When your doctor asks how often you exercise, do you give her an honest answer? How about when she asks what you’ve been eating lately? If you’ve ever stretched (夸大) the truth, you’re not alone.

Sixty to eighty percent of people surveyed have not told their doctors about some information that could be relevant (相關(guān)的) to their health, according to a new study. Besides fibbing (小謊) about diet and exercise, more than a third of respondents (受訪者) didn’t speak up when they disagreed with their doctor’s suggestions. More often than not, they fail to admit they didn’t understand their doctor’s instructions.

When respondents explained why they weren’t transparent (坦誠(chéng)直言的), most said that they wanted to avoid being judged, and didn’t want to be lectured about how bad certain behaviors were. More than half were simply too embarrassed to tell the truth. Most people want their doctor to think highly of them, says the study’s senior author Angela Fagerlin, Ph. D.. “They re worried about being thought as someone who doesn’t make good decisions,” she adds.

Scientists at University of Utah led the research study together with colleagues at University of Michigan and University of Iowa. The results will be published online in JAMA Network Open on November 30, 2018.

Insights (深入了解; 洞察) into the doctor- patient relationship came from a national online survey of two populations. One survey got responses from 2,011 participants (參加者) who averaged 36 years old. The second included 2,499 participants who were 61 on average.

“I’m surprised that such a large number of people chose to withhold (隱瞞) relatively benign (相對(duì)無(wú)害) information, and that they would admit to it, says the study’s first author Andrea Gurmankin Levy, Ph. D.. The trouble with a patient’s dishonesty is that doctors can’t offer accurate medical advice when they don’t have all the facts. “If patients are withholding information about what they’re eating, or whether they are taking their medication, it can have influences for their health, especially if they have a chronic (慢性的) illness,” says Levy.

1.What can be inferred from the passage?

A. Patients always lie to their doctors.

B. 60 to 80 percent of the patients can’t understand their doctor’s instructions.

C. Most respondents disliked being judge.

D. Fibbing can’t have bad influences for patients’ health.

2.What does the underlined word it in the last paragraph refer to?

A. Relatively benign information.

B. Withholding relatively benign information.

C. A large number of people chose to withhold relatively benign information.

D. The trouble with a patient’s dishonesty.

3.Which of the following statements is NOT true?

A. There were 3 universities doing the research study together.

B. Over a third of respondents didn’t show their disagreement with their doctor’s suggestions.

C. Some patients often choose to tell fibs when facing doctors.

D. Levy believed most people want their doctor to think highly of them.

4.What is the meaning of the word “accurate” in the last paragraph?

A. professional B. effective C. available D. exact

Born as the only child in the family, I am the “king” of the family. My parents are both businessmen and they come home every two weeks. Because they don't spend much time with me，they always feel guilty (內(nèi)疚的) and will buy me many expensive things and let me do whatever I want. My grandparents never let me do any chores because they want me to do my schoolwork.

I used to take everything for granted (理所當(dāng)然) and I never said “thank you” to people. As time went by，I found that my classmates didn't like me and my best friends left me. One day，I asked Leo, who used to be one of my best friends. He said that I was mean (自私的)，rude and bad-tempered (壞脾氣)．“No one wants to make friends with a person who always receives but never gives anything！”he said. I was shocked at his words. “Oh，no! Please don't leave. I need friends! I will be lonely and unhappy without friends！” I locked myself up in the room and cried. “I want my friends back. But how？”

Then I noticed that all the popular kids in the class are friendly to others. They always smile and say “thank you” to others. They do whatever they can to help when others are in trouble. Other kids like them and always play with them. “I need to change! I will get my friends back,” I said to myself. From then on，I started to change myself. I learned to say “thank you” to others，I smiled and volunteered to help other kids. I tried to be as nice as I could. Gradually, I found that other kids liked to talk with me and they would ask me to play with them and even told me their secrets. My friends came back to me again.

Now I have more friends than I used to have and I am happier than I used to be.
