Walking for the Heart Disease

 Walking is one of the most important steps for the recovery of heart disease. Time and speed are two vital aspects of walking for people with heart disease. One must walk for at least thirty five minutes per day.    1.     The following understanding will help them to walk.

Why walking?

Walking is a must for a heart patient.    2.   First, it reduces weight, controls sugar, and reduces stress. It also gives the joints (关节) enough movement, fresh air – if you walk in the morning. Regular walks help in the control of blood pressure. But the most important advantage is that it gives fitness to the heart.

    3.  

Start walking slowly. Gradually increase the speed. Feel when the angina (心绞痛) is about to come. Stop, the feeling will go away. Walk again, but now the speed will be slower than the last time. Keep walking now and the angina will not come. This is the correct speed.  

How to start?

Suppose, you are at the stage of Class I angina: start walking on Day One. Try to walk about 30 minutes. For Class II angina group, walking should be slow and they should start with 10-15 minutes. They should not walk fast. Class III angina patients should start with one minute at home on empty stomach. After two days, they should increase to two minutes.    4.   

However, do not walk more than ten minutes a time.

Dos and don’ts on physical activity:

Heart patients must also know that they can do most of the activities where the heart rate does not go up. Sitting in an office, talking over the phone, discussing, driving car are some of the activities which do not increase the heart’s speed.     5.    As a matter of fact, stresses can also lead to other illnesses.

A. It has a great number of advantages.

B. Walking plays a very important role in helping a heart patient recover.

C. How to roughly judge the proper walking speed?

D. What is more important for the heart patient is to know the speed of walking.

E. But avoid all kinds of stresses, as stress can increase the heart’s speed.

F. How to increase the speed of walking?

G. Gradually they should increase the time but not the speed. 

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.

   In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.

   Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer．

   "By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "

   Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.

Anyone driving between San Francisco and Los Angeles recently may have seen a Toyota Prius (丰田普锐斯) with a curious chimney-like cylinder (汽缸) on the roof. It is hard to notice that the person at the wheel was not actually driving.

   The car is a project of Google, which has been working in secret but in plain view on vehicles that can drive themselves, using artificial-intelligence software that can sense anything near the car. “The car is never unmanned,” the project leader Dr. Thrun wrote on Google’s company blog. He said a driver was always behind the wheel to take control if something went wrong.

The unmanned cars are still years from mass production, but technologists who have long dreamed of them believe that they can transform society as greatly as the Internet has.

Engineers consider the cars are safer because they react faster than humans, having 360-degree perception and never getting absent-minded, sleepy or drunk. And they state that lives may be saved and injuries avoided, as more than 30,000 people are killed by car accidents in the United States per year. The engineers say the technology could double the capacity of roads by allowing cars to drive more safely while closer together. Because the robot cars would eventually be less likely to crash, they could be built lighter, reducing fuel consumption. But of course, to be truly safer, the cars must be far more reliable than, say, today’s personal computers, which crash on occasion and are frequently infected with virus.

Google has started doing what might seem like a technology area unrelated to its bread-and-butter business as the king of Internet search and advertising. The self-driving car is an example of Google’s willingness to gamble on technology that may not pay off for years, Dr. Thrun said. One way Google might be able to profit is to provide information and navigation (导航) service for makers of unmanned vehicles, with a plan to make traveling safer, avoid accidents and reduce the carbon emission (排放).

But the arrival of driverless vehicles arouse legal issues, the Google researchers acknowledged. Under current law, a human must be in control of a car at all times. And in the event of an accident, who would be liable — the person behind the wheel or the maker of the software?

58. According to Google, the driverless car ______.

A. is without a human presence at all times         B. will react faster but be less reliable

C. will increase efficiency of road and fuel         D. will safely navigate the roadways

59. With its new invention, Google hopes the following except ______.

A. the driverless car will make a lot of sense       B. its business will reach beyond its usual range

C. it will profit by making unmanned vehicles      D. laws will have to catch up with the technology

60. The underlined word “liable” in last paragraph probably means “______”.

   A. dependable          B. responsible               C. trusted                            D. sensible

61. The best title of the passage might be ______.

A. Google Cars Drive Themselves in Traffic       B. Driverless Cars Could Be the Wave of Future

C. Google Hopes to Reduce Traffic Accidents            D. Unmanned Cars Closer to a Commercial Reality
