Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.
That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.What is the best possible title of the passage?

Do you enjoy reading? Do you read newspapers or magazines? Chances are, if you do any of these activities, your pre-school child is on his way to becoming a reader.
The process of learning to read is complex, and one of the most important things to know is that parents can help their children learn to read. As children have conversations with adults, they hear both ne
w and familiar words and their vocabulary grows.
There are many opportunities for adults and children to talk together, such as when riding in the car or in a bus, doing housework like fixing dinner, or bathing and getting ready
for bed. A major part of conversation is listening. When children talk, adults listen and respond. Then children listen and respond, and so the flow of conversation happens.
Have you watched you pre-school child pretend to read to his younger sisters or brothers? Have you read his favorite story over and over? These experiences tell children that reading is fun. And when things are fun and they are repeated, your child will see letters. He begins to connect them to familiar words, especially the letters that make up his name. A natural next step for him to take is to write the letters.
When children see parents make a grocery list, they want to use a pencil and paper to make their own list. To encourage these beginning writing activities, have pencils, markers, crayons and scrap paper within your children’s reach.
The more children get connected with talking, listening, reading and writing, the easier it is for them to become active readers. While you as a parent have a big influence on these early 
behaviors, it is important to remember that opportunities for literacy experiences happen when you and your child share in the basic routines（日常生活）of everyday life. The third paragraph tells us that parents can talk with their children__________.
| A．during daily routines | B．only in quiet places |
| C．in their spare time | D．when they are eager to walk |
During the process of learning to read, children may _________.
| A．copy the action of the adults. |
| B．prefer to talk with those of their own age. |
| C．show no interest in reading at all. |
| D．waste a lot of paper and other materials. |
When do children want to learn to write?
| A．When their parents ask them to do so. |
| B．When they believe they can write well. |
| C．When they know what they want to know |
| D．When they can connect letters with familiar words. |
The passage is written to _____________.
| A．talk about parents’ influence on their children’s behavior |
| B．encourage parents to set a good example to their children |
| C．advise parents to make reading a part of their children’s daily life |
| D．make parents believe in the importance of early reading |
Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedrooms TVs.
A second study, looking at nearly 1,000 grown-ups in New Zealand, found lower education levels among 26-year-olds who had watched lots of TV during childhood. But the results don’t prove that TV is the cause and don’t rule out that already poorly motivated youngsters(年轻人)may watch lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15. Those with college degrees had watched an average of less than two hours of TV per weeknight during childhood, compared with an average of more than 2½
hours for those who had no education beyond high school.
In the California study, children with TVs in their rooms but no computer at home scored the lowest, while those with no bedroom TV but who had home computers scor
ed the highest.
While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumula
t
ing findings that children shouldn’t have TVs in their bedrooms.According to the California study, the low-scoring group might____________.
| A．have watched a lot of TV |
| B．not be interested in math |
| C．be unable to go to college |
| D．have had computers in their bedrooms |
What can we learn from the last two paragraphs?
| A．More time should be spent on computers. |
| B．Children should be forbidden from watching TV. |
| C．TV sets shouldn’t be allowed in children’s bedrooms. |
| D．Further studies on high-achieving students should be done. |
What would be the best title for this text?
| A．Computers or Television |
| B．Effects of Television on Children |
| C．Studies on TV and College Education |
| D．Television and Children’s Learning Habits |
As one comes to some crossroads, he or she sees a sign which says that drivers have to stop when they come to the main road ahead. At other crossroads, drivers have to go slow, but they do not actually have to stop unless, of course, there is something coming along the main road; and at still others, they do not have either to stop or to go slow, because they are themselves on the main road.
Mr. Williams, who was always a very careful driver, was driving home from work one evening when he came to a crossroad. It had a “SLOW” sign. He slowed down when he came to the main road, looked both ways to see that nothing was coming, and then drove across without stopping completely.
At once he heard a police whistle, so he pulled into the side of the road and stopped. A policeman walked over to him with a notebook and a pen in his hand and said, “You didn’t stop at that crossing.”
“But the sign there doesn't say ‘STOP’.” answered Mr. Williams, “It just says ‘SLOW’, and I did go slow.”
The policeman looked around him, and a look of surprise came over his face. Then he put his notebook and pen away, scratched his head and said, “Well, I’m in the wrong street!”When he was stopped by a policeman, he ____.

To help the environment, many Americans have made the change from paper and plastic bags to reusable grocery bags. But a report by a Florida newspaper says that reusable grocery bags sold by some supermarkets contain high levels of lead(铅). Lead is a metal that can be harmful to humans, especially young children, Now, Senator Charles Schumer is asking the US government to investigate(调查) the use of lead in reusable shopping bags.
“When our families go to the grocery store looking for safe and healthy foods to feed their kids, the last thing they should have to worry about is poisonous bags.” Schumer said, “A quick investigation will allow everyone to make informed, timely decisions.” Schumer added.
Lead in the bags is not likely to rub off (因摩擦而粘在……上面)on food. But over time, paint on the bags can chip and the bags can wear out. When this happens, lead can be released(释放).
The Tampa Tribune newspaper said certain bags sold at Publix and Winn-Dixie supermarkets had lead levels that were a concern to health officials. The affected bags were found in Florida. But Publix has more than 1,000 stores in Alabama, Florida, Georgia, Sough Carolina and Tennessee. Publix says that all of its bags are under current laws about lead content, but that they have asked the makers of the bags to reduce the lead levels in the product.
The bags with the highest levels of lead had fancy designs and many pictures. Plain reusable bags without decoration were found to contain little lead. Consumers worried about lead levels in reusable bags can change to cloth or string bags. Paper bags are also a good choice, since paper can be recycled(回收).
Since 2007, Publix supermarkets have sold more than 13 million reusable bags. The store says because shoppers have made the change to reusable bags, it has saved more than 1 billion paper and plastics bags. The shopping bags containing high levels of lead ______.
| A．have been reported by a newspaper |
| B．have been stopped by the government |
| C．have stopped people from using reusable bags |
| D．have caused serious health damage to customers |
From Schumer’s words we can learn that ______.
| A．reusable bags do little harm to kids’ health |
| B．people have shown much concern for the reusable bags |
| C．people will be informed of the facts about the reusable bags |
| D．people should refuse to buy things from supermarkets |
It can be inferred from the text that Publix might believe that the bags they sold are ______.
| A．dependable | B．convenient | C．harmful | D．popular |
Customers are advised to choose bags ______.
| A．with colorful designs | B．with fancy pictures |
| C．made of plastic | D．made of paper |
From the last paragraph we know that the use of reusable bags has ______.
| A．caused Publix a lot of trouble | B．saved Publix much money |
| C．cost Publix plenty of money | D．been proved a wrong decision |
Crazy is our new normal. With two teenage boys and three little boys, our family is restless—to the baseball field, track field(田径场)and piano lessons. Even though we’ve limited each boy’s activities and try our best to defend our family time, it seems that we’re in a constant state of flight.
“Embrace it. Roll with it,” my husband, Lonny, says, “It’s going to be like this for a while.”
He is right. It’s likely that life will continue to go forward before it slows down. But I remembered the still, quiet days that our family used to enjoy. I missed long walks through the park when we held the boys’ little hands. I longed for(渴望) lazy Saturday afternoons under the tree in our backyard. I wanted to slip back a few years, when busyness was the exception and not the rule.
One night, after a particularly full day and evening games, our family gathered on the porch(门廊)for ice cream. Two parents, two teens, and three small boys piled on one old swing and a couple of rocking chairs. We were together, in one place, for a small slice of time.
The moon was full. The Mississippi River, flowing past our home, was smooth as glass. I wrapped my own arms around the son who sat on my lap and breathed deeply to inhale his little-boy scent(气味)—dirt and sweat. My heart was still and content(满足的).
I realized that while crazy is our new normal happiness is as usual. They may look different from before, but they are still there—even if they’re in the form of a single moment on the porch. Maybe I just need the eyes to see.What does the author mainly talk about?
