Are you bad at math? If you answer yes, consider this question: Are you bad at math because you didn't study hard enough to learn the material or because you lack the ability to be good at it?
As it turns out, many children believe that they don't do well on math tests because they're intellectually incapable (无能的) of understanding the material. They have no reason to try harder, thus trapping them in a state of being bad at math.
Educators Miles Kimball and Noah Smith argue that this is a big problem, “Math is the great mental subject of an unconfident America. If we can convince you that anyone can learn math, it should be a short step to convincing you that you can learn just about anything, if you work hard enough.”
Psychologist Carol Dweck took on the task of convincing a group of students that if they worked hard they could become smarter. The truly remarkable part

of that study was not that the kids improved and earned higher grades; it was that Dweck noted that a few of the tough boys in the group were brought to tears, learning that the level of intelligence they could reach was limitless — it was entirely up to them.
Of course, not all of us will become genius mathematicians, but the majority of us can become skilled and maybe even good at math. As Mashable points out, while dyscalculia (计算障碍), a math disability, is a real thing, only 6 percent of the population is likely to have it. For the rest of us, it's a confidence problem, or a lack of belief that with hard work, we'll improve. Thankfully, we now know better, and we can pass on that_information to the next generation. 4．Many people don't work hard at math because they think that ________. A．their intelligence is high B．math is not worth learning C．it's useless to put in the effort D．they have understood the material 5．According to Miles Kimball and Noah Smith, ________. A．math is a big problem to deal with B．most Americans don't like math at all C．math is an important subject at school
D．one can learn anything as long as he works hard 6．In Carol Dweck's study, the students ________.
A．passed the tests easily B．became good at math soon C．didn't get higher grades in the test
D．know their intelligence depends on themselves
7．What does the underlined part “that information” refer to? A．Math disability doesn't really exist. B．Everyone is likely to learn math well. C．Math cannot be ignored at any time. D．Confidence is important in one's life.

When she was studying to become a scientist, Megan Strauss rode in a small airplane to study giraffes. While a pilot flew over the Serengeti in Tanzania, Africa, the researchers looked down carefully and counted giraffes. \

amazed how easily we can spot warthogs and other small animals, yet we sometimes have trouble seeing giraffes. Giraffes are slender in shape, and they may not throw a good shadow, \says Dr. Strauss, who has since become a wildlife scientist. The Serengeti is about the size of Vermont, a state in the northeastern US, so the scientists could not study the entire area. Instead, they surveyed three areas where giraffes were studied in the 1970s. As they expected, they saw far fewer of these animals. To find out if lions had been killing more giraffes in recent years, the team looked at the survival of young giraffes. Lions kill more young giraffes than adults, but the team found no decrease in young giraffes' survival after they are born, compared with the 1970s. The team then looked at whether too many giraffes were being killed by parasites(寄生虫）.The researchers counted parasite eggs in giraffe droppings, and they found too few to harm the giraffe population. They looked into whether poachers (盗猎者)were killing too many giraffes. Two of the areas they studied are where giraffe meat is sometimes sold in local markets. Poachers catch more adult males than other giraffes. Researchers spotted too few males compared with females in those two areas, a sign of poaching. When the food supply is short, the environment supports fewer giraffes and the females have fewer young giraffes. A lot of new trees have grown in the Serengeti, but many are a type that giraffes do not like to eat. The researchers found fewer young giraffes today than in the 1970s compared with the number of adult females, a sign that food was in short supply. Dr. Strauss is working on an environmental education program for Tanzania including books for students. These materials will educate Tanzanians and help them to help giraffes. As knowledge grows and changes are made, they hope the giraffe population will increase.
8. What did Dr. Strauss find while studying giraffes in the Serengeti? A. It was too costly to study giraffes. B. It was hard to spot giraffes from the air. C. The number of giraffes had increased slowly. D. Giraffes lived in smaller areas than in the 1970s. 9.How did the team study the lion-giraffe relationship? A. By analyzing giraffe droppings. B. By comparing young giraffes with adults.

It began as a game: High school and college students studying computer technology figured out they could use personal computers to break into telephone company computers and make free, long-distance telephone calls. These young computer talents soon gained the name \few hackers, but many went on to even more complex hacking. One of them was arrested for making illegal telephone calls and later he used a phone to change a police officer's credit records to get back at the officer for arresting him. He also used a computer to change his college records to give himself better grades. As hackers gained experience, they began invading computers at banks, airlines and other businesses. In one case a hacker instructed an airline' s computer to give him free airplane tickets. The U.S. government is worried that hackers may break into its networks of defense computers. The government's secrets are easily attacked because thousands of government computers are connected by telephone lines that hackers can get into. In November 1988, a college student entered a U.S. Defense Department computer network called Arpanet. The hacker injected a computer program that made copies of itself throughout Arpanet. Some hackers use viruses to destroy all the data in a computer. But in this case, government officials shut down the network before the program reached every computer in the system. Shutting down the system angered many researchers who were using the computers. The hacker turned himself in to the police and he was charged with a crime. The incident put the spotlight on computer hacking in the United States. Many companies have hired experts to
