All about the human life cycle

The word cycle makes us think about things that go round and round,like the wheels on your bike or scooter.Today we are going to be looking at life cycles.

What is a life cycle?

The life cycle describes the life of a living being from when it is born to when it grows up, including all those changes during this time.

Different stages of being a human

1. Baby

The human life cycle starts with the baby stage. When babies are born, they can't do anything for themselves.

Up until they are six months old, babies don't eat normal food. They only drink milk. It isn't like the milk you might put on your cereal. It has all the things a baby needs to grow properly. We call it formula.

Babies need lots of sleep. They don't usually sleep all the way through the night but they will often sleep during the day as well.

Babies can't talk- when something is wrong，they will let people know by crying.

2. Toddler

Just like the name suggests, the toddler stage is when a child is starting to toddle, which means wobbly walking. The toddler stages are from ages 1 to 3.

As well as learning to walk, Toddlers go through lots of other changes.

Their teeth start to grow.

They start learning to talk.

Toddlers start learning to eat a lot of food and to feed themselves

Toddlers still can't do many things for themselves and need lots of help from their grown-ups.

Stand up and pretend to be a toddler ,Do some wobbly walking around the room .Try not to fall over.

3. Child.

This is the stage you are at now.You are learning to be independent, which means there are more things you can do on your own.

What can you do on your own now that you used to need help with ?

An important part of this stage is starting school .This stage is full of lots of changes and children learn to do lots of things, such as :

reading,

writing,

counting,

riding a bike,

swimming.

4.Teenager

The teenage stage is from ages 13 - 19 .Teenagers are getting ready to be adults and are becoming independent .

Teenager's bodies change a lot during this stage .They get taller and start to look more like adults. These changes are because of things called hormones. Hormones 荷尔蒙 are things inside your body that make your body change.

Because they're growing so quickly. Some teenagers eat a lot. Many teenagers like to sleep for a very long time. Some teenagers can be a bit grumpy at times.

Do you know any teenagers? What are they like?

5. Adult.

Being an adult is also called being a grown-up. There are lots of things that grown-ups can do. A lot of adults get jobs and live on their own ,with friends or with a partner. At some point, many adults have children of their own, which starts the human life cycle again.

what job would you like to do when you're an adult?

6. Old age.

Old age is the later stage of being an adult.

Older people retire, which means they stop working. This means they have plenty of time to enjoy themselves. They may find a new hobby or spend extra time with their grandchildren.

Some old people have gray or white hair. Sometimes old people might move more slowly because their joints and muscles ache. Older people's eyes might not work as well so they might need glasses for reading or seeing far away.

When you are older. What hobbies would you like to try?

Brush Teeth

看视频，这么多年的牙好像白刷了

fluoride /ˈflʊəˌraɪd/ 氟化物

Brushing your teeth every day isn’t just a way to keep your mouth feeling clean. It’s a way to keep your whole body healthy, too.

We should brush twice per day, for 2 minutes each time.

When you brush correctly, you eliminate the plaque /plæk/ 牙磨斑 buildup and bacteria that can otherwise collect between your teeth and on your tongue. This can prevent gum disease and tooth decay, as well as promote a stronger immune system and a healthier lifestyle.

What you need to brush your teeth

The first step to brushing correctly is making sure you’re prepared with the right tools. You’ll need:

1. a toothbrush
2. fluoride /ˈflʊəˌraɪd/ 氟化物 toothpaste
3. floss
4. mouthwash (optional)

How to brush your teeth properly, step by step

The entire process should take about 2 minutes. Practice timing yourself until you get used to how long 2 minutes feels when you’re brushing.

When brushing your teeth try to concentrate on one tooth at a time,You should spend a few seconds on each tooth before you move on to the next one

1. Lubricate your brush with a small amount of water, put a small amount of toothpaste - about the size of a pea - on the head of the toothbrush.
2. Insert the toothbrush into your mouth at about a 45-degree angle to your gums and use gentle ,shot circular strokes to brush your front teeth.
3. Brush the outside surfaces of your teeth, making sure to get the back molars and upper areas of your chewing surfaces.
4. Flip the toothbrush upside down to get the inside surface of your top front teeth. Flip it back around to get the inside surface of your bottom front teeth.
5. Brush your tongue to get rid of any bacteria buildup and plaque that has gotten stuck there during the brushing process.
6. Spit out the remnants of toothpaste, saliva and water into a clean sink .Finish by rinsing your mouth with cold water.

How to brush your teeth with an electric toothbrush

Brushing your teeth with an electronic toothbrush head is slightly different since the brush head rotates or vibrates on its own.

1. Prepare your toothbrush by rinsing it with a little bit of water. Add a pea-sized amount of toothpaste on top.
2. Turn on your electric toothbrush and start at the back bottom row of your teeth,holding the head at a 45-degree angle toward the gum line.
3. Applying light pressure, move methodically, one tooth at a time, buffing each tooth with the rotating vibrating brush head.
4. Switch to the back top row of your teeth and repeat, cleaning and polishing one tooth at a time.
5. Use the electronic brush head to stimulate and clean your tongue, moving it slowly across your tongue’s surface.
6. Spit out the remnants of toothpaste, saliva, and water into a clean sink. Finish by rinsing your mouth with cold water.

Tips for Brushing

1. 更换频率Your toothbrush should be replaced every 3 to 4 months or when you notice the bristles starting to bend and look worn out. Always replace your toothbrush after you recover from a cold or the flu.

If your toothbrush has been overused, the bristles /ˈbrɪsəl/ can become frayed 磨损and brushing loses some of its efficacy./ˈɛfɪkəsɪ/ 功效The bristles of a brush are the thick hairs or hairlike pieces of plastic which are attached to it. (刷子的) 毛 If you talk about the efficacy of something, you are talking about its effectiveness and its ability to do what it is supposed to. 功效

2.含氟牙膏A fluoride toothpaste is the best choice for most adults.

Fluoride fortifies巩固 your teeth against decay. Some very young children shouldn’t use fluoride toothpaste. However, the ADA still.recommends that:

1. children younger than age 3 whose first teeth have come in can use a smear of fluoride toothpaste about the size of a rice grain
2. children 3 to 6 can start using a pea-sized amount of fluoride toothpaste
3. Special fluoride-free toothpastes also exist for younger kids if you’re worried about them swallowing the toothpaste.

3. 频率Always brush twice a day, preferably first thing in the morning and again right before you go to sleep. Try not to eat or drink anything once you have brushed in the evening.

4. 帮孩子刷牙When brushing someone else's teeth, try to stand behind them so you are looking down on their mouth. This will allow easier access to the mouth and a better view of their teeth. If they are taller than you, have them sit in a chair.

5. When brushing the inside surfaces of the upper and lower teeth , try to avoid standing too close to your mirror, as the flick will usually cause some spray.

Floss

Best floss picks and how to use them

It’s important to floss regularly and correctly to maintain good oral hygiene and avoid gum disease. Floss picks can be used as an alternative to either string floss or water flossers in your oral cleansing regime.

Here’s everything you need to know about floss picks; their benefits, the best floss pick, floss picks vs string floss, and more!

What are floss picks?

Floss picks, also known as floss sticks, are small pieces of plastic with a line of string floss threaded through. They’re an alternative to string floss or water flossers. They come in all shapes and sizes. Most come to a sharp point at one end which helps to pick pieces of food out from between your teeth. Things to bear in mind when choosing a floss pick include the shape and size of the handle – the longer it is, the easier it is to reach in and effectively clean around each tooth.

Flat versus curved:

Curved floss picks are generally more effective at cleaning out your teeth than flat ones since they curve around to reach each tooth better.

Don’t forget:

Floss picks shouldn’t be confused with waterpiks. Whilst waterpiks are a quick and effective way of flossing, floss picks can be thought of as string floss that’s easier to handle.

Benefits of floss picks – should you use them?

They’re easy to use. Traditional string floss can be fiddly And reaching into your mouth to effectively floss the back teeth can be quite difficult. Thanks to its handle, this is substantially easier when using a floss pick.

They’re 2-in-1. Yes, flossing is the main use for a floss pick. But the clue’s in the name: pick. As well as string floss, you have the addition of a plastic pick, which you don’t get with any other kind of flosser.

They’re less messy than string floss. Honestly, string floss can be gross. It’s no fun to be flossing with smelly plaque on your fingers. With a floss pick, the handle provides a clean solution.

There are benefits to using floss picks, but ultimately, it’s a matter of preference. If floss picks work best for you, then stick to them!

How to use floss picks

1. Holding the stick, slide the floss between your teeth.
2. Move gently up and down. It’s important that you’re not too rough – vigorous flossing can cause sore gums.
3. Let the floss wrap around your teeth. Make sure it curves below the gum line, too!
4. Use the pick end to gently slide between each tooth.

The principles of flossing effectively still apply when using a floss pick instead of string floss, so make sure you know how to floss correctly before starting!

Can you reuse floss picks?

The short answer is no. While it may be tempting to use a floss pick more than once, it’s a very bad idea. This is because bacteria and plaque which may be initially dislodged by the floss pick can be reintroduced in other areas in the mouth. This can lead to more plaque.

While floss picks themselves aren’t reusable, there are similar devices which are. These are called “floss holders”. However, they’re a bit tricky and involve threading your own floss into a piece of plastic. Furthermore, these aren’t designed to be as effective as floss picks, so they’re generally more hassle for less results.

Top tip: if you’re concerned about the effect that your floss waste is having on the environment, consider trying out a water flosser. Unlike floss picks and string floss, they’re reusable!

Floss picks vs string floss

Easier to get to the difficult parts in your mouth It’s flexible

Easier to hold Can be easily adjusted to effectively floss each tooth

You don’t have to touch any of the plaque Doesn’t use the same piece of floss continuously – avoids spreading bacteria

Often easier for kids Less waste

There isn’t a huge amount of difference between using floss picks and string floss. Generally speaking, picks are easier to use, purely because they have a handle. Despite this, string floss on its own is more flexible and therefore often more effective when flossing teeth.

Floss picks for kids

Flossing isn’t just hard for adults, it’s difficult for kids too.

Floss picks are substantially easier for children to use: rather than fiddly string, they get a firm handle to hold. This makes it easier to reach teeth at the back of the mouth.

Summary

Floss picks are a useful way of flossing effectively. If you find string floss fiddly or have kids who hate flossing, it’s worth trying them out. However, they do have a negative impact on the environment since they are single-use plastic devices. So, if you’re concerned about your environmental impact, they may not be your favorite option.

It’s more important for your oral health to make sure that you’re flossing regularly and correctly than it is to use a specific kind of flosser. Your choice of the flosser you use is up to you: if floss picks work for you, go ahead and use them!
