Most American kids love Halloween treats, but a bucket of Halloween candy can be a dentist’s nightmare. Some parents try to get rid of half of the candy after their children go to bed, but dentists say parents also need to separate the good kinds of treats from the bad.
It is not exactly what a child eats that truly matters, but how much time it stays in his mouth. According to pediatric dentist Dr. Kaneta Lott, the most damaging stuff is something that is sticky or very hard and thus stays in the mouth for a long time. This is because we all have bacteria in our mouths. When we eat, the bacteria take our food as their food and produce an acid that destroys the surface of the teeth, causing cavities to form. The longer the food stays in the mouth, the more likely cavities will develop. Therefore, potato chips are worse than candy because they get stuck between teeth. For the same reason, raisins and crackers are not the best choice. Hard candies take a long time to consume and are also a bad choice for Halloween treats
If children really love candy, dentists recommend that they eat chocolate instead. Unlike hard candies, chocolate dissolves quickly in the mouth. Besides, chocolate contains tannins, which help to kill some of the bacteria in the mouth. But no matter what a child eats, brushing after each meal is still the best way to fight cavities.

We were standing at the top of a church tower. My father had brought me to this spot in a small town not far from our home in Rome. I wondered why.
“Look down, Elsa,” father said. I gathered all my courage and looked down. I saw the square in the center of the village. And I saw the crisscross (十字形) of twisting, turning streets leading to the square. “See, my dear,” father said gently. “There is more than one way to the square. Life is like that. If you can’t get to the place where you want to go by one road, try another.”
Now I understood why I was there. Earlier that day I had begged my mother to do something about the awful lunches that were served at school. But she refused because she could not believe the lunches were as bad as I said.
When I turned to father for help, he didn’t say anything. Instead, he brought me to this high tower to give me a lesson. By the time we reached home, I had a plan.
At school the next day, I secretly poured my lunch soup into a bottle and brought it home. Then I asked our cook to serve it to mother at dinner. The plan worked perfectly. She swallowed one spoonful and sputtered（喷溅出） “ The cook must have gone mad！” Quickly I told her what I had done, and Mother stated firmly that she would take up the matter of lunches at school the next day!
In the years that followed, I often remembered the lesson father taught me. I began to work as a fashion designer two years ago. I wouldn’t stop working until I tried every possible means to my goal. Father’s wise words always remind me that there is more than one way to the square.The author’s father took her to the top of a church tower to ____________.

People in the United States honor their parents with two special days: mother’s day, on the second Sunday in May, and Father’s day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.
These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery(墓地). On these days，families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries(面包师), telephone companies, and other stores do a lot of business during these holidays.Which of the following is NOT a reason for children to show love and respect for parents?
| A．Parents bring up children. |
| B．Parents give love and care to children. |
| C．Parents educate children to be good persons. |
| D．Parents pass away before children grow up. |
On Father’s Day, what do people often do?
| A．They wear carnations. |
| B．They have outdoor barbecues. |
| C．They attend religious services to honor parents. |
| D．They visit the cemetery. |
What do you think “florists” do? _________.
| A．They sell flowers. |
| B．They make and sell bread. |
| C．They offer enough room for having family parties. |
| D．They sell special gifts for Mother’s Day and Father’s Day. |

Walk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick. But if you had been around 15, 000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted (反应) to the cold, dry climates of the ice ages, but until now, no one has reached a satisfying answer.
Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier, will it still survive and continue to draw down CO2? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.
Unfortunately, getting into the Amazon rainforest and collecting information are very difficult. To study past climate, scientists need to look at fossilized pollen, kept in lake muds. Going back to the last ice age means drilling deep down into lake sediments (沉淀物) which requires specialized equipment and heavy machinery. There are very few roads and paths, or places to land helicopters and aero-planes. Rivers tend to the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled (未取样). So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.The underlined phrase “mopping up” in the second paragraph means ____.
| A．cleaning up | B．taking in |
| C．wiping out | D．giving out |
How will the Amazon rainforest react to future climate change?
| A．It’ll get drier and continue to remove CO2. |
| B．It’ll remain steamy, warm, damp and thick. |
| C．It’ll get warmer and then colder and drier. |
| D．There is no exact answer up to present. |
What’s the main idea of the last paragraph?
| A．It’s important to drill deep down into lake sediments to collect information. |
| B．It’s impossible to prove how climate changes in the Amazon rainforest. |
| C．It’s hard to collect information for studies of the past climate in the Amazon rainforest. |
| D．It’s necessary to have specialized equipment and machinery to study the past |
climate.The best title for this passage may probably be _____.
| A．Studies of the Amazon |
| B．Climates of the Amazon |
| C．Secrets of the Rainforests |
| D．Changes of the Rainforests |
