When Debbie Parkhurst choked on a piece of apple at her Maryland home, her dog jumped in, landing hard on her chest and forcing the piece of apple to pop out of her throat. Debbie Parkhurst’s husband, Kevin, was at his job at a Wilmington, Del., chemical firm when she took a midday break from jewelry and bit into an apple. When the Keesling family of Indiana were about to be overcome by carbon monoxide(CO), their cat clawed(抓) at wife Cathy’s hair until she woke up and called for help.
For their timely acts, Toby, a golden 2 1/2-year-old dog, and Winnie, a gray-eyed American shorthair, were named Dog and Cat of the Year by the American Society for the Prevention of Cruelty to Animals.
Neither Parkhurst nor Keesling could explain their pets’ timely heroics,though Parkhurst suggested it might have been guided by God intervention(干预). “That’s what our veterinarian(兽医) said,”she said. “He wasn’t making a joke; he’s very spiritual, and now I have to agree with him.”
But both pets were themselves rescued in baby, Toby as a 4-week-old baby thrown into a garbage bin to die, and Winnie as a week-old orphan hiding under a barn, so helpless that Keesling’s husband, Eric, had to feed her milk.
As the Keeslings recalled it, a gas-driven pump spread carbon monoxide through the house. By the time Winnie moved into rescue spot, the couple’s 14-year-old son, Michael, was already unconscious. “Winnie jumped on the bed and was clawing at me, with a kind of angry noise,” Cathy Keesling said. “When I woke up I felt like a T-bar had hit me across the head.”
State police and officers responding to her 911 call said the family was only minutes from death, judging by the amount of poisonous gas in the house.

People diet to look more attractive．Fish diet to avoid being beaten up，thrown out of their social group，and getting eaten as a result．That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists．
The research team have discovered that subordinate(低一等的) fish voluntarily diet to avoid challenging their larger competitors．"In studying gobies we noticed that only the largest two individuals，a male and female，had breeding（繁殖）rights within the group，" explains Marian Wong．"All other group members are nonbreeding females，each being 5-10% smaller than its next largest competitor．We wanted to find out how they maintain this precise size separation．"
The reason for the size difference was easy to see．Once a subordinate fish grows to within 5-10% of the size of its larger competitor，it causes a fight which usually ends in the smaller goby being driven away from the group．More often than not，the evicted fish is then eaten up．
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish．Whether they did so voluntarily，by restraining how much they ate，was not clear．The research team decided to do an experiment．They tried to fatten up some of the subordinate gobies to see what happened．To their surprise，the gobies simply refused the extra food they were offered，clearly preferring to remain small and avoid fights，over having a feast．
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group．Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves，so keeping their competitors small．
While the habits of gobies may seem a little mysterious，Dr．Wong explains that understanding the relationships between boss and subordinate animals is important to understand how hierarchical（等级的）societies remain stable．
The research has proved the fact that voluntary dieting is a habit far from exclusive to humans．"As yet，we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature，" the researchers comment．"Data on human dieting suggests that，while humans generally diet to improve health or increase attractiveness，rarely does it improve long-term health and males regularly prefer females that are fatter than the females' own ideal．"

Habits, whether good or bad, are gradually formed. When a person does a certain thing again, he is driven by some unseen force to do the same thing repeatedly, then a habit is formed. Once a habit is formed, it is difficult, and sometimes impossible, to get rid of. It is therefore very important that we should pay great attention to the formation of habits. Children often form bad habits, some of which remain with them as long as they live. Older persons also form bad habits lasting as long as they live, and sometimes become ruined by them.
There are other habits which, when formed in early life, are of great help. Many successful men say that much of their success has something to do with certain habits in early life, such as early rising, honesty and so on.
Among the habits which children should not form are laziness, lying, stealing and so on. These are all easily formed habits. Unfortunately older persons often form habits which could have been avoided(避免).
We should keep away from(远离) all these bad habits, and try to form such habits as will be good for ourselves and others.
40. ________ are formed little by little.
A. Good habits
B. Bad habits
C. Both good habits and bad habits
D. Either good habits or bad habits
41. The underlined word "them" in the first paragraph refers to ________.
A. bad habits B. good habits
C. children D. other persons
42. Generally speaking, it's difficult for one ________ and easy for them ________ which should be avoided.
A. to form bad habits; to form good habits
B. to form good habits; to form bad habits
C. to form such habits as will be good; to get rid of bad habits
D. to get rid of bad habits; to form good habits
43. Why should we pay much attention to the formation of habits?
A. Because habits are of great help to every one of us.
B. Because a man can never get rid of a habit.
C. Because it's hard and sometimes even impossible to throw away bad habits.
D. Because we are forced to do them again and again.
44. According to the passage, early rising ________.
A. has something to do with success
B. is an easily formed habit
C. is such a habit as should have been avoided
D. is such a habit as will be kept
查看习题详情和答案>>As the price of a college degree continues to rise, there's growing evidence that the monetary（货币的） payoff isn't quite as big as often advertised. The best estimate now is that a college degree is worth about $300,000 in today's dollars--nowhere near the million figure that is often quoted.
"That million number has driven me crazy!" says Sandy Baum, a Skidmore economist who studied the value of a college degree for the College Board last year.
Baum's research showed that college graduates earn, on average, about $20,000 a year more than those who finished their educations at high school. Add that up over a 40-year working life and the total differential is about $800,000, she figures. But since much of that bonus is earned many years from now, taking away the impact of inflation means that$800,000 in future dollars is worth only about $450,000 in today's dollars.
Then, if you remove the cost of a college degree--about ,$30,000 in tuition and books for students who get no aid and attend public in-state universities--and the money a student could have earned at a job instead of attending school, the real net value in today's dollars is somewhere in the $300,000 range, a number confirmed by other studies.
But, especially these days, that still makes a college degree one of the most lucrative investments a person can make, Baum notes.
Better yet, college graduates can go on to earn advanced degrees, which return even bigger payoffs. The average holder of a bachelor's degree earns about$51,000 a year, Baum calculates. But those who've gone on to earn MBAs, law degrees, or other professional degrees earn about $100,000 a year.
In addition, Baum found that there are plenty of other rewards for a degree. The quality of the jobs college graduates get is far better, for example. College graduates are more likely to get jobs with health insurance. And it is easier for them to find and hold jobs. The unemployment rate for college graduates was just 2.2 percent last year, half the unemployment level of those with only high school diplomas.
There are lots of other nonmonetary benefits as well. College graduates are healthier, contribute more to their communities, and raise kids who are better prepared academically, studies show.
Other researchers have found that the payoff of a degree is especially lucrative for students from low-income families, since the education and degrees give them a chance to break out of low-paying careers.
1.What can be inferred from Para 1 ?
A. The payoff of a college degree is still big enough to match the advertised.
B. It’s more and more difficult to get a college degree.
C. The return of a college degree is less than often quoted.
D. A college degree is worth about one million dollars.
2.Which of the following is closest in meaning to the underlined word “lucrative” in Para.5?
A. attractive B. worthless C. approachable D. balanced
3.How can a college graduate increase his or her yearly income according to the passage?
A. By getting jobs with health insurance immediately.
B. By going on for higher degrees.
C. By breaking out of low-paying jobs.
D. By contributing more to his or her community.
4.Which of the following statements can be learned from the text ?
A. According to Baum's research, high school graduates earn more than those who have college degrees.
B. College education is enough to ensure you a good life.
C. Nonmonetary benefits from the degree attract students more than monetary ones.
D. Students from low-income families still think degrees are profitable to change their life.
