Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth’s changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.
 3.5℃
    This is how much temperatures would rise by 2100 even if nations live up to the initial Paris promises to reduce carbon emissions; this rise could still put coastal cities under water and drive over half of all species to extinction.
2℃
    To meet this minimum goal, the Agreement requires countries to tighten emissions targets every five years. Even this increase could sink some islands, worse drought(干旱) and drive a decline of up to a third in the number of species.
1.5℃
    This is the most ambitious goal for temperature rise set by the Paris Agreement, after a push by low-lying island nations like Kiribati, which say limiting temperature rise to 1.5℃ could save them from sinking.
 0.8℃
    This is how much temperatures have risen since the industrial age began, putting us 40% of the way to the 2℃ point.
0℃
    The baseline here is average global temperature before the start of the industrial age.
25. It can be concluded from paragraph 1 that _______.   
A. the problem of global warming will have been quite solved by 2020
B. gas emissions have been effectively reduced in developed countries
C. the Paris Agreements is more influential than the Kyoto Protocol
D. humans have made continuous efforts to slow down global warming
26. If nations could only keep the initial promises of the Paris Agreement, what would happen by the year 2100?
  A. The human population would increase by one third.
B. Little over 50% of all species would still exist.
C. Nations would not need to tighten their emissions targets.
D. The Agreement’s minimum goal would not be reached.
27. If those island nations not far above sea level are to survive, the maximum temperature rise, since the start of the industrial age, should be_______.
A. 0.8℃     B. 1.5℃     C. 2℃       D. 3.5℃

Parents do need to teach their kids financial responsibility and that money is earned. Still, many child-development experts agree that tying a child’s allowance to chores can be a slippery slope. Here’s why.
    Susie Walton, master instructor at Peace in Your Home advises to keep chores and allowances totally separate. “Allowance is one thing. When it comes to chores, life skills, responsibilities－that’s a whole different thing.” says Walton.
    Walton says, “When kids aren’t doing a chore, you don't say, ‘well, there goes your allowance.’ You’re going to sit them down and ask what’s going on. ‘We are a team. We are a family. We’ve got to have them done.’”
    Besides, by paying children for chores with an allowance, you’ll also be sending the message that work isn't worth doing unless they’re getting paid for it.
    There are times when it would make sense to pay kids for chores. Most financial and child-development experts agree that it’s a fine idea to pay children money for extra jobs that are outside their normal set of chores, such as washing windows, washing the car or helping to clean out the garage－especially if the child is saving for a big item. This may even develop an entrepreneurial (企业家的) spirit to think outside of the box to earn money.
    For parents who are concerned that their children won’t learn the value of a dollar if the allowance isn’t tied to household chores, note that there are still plenty of money management skills to be learned from a straight allowance. Depending on the age, kids can be made responsible for paying for their own toys or snacks. Some parents even require that kids set aside a percentage of their allowance toward savings.
    “I really like having my own money,” says Kevin, 9. “It’s up to me if I want to buy the cheap toy now, or save and get the better toy.” And that’s a good lesson to learn at 9 years old.
    No matter which allowance route you take in parenthood, kids will feel empowered by being able to handle their own money.
28. Which of the following would Susie Walton most probably agree with?
    A. A child’s allowance shouldn’t be tied to chores.     
   B. Kids shouldn’t be forced to do chores.
    C. Doing chores teaches kids the value of work.       
   D. Kids should be paid for doing chores.
29. According to Susie Walton, if kids don’t do chores, parents should ______.
    A. teach them the entrepreneurial spirit         
   B. talk to them about family responsibilities.
    C. give them a smaller allowance than usual     
   D. punish them by not giving them their allowances
30. What is the author’s attitude towards Kevin’s action?
    A. Worried.     B. Doubtful.    C. Approving.    D. Unfavorable.
31. The text is mainly about _____________.
    A. the importance of kids doing chores
    B. whether parents should pay kids for chores
    C. the advantages of kids handling their own money
    D. whether parents should give kids regular allowances
