Bad teeth can be painful -- and worse. They can even be deadly. Infections (感染) of the gums (牙龈) and the teeth can cause bacteria (细菌) to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk.

For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿保健) he needed. He was twelve years old.

Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.

But dentists say a baby's gums 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, only give the child water.

When baby 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.

The use of fluoride (氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (珐琅质) , the hard surface on teeth, to help prevent holes from forming.

1.Which of the following can be used as the title of the passage?

A．Concerns for Healthy Teeth of the Young

B．Causes of Teeth Problem

C．Importance of Healthy Teeth of All

D．Solutions to Teeth Problem

2.What's the main idea of paragraph 4 and 5?

A．How to develop babies' teeth.              B．How to keep babies' teeth clean

C．Why to protect babies' teeth               D．Why to keep babies' teeth clean

3.The passage indicates that ______.

A．Enamel is most widely used to protect teeth in the world

B．Breast milk can cure babies' bad teeth

C．Bad teeth may affect the health of adults and the young

D．Babies' teeth should be brushed once per day

4.The writer uses the boy's death as an example to show that ______.

A．not only adults but the young may suffer from teeth problem

B．the doctors should be responsible for the case

It can be hard to meet people from another culture. From the beginning, people may send the wrong signal（信号）. Or they may pay no attention to signals from another person who is trying to develop a relationship.

Different cultures emphasize （强调）the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in “small talk”, usually over a glass of tea, before they do any job. In many European countries--like the UK or France—people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.

Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.

Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment（多元文化环境）will offer a wonderful chance for us to learn from each other.

1.In some countries, eating together at restaurants may make it easier for people to ________.

A. keep each other company            B. share the same Culture

C. get to know each other              D. develop closer relations

2.The author mentions his experience in Thailand to show that _________.

A. even talk and silence can be culturally different

B. too many words are of no use

3.According to the text, how can people from different cultures understand each other better?

A. By sharing different ways of life.

B. By recognizing different values.

C. By accepting different habits.

D. By speaking each other’s languages.

4.What would be the best title for the text?

A. Multicultural Environment.           B. How to Understand Each Other.

C. Cross-Cultural Differences.           D. How to Build Up a Relationship.

It can be hard to encourage families of preschoolers to turn off the TV，but there are plenty of high­quality shows that promote learning and positive relationships rather than violence，researchers noted.

“Although clearly kids watch too much，what’s more worrying is that they watch poor quality shows，” said Dr Christakis，the lead researcher on the new study from the University of Washington in Seattle.His former survey of parents of three­to five­year­old children showed the kids often watched violent cartoons and movies that are “totally inappropriate”．

For their study，he and his colleagues randomly divide 565 preschoolers into two groups.In one group，parents recorded notes about kids’ normal TV viewing，without receiving any guidelines to reduce or change those habits.In the other group，researchers made visits and calls and sent monthly newsletters encouraging parents to replace violent TV with educational programming.After six and 12 months，parents reported their kid’s angry，aggressive or anxious behaviors on a questionnaire.At both time points，children in the TV intervention (干预) program had slightly fewer problems than those in the comparison group.Boys in low­income families seemed to benefit most from the change in programming，the researchers found.

“The point is，this is something that is as effective as other things we do to try to guide behavior in children，and it’s fairly simple，” Christakis said.

Another study published in Pediatrics found the more TV kids and teens watched，the more likely they were to have a crime or other problems in society.Children may imitate violence they see—or more time in front of the TV could simply mean less communication with peers and families，and worse performance in school.

The American Academy of Pediatrics recommends kids watch no more than one to two hours of high­quality programming each day.Researchers agreed parents should be mindful of what exactly their young kids are watching on TV as well.“It’s　 not just about turning the TV off，it’s about changing the channel，” Christakis said.

1.What is the positive effect of high­quality TV shows on kids?

A．Good learning results and relationships.

B．Being affected by violence.

C．Spending less time on TV programming.

D．Encouraging them to turn on the TV.

2.For Christakis，what is more concerning?

A．Kids watching too much TV.

B．TV shows being of poor quality.

C．Kids watching too many cartoons.

D．Parents receiving no guidelines.

3.We can learn from the survey mentioned in Para.3 that________.

A．Children don’t like being disturbed while watching TV

B．Preschoolers seems to like newsletters more than TV

C．Poor children prefer to watch educational programming

D．Kids watching high­quality programs have fewer problems

4.Christakis thought the effect of educational programming on children’s behaviour was________.

A．unclear　　 　    B．slight　　

C．obvious 　    D．great

5.According to the researchers，________.

A．getting preschoolers away from TV is difficult

When a friend approaches you in the heat of a moment, it can be hard to know what to say. There’ no blanket approach for every person through every crisis (危急), but a few guidelines could help you offer the best support.

Friends going through a crisis often just need someone to talk to and explore their feelings with, but the trick is to listen without sounding like you’re judging. Reorganize “why” questions, which can imply you’re questioning their judgment, but ‘how’ and ‘what’ questions, and ‘who’ and ‘when’ seem caring and sincere.

Open-ended questions that can’t be answered with a ‘yes’ or ‘no’ will also help friends dig into their deepest feelings during a crisis. While your loved ones talk through their replies, practice active listening by focusing on their answers. After all, your friends probably just need someone to listen and prove them, rather than hearing you offer potentially unhelpful advice.

When you do respond，avoid telling friends in crisis how they “should” be feeling. “ ‘Should’ is not a valid term, saying it’s not OK for you to feel these societally ‘weak’ feelings,” says Michelle Kuchuk, director of training for Crisis Text Line. “If you’re only hearing ‘you should feel great’, you’re never going to speak again or get that weight off your chest if you think other people will judge you.”

On the other hand, tying those positive feelings to a specific action can feel more sincere. If friends hear “you’re so strong” without an example to back it up, they might never believe it. But if they’ve been explaining how hard it was to talk to someone else, praise them for taking that brave step.

Finally, it’s more important for a friend to know you’re there for support than stressing about saying the right thing during a crisis. Just be a friend and really listen to that person, not with your own agenda but “what is this person really going through?”

1.Who is this passage intended for?

A. People to be consultants.　　 B. People in need of support.

C. People going through a crisis.　　 D. People supporting friends in crisis.

2.What is your most suitable question to ask one talking to you?

A. Who did that1?　　 B. When did you start it?

C. How did you feel about it1?　　 D. Why did you feel that way?

3.What does the underlined part mean in the 4th paragraph?

A. Tell the truth out.　　 B. Relieve their pressure.

C. Keep everything secret.　　 D. Leave your baggage behind.

4.What is suggested to respond to your friends’ talking?

A. Preparing your questions beforehand.

With schools close in the UK during the COVID-19 outbreak, most children must now be homeschooled. Parents have found themselves not only having to balance work and having the children at home but also having to try and teach them. How can you keep your children focused while learning?

Nicola Anderson--Head of Customer Support at the UK’s leading online tutoring service MyTutor, provides new, up-to-date tips to hearten parents at this difficult time and advises how they can structure their children’s days.

One is to keep to a regular timetable so it still feels like your child is taking part in the school day. Ms Anderson said: “Children of all ages do well on routine and boundaries; schools provide this in abundance and it will most children feel secure and happy if they can follow a similar timetable for their homeschooling.”

Another tip is to create an environment which is favorable to learning. She said:” The environment should be free from distractions and ideally near to an open window, to provide them with appropriate levels of fresh air and natural light. Some children find it comfortable and helpful to have quiet, instrumental music playing in the background to help them to focus, but this isn’t for everyone.”

Using technology to help with your child’s learning is also advised. Many schools are offering online classes and resources to help and companies are reducing or even not charging their fees during this time.

It is also important to keep physical exercise as a part of your routine. Joe Wicks, otherwise known as The Body Coach, has been keeping kids healthy with daily 10 minute workouts for children on his Youtube channel. Ms Anderson said:” It can be anything from running around the garden, walking the dog, a game of football or dancing around your living room!”

1.Who is the text intended for?

A.Student. B.Teachers.

C.Coaches. D.Parents.

2.What does the underlined word“this" in paragraph 3 refer to?

A.Homeschooling. B.Tutoring service.

C.A regular timetable. D.Difficult time:

3.What may Nicola Anderson agree?

A.To allow children to adjust schedule freely.

B.To offer children peaceful study environment.

C.To recommend high-tech to online schools.

D.To combine routine with kids' mental heath.

4.What is the text mainly about?

A.How to improve homeschooling efficiency.

B.How to obtain online learning resources.

C.How to study attentively at home.

D.How to design a proper schedule.
