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.
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

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

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

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.

Why do people drink too much, eat too much, smoke cigarettes or take drugs? What’s to blame for all the bad behavior? Most people would say that, while these self-destructive (自我毁灭的) acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist(抵抗) them.
According to a recent study, however, if you really think about it, something about that simple answer doesn’t quite make sense. In fact, it turns out that sometimes it’s having will power that really gets you into trouble.
Think back to the time you took your very first sip (啜饮) of beer. Disgusting, wasn’t it? When my father gave me my first taste of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette — it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation (诱惑) you need will power to resist, they never, ever start out that way.
Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (讽刺的是), only those who can control themselves well, rather than give in to them, can ever come to someday develop a “taste” for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, in order to seem experienced, grown-up, and cool.
These bad habits aren’t self-control failures — far from it. They are voluntary choices, and they are in fact self-control successes. Self-control is simply a tool to be put to some use, helpful or harmful. To live happy and productive lives, we need to develop not only our self-control, but also the wisdom to make good decisions about when and where to apply it.
What do most people think causes bad behavior?

A.Being forced by others.
B.Not having enough will power.
C.Enjoying their first experiences.
D.Following the examples of their friends.

The author mentions his experience in the third paragraph to prove ____.

A.will power helps develop bad habits sometimes
B.drinking beer is harmful to the health of teenagers
C.self-control should be developed when one is young
D.everyone can be challenged by different temptations

In the last paragraph, the author stresses that ____.

A.without self-control, no one can succeed
B.bad habits don’t always lead to bad results
C.applying self-control correctly is important
D.people can develop wisdom from bad behavior

What would be the best title for the passage?

A.My First Sip of Beer B.Do You Have Will Power ?
C.Will Power Benefits Us D.Dark Side of Self-control

Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of you look the same age !
You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change your clothes’ color or pattern.
You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn’t drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip.
It’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve(袖子). Such “smart technology” is all around you.

F. Scott Fitzgerald, born on September 24, 1896, an American novelist, was once a student of St. Paul Academy, the Newman School and attended Princeton University for a short while. In 1917 he joined the army and was posted in Alabama, where he met his future wife Zelda Sayre. Then he had to make some money to impress her.
His life with her was full of great happiness, as he wrote in his diary, “My own happiness in the past often approached such joy that I could not share it even with the person dearest to me but had to walk it away in quiet streets and take down parts of it in my diary.”
This side of paradise, his first novel, was published in 1920. Encouraged by its success, Fitzgerald began to devote more time to his writing. Then he continued with the novel The Beautiful and Damned (1922), a collection of short stories Tales of the Jazz Age (1922), and a play The Vegetable (1923). But his greatest success was The Great Gatsby, published in 1925, which quickly brought him praise from the literary world. Yet it failed to give him the needed financial security. Then, in 1926, he published another collection of short stories All the Sad Young Men.
However, Fitzgerald’s problems with his wife Zelda affected his writing. During the 1920s he tried to reorder his life, but failed. By 1930, his wife had her first breakdown and went to a Swiss clinic. During this period he completed novels Tender Is the Night in 1934 and The Love of the Last Tycoon in 1940. While his wife was in hospital in the United States, he got totally addicted to alcohol. Sheila Graham, his dear friend, helped him fight his alcoholism.(酗酒)

How many novels written by Fitzgerald are mentioned in the passage?

A.5. B.6. C.7. D.8.

We can infer from the passage that Fitzgerald .

A.had made some money when he met Zelda in Alabama
B.was well educated and well off before he served in the army
C.would have completed more works if his wife hadn’t broken down
D.helped his friend get rid of drinking while his wife was in hospital

The passage is probably followed by a concluding paragraph about .

A.Zelda’s personal life
B.Zelda’s illness and treatment
C.Fitzgerald’s friendship with Graham
D.Fitzgerald’s contributions to the literary world
