When people get a bad toothache, they often have to eat soft, easily chewed food. ___1.__ That’s the conclusion of a zoologist at the Field Museum of Natural History in Chicago and a dentist who works on carnivores (食肉动物).
___2.__ Every once in a while, however, a lion will go on a human-eating diet. The most famous such tragedy happened in 1898, when two lions killed and ate 135 railway workers in Kenya.
Examining the preserved skulls of the two big lions, zoologist Bruce Patterson and dentist Ellis Neiburger found that both animals had been suffering from several dental and jaw problems. ___3.___ Canines are pointed teeth that hunting animals use for gripping and piercing prey .
The two lions might have been so badly disabled that they couldn’t bite down forcefully, say the researchers. Consequently, the lions might have abandoned their normal, more difficult prey and turned to humans. Patterson said “____4._____ We’re very slow, we don’t hear very well, and we don’t see very well in the darkness.”
______5.____ It was inspired partly by the work of Jim Corbett, a tiger hunter in India in the 1930s. Corbett was regularly called in to hunt tigers that had been dining on Indian villagers. Time after time, Patterson discovered that the killer tigers were suffering from some ill-healthy conditions.

A. Humans are easy preys.
B. Lions don’t normally prey on people.
C. When lions get a bad toothache, they eat people
D. One lion had three missing teeth and a loose, unsteady lower canine that was probably useless.
E. The research calls their idea the Infirmity Theory.
F. He had absolutely no experience taking medicine.
G. Talking about it in the abstract isn’t enough.
Can you imagine a stranger will read your e-mails without your permission or scan the website you’ve visited or perhaps someone will casually glance through your credit card purchases or cell phones bills? All of the things may happen to you one day.
In fact, it’s likely that some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen or even do something that may bring a disaster to you.
Psychologists tell us boundaries are healthy, and that it’s important to reveal to friends, family and lovers at appropriate times. But few boundaries remain nowadays. The digital bread crumbs you leave everywhere make it easy for strangers to know who you are, where you are and what you like. In some cases, a simple Google search can leak the deepest thought in your mind. Like it or not, increasingly we live in a world where you simply cannot keep a secret.
The key question is: Does that matter? For many Americans, the answer apparently is “No”.
When opinion polls ask Americans about privacy, most of them say they are really concerned about losing it. And 60 percent of the respondents say they feel their privacy is “slipping away, and that bothers me”.
But people say one thing and do another. Only a small of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths(收费站) to avoid using the EZ-Pass system that track automobile movements. Privacy economist Acquisti has run a series of tests that reveal people will give up personal information such as telephone number, address, or social security numbers just to get their hands on a pitiful 50-cent-off coupon(优惠券). But privacy does matter—at least sometimes. It’s like health; when you have it, you don’t notice it. Only when it’s gone do you wish you’d done more to protect it. Without privacy, one will be naked in front of others.

D．The information Age Has Its Own Shortcomings |
It is common for older people to forget things. Now an American study has found that memory starts to fail when we are young adults. People younger than thirty years of age usually do not know that they are starting to forget information. But scientists from the University of Michigan say the loss of memory has usually already started.
Researchers say people do not observe this slow reduction in mental ability until the loss affects their everyday activities.
Denise Park led the new study. She directs the Centre for Aging and Cognition at the Institute for Social Research at the University of Michigan. Her team studied more than 350 men and women between the ages of twenty and ninety years. The study identified people in their middle twenties with memory problems.
She says young adults do not know they are forgetting things because their brains have more information than they need.
But she says that people in their twenties and thirties are losing memory at the same rate as people in their sixties and seventies.
Ms. Park says people between the ages of sixty and seventy may note the decrease in their mental abilities. They begin to observe that they are having more trouble remembering and learning new information.
The study found that older adults are more likely to remember false information as being true. For example, they remembered false medical claims as being true. Younger people remembered hearing the information. But they were more likely to remember that it was false.
Ms. Park is now using modern imaging equipment to study what happens in the brains of people of different ages. She is studying what parts of the brain older adults use for different activities compared to younger adults. Ms. Park says mental performance is a direct result of brain activity and brain structure. She says keeping the brain active is important. She hopes future studies will identify ways to improve the operation of our aging minds.
