【題目】A warm drink of milk before bed has long been the best choice for those wanting nights sleep. But now a study has found it really does help people nod off-if it is milked from a cow at night.

Researchers have discovered that" night milk" contains more melatonin(褪黑激素) which has been proven to help people feel sleepy and reduce anxiety.

The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.

Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

Night milk quickened the start of sleep and caused the mice to sleep longer.

While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.

Early studies have also showed that milk can be excellent for helping sleep because of containing Ca., which helps people to relax.

Milk is also sugar-free and additive-free(不含添加物的) with experts advising skimmed (脫脂的) milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

In the summer holiday following my eighteen birthday, I took driving lessons. I still remember how hard my first day was. Before getting into the car, I thought I had learned the instructor’s orders. So once I started the car, my mind goes blank, I forgot all what he had said to me. The instructor kept repeating the word, “Speed up!” “Slow down!” “Turning left!” I was so much nervous that I could hardly tell which direction was left. A few minutes late, the instructor asked me to stop the car. It was a relief and I came to a suddenly stop just in the middle the road.

At 9 pm, the ambulance brought in a man in his 60s who was having a heart attack. His face was pale, and he was frightened. The whole night I did my best to save his life. Before I left in the morning to spend Christmas with my family, I stopped by to see how he was doing. It was still tough, but he had survived the night and was sleeping.

When I approached them, the man introduced himself as Mr. Lee and said, “You probably don't remember me, but last Christmas Eve you saved my life.

【題目】The morning had been a disaster. My tooth was aching, and I’d been in an argument with a friend. Her words still hurt：“The trouble with you is that you won’t put yourself in my place. Can’t you see things from my point of view?”I shook my head stubbornly—and felt the ache in my tooth. I’d thought I could hold out till my dentist came back from holiday, but the pain was really unbearable. I started calling the dentists in the phone book, but no one could see me immediately. Finally, at about lunchtime, I got lucky.

“If you come by right now,” the receptionist said, “the dentist will fit you in.”

I took my purse and keys and rushed to my car. But suddenly I began to doubt about the dentist. What kind of dentist would be so eager to treat someone at such short notice? Why wasn’t he as busy as the others?

In the dentist’s office, I sat down and looked around. I saw nothing but the bare walls and I became even more worried. The assistant noticed my nervousness and placed her warm hand over my ice-cold one.

When I told her my fears, she laughed and said, “Don’t worry. The dentist is very good.”

“How long do I have to wait for him?” I asked impatiently.

“Come on, he is coming. Just lie down and relax, and enjoy the artwork.” The assistant said.

“The artwork? ” I was puzzled.

The chair went back, suddenly I smiled. There was a beautiful picture, right where I could enjoy it: on the ceiling. How considerate the dentist was！At that moment, I began to understand what my friend meant by her words.

What a relief！

【1】【1】Which of the following best describes the author’s feeling that morning?

A. Cheerful. B. Nervous. C. Satisfied. D. Upset.

【2】【2】What made the author begin to doubt about the dentist?

A. The dentist’s being as busy as the other dentists.

B. The dentist’s agreeing to treat her at very short notice.

C. The surroundings of the dentist’s office.

D. The laughing assistant of the dentist.

【3】【3】Why did the author suddenly smile?

A. Because the dentist came at last.

B. Because the chair went back.

C. Because she saw a picture on the ceiling.

D. Because the assistant kept comforting her.
