B.It can help people prevent diseases caused by anxiety.
C.It helps make a person feel optimistic about life.
D.It can help patients recover in a slow way.
4.What may be the best title for the text?
A.Who can benefit from music
B.The best time to listen to music
C.The way to choose quality music
D.How music affects our mind and body
When baby turtles first come out of eggs, they head to the sea by nature. The beach surface goes down, which is one directional clue they follow. Another is light: The horizon (地平线) over the sea is brighter than the horizon over land.
But lights from towns and beach developments can confuse the baby turtles. The sky shining above a city can mislead them to wander. And particularly bright lights can draw them away from the sea.
You’d think the extra time crawling (爬行) might wear out baby turtles, which need energy once they get in the water to swim for about a day to get to their destination in the sea. In a normal trip from nests to waves, the babies build up chemicals that show they have been pushing themselves.
Some researchers took the baby turtles to a lab, where they ran on a treadmill and swam in a tank while their blood and breathing were monitored. The finding is surprising: even after hours of crawling, the turtles were fine by all measures and swam as well as turtles that didn't have an extra crawling period.
The reason is that they often stop while crawling if they are doing U for a long time, unlike the disturbed trip they make when heading straight to the water. So misled turtles are not worn out.
But the misleading lights are still a problem for the babies. The longer they spend on the beach wandering, the more they are exposed to natural enemies. They can also end up losing their lives in the heat of the sun.
1.What attracts the baby turtles away from the sea?
A.Bright lights. B.Vast beaches.
C.Buildings in cities. D.Noises from towns.
2.What does the underlined word “they” refer to in paragraph 3?
A.Chemicals. B.Nests.
C.Waves. D.Baby turtles.
3.Why don’t the baby turtles feel exhausted after long crawling?
A.They travel by night. B.Their trip is undisturbed.
C.They take frequent breaks. D.They are refreshed by city lights.
4.What may happen to the baby turtles exposed to misleading lights?
A.They are in great danger.
B.They avoid their natural enemies.
C.They will wander on the beach for a while.
D.They are more likely to find the destination.
