    Why is setting goals important? Instead of just letting life happen to you, goals allow you to make your life happen. Successful people imagine how their life should be and set lots of goals.

    By setting goals you are taking control of your life. It's like having a map to show you where you want to go. Think of it this way. There are two drivers. One has a destination in mind which can be found on a map. She can drive straight there surely without any wasted time of wrong turns. She starts off at the same time from the same place as the first driver, but she drives aimlessly around, never getting anywhere, just using up gas. Which driver do you want to be?

    Winners in life set goals and follow them through. They decide what they want in life and then get there by making plans and setting goals. Goals aren't difficult to set and they aren't difficult to reach.

    You are the one who must decide what to achieve and in what direction to aim your life.

    Research tells us that when we write a goal down we are more likely to achieve it. Like a contract(合同) with yourself, they are harder to neglect or forget. Also when you write your goals in a particular way, you are able to make yourself continuously aware of situations that will bring you nearer to your goal.

A.Because everybody should have a goal in his mind.

B.Unsuccessful people usually just let life happen by accident.

C.The other driver has no goal, or destination or map.

D.It's difficult for a driver to reach his destination without a map.

E.It's up to you to find out what your goals really are.

F.Because goals can help you do, be, and experience everything you want in life.

G.Written goals can be reviewed regularly, and have more power.

阅读理解

    A couple of days ago, as the test results came out, my son and a group of his 13-year-old friends piled into the back seat of my car, ready for the last-day-of-school party at McDonald's. “Jack got a laptop for getting straight A's, and Laurie got a cell-phone,” one boy said. “Oh, yeah, and Sarah got an iPad, and she's only in third grade,” said another. “And how about Brian? He got $10 for each A.”

    I suddenly became concerned. These payoffs might get parents through grammar school, but what about high school and beyond? What would be left after the electric guitar, the cell-phone, and the DVD player?

    I saw the road ahead:As the homework load increased, my income would decrease.I saw my comfortable lifestyle disappear before my eyes — no more of those $5 bags of already-peeled organic carrots. No more organic anything!

    I started to feel surprised and nervous. Would every goal achieved by my two children fetch a reward? A high grade point average? A good class ranking? Would sports achievements be included in this reward system: soccer goals, touchdowns? What about the orchestra? Would first chair pay more than second? I'd be penniless by eighth-grade graduation.

    “We never paid anything for good grades,” said my neighbor across the street, whose son was recently accepted at MIT. “He just did it on his own. Maybe once in a while we went out for pizza, but that's about it.”

    Don't you just hate that? We're all running around looking for the MP3 player with the most updates, and she's spending a few dollars on pizza. She gets motivation; we get negotiation. And what about the primary grades? What do these students get? “When the teacher asked if anyone got rewards for good grades, everyone in my class raised their hands and said they got ice cream cones ,” said one third-grader.

  1. (1) What's the best title for the passage?

    A . Tips on Paying Kids for Good Grades B . New changes in Paying Kids for Good Grades C . Good Grades Mean Good Rewards D . Don't Pay Kids for Good Grades
  2. (2) What does the underlined sentence in the third paragraph probably mean?

    A . Taking care of my children would influence my work. B . I would spend less money on my children's good grades. C . More rewards would be needed as my children grow up. D . Reducing my children's homework load would cost me a lot.
  3. (3) It can be inferred from the passage that ________.

    A . if you buy children pizza as a reward, they will work harder B . if you pay kids for good grades, they will take it for granted C . children will not ask for rewards when they enter high school D . good grades won't help kids make great progress in the future
  4. (4) The author takes her neighbor as an example to show _______.

    A . pizza is the best way to motivate children B . it is necessary to reward children for their good grades C . getting rewards for good grades is common nowadays D . rewards are not the only way to encourage children
