Every year, millions of birds are killed or hurt when they fly into buildings. Why does this happen?  Birds are flying into windows and tall buildings that are all covered by glass.

Many birds fly from one place to another. Most of the time, they live in the wild, such as forests and wetlands.  They might see small trees and flowers inside a window and want to rest on these plants. The birds do not know there is glass between them and the plants.  

Some birds fly at night. They use the moon and stars to help guide them in the right direction. Tall buildings with lights on at night can confuse（迷惑）the birds.  The birds see the light, but they cannot tell that the light is coming from inside a building. They fly toward the light and crash into a building. On many mornings, there might be several dead birds lying on the ground.

  Many office buildings now turn off their lights at night. This helps reduce the number of birds that fly into buildings and it also helps save energy.

Taking stress out of exams

Pre-exam stress is one of the biggest problems in students' lives. It makes you feel bad and stops you from thinking clearly. So here are some tips to help you lower the stress of exams.

The best way to deal with exam stress is to have a good study plan. Decide which subjects to study every day and how much time to spend on each one. And don't wait until the last minute to study everything.

When we don't understand something, we feel stressed. It's normal. But don't worry about it, do something about it! Ask your teacher for help. You may find it hard to believe but all teachers want their students to do well in exams.

Your body needs exercise for your brain to work better. So don't study all the time. It can just make you more stressed. Do some sport, go to the gym or just go for a walk but get up and move!

It's important for your brain to rest so try to get eight hours' sleep every night. Eat a healthy diet and avoid drinks with caffeine that can stop you from sleeping well.

Finally, if you have followed all this advice and you still feel stressed, then don't keep it a secret. Talk to someone, your mum or your dad, a friend or a teacher and tell them how you feel. We all need help sometimes.
