Dear classmates,
I’ll tell everything about my future．Every 1._
one of us is thinking about the future．Do you know what 2._
yours is? I have decided to become a middle school teacher． 3._
Does it sound surprised? I had this dream when I was only 4._
a child．I love children．As we all can see, when teachers are 5._
great needed in our country, especially in the countryside．Many 6._
parents want their children to be well-educated, and they don’t 7._
want them to be teachers．Perhaps one of the main reason is 8._
that teachers work too hard but get too little．In spite that, I am 9._
determined to devote all my life to teach in my hometown． 10._
I remember my math teacher Mr．Young very well．He stood out because the kids made fun of him．He was missing one of his fingers, and always pointed at students with his middle finger．w．w I was not very good at English and math．No matter how hard I tried, I just could not figure out why I did not understand what all the other kids found so easy to learn．
One day, I was told that if I got one more E on my report card, I would be taken to the “big prison for kids”．
I tried really hard for weeks．I just couldn’t understand how to make different parts of numbers into whole things．
The day before report cards were to come out, I knew that Mr Young would give me an E, just like he always did．
I went to Mr．Young and told him that the orphanage （孤儿院） was going to send me to the big prison if I got another E on my report card．He told me there was nothing he could do; it would be unfair to the other kids if he gave me a better grade than I had actually earned．I smiled at him and said, “Mr．Young, do you know how the kids make fun of you because you’re missing your finger?”
He looked at me, moved his mouth to one side and said nothing．
“They shouldn’t do that to you because you can’t help not having a finger, Mr Young．Just like I can’t help not being able to learn numbers and stuff like that,” I said．
The next day, when I got my report card, I tucked it into one of my books．While on the school bus, I opened it: Geography, B+; Mechanical Drawing, C-; English, D-; History, C-; Gym, B+; Art, C; Math, D-．
That math grade was the most favorite one I ever received．Because I knew that someone in the world finally understood what it was like for me to be missing a finger inside my head．

I remember my math teacher Mr．Young very well．He suggests Ways to Burn More Calories．
Run through water
Running in water is one of the toughest activities you can perform because the wet stuff is about 12 to 15 times as resistant （具有阻力的） as air．Try your hardest to run and you can burn about 17 calories per minute．
Start fast
Don’t be fooled — slow and steady won’t win the race．A recent study found that after a short warm-up, cyclists who rode hard during the first half of their workouts and then slowed for the second half burned about 10 percent more calories than those who started slow and finished fast．
Take to the sand
Here is some easy-to-remember advice on burning calories: the softer the surface, the more you burn．By walking or running on the beach, you can use up 20 to 50 percent more calories than you do going at the same pace on a hard trail．
Shut up and dance
Here’s the perfect excuse to sign up for that hip-hop dance class you’ve been eager to try．Surprising your body with new activities — dance, a new sport, you name it — forces it to work harder because it’s doing unfamiliar movements and using muscle groups in different ways．
Use your arms
Getting both your upper and lower body involved can provide a big calorie-burning advantage．So if you’re short of time or want to get everything you can out of your usual 45-minute workout, try total-body activities, like rowing．You can swing your arms as hard as you can while you walk．
1.How can water help you burn more calories?
A．By pushing your body．
By
wetting your clothes and shoes．
C．By forcing you to run faster． D．By forcing your body to work harder．
2.What does “it” in Part 4 refer to?
A．dance
movement
C．body D．muscle
3.Which of the following statements is TRUE?
A．One can burn more calories when walking on the sand than on land．
One can burn more calories when walking on stones than on
earth．
C．One can burn more calories when running in water than on the sand．
D．One can burn more calories when exercising using the upper body than using the lower body．
