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.

Imagine one day, the water taps in your house stop running. You have to buy water from shops. And still there isn’t enough for everyone. Your mother has to save the family’s shower water to do other things. Would you be able to stand that kind of life?
Probably not. But that’s what kids in Yemen are experiencing. Experts said Yemen is going to be the first country in the world to run out of water. According to a report, the capital, Sanaa, will run out of drinking water as early as 2025.
Because of the shortage, the government often cuts the water supply. Hannan, an 18-year-old from Lahej, told the Times: “In a good week we’ll have a water supply all week. But then the following week there will be water only for a day or two.”
Hannan said only rich people have enough water to use. They can buy water from the shops or from the water truck. Private companies own the trucks. They travel around the city every day to sell water – at very high prices.
“A lot of people can’t afford it,” she said.
The average person in Yemen uses 100 to 200 cubic meters of water per year. That is far below the international water poverty line of 1,000 cubic meters.
The government is thinking of making use of seawater. But it will cost a lot and it may not happen soon enough to help the people of Yemen.
1.The purpose of the text is to _______.
A．tell us what life is like in Yemen
B．draw our attention to water shortage
C．remind us how important water is
D．show us ways of solving problems
2.The underlined word “that” in Paragraph 2 refers to _____.
A．buying water from shops
B．drinking dirty water
C．suffering from water shortage
D．washing clothes with used water
3. Hannan described _____.
A．what her life is like
B．how beautiful Lahej is
C．how people use water fully
D．how heavy the traffic in Lahej is
4.The Yemen Government _____.
A．has found a practical solution
B．only cares about rich people
C．may try to make use of seawater
D．can do nothing about the water supply
5.We can infer from the text that _____.
A．Sanaa will run out of water in 10 years
B．Hannan is a teenager from a rich family
C．the capital of Yemen is developing fast
D．private companies make a lot of money
