Never put off till tomorrow what you can do today. 6 If you get behind the class, it is very difficult to get back in front. You cannot finish a race if you rest all the time.
7 Everyone will fail in some tests, lose some matches and have bad days. Don’t make small problems seem very big and important.

【题目】A
When an earthquake hit a small town, many houses fell down. After the earthquake, all the newspapers reported many-stories about some of the families who were in trouble.
One Sunday, when I was reading a newspaper, a special picture touched me. It gave the clothing sizes of each family member. I thought that this would be a good chance to teach my children to help those who were less lucky than themselves. I said to my seven-year-old twins, Brad and Brett, and three-year-old daughter, Meghan, ＂We have so much, but these poor people now have nothing. We’ll share what we have with them.＂
I filled a box with foods and clothes. While I was doing this, I encouraged the children to choose their toys and donate some of their less favorite things. Meghan watched quietly as the boys took out their old toys and games and put them together. Then she walked away. A few minutes later she came back with Lucy, her much-loved doll. She put the doll on top of the other toys. ＂Oh, dear,＂ I said, ＂you don’t have to give Lucy. You love her so much. ＂ Meghan said, ＂Lucy makes me happy, Mommy. Maybe she’ll make another little girl happy, too.＂
I looked at Meghan for a long moment. She taught me a lesson. It’s easy to give something that we don’t want any more, but hard to give what we cherish, isn’t it?
【1】According to the passage, the writer has___________ children.
A. one span>B. two C. three D. four
【2】 The underlined word ＂donate＂ probably means___________.
A. 捐赠 B. 丢掉 C. 展出 D. 放好

【题目】B
People are interested in eating raw and whole foods (天然健康食品). They are usually digested more efficiently than cooked and processed foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients (营养) to be absorbed into the blood. In both cases, the result is obesity.
Processed foods contain chemical elements, which might confuse the stomach that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestion cycle. Then, the body’s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.
To stop this vicious circle in its tracks, people need to have healthy food that will balance the body. Eating the right types of raw and whole foods can help. It’s also important to restore our enzyme balance. We need to tell and avoid the foods that cause negative effects and eat the foods that increase enzyme production. If we truly want to change and help our body heal itself, we need to take an active approach.
【1】What can we learn from Paragraph 1?
A. It is essential for us to digest some fat.
B. Cooked and processed foods are healthier.
C. Foods with natural enzymes help us keep fit.
D. Absorbing many nutrients is beneficial to our health.
【2】Processed foods will probably __________.
A. stop body’s metabolism B. be difficult to digest
C. destroy body’s cells D. lead to obesity
【3】 What does the underlined word “vicious” in the last paragraph mean?
A. Harmful. B. Violent.
C. Automatic. D. Positive.
