(2018·昆明高三适应性检测)Back home from the Navy，I started school at Greenville College in my hometown of Illinois. I’d been out of high school for four years，but my high school headmaster，Mr.Gardner，invited me to a Valentine’s Day dance party at school. The thought of seeing my former teachers was exciting. So I agreed.
When Friday came, I cleaned up，dressed up and drove to the high school gym. I chatted with my teachers and approached Mr. Gardner to thank him before leaving. Just then, the band started playing and a young girl stood up to sing. One look at her and I was crazy—I had never seen such a beautiful girl!
I asked Mr. Gardner who she was，and he answered，“That’s Marilyn Riley，Cut Riley’s daughter.”I was shocked to say the least. They lived just around the corner from me. I walked across the gym floor to introduce myself，“Hi，I’m Jack Joseph.”
“I know who you are，”was her not­too­friendly response.
“Would you like to dance？” I asked. “No！I’m working，” she shot back.
“Can I call you next week for a movie date？” I asked. “No” was her response.
For the next month I phoned，trying to set up a date. She always had the same answer：No. Then one rainy afternoon in March as I was driving home after basketball practice，I saw Marilyn, walking with no umbrella，no raincoat and no hat. I pulled alongside her and asked if she needed a ride，half expecting her to say no. Instead，she stepped over the roadside and sat down on the seat next to me. It was only a few blocks to her house，but after pulling into her driveway we talked for 45 minutes. It was magic from then on.

(2018·合肥高三质检)May Day, the first day of May, is celebrated as a spring festival in many countries. It marks the approach of summer.
The English developed their May Day festival from the Roman festival called Floralia. In the festival of Floralia, the Romans gathered flowers to honor the goddess of spring, Flora. In the Middle Ages, May Day became the favorite holiday of many English villages. People gathered flowers to decorate their homes and churches, sang spring songs and chose a king and a queen of May. Villagers danced around a tall pole fixed upright in the ground, called a maypole, each holding the end of a ribbon attached to the top of the pole. They tied the ribbons around the pole until it was covered with bright colors. They collected dew(露水)on May Day morning and washed their faces with it because they believed that the dew on the day had the magic power to regain youth.
Nowadays in Britain people no longer attach great importance to the day, but in some towns and villages people still celebrate it by choosing the May Queen and dancing around the maypole. May Queen is a girl selected as the most beautiful girl on May Day. She is usually crowned with flowers and often driven in procession through the street. In the United States, the day has never been celebrated with the same enthusiasm as in Britain. But in many American towns and cities, children celebrate the day with dancing and singing. They often gather flowers in handmade paper baskets and hang them on the doorknobs of the homes of their friends’ and neighbors’ on May Day morning. At May Day parties, children select May Queen, dance around the maypole, and sing May Day songs.

(2018·合肥高三调研)The effects of coffee consumption on health have long been a subject of conflict and uncertainty. Since the 1980s, some have spoken out against coffee as it’s harmful to health, while others have welcomed coffee for its supposed benefits to health.
According to a scientific report, mild coffee consumption, three to five cups per day, can be taken as a healthy dietary pattern, along with other healthful behavior. The report also says that coffee consumption helps reduce the risk of heart disease and it protects against Parkinson’s disease.
According to Dr. Donald Hensrud of Mayo Clinic, high consumption of coffee has health risks. Dr. Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body. Some studies said that drinking two or more cups of coffee daily can actually increase the risk of heart disease in these people.
According to conclusions from a recent study led by Dr. Gregory Marcus, a doctor from the University of California, San Francisco, daily moderate consumption of caffeine, less than 4 cups, is not associated with these issues.
Until the scientific community reaches a general agreement on the effects of coffee consumption on human health, it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks.
When informed of these possible health benefits and harm of drinking coffee, Harwood, a high school student stated, “Even though there might be some negative effects of drinking coffee, for the most part, coffee drinking sounds good for health. Not to mention I need coffee to stay awake.”　
【解题导语】　本文是一篇说明文。主要介绍了人们对咖啡是否有益于身体健康的几种不同观点。
12．What is the people’s attitude towards the effects of coffee on health according to Paragraph 1?
A．Disapproving. B．Tolerant.
C．Doubtful. D．Mixed.
D　解析：细节理解题。根据第一段可知，长期以来，饮用咖啡是否对健康有影响一直是有争议的、不确定的。一些人认为咖啡有害于健康，一些人则认为其有益于健康。D项意为“混合的，混杂的”，符合题意，故D项正确。
13．What does the underlined word “moderate” in Paragraph 4 probably mean?
A．Personal. B．Slight.
C．Reasonable. D．Heavy.
C　解析：词义猜测题。根据该句中的“less than 4 cups”可知，每天饮用的咖啡不超过4杯。据此可以判断，该句是说，每天摄入适量的咖啡因对身体无害。据此可知，画线词意为“适度的”，故C项正确。
14．What can we infer about Harwood?
A．He’ll keep on drinking coffee.
B．He loves his high school life.
C．He often falls asleep in class.
D．He has some health problems.
A　解析：推理判断题。根据文章最后两句“Even though there might be some negative effects of drinking coffee, for the most part, coffee drinking sounds good for health. Not to mention I need coffee to stay awake.”可知，Harwood认为，尽管喝咖啡可能会带来一些负面影响，但大多数情况下，喝咖啡对健康有好处；更不用说，他需要咖啡来保持清醒。据此可以推断，他将继续喝咖啡，故A项正确。
15．What would be the best title for the text?
A．Why People Love Coffee?
B．How Coffee Affects Health?
C．The Culture of Coffee Drinking
D．The New Findings of Heart Disease
B　解析：标题归纳题。通读全文内容可知，文章主要介绍了人们对咖啡是否有益于身体健康的不同说法。有人认为适量饮用咖啡有益身体健康，有人却认为过量饮用咖啡会增加心脏病的发病率。据此可知，B项最适合作为本文的标题。

(2018·长郡中学实验班选拔考试)We eat in our cars，at our desks，on the go，and in front of the TV.We eat take­out，packaged and prepared meals.Why？Because it fits our not­enough­time­in­the­day lifestyles.1.________Well，I’m certainly not the first one to think it or say it, but we all need to slow down.

While it can be a challenge to always put healthy eating first，just do your best.Remember that the food you eat has a more significant effect on your health，weight and well­being than almost any other activities you do.5.________Every meal made at home—even just once or twice a week—is a step closer to a healthier body and a slower eating style.

(2018·山师大附中模拟)Jinan is facing seriously traffic problems. Too much cars travel on the roads. This heavy traffic causes delays and the plenty of air pollution. Besides Jinan, many cities in China have traffic problems and Beijing is the worse one. One of the reason why there is so much traffic is because only a small number of people use public transportation.
In my opinion, one way to solve the traffic problems was to encourage people to make use public transportation systems. For example, people can take buses instead of drive cars. Meanwhile, the government should take measures to make them more reliable and convenient to travel by bus.

Jinan is facing traffic problems. Too cars travel on the roads. This heavy traffic causes delays and plenty of air pollution. Besides Jinan, many cities in China have traffic problems and Beijing is the one. One of the why there is so much traffic is only a small number of people use public transportation.
In my opinion, one way to solve the traffic problems to encourage people to make use public transportation systems. For example, people can take buses instead of cars. Meanwhile, the government should take measures to make more reliable and convenient to travel by bus.

Dear Tom，
Congratulations on your being admitted to Oxford University!
I’m grateful and honored to be invited to your celebration party to be held this Saturday evening.However，much to my regret，I have to decline your kind invitation. As you know, a Chinese Poetry Competition is being held in our school and I have successfully entered the final round competition，which happens to be scheduled on this Saturday and will not end until late into the evening.It’s a great pity that I can’t make it to your party.But I’ve prepared a gift for you and hopefully you will like it.
May your party be a great success and enjoy yourself that day!
Yours，
Li Hua
