How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.
The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a doctor actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications(应用) on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters(怪物) among your teeth. “We try to make it smart but also fun,” Serval says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, for $99 to $199, depending on features. The U.S. is the first target market.
Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

There are five simple ways for your family to lead a healthy lifestyle and get back on track:
Get active each day
Regular physical activity is important for the healthy growth, development and well-being of children and young people.
They should get at least 60 minutes of physical activity every day, including activities that strengthen muscles and bones on at least 3 days of the week. Parents should be good rule models and have a positive attitude to being active.
Choose water as a drink
Water is the best way to satisfy your thirst – and it doesn‘t come with the added sugar found in fruit juices, soft drinks and other sweetened drinks. Reduced fat milk for children over two years of age is a nice drink. Give kids whole fruit to eat, rather than offering fruit juices that have a lot of sugar.
Eat more fruit and vegetables
Eating fruit and vegetables every day helps children and young people grow and develop, and can reduce the risk of many diseases. Eat two serves of fruit and five serves of vegetables every day. This varies for boys and girls at different ages.
Switch off the screen and get active
Children and young people should spend no more than two hours a day on small screen‘ entertainment. Break up long periods of use as often as possible. Plan some active indoor and outdoor games or activities for your children.
Eat fewer snacks and select healthier choices
Healthy snacks help children and young people meet their daily nutritional needs.
Snacks based on fruit and vegetables, reduced fat dairy products and whole grains are the healthiest choices. Avoid snacks that are high in sugar or fat –such as chips, cakes and chocolate – which can cause children to put on extra weight.
1.What should parents do to help their children to be active every day?
A.Set good examples themselves. B.Let children know the importance.
C.Give children enough time outdoors. D.Stop children from using the computer.
2.Which comes last when served to children?
A.Boiled water. B.Whole fruit.
C.Soft drinks. D.Reduced fat milk.

When I was growing up, I had an old neighbor named Doctor Gibbs. He didn't look like any doctor I'd ever known. He never shouted at us for playing in his yard, but was always very kind.
When Doctor Gibbs wasn't saving lives, he was planting trees. He had some interesting theories about planting trees. He believed in the principle: "No pains, no gains". He hardly watered his new trees, which greatly went against conventional (守旧的) wisdom. Once I asked why and he told me that watering plants spoiled them because it made them grow weaker. He said you had to make things hard for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how trees, if they were not watered, would grow deep roots in search of water. So, instead of watering his trees every morning, he'd beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention.
Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I'd watched him plant some twenty five years ago. They were all tall and strong.
I planted a couple of trees myself a few years ago. Two years of attending these trees meant they grew up weak. Whenever a cold wind blew, their branches trembled. Adversity seemed to benefit Doctor Gibb's trees in ways comfort and ease never could.
Every night before I go to bed, I check on my two sons. I often hope that their lives will be easy. But lately I've been thinking that it's time to change my idea. I know my children are going to meet with hard times. There's always a cold wind blowing somewhere. What we need to do is to hope for deep roots, so when the rains fall and the winds blow, we won't be torn apart.
1.With the trees planted, Doctor Gibbs often __________.
A.kept watering them every day B.paid very little attention to them
C.beat them to make them grow tall D.talked to them to get their attention
2.What does the underlined word “Adversity” in the 4th paragraph probably mean?
A.A happy moment. B.An important position.
C.A difficult situation. D.A dirty environment.
3.What does the author wish for his sons?
A.Meet people like Dr Gibbs in the future.
B.Have an easy, happy and comfortable life.
C.Have good luck, meeting no hardship at all.
D.Be able to stand the rain and wind in their lives.
4.Which of the following can be the best title of the passage?
A.Growing Roots B.Doctor Gibbs’ Trees
C.Watering Trees D.Helping My Sons

Getting up early has been regarded as a good habit since ancient times. Many years ago, people thought that if we went to bed early and got up early, we would be energetic the whole day. So, getting up early is of great importance to us all.
In fact, morning is the best time of a day. In the morning, the air is the freshest and people are usually in the best condition. Many of us may have the experiences that we memorize some things more quickly and correctly in the morning than at any other time of the day. And it is certain that we find it easier to understand what we learn in the morning. If we get up early and do some morning exercise or only take a short walk in the morning, without doubt we can build up our bodies and become much healthier. Also we will have enough time to make a plan and get ready for our work or study of the day if we get up early. For example, if everyone in the family gets up early, wives will have enough time to prepare the breakfast for the whole family; children will have enough time to catch the school bus, and husbands will never forget to change their dirty shirt. Everything will be in order. However, if we get up late, we’ll probably have to do everything in a hurry.
Let us remember getting up early is a good habit and try our best to keep it. Late risers may find it difficult to form the habit of getting up early. They have to make an effort to do so. If we stick to getting up early every day, we will certainly benefit a lot from it.

Tips for Cooking on a Tight Schedule
From my experience, there are three main reasons why people don't cook more often：ability, money, and time. 1.Money is a topic I'll save for another day. So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen. Here are three tips for great cooking on a tight schedule：
1. Think ahead. The moments when I think cooking is a pain are when I'm already hungry and there's nothing ready to eat. So think ahead of the coming week. When will you have time to cook? Do you have the right materials already? 2.
2. Make your time worth it. When you do find time to cook a meal, make the most of it and save yourself time later on. Are you making one loaf of bread? 3. It takes around the same amount of time to make more of something. So save yourself the effort for a future meal.
3. 4.This may surprise you, but one of the best tools for making cooking worth your time is experimentation. It gives you the chance to hit upon new ideas and recipes that can work well with your appetite and schedule. The more you learn and the more you try, the more ability you have to take control of your food and your schedule.
Hopefully that gives you a good start. 5.And don't let a busy schedule discourage you from making some great changes in the way you eat and live!
A.Try new things.
B.Ability is easily improved.
C.Make three or four instead.
D.Understand your food better.
E.Cooking is a burden for many people.
F.Let cooking and living simply be a joy rather than a burden.
G.A little time planning ahead can save a lot of work later on.
