    How healthy are your teeth? Are you lazy about brushing them? Now a new electric toothbrush (电动牙刷) can help you know how long and how well you brush.

    The Kolibree toothbrush was shown at the International Consumer Electronics Show in Las Vegas this week. It shows how it is moved and that it can send the information to an Android phone or iPhone.

    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 dentist watch you brushing," says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other APPs on your phone, so developers could, for example, make a game controlled (控制) by your toothbrush. You could get points for beating monsters (怪物) while brushing your teeth. "We try to make it smart but also fun," Serval says.

    Why did Serval invent the toothbrush? He says this idea is from his experience as a father. Every day, he asked his kids if they brushed their teeth after he came home from work. They said "yes," but Serval always found 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 be on sale this summer, for $99 to $199. The U.S. is the first market.

(1)、The Kolibree toothbrush can not _______.
A、help the user find his phone B、help the user know how well he brushes C、teach the user to brush right D、send the teeth information to an iPhone
(2)、What can you know from Serval's underlined words in Paragraph 3? 
A、You will find it great to see a dentist.  B、You should see your dentist every day. C、You'd like a dentist to watch you brush.   D、The Kolibree toothbrush is just like a dentist.
(3)、Which of the following is TRUE according to the passage?
A、Serval invented the toothbrush to make money at first. B、The Kolibree toothbrush is smart but not fun for kids. C、Serval's children didn't want to brush their teeth at home. D、People can buy the Kolibree at low prices in China this summer.
(4)、The best title of this passage may be "_______".
A、A Kind Dentist B、A New Toothbrush C、How to Brush D、Why to Brush
举一反三

    You might not pay much attention to whether the things you say on WeChat and other online messaging apps are recorded. But a regulation (规定) that went into effect on May 1 will make everything you say online usable against you in a court of law (法庭).

    According to the Supreme People's Court's regulation, text messages, emails, and content posted on websites or instant (即时的) messaging platforms can be used as evidence (证据) in civil lawsuits (民事诉讼).

    The idea of digital evidence was first introduced as part of China's Civil Procedure Law in 2012. However, the recent regulation has made it clearer.

    "This is the first time the Supreme People's Court has clarified (阐明) the scope of digital evidence, especially on social media platforms and instant messaging services," Li Ya, a lawyer in Beijing, told China Daily.

   The regulation was introduced to keep up with changes in social development. Social media activity has become a part of most people's lives. Therefore, digital evidence is playing an increasingly important role in civil and criminal lawsuits.

    According to the regulation, if people plan to use digital evidence in a lawsuit, they have to first prove that they use the app or website that the evidence comes from. Second, they must provide an original (原始的) and complete record of the evidence. For example, if you lend somebody money through WeChat, you must keep the original transfer (转账) records and conversations on the app.

    However, there are still questions about the regulation. Some point out that the regulation will not necessarily help in every case. "How to make sure a microblog was actually posted by the micro blogger is a challenge," Li said.

    Grandparents are respected in many human societies. But telling stories about old times and overfeeding grandchildren seem like human qualities. Are these classic grandparent behaviors really limited to humans?

Do any animals know their grandparents the way people do?

For most species on Earth, the answer is certainly " No" . " Usually, there aren't grandparents around anymore when an animal is born,"  said Mirkka Lahdenpera, a biologist at the University of Turku in Finland. " Even if an animal's life span does overlap (重叠) with its grandparents', most species spread out to avoid competing for resources, so the chance of running into a grandparent is slim." 

But there are a few clear exceptions, primarily among mammals (哺乳动物) that live in close social groups. In troops of langur monkeys in India, older females lived together with their daughters and grandchildren. The grandmother langurs defend the group's babies against attacks and even give their own grandchildren special treatment.

Many whale species, too, travel in family groups that include both grandmothers and grandchildren.

Elephant herds are also famously matriarchal. They are led by a grandmother, who can live to around 80 years old, and are generally made up of her daughters and their young. The females in a herd form close bonds and work together to raise their young.

Lahdenper found that the babies of young mothers were eight times more likely to survive if their grandmothers lived near them than if they didn't. When the young mothers were older and more experienced at raising babies, this beneficial grandmother effect disappeared even if the actual grandmothers were still around.

Indeed, most evidence for the benefits of grand parenting comes from mammals. But in 2010, researchers found that in troops of insects called gall-forming aphids, older females defend their relatives after they've stopped reproducing (繁殖).

And what about grandfathers? Studies of humans in recent decades have shown that a living grandfather can improve a person's mental health and other indicators of well-being. But there's no evidence of that in the animal kingdom. Male animals rarely socialize with their own children, let alone any grandchildren.

①Eating good food and getting proper exercise are important to stay healthy. Getting enough sleep is important, too. Experts say that teenagers between the ages of 15 and 20 need 8 to 10 hours of sleep each night. 

②Your body needs to take a rest from all the activities it has done during the day. Your brain needs a rest, too. You are likely to get sick easier without enough sleep. 

③You have a "24-hour clock" inside your body that tells you when to be awake and when to go to sleep.  ▲  Blue light that comes from the Sun tells your brain to keep you awake during the day. When there is no blue light at night, the brain tells the body that it's time for sleep. 

④There are many things that stop the brain from telling your body when it's time to sleep. One of these is blue light at night. Today, people spend a lot of time watching television or looking at screens on computers or smart phones. These devices (装置) give off blue light. If you look at them at night, the blue light can trick your body into thinking it's daytime. Then it is more difficult to go to sleep.

⑤What should you do to get good sleep? Experts say that you shouldn't look at screens that give off blue light for at least one hour before going to sleep. 

⑥ Do not watch TV or use anything with a computer screen in bed. If you need to do something to fall asleep, it is better to read a book. Also, keep your bedroom as dark as you can. This will help you sleep well. 

Fun Fact

Going to bed at the same time every night helps you get used to a schedule so you will be ready to sleep at the proper time.
