Bad teeth may be painful and it’s getting worse without treatment. They can even ruin your life. Illness of the teeth can find its way into the blood system. This can increase the chances of a heart disease or other illnesses.
Experts say good care for teeth should start at birth. Mothers’ milk is the best food for the healthy development of teeth.
But dentists say a baby’s mouth and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, give him only water.
When baby’s teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. Young children often eat toothpaste (牙膏) when they brush, so they should be carefully watched when they brush their teeth.
Parents often ask what effect thumb sucking (咬手指) might have on their baby’s teeth. Experts generally agree that this is fine early in life. Most children stop sucking their thumbs by the age of four. If it continues, parents should talk to their children’s dentist or doctor.
Dentists say children should have their first dental visit by the time they are one year old. They say babies should be examined when their first teeth appear usually at around six months.
【小題1】Why should people pay attention to teeth problems?
| A．They can cause other illnesses. |
| B．They will bring bad luck. |
| C．They will bring the family much trouble. |
| D．They usually last a long time. |
| A．he begins to speak | B．he has his first tooth |
| C．he was born | D．he is fed with bottle milk |
| A．toothache | B．parents’ trouble | C．thumb sucking | D．experts’ advice |

About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred if affected in this matter. Perhaps, after all, it is safer to be driven by a woman.
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can’t tell the differences between blue and green. In rare cases an unlucky man sees everything in shades of green--- a strange world in deed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions very small things called “cones”. These help us see in a bright day and tell the differences between colors. There are also millions of “rods”, but these are used for seeing when it is nearly dark. They show us shapes(形狀) but not color. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects but a blue lamp will. In similar way human being also have favorite colors. Yet we are lucky. With the aid of cones in our eyes we can see many beautiful colors by day and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
【小題1】The passage is mainly about ______.
| A．color and its surprising effects on drivers |
| B．women being luckier than man in that fewer of them are color blind |
| C．danger caused by color blindness |
| D．color blindness and how our eyes tell different colors and shapes |
| A．tell different colors | B．see in weak light |
| C．tell different shapes | D．tell orange from yellow |
| A．Women are more careful. |
| B．There are fewer color blind women. |
| C．Women are fonder of driving than men. |
| D．Women are weaker but quicker in thinking. |
| A．Not all of them have the same problem in recognizing colors. |
| B．None of them can see deep red but all can tell blue from green. |
| C．None of them can tell blue from green but all can see deep red. |
| D．All of them are lucky enough to see everything in shades of green. |

400-year-old plants from the Little Ice Age were brought back to life, which could help us understand how the Earth will deal with climate change.
Moss(蘚類植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.
Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(莖). Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts.
Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before.
While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte(苔蘚類植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.
Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that blew my mind. When we think of thick areas of ice covering the landscape, we’ve always thought that plants have to come from refugia(瀕絕生物保護(hù)區(qū)), never considering that land plants come from underneath a glacier. It’s a whole world of what’s coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world; we don’t know it all.”
Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age. Dr La Farge’s team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water.
The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.
However, Dr La Farge was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings（論文集）of the National Academy of Sciences.
【小題1】Dr La Farge’s research is of great importance to ________.
| A．knowing what the plants during the Little Ice Age were like |
| B．understanding how ecosystems recover from glaciers. |
| C．regrowing many species that have been destroyed before. |
| D．figuring out the effects of melting ice caps on moss. |

| A．lives better in small groups |
| B．is very active in hot weather |
| C．is strong enough to survive coldness |
| D．is chosen from Canadian refugia |
| A．Bryophyte ecology is greatly affected by climate change. |
| B．400-year-old moss’s survival is a mystery to solve. |
| C．Moss in ancient times was discovered in Canada. |
| D．400-year-old plants were brought back to life. |

The relationship between humans and animals has always been complex. Some cultures have developed entire belief systems around favored animals. Even in cultures with less formal belief systems, connections between people and animals still lead to commonly accepted opinions about animals.
These belief systems usually develop around the animals that interact (互動) with humans most frequently. Therefore, it should not be surprising that so many stories surround the most common of animals: rats. Rats live side by side with humans all over the world and regularly interact with people. Human-rat coexistence may be common all around the world, but different cultures respond to that closeness in different ways.
In the United States and Europe, one typical attitude is that the rat is a pest. This could be due to the common belief that rats spread disease. Actually, they don’t, at least not directly, but many people don’t know that. The Pied Piper of Hamlin, a well-known children’s story, is one example of how rats have been described in Western literature: in that story, rats cause such a problem that a town has to hire a piper to call them all away.
In many Latin American countries, the rat is described in a very different way. The story of the tooth fairy (a fairy believed by children to leave money while they sleep in exchange for a tooth that has come out) is common all over the world, but in Latin America, the “fairy” is a rat! Rats do have very strong teeth, which could explain the association. Clearly, this shows another attitude toward rats that is much more positive.
Yet another attitude toward the rat can be seen in the Chinese Zodiac (生肖). The Rat is one of the animals of the Zodiac. Like the other zodiac animals, the Rat is neither entirely good nor entirely bad. It’s described as clever and friendly, but also tricky and not entirely honest. That may be the most accurate description of the rat so far. Whether you like rats or not, it’s hard to deny their reputation for cleverness.
As many people are discovering these days, rats can even make excellent pets, so long as you remember to close the cage carefully!
【小題1】What does the passage mainly talk about?
| A．A trend of keeping rats as pets. |
| B．How different cultures look at rats. |
| C．How humans get along with animals. |
| D．Favored animals in different cultures. |
| A．unpleasant | B．honest | C．smart | D．unusual |
| A．the tooth fairy is lovely |
| B．rats look very frightening |
| C．rats are welcome in Latin American countries |
| D．the story of the tooth fairy is common all over the world |
| A．don’t spread disease |
| B．should be treated as pests |
| C．a(chǎn)re fairly described in the Chinese Zodiac |

Monkeys , face to face
DISCOVER magazine once reported on a curious event in the woods : a group of monkeys applied mud (泥) to their faces in order to keep away insects , but when they were done they seemed to have lost their ability to recognize each other ---two monkeys that were supposed to be friends even started fighting.
“Faces are really important to how monkeys and apes (猿)can tell one another apart,” explained Michael Alfaro, a biologist at University of California, Los Angeles (UCLA), to the New York -based International Science Times . This is quite different from many other animals , which depend heavily on smells.
Since faces play such a crucial part in the social lives of monkeys , could this explain why certain monkey species have such colorful faces while others have simpler, plainer ones ?
To test this theory , a group of researchers from UCLA studied 139 monkey species , mainly from Asia and Africa, and analyzed hundreds of headshot (頭像）photos of those monkeys from their databases.
It was found that species that live in larger groups have faces with more complex color patterns than those that live in smaller groups. According to Live Science, researchers believe that this is nature’s way of making it easier for monkeys to recognize each other since those living in larger groups have to distinguish between a greater number of faces.
This is actually not that hard to understand . Just imagine if there were 10 people standing in front of you, all wearing white clothes. It would be much more difficult to tell them apart than if they wore clothes with colorful patterns. However, if there were only two people that you had to identify, a lack of color wouldn’t be much of a problem.
Apart from the need to recognize group members , researchers found that geography and environment also affect monkeys’ facial colors. Species that live closer to the equator in thick, humid (潮濕的）forests were found to have darker faces than those who live in dry areas further away from the equator. This is because darker faces help camouflage (偽裝）the monkeys in the woods so that they go unnoticed by predators (捕食者）.
【小題1】We can learn from the article that monkeys mainly recognize each other by their __.
| A．Smells | B．Facial appearances | C．body shapes | D．Voices |
| A．Larger monkeys have more complex face color patterns. |
| B．Monkeys with colorful face patterns usually take higher social positions within groups. |
| C．Monkeys living in smaller groups usually have simpler, plainer face patterns. |
| D．Colorful face patterns keep monkeys safe from predators. |
| A．The social lives of monkeys. |
| B．How monkeys tell each other apart. |
| C．A comparison between the face patterns of monkeys and those of human beings. |
| D．The different factors that determine monkeys’ face patterns. |

“If you want to see a thing well, reach out and touch it!”
That may seem a strange thing to say. But touching things can help you to see them better.
Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don't touch!”means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!
Most museums are just for looking. But today some museums have some things to touch. Their signs say, “Do touch!” There you can feel everything on show.
If you want to see better, reach out and touch. Then you will really see!
【小題1】By touching things, .
| A．you will have a strange feeling |
| B．you will learn how to reach out your hand |
| C．you can learn more about them |

Astronomers have captured(捕獲) the first direct image of a planet being born.
Adam Kraus, of the University of Hawaii’s Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth.
The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago.
Called LkCa 15b, it’s the youngest planet ever observed. The previous record holder was about five times older.
Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA’s Goddard Space Flight Center in Maryland.
Observing planets while they’re forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away.
Planets can change orbits(軌道) after forming, so it’s difficult to answer such questions by studying older planets.
“These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now,” Kraus said.
Scientists hadn’t been able to see such young planets before because the stars they’re circling around outshine(光亮強過) them. Kraus and Ireland used two techniques to overcome this problem.[來源:學(xué)+科+網(wǎng)]
One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion(扭曲) created by the Earth’s atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star.
The star LkCa 15—the planet is named after its star—was the team’s second target. They immediately knew they were seeing something new, so they plan to gather more data on the star.
【小題1】The research on younger planets helps scientists _____________.
| A．study why planets change orbits after forming |
| B．understand how planets move around their stars |
| C．a(chǎn)nswer questions about the age of stars and planets |
| D．know the relationship between planets and their stars |
| A．Their stars are brighter than them.. | B．They are very far from the earth. |
| C．They are generally too small. | D．They rarely form. |
| A．have been working in the same university |
| B．observed the planet on a volcano in Hawaii |
| C．used two new methods in the observation |
| D．cut holes in the mirrors when observing |
| A．Youngest planet seen as it’s forming. |
| B．Planet 450 light years away discovered. |
| C．World’s first direct image of a planet taken. |

Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the colder months. Squirrels (松鼠), for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.
They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut (黑胡桃) trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.
Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.
Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.
The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.
【小題1】The study done by Rob Swihart and Jake Goheen is to ________ .
| A．find out the living conditions for squirrels |
| B．do something to get rid of squirrels |
| C．learn squirrels’ influence on black walnut trees |
| D．save the forests in the American state of Indiana |
| A．the way they gather the walnut |
| B．the place they store the walnuts |
| C．the time they have winter sleep |
| D．the place they have winter sleep |
| A．nuts above the ground will not develop into plants |
| B．red squirrels eat more nuts than gray squirrels |
| C．gray squirrels and red squirrels will have severe fights |
| D．seeds can be traps for other animals in the forest |
| A．Gray squirrels do more harm to the forest than red squirrels. |
| B．Red squirrels and gray squirrels have helped the spread of walnut trees. |
| C．The cleaning of forest land benefits red squirrels directly. |
| D．The black walnut is equally attractive to both gray and red squirrels. |
