More than 2.25 billion cups of coffee are drunk throughout the world each day, and it‟s likely that many taste bitter. Now, a new study suggests that coffee fans can make their drink sweeter by changing the color of their cups.
Researchers from Oxford set out to prove whether the claim that coffee drunk from a white cup tastes biter was true. They used 36 volunteers and three different colored cups---blue, white and transparent glass--- to examine the claim.
In one experiment, the white cup increased the intensity (浓度) of the coffee taste relative to the transparent cup. Then, in a second experiment, coffee drunk from the white cup was found to taste less sweet when compared to the other colored cups, while the blue cup made the coffee taste the sweetest.
The scientists believe that the color brown may be associated with bitterness, and coffee in a white cup appears the brownest.
“Our study clearly shows that the color of a cup does influence our sense of the coffee taste,” leading author Dr.
George Doorn, wrote in an article for The Conversation. “The effect of the color of the cup on the taste of the coffee reported here suggests that cafe owners should carefully consider the color of their cups,” he said. “The potential effects may spell the difference between a one-time purchase and a return customer.”
Actually, the idea that color can change the food and drink taste came out many years ago. A study published last year reported that red, strawberry-flavored cake served on a white plate was rated as 10 percent sweeter than the same food presented on a black plate.
24. The passage is mainly about _____.
A. the popularity of sweet coffee. B. an experiment made in Oxford.
C. the effect of cup color on coffee‟s taste D. useful tips on how to make coffee.
25. In which cup will coffee taste the sweetest?
A. A white cup. B. A blue cup. C. A transparent cup D. A brown cup
26. Café owners should consider their cups‟ color in order to ______.
A. reduce the daily expenses B. show their taste in coffee
C. appeal to more customers D. make their café different.
27. We learn from the passage that_____.
A. coffee in a white cup tastes sweeter than that in a transparent glass
B. over 2 billion cups of sweet coffee are drunk worldwide each year.
C. Dr. George Doorn wrote an article about making conversations.
D. the idea that color could affect the taste of drink is not new.
C
We should feel grateful in our heart when we accept anything others sacrifice for us. However, we often unconsciously do the opposite, which may not be regarded as returning kindness with ingratitude, but have the equal power to harm each other. In particular, the closer the relationship is, the more determined we are.
Jennifer, my friend Randy‟s mother, is already over 70, poor eyesight and weak legs. But due to her character, she chose to live alone in the suburbs. No matter how busily Randy works, he would go there to visit her once or twice every week.
That day as soon as he parked his car, Randy smelt the delicious smell of meat coming from her mother‟s house. His mother said, “Your birthday is coming next week, so I‟m preparing pork trotters (猪蹄) for you!” Seeing the steaming delicious trotters, he couldn‟t help complaining, “I don‟t like these things at all, so fatty.”
On his way back, he called me, saying that he felt sorry. In fact, he longed to thank his mother and eat up that bowl of trotters. But he felt sorry that it took her too much time and energy. If he didn‟t stop her strictly, he was afraid the same thing would continue. He would rather not eat trotters any more than have his mother overwork. I understand how he felt exactly. Each of us has done like that. Because of feeling sorry for others‟ sacrifice, we purposely harden our heart against accepting others‟ favor and even criticize them severely in order to frighten their goodness away and make them never do that again.【2016成都零诊考试答案】
This method may work, but it will hurt each other‟s feelings. It‟s not wrong logically, but we always neglect another sound deep in our heart: because we‟re afraid we can‟t repay them, we‟re unwilling to shoulder others‟ goodness. So we reduce its value and refuse it severely. But to destroy others‟ goodness is also to deny you.
28. Randy refuse to eat the pork trotters his mother cooked because ____.
A. he disliked them at all B. they were really very fatty.
C. they weren‟t his favorite taste D. he didn‟t want her to overwork.
29. Randy telephoned the author to _____.
A. express his apology to his mother B. complain about his mother
C. apologize for his rudeness D. ask for a bowl of trotters.
30. According to the author, we sometimes say “no” to others‟ favor so that ______.
A. they can be frightened away B. they won‟t continue doing that
C. we needn‟t repay them later D. we won‟t feel sorry for their sacrifice
31. In the last paragraph, the author implies that we should ____.
A. refuse others‟ favor immediately B. deal with others‟ favor wisely
C. repay others‟ goodness actively D. shoulder others‟ goodness completely.
D
For a while, I wrote a “Tuesday tip” on my blog Lyonsdenmom.com. It was about easy week-night dinners, organizing parties or perhaps finding time out for friends.
About a year ago, I ran out of tips.
The truth? As a busy working mom with five busy kids, I probably do have a few tips to share. But honestly, the bar is set pretty low---on a recent day when I was walking our dog, a stranger who knew I had five kids said, “Wow! You have a dog, too?! And it even looks like you showered today!” Yes, it‟s true, I shower. Not every day, but most days. See, I‟m telling the truth. Honestly, in this cold winter, I‟m probably taking a shower more to warm up than to clean up.
Other funny truths? I‟m tired. In fact, for the past year, I‟ve been too tired to type up any update on our life here in Lyons Den. It‟s hard to arrange a career with all these kids. Although folks just believe that it must be so much easier now since all the kids are in school, I‟m here to tell you, it‟s not. It‟s really not. When I get home from work, I‟m often tearfully greeted by five kids and five homework folders filled with math facts, invitations, notices and artwork.
All those happy smiling faces I share on Facebook are real. We are a happy family---thank God for that! But we‟re not always smiling, and even in those rare best times when I can get all five kids looking at the camera, the would be that one of them isn‟t wearing underwear, one is pinching (捏) someone behind the scenes and one is just perfectly pronouncing “Damn!” So, less perfectly-posed pictures, but more telling the truth. Even if only on Tuesday.
32. It seems that the author‟s life used to be _____.
A. tiring B. busy C. relaxing D. funny
33. Which of the following is true about the author?
A. She can‟t get along well with her neighbors.
B. She‟s living a happy life with her family
C. She likes to have a shower every day.
D. She has already closed her blog now.
34. Which of the following words can best take the place of the word ?
A. answers. B. chances. C. solutions D. ways.
35. The passage mainly talks about _____.
A. the happiness of a working mother B. the worry of a working mother
C. the hardship of a working mother D. the bittersweet of a working mother

People tend to become more personal and hide less of themselves when using email. Some Britain researchers have found in a recent study that there are good reasons for this.
The team of researchers asked 83 pairs of students, all strangers to each other, to solve a problem. They had to discuss this question: ___36____ The pairs of students had to talk over the problem either face to face or by computers. Dr. Johnson said, “They told their partners four times as much about themselves when they talked over the Internet as when they talked face to face. When the computers were fitted with cameras so that students could see each other, this limited the personal side of the conversation.”
___37___ It was mainly about things such as where they went to school, or where they used to live. But some students discussed their love stories, and personal childhood experiences.
Dr. Johnson believes that emailing encourages people to focus on themselves. __38__ “If you cannot see the
