Spiders are not insects as many people believe. They belong to a class of animals called arachnids(蛛形纲动物). Spiders have eight eyes, four pairs of legs, and can grow a new leg if they lose one. A spider’s body is divided into two sections: the abdomen(腹部) and the thorax(胸部).The legs, eyes, and mouthparts are in the thorax section.
Most spiders have poison glands(毒腺)and sharp teeth. They use their sharp teeth to force poison into the insects they catch for food. This poison can make an insect lose the ability to move, and the helpless insect is then devoured by the spider.
Spiders usually have silk glands under their abdomen. They produce a liquid(液体)that is thicker than water from their glands. When the liquid comes into the air, it dries into silk. Many spiders use this silk to form webs to catch insects and to make cocoons(茧)that protect their eggs. This amazing silk is also used to create lines that spiders hang onto as they travel to new areas.
Spiders live in almost everywhere on earth. The only places where there are no spiders are the coldest places, the highest mountains and the seas.

On a hot day, it can be hard to know what to do to feel good.
Playing in water is one way to feel cooler. Taking a cool bath or a shower can feel really good on a hot day.
It is also important for us to drink water. If you feel thirsty, you should drink water immediately. On hot days, you can lose about 16 glasses of water in one day, so many doctors advise that you should try to drink at least that much every day. Mixing a little fruit juice into your water is a fun way to help you drink plenty of water.
The food we eat also makes a difference in how we feel in the heat. Cold food, such as ice cream and drinks with some ice, can cool down our bodies. However, eating spicy(辛辣的) food makes our bodies even warmer.
The clothes we wear can help us feel cooler as well. Light-coloured, light-weight clothes feel cooler in the sun than dark, heavy clothing. Loose(宽松的）clothes are more comfortable in the heat than tight(紧身的）ones.
Even though it is not healthy to run around during the hottest time of the day, that doesn’t mean a hot day is not fun! You can read stories in your room. You can also paint or draw without moving your body too much. These are just some of many cool things to do on a hot day.
