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.

(2013·高考新課標全國卷Ⅱ，C)Given that many people’s moods (情緒)are regulated by the chemical action of chocolate，it was probably only a matter of time before somebody made the chocolate shop similar to a drugstore of Chinese medicine.Looking like a setting from the film Charlie&the Chocolate Factory，Singapore’s Chocolate Research Facility (CRF) has over 100 varieties of chocolates.Its founder is Chris Lee who grew up at his parents’ corner store with one hand almost always in the jar of sweets.
If the CRF seems to be a smart idea，that’s because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi’s and Sony.That idea surely results in the imagination at work when it comes to making different flavored (味道) chocolates.
The CRF’s produce is “green ”，made within the country and divided into 10 lines，with the Alcohol Series being the most popular.The Exotic Series－with Sichuan pepper，red bean (豆)，cheese and other flavors－also does well and is fun to taste.And for chocolate_snobs，who think that they have a better knowledge of chocolate than others，the Connoisseur Series uses cocoa beans from Togo，Cuba，Venezuela，and Ghana，among others.
小題1:What is good about chocolate?

A．It serves as a suitable gift.

B．It works as an effective medicine.

C．It helps improve the state of mind.

D．It strengthens business relations.

小題2:Why is Chris Lee able to develop his idea of the CRF?

D．He has a lot of marketing experience.

小題3:Which line of the CRF produce sells best?

B．The Exotic Series.

C．The Alcohol Series.

D．The Sichuan Series.

Researchers conducting a study of hospital stays for over two hundred and eighty six thousand older folks found something interesting in their data.
The number of hospitalizations for heart disease and stroke went down significantly among a certain group of people at a certain time of year. What folks, and what time of year, you ask? Flu season and the lucky people were the ones who got flu shots(流感疫苗).
It’s generally recommended that people over fifty get their flu shots every year. Influenza(流行性感冒) is no small thing. it’s responsible for around thirty six thousand deaths a year in the U. S. alone. Getting the shots also cuts down on the chances of getting pneumonia(肺炎), which is especially dangerous in seniors.

So what's the connection between getting a flu shot and having a stronger heart? It isn’t yet known.
Researchers speculate that the flu virus itself may do damage to blood vessels(血管), possibly making clots(血塊)more likely. Blood clots in the heart can cause heart attacks, and blood clots in the brain can cause strokes.

Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests．That was the finding of a study of teenage males in Norway．Now，other research shows that physical activity may help students do better in their classes .
The research comes as educators in some countries are reducing time for activities like physical education．They are using the time instead for academic subjects like maths and reading．The studies appeared between 2007 and 2013．They included more than 55，000 children，aged 6 to 18．
Amika Singh：“Based on the results of our study，we can conclude that being physically active is beneficial for academic performance. There are，first，Physiological explanations，like more blood flow, and so more oxygen to the brain．Being physically active means there are more hormones(荷爾蒙)produced like endorphins(內啡肽)．And endorphins make your stress level lower and your mood improved, which means you also perform better.”
Also，students involved in organized sports learn rules and how to follow them．This could improve their classroom behavior and help them keep their mind on their work．
The study leaves some questions unanswered，however．Ms．Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement．This is because of differences among the studies .
Also．they were mostly observational studies．An observational study is where researchers do not do controlled comparisons．They only describe what they observe．So they might observe a link that students who are more active often have better grades．But that does not necessarily mean being active was the cause of those higher grades．
The researchers said they found only two high - quality studies．They called for more high-
quality studies to confirm their findings．They also pointed out that “outcomes for other parts of the world may be quite different. ”
Still，the general finding was that physically active kids are more likely to do better in school．Ms．Singh says schools should consider that finding before they cut physical education programs．Her paper on “Physical Activity and Performance at School”is published in the Archives of Pediatric and Adolescent Medicine．
小題1:The passage mainly tells us that ＿＿＿＿

A．a research on physical education has been done by the researchers

B．there exists a possibility that physical activity leads to higher grades

C．the amount or kind of activity directly affects academic level

D．the research shows that the children aged 6 to 1 8 don't do sports

小題2:Which of the following is TRUE?

A．Being mentally active is good for academic subjects．

B．The more hormones you have，the more stressed you will get．

C．They have found many high-quality studies to prove the research．

D．The educators in the research think studies，not exercise，mean much to students．

小題3:The underlined sentence in Paragraph 7 probably means ＿＿＿＿.

A．good marks result from high-quality study

B．findings probably vary in different areas

C．physical activity will spread all over the world

D．academic performance depends on the surroundings

小題4:What's the purpose of writing the passage?

A．To call our attention to the sports at school．

B．To introduce all types of physical activities．

C．To represent the academic performance．

D．To improve students' health ．

Many people don't realize the importance of music education in the schools today．A new study showed, however, music education is extremely important．
In college, music education is one of the largest programs．Teachers have to learn general education materials and techniques． They must learn to play every instrument; they must learn music history and music theory; they must learn instrument repair and teaching methods; they must learn conducting and so much more．At the same time, much of our culture and tradition is absorbed in music．
Music plays a very important role in our education．
Music helps with math and science． Students learn to count, and how to multiply and divide．Students also use science to help them discover what sounds good together and what doesn't．Students also need science to understand something called the “overtone series", which is about how music is produced by vibration（顫動）and why．
Students learn a lot about languages through music．Many songs are written in other languages, including ancient ones．Students must learn to translate these works to understand what they are singing about． A song is likely to be a famous short work set to music; so students are exposed to that very often while singing．
Students learn a huge amount of cooperation （協作）of body parts through music, so parts of the body can work better together．Students must use motor（肌肉運動的）skills in order to play an instrument．Singers and wind（管樂器）players must learn breath control and be in good shape to play．
Students learn about art． Some famous pieces were written about important pieces of art, and students learn about the artists and styles as they're playing the music．
Music education also brings higher thinking to our children．It allows them to think about complex patterns．Students have to be aware of what every other musician does at every time．In that way, it develops cooperation, as well．They tend to develop more ability for learning．
As one can see, music is very important to education．
小題1:According to the passage, learning music in college will be quite ．

A．easy

B．stressful

C．attractive

D．useless

小題2:As to the benefits from music, which of the following is NOT included in the passage?

Do you like seahorses? What do you know about them?
The seahorse is actually not a horse but a fish, and much smaller than any regular horse. In general, a seahorse is about an inch long. It is a beautiful fish that likes warm waters, swims upright (直立的), and looks a little like a chess piece.
Seahorses are an unusual kind of animal because the males (雄性) give birth to babies. Mating (交配) takes place in cooler waters on spring and summer nights with a full moon. The females (雌性) put their eggs into the bodies of the males, and the males give birth to baby seahorses.
The seahorse can use each eye separately, which allows it to search for food without moving the rest of its body. Seahorses situate themselves near deep, fast-running channels rich in plankton, a kind of life on which they feed. They can catch food from an inch and a half away. Seahorses can change from gray or black to yellow or purple within seconds to fit in with their surroundings, and in this way escape from most of their enemies.
One of the surprising facts about seahorses for most people is that they are vertebrates (脊椎動物). They can turn and curl freely, and like to swim in pairs connected by their tails. Their tails are powerful, and they can use them to grasp the surrounding seaweed (海藻) to keep themselves from being swept away. So seahorses are usually found in warm water filled with seaweed.
Now that you know all these facts about seahorses, don’t you find them more interesting?
小題1:We can learn from the passage that seahorses _______.

A．are beautiful, and live on seaweed

B．are as big as regular horses

C．live near deep channels

D．like to be alone

小題2:The third paragraph tells us that _______.

A．male seahorses lay eggs

B．seahorses mate in spring or autumn

C．male seahorses give birth to babies

D．seahorses mate in warmer waters at night

小題3:Which of the following protects seahorses from being eaten by their enemies?

A．Their fast speed of swimming.

B．Their ability to change colours.

C．Their unique eyes.

D．Their strong tails.

小題4:Which of the following can replace the underlined word "grasp"?

A．Eat.

B．Hold.

C．Make.

D．Handle.

A good teacher is many things to many people. In my own experience, the people I respect the most and think about the most are the teachers who demanded (要求) the most discipline (紀律) from their students.
I miss one teacher in particular that I had in high school. I think she was a good teacher because she was a very strict person. I remember very vividly (清晰地) a sign over her classroom door. It was a simple sign that said, “Laboratory—in this room the first five letters of the word was emphasized (強調), not the last seven.” In other words, I guess, labor for her was more important than oratory, which means making speeches.
She prepared her work very carefully and demanded us to do the same. We got lots of homework from her. Once she had broken her arm, and everybody in the class thought that maybe the homework load would be reduced, but it continued just the same. She checked our work by stamping her name at the bottom of the papers to show that she had read them.
I think sometimes teachers who demand the most are liked the least. But as time goes by, this discipline really seems to benefit (有益于) the students.
小題1:Which of the following is considered a good teacher by the writer?

A．A patient teacher.	B．An honest teacher.
C．A strict teacher.	D．A hard-working teacher.

小題2:The teacher put up the sign over her classroom door ___.

A．to remind the students that this room was a laboratory

B．to advise the students to follow the disciplines

C．to warn the students not to be careless

D．to tell the students to work hard in the classroom

小題3:When the teacher’s arm was broken, she ___.

A．gave her students the usual amount of homework

B．gave her students less homework

C．asked her students to check the homework themselves

D．gave her students more homework

小題4:What’s the writer’s opinion of discipline?

A．It makes the students dislike their teachers.

B．It does good to the students in the long run.

C．It’s too much for young children.

D．It does more harm than good to the students.

【1】People study their family history for different reasons. For some, genealogy(家譜學) is important to their religion（宗教信仰）. Other people who get involved in genealogy may want to confirm （證實）stories they heard about a family member. Some people say their interest in genealogy came from an eight-part series on television called Roots.
