If doctors want to test you for something, they’ll usually take a blood or urine sample (尿样). But wouldn’t it be much more convenient if they just asked you to breathe through a special instrument?
In fact, your breath can say a lot about you. In traditional Chinese medicine, doctors draw a conclusion about the health state of a patient based on the smell of his or her breath; trained dogs and rats can identify the smells of the breaths of people suffering from certain cancers; traffic police also monitor drivers’ alcohol consumption by testing their breaths.
Just like blood and urine, your breath contains lots of “ metabolites ” --- the waste chemicals that the body produces, which vary from person to person. They are like personal health fingerprints, which is why scientists sometimes call them “ breath prints”, according to Science Daily.
Compared to blood or urine testing, breath testing takes only seconds instead of hours, and it requires neither a needle nor a container to hold the body fluids (体液). This means the test can be taken frequently to better detect early signs of diseases and monitor the progress of a medical treatment.
On the other hand, as an identifier, you might think that breaths are not as reliable as fingerprints since they might change based on what you eat. However, researchers in Zurich, Switzerland mapped 11 healthy volunteers’ chemical patterns by having them breathe through a special instrument, and they found that each pattern was unique and the patterns didn’t change much throughout the day, reported BBC.
“Our goal is to develop breath analysis to the point where it becomes competitive with the established analysis of blood and urine,” said Malcolm Kohler, professor at the University Hospital Zurich.
1.According to the text we know that __________.
A. breath varies from person to person based on food
B. your breath may give you away if you are not careful
C. doctors can test one’s breath to find about his illness
D. dogs can identify people with certain cancers
2.In comparison with blood or urine testing, breath testing is __________.
A. comfortable and convincing
B. traditional and reliable
C. accurate and competitive
D. quick and convenient
3.What is the author’s attitude toward breath testing?
A. Doubtful. B. Approving.
C. Unconcerned. D. Worried.
4.What can we infer from the text?
A. Breath testing is reliable and may have a bright future.

C. Doctors have found the best way to detect early signs of diseases.
D. Traditional Chinese medicine is becoming more and more popular.

If you want to learn why everything is usually cheaper, and what items are the best deals at your local or chain dollar or discount store, store employees have a lot of useful information. They tend to know what shoppers want — even before shoppers know themselves.
Everyone buys unnecessary things
Whether you shop at a chain dollar store such as Dollar Tree, Family Dollar or your local 99 cents store, not everything that’s on sale is necessarily worth purchasing. Bryan Waring, a former Dollar Tree employee, says that you’re not alone in buying more than necessary from these stores. “It seems basic, but everyone falls for this trap,” he says. “You go into a store where everything is cheap, and you walk out with things you don't need.” He suggests going into a store — yes, even the dollar store — with a checklist of things you truly need.
Everything is cheaper after the holiday season
Patricia, a seasonal worker at a Dollar Tree, says that the post-Christmas season means even more deals on everything from decorations to sweets. “After Christmas, all the gift wrap paper went to 50 cents, and all Christmas items were half price,” she says. “Even candy bars are 89 cents versus $ 1.”
Products are less expensive because of their size
In order for dollar stores to keep their prices low, product sizes are usually smaller than normal, according to Cheapism. Dollar stores area t the only ones guilty of this trick. Cheapism also reports Walmart is guilty of doing the same thing to attract customers.
1.What is Bryan’s advice against buying unnecessary things?
A.Making a purchase alone.
B.Writing a to-buy list ahead.
C.Shopping at your local store.
D.Buying basic things separately.
2.Which of the following is a better time for shopping according to Patricia?
A.In the Christmas sales.
B.At a particular discount.
C.After the Christmas season.
D.During some holiday seasons.
3.How do stores make their products cheaper?
A.By reducing product sizes.
B.By lowering product costs.
C.By adopting discount strategies.
D.By attracting more customers.
