Imagine your body is like the house you live in. Every day, your family creates rubbish. The rubbish builds up until it is put out for the weekly garbage collection.
Now, say you put three bags of garbage out, but because one of the collectors was away sick, only two bags are collected. You take the leftover bag inside to be put out again next week. The following week you put on another three bags, plus the leftover bag from last week. But again, only two bags are collected. Imagine this cycle is repeated over the following weeks.
This is a simple description of what happens to your body when your kidneys (肾脏) don’t work efficiently. Your body is not thoroughly emptied of waste products. Other areas of the body such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins.
It’s not uncommon for people to lose up to 90% of their kidney function before developing any symptoms. There may be no warning signs. This makes early detection (诊查) difficult.
Kidney’s main job is to remove toxins (毒素) and unwanted water from our blood. Every day our kidneys clean an average of 200 litres of blood. Kidney failure may be a gradual and silent process, going unnoticed because there is no apparent pain.
Research shows that more than 25% of the patients requiring dialysis (透析) do not see a kidney specialist before they have to do so. Some risk factors for kidney disease such as age and genetic make up are out of our control; however, some changes in lifestyle may help prevent kidney damage．Two major risk factors for kidney disease, diabetes (糖尿病) and high blood pressure, have been on the rise over the last few decades．Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential risk factors for the kidney disease.
1. The author gives the example of the house we live in to indicate that _______.
A. it’s safe and harmless for our body to keep some waste
B. it’s important for our body to empty the waste in time every day
C. our body will not produce any waste if our kidneys work efficiently
D. it doesn’t matter much if the waste in our body is not emptied in time
2.The underlined word “insidious” in the third paragraph means _______.
A. smooth and safe B. obvious and fast
C. gradual and unnoticed D. long and painful
3.We can infer that when we find some symptoms related to our kidneys, _______.
A. the kidney failure begins
B. the kidneys can still work properly
C. we have lost about 10% of kidney function
D. the kidneys may have been seriously damaged
4. Which of the following helps prevent kidney damage most effectively?
A. Go to see a kidney specialist shortly before dialysis starts.
B. Take enough exercise and make early detection of kidney disease.
C. Try to keep low blood pressure and a stable lifestyle.
D. Go to hospital whenever you find any warning signs.

“Chances are we have all experienced shyness in our lives, and shyness has been associated with negative outcomes—characteristics like difficulty maintaining eye contact, and feelings of humiliation(丢脸) are known to be part of a shy person’s characters. It’s these traits that tend to affect some shy individuals’ ability to connect,” says C. Barr Taylor, a professor of psychology at Stanford University.
“But while shyness can often be seen as a bad thing, there are ways to use the personality trait to your advantage,” Taylor says. Below are some common shy habits and how you can learn to make them benefit you:
Shy people usually reflect inwardly (在内心) a lot. But according to Taylor,all that thinking may not always be a bad thing and it should be viewed as a way you can think actively as you go into a situation. So, for shy people who feel worried about facing a particular challenge or event, Taylor advises slowly approaching the fearful situation if you start to feel anxious. By facing what you are not feeling secure about, Taylor says, you will feel less anxious. “Our brains are amazing—they can become well adapted,” he says. “If you put yourself in a fearful situation, you will get a sense that you are going to do it.” What’s more, shy individuals care deeply about what others think of them, and if it is addressed healthily, they can use it to their advantage to form social connections.
Shy people are observant and often pick up on parts of their conversation or surroundings that others may not. “Just because you are shy, that does not mean you are not used to social situations,” Taylor says. “It can actually become a source of strength as you are the observer in the room.” In a study out of Southern Illinois University at Carbondale, researchers found an association between college-age adults who were shy and the ability to better identify expressions of sadness and fear compared with those who weren’t shy. In addition, a shy person has a born drive to absorb a conversation, so they can be great at conversation.
1.In the opinion of C. Barr Taylor, we should .
A.think positively of shyness
B.try to get rid of shyness
C.attempt to be a little shy
D.often help those shy people
2.The passage mentions the study by Southern Illinois University just to show that .
A.shy people use rich facial expressions
B.shy people are good at observing others
C.shyness can be used to reduce anxiety
D.shyness can be used in social connections
3.We can know from the passage that shy people .
A.are good at getting used to a new environment
B.often attach much importance to others’ opinions
C.hate to think a lot before taking an action
D.are good at overcoming their feeling of insecurity
