In the normal walk of life, we come across people who are more popular than others. Popularity is a subjective phenomenon and many a sociologist is still trying to figure out what makes for popularity. A person with a bright personality is usually more popular than a person with a dull personality, right？ Beautiful people are usually more popular than ugly people, right？ Actually, it's hard to pinpoint (确定) what kind of personality is popular and what is unpopular.
Behavior. can be described as the manifestation of personality in response to a situation. No two persons will react to the same situation in the same manner. This is because of the person's personality. Let's take the example of an introvert and an extrovert. We shall create a situation to study how they behave in the same environment. The introvert and the extrovert are placed into two identical rooms at the same time. Every effort is taken to ensure that the environment is the same. They are told to read a book in 2 hours. Then, we ask a group of hooligans (小流氓) to go into the rooms and beat the rooms. How do you think the introvert and the extrovert will behave in such an environment？ We don't know but we know they will behave differently.
Are you satisfied with how your career is turning out？ You may not consciously know it but your personality has a great bearing of your job performance. If you are extremely shy and hate to socialize, you are not cut for a sales job or a PR(公共关系)position. You may try to change your ways and take on a more outgoing style. but you may not be happy. There are some personality characters which are inherent. If you know yourself well, you will find a career that suits your personality and excel in it.
We may infer from the first paragraph that______.
A．we have to face the world with masks
B．personality can be shown through one's actions
C．people's personalities are all fixed through their life
D．people's personalities are totally different from each other
听力原文： That's how Shown O'Neill looks back on the heart attack he experienced shortly after his 31st birthday.
"I thought I was in perfect health," Shown says. "I was never sick. I woke up feeling good every morning."
Then on that fateful day in April 2002, he received a giant eye opener. He was working in his yard in Hixson and started having pain in his chest and arms. "I wag pretty sure what it was, but I couldn't believe it could be happening to roe." The good news is that because Shawn recognized the symptoms and went immediately to Memorial Noah Park Hospital, he received the treatment he needed and the damage to his heart muscle was minimal.
"Advances in medicine make it possible for us to stop many heart attacks and keep people alive if they get to the hospital in time," says Dr: Kinsman Wright, medical director of Cardiac Services at Memorial. "We have technology to pinpoint blockage in the cardiac, arteries and several options to open the vessels. And lifestyle. changes and medications are helping people reduce their risk factors."
But Dr. Wright doesn't see any decrease in heart disease. "With people living longer, we're seeing different types of heart disease. We need to keep studying and fighting it on all fronts."
(30)
A．Yes. Because he is never sick.
B．Yes. Because he wakes up feeling good every morning
C．No. Because his heart muscle was severely, damaged.
D．No. Because he suffered a heart attack.
These phones and their related tracking services allow parents to pinpoint the location of their children with ease. Parents agree to pick up the phone bill in return for the reassurance of knowing where their children are; children are prepared to put up with the watching if they are allowed to have a phone.
Mobile operators in America are now launching tracking services. Under a federal decree known as E911, they had to upgrade their networks to ensure that anyone dialing the 911 emergency number could be located to within 100 metres. Some operators opted for triangulation technology, which determines the location of the handset by comparing the signals received by different base stations. But Verizon and Sprint chose to adopt the more expensive but more accurate GPS technology instead, and are now looking for ways to make money from it.
Verizon calls its service "Chaperone". For $10 a month, parents can call up the location of their child's LG Migo handset from their own mobile phones, or from a PC. The child receives a message saying that the handset's position has been requested, and the parents receive an ad dress, or a marker on a web-based map, giving the child's location. For an extra $10 per month, they can sign up for Child Zone, a service that, among other things, fires off an alert when a youngster (or, at least, the youngster's handset) strays outside a specified area.
For its part, Sprint has launched a similar service that can also let parents know when a child arrives at a particular location.
Another location service is available from Nextel, a mobile operator that was taken over by Sprint in 2005. Nextel opened up some of its systems to enable other firms to build their own software and services on top of its GPS technology. One example is AccuTracking, a small company which offers a tracking service for $6 a month and boasts that it is "ideal for vehicle tracking" or to keep "virtual eyes on kids". Some customers are also using the service to track their spouses, by hiding phones in their cars. "Mine is hidden under the hood, hot-wired to the battery—it works very well and it is easy to hook up continuous power, "writes one customer on AccuTracking's message board.
Start-ups are working on everything from city-wide games of hide-and-seek to monitoring the locations of Alzheimer's patients. Services that monitor jogging routes, and work out distance travelled and calories consumed, might also prove popular.
As a result, mobile operators, handset-makers and start-ups could transform. and expand a small, specialist market so far dominated by expensive, dedicated tracking systems.
The tracking function of the mobile networks was probably first intended for ______.
A．federal officials
B．national security
C．parent consumers
D．emergency rescue
