Collecting coins in my hobby, and it has brought me a lot of fun. Now I share the hobby 1 my children. Getting children interested in coin collecting 2 easy. Here are four ways I have used to get my kids 3.
Start small
Many coin collectors buy coins of great value（价值）. But children needn't consider the value. Let your children start with a set 4 Jefferson Nikcels（5分镍币）. This set is the 5 to collect and almost all of them can be 6 in coin shops.
Bring home surprise
OK, you know the coin they are looking at is 7 and common. But you should be excited at 8 they are looking at.
Buy them a nice box
Go shopping and choose 9 nice box for your children 10 their coins in. 11 will help them to keep their collection organized. 12, having a nice box will keep their excitement high. Every time they show their collection to their friends, they will feel good.
Give them one of 13
Find a great coin in your collection and hand it down to your children. This coin needs to be a bit common, so 14 something happens to it, the world doesn't end. But it also 15 to be special, or your children may have no interest in it.
Do you often feel tired? Do you sometimes feel uncomfortable on your neck and back? It may because of the radiation (辐射) from your computer. If you spend three hours or more in front of a computer, you may feel terrible because of the radiation.
The safe amount of radiation is 25V/m. Do you know how much radiation our computers give off?
Keyboard: 1,000 V/m Mouse: 450 V/m
Monitor: 218V/m CPU: 170 V/m
Laptops: 2,500 V/m
Ways to protect yourself from harmful computer radiation:
1 Put some green plants on your desk. They can take in radiation.
2 Drink two to three cups of green tea a day and eat an orange daily. They keep us healthy.
3 Use a screen filter (屏幕过滤器) for your monitor.
4 Avoid having metal (金属的) objects near your desk.
5 Put the back of the computer to the wall. Most of the radiation comes from the back.
6 Keep your monitor at least 50 cm away from your face.
7 Allow fresh air to move around your computer room.
8 Eat healthily — especially fruit and vegetables.
9 Turn off your computer if you have to rest nearby.
