The giraffe is the tallest modern land animal. It can be over 5. 5 meters tall. Its neck alone may be 1. 9 meters long. Yet the giraffe has only seven bones in its neck, the same number as in the humans'. Even a small bird has many more bones in its neck than a tall giraffe. Each bone in a giraffe's neck is very long, while the bones in a human's neck are short. That makes the difference. A female giraffe gives birth to one baby at a time. The baby, called a calf, is about 1. 9 meters tall at birth. By the age of eight it is full-grown. The giraffe eats mostly leaves. Because it has a long neck, it can reach the high leaves on the trees.

    Songs help memories

    The power of music

    Most people can remember important news stories clearly, whether it was the murder of President Kennedy in the US or 9/11.But now psychologists Martin Conway and Catriona Morrison, from the University of Leeds in the UK, are investigating how music can create “autobiographical memories” of the main events in our lives. The study is online. People have to choose a song by the Beatles and describe the memories that they have when they listen to it.

Reminiscence bump

    Morrison explained that they looked at different age groups and their memories. We often remember more from when we are teenagers and this is called “the reminiscence bump”. This is the time in your life when you form your idea of who you are. For older people who have memories related to the Beatles' music, most of those memories are from when they were teenagers. But younger people also had clear personal memories from their past.

    She loves you

    This study was different from other memory studies, because people remembered events from their past with lots more details. Morrison explained:     “It was like people had travelled back to the past, and they had very clear memories of things that had happened. When they heard a song like She Loves You by the Beatles, they could remember one night in autumn 1963.They remembered what they were wearing, what the weather was like and what their friend said to them. You get a lot more information than if you just say, ‘tell me about a night you remember'. ”

    The study has found that music could be used with people who have problems remembering the past. “You could use music to help improve people's ability to remember,” said Morrison. “In the future, we would like to do more experiments to see how useful music is in helping people to remember the past, and compare it to other things that might also help.”

    Techeng Island(特呈岛)lies in the southeast of Zhanjiang. The villagers there used to make a living by fishing. But now, most of them make much money by doing business. They believe that their island is a gift from nature and they give thanks to it every day. In 2003, President Hu Jintao came to visit the island and pointed out that the government of Zhanjiang should take the is land into a "civilized new ecotourism island"(文明生态旅游新海岛). Since then, the island has opened a new page in history.

    Today, the island has become a popular place for tourists. It takes you about 15 minutes to get there by boat from Maxie Pier(码头)near Haibin Park. But it is a just 8­minute boat ride from Zhanjiang Port Pier. In the resort(度假村), you can not only enjoy the fantastic sights but also have a lot of interesting things to do, like walking on the beach, visiting the museum and enjoying the delicious seafood. The best way to relax yourself is to enjoy the hot springs(温泉)there.

    Welcome to Techeng Island! It's a place to visit!

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.
