A．guideB．showC．actD．behave

分析 孩子們如果不守規(guī)矩就不允許去超市．

解答 答案：D．
behave oneself 舉止規(guī)矩、得體，表現(xiàn)好，結合句意"孩子們如果不守規(guī)矩就不允許去超市．"可知，behave 符合題意，guide"指導"；show"展示"；act"行動"，均不符合題意，故選D．

7．"Drink your milk．It is good for you!"You've probably heard that many times，and it is true．Milk contains calcium，which is a necessary nutrient for keeping bones and teeth healthy and strong．The US government even requires milk as part of the National School Lunch Program，saying that students should drink one cup of fat-free milk at each meal．
Last Thursday，however，a group of doctors asked the government to remove the lunch program．The Physical Committee for Responsible Medicine says，"Milk is high in sugar，high in fat and high in animal protein，"all of which have negative effects on health．The PCRM says there were better and healthier ways to get calcium such as eating beans，broccoli，cereals and tofu．Orange juice and soymilk that have calcium added to them also supply the nutrient．"One of the only reasons people talk about dairy，or promote it at all，is because it is going to help build strong bones．"says Dr．Neal Bamard，president of the PCRM．But milk may not be the best way to get calcium your body needs．
Of course，calcium is important for health bones and teeth，but there are other things that affect your bone strength，such as genes，how much vitamin D you take in and getting an hour's worth of exercise every day．
Some nutritionists disagree with the idea that milk isn't important．Keri Gans，a dietitian，says，"I think it is irresponsible to take this beverage that children enjoy，especially among those who are unable to meet their nutrient needs for the day，and remove it from lunch time．"
The US government is studying the request of the PCRM，but a decision may be a one way to take off．Meanwhile，Marion Nestle，a professor at New York University，put it best："Milk demonstrably has nutrients．Other foods have the same nutrients．It's just a food．Like other foods，too much might be a problem．"
29．Why does the US government ask students to drink one cup of milk at lunch time？
D
A．They have been told many times．
B．They have taken the PCRM's advice．
C．Fat-free or low-fat milk is less expensive．
D．Milk helps build students'strong bones．
30．Which of the following opinions does the PCRM support？A
A．Milk is harmful to students'health．
B．Students should drink more milk each day．
C．Orange juice is higher in calcium than milk．
D．Milk is the best way to get calcium．
31．The underlined word"beverage"in Paragraph 4 most probably meansC．
A．gene        B．idea       C．milk       D．lunch
32．What does the above text mainly talk about？D
A．The best way to get the most calcium．
B．The connection between milk and health．
C．Different opinions about the importance of milk．
D．Whether to take milk off the school-lunch menu．

3．Pool Safety Tips for Kids
On a hot summer day，there are few things that are more appealing than a nice cool pool．（36）EAnd it is completely relaxing．Of course，if you have children，there are certain safety measures you should take，whether you have a pool in your backyard or are going to a public pool．
Go swimming together．No person should ever swim alone．Though many people do，the simple truth is that it only takes a second to become injured or drown．（37）FHaving someone there with you can make the difference between life and death．This is especially true for young children．If your child is under the age of 5，you should never allow them to swim out of arm's length．
（38）AKids love to chase one another through the water．But it is important that you emphasize to your children that at no time should they be running around the pool or pushing anyone．In the water，teach children not to jump on top of one another and to watch their surroundings，so that they do not accidentally knock into others，injuring them．Playing around in the pool is very interesting but dangerous．
Keep it locked．If you own a pool，you must have a locking gate around your pool．
（39）D Keep the gate locked at all times，even when you are physically in the pool．It is terrible for children to steal into the pool．
Know the way out．（40）BMake sure that they know where all ladders are，and that you teach them to use them for entering and exiting the pool safely．Although your child may be able to lift herself or himself out of the pool using the side，that is not the safest way to go．

A．Don't play around in the pool．
B．Be sure to show all children the proper way to exit the pool．
C．Swimming under water is forbidden in the poor．
D．This is to prevent children from entering the pool without your permission．
E．Slipping into the water seems like the perfect way to deal with the heat．
F．Something sad happens every year．
G．Make sure kids know food should be eaten either before or after swimming．

20．We often hear that children wish they（61）were（be） grown-ups，and that old people wish to be young．Each age has its own pleasures and its own pains．The happiest people enjoy（62）whateach age gives them without wasting their time in（63）useless（use） regrets．
Childhood is a time when there are few duties．A child（64）is fed（feed），looked after and loved by all grown-ups like parents or grandparents．What's more，life is always giving new things to him．（65）However，for older people they often lose their interest in those things．
On the other hand，a child may also have some pains with him．He is not so free to do what he wishes to do．He is often told not to do something．He will certainly be shouted（66）atfor doing something wrong．When a child grows up，he can no longer expect others（67）to pay（pay） for his food，〔lothes and many other things．And if he wants to live（68）comfortably（comfort），he has to work．If he still  spends most of his time（69）playing（play）as he used to in childhood，he will go hungry．If，however，he works hard and has no trouble，he can build up his own position  in  society  with great（70）happiness（happy）．
