LIPITOR
ABOUT LIPITOR
Lipitor is a prescription medicine. Along with diet and exercise, it lowers “bad” cholesterol (胆固醇) in your blood. It can also raise “good” cholesterol. Lipitor can lower the risk of heart attack in patients with several common risk factors, including family history of early heart disease, high blood pressure, age and smoking .
WHO IS LIPITOR FOR?
Who can take LIPITOR:
· People who cannot lower their cholesterol enough with diet and exercise.
· Adults and children over l0.
Who should NOT take LIPITOR:
· Women who are pregnant, may be pregnant, or may become pregnant. Lipitor may harm
your unborn baby.
· Women who are breast-feeding. Lipitor can pass into your breast milk and may harm your
baby.
· People with liver (肝脏) problems.
POSSIBLE SIDE EFFECTS OF LIPITOR
Serious side effects in a small number of people:
· Muscle (肌肉) problems that can lead to kidney (肾脏) problems, including kidney failure.
· Liver problems. Your doctor may do blood tests to check your liver before you start Lipitor
and while you are taking it.
Call your doctor right away if you have:
· Unexplained muscle pain or weakness, especially if you have a fever or feel very tired.
· Swelling of the face, lips, tongue, and/or throat that may cause difficulty in breathing or
swallowing.
· Stomach pain.
Some common side effects of LIPITOR are:
· Muscle pain.
· Upset stomach.
· Changes in some blood tests.
HOW TO TAKE LIPITOR
DO:
· Take Lipitor as prescribed by your doctor.
· Try to eat heart-healthy foods while you take Lipitor.
· Take Lipitor at any time of day, with or without food.
· If you miss a dose (一剂), take it as soon as you remember. But if it has been more than 12
hours since your missed dose, wait. Take the next dose at your regular time.
Don’t:
· Do not change or stop your dose before talking to your doctor.
· Do not start new medicines before talking to your doctor.
1.Taking Lipitor is helpful for _________.
A. breast-feeding women
B. women who are pregnant
C. adults having heart disease
D. teenagers with liver problems
2.If it has been over 12 hours since you missed a dose, you should _________.
A. take the next dose at your regular time
B. eat more when taking your next dose
C. have a dose as soon as you remember
D. change the amount of your next dose
3.What is the main purpose of the passage?
A. To teach patients ways for quick recovery.
B. To present a report on a scientific research.
C. To show the importance of a good lifestyle.
D. To give information about a kind of medicine.

Why Blue LED Lights Won the Nobel
The 2014 Nobel Prize in physics went to three scientists who gave lighting a big change by inventing blue LED lights. A big change in lighting efficiency is under way around the world.
Save and green
LEDs use less energy than other forms of lighting. A typical LED bulb(灯泡) can produce around 83 lumens per watt — a measure of how much brightness you can get from a unit of electrical power — much more efficient than other lighting facilities.
LEDs produce light by passing electric current through a semiconductor, while traditional bulbs pass current through a wire. The wasted heat energy is chiefly why traditional bulbs are so much less efficient.
LEDs also last about 30 times longer than traditional bulbs, and many LED bulb products promise up to 25,000 hours of use — more than 17 years if you used one for about four hours a day.
Lighting the world
The lighting transformation is not only in homes. LEDs are also being used for street lights, public holiday and decorative displays, commercial buildings, and other large energy users.
Car lighting is another application where LEDs are making progress. LEDs used to be used only for daytime running lights, but now many new cars have LED headlights for night-time use.
LEDs also hold promise for bringing light to the more than 1.5 billion people around the world without access to electricity, the Royal Swedish Academy of Sciences noted. Indeed, several proposed solutions to energy poverty include the distribution of LED lights, particularly solar-powered ones.
Digital displays
Without blue LEDs, the world wouldn’t have back-lit smart phones, TV and computer LCD screens, blu-ray(蓝光) players, many forms of lighting, and countless other products.
In the electronics industry, LEDs provide back lighting for LCD screens in many smart phones, laptops, and televisions. The LEDs are more energy efficient and allow for very thin displays.
Blu-ray players use blue LED lasers(激光) to read data off a digital optical disc. When these systems switched from using an infrared(红外线) laser to a blue LED laser, it became possible to store five to 10 times as much data.
LEDs are now being explored for their potential uses to transmit(传送) data from the Internet across open space, similar to WiFi. Such a system could transmit a lot more data than WiFi alone. This high bandwidth is possible because LEDs can turn on and off millions of times per second.
The rise of LED lighting came at a time when people were just starting to be concerned about global warming. Because of LEDs’ energy efficiency, using them for the world’s lighting would affect environmental protection in a positive way.
