    A city without cars would be very strange, right? But Venice is such a city.

    Venice is in the northeast of Italy. It wasn't built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater is everywhere around the city.

    Even so, traveling isn't that difficult. The waterway has always been the best way to get around. There are 117 waterways and more than 400 bridges that connect one river with another and can also guide you where you want to go. People in Venice move from place to place by boat. They like to enjoy the scenery and cool summer nights while taking boat trips. They can talk to other people as they go along the river.

    Water makes the city special, but it is also a big problem. Sometimes tourists will have such strange experiences. One moment they walk across the Rialto Bridge, and there's nothing special. But when they come back to the bridge an hour later, it's underwater and everyone is wearing rain shoes.

    Once, people used too much underground water. This made the city get lower little by little. Now the city has gone down by 23 centimeters. Another problem is that the temperature has risen over the years. This has made ice of the Arctic Ocean（北冰洋）melt（融化）.

    Scientists are trying different ways to stop the city from getting even lower. The Italian government has asked some of Italy's biggest companies to build the MOST project, which was planned to be built under the seawater to stop the rising water. Anyway, this project is helping solve the problem.

    Everyone loves chocolate- kids and grown-ups alike, and no matter what your age is, you are sure to enjoy learning more about chocolate. Read on to learn some fun facts.

    All the chocolate we eat comes from a special plant- the cacao tree. These trees produce a special kind of seeds. {#blank#}1{#/blank#} Then they are used to make chocolate.

    {#blank#}2{#/blank#} So they grow best when under the branches(树枝) of taller trees in the forest. They won't begin to bear fruit, however, until they are at least three to five years old. Cacao trees produce beautiful flowers all the year round. {#blank#}3{#/blank#} A kind of small flies pollinate(对......授粉) these small flowers. These flies are so small that they easily stand on the head of a needle(针状物). They beat their wings very fast—1, 000 beats a second! {#blank#}4{#/blank#} A cacao pod(可可果) has about 30—50 seeds. This is enough to make about seven milk chocolate candy bars!

Many parents like twins(双胞胎) a lot. For many years, people think that twins have a secret language. A lot of parents of twins say that their children have a secret way of talking to each other by using some words they don't understand. "The twin language" was very special in people's minds for a long time. However, a study shows that twins hardly have secret languages. So why do people think that?

When babies are learning to speak, they often make sounds and their parents don't understand them. For example, a child may call a bottle "baba". Since twins are learning the language at the same time, they often make the same mistakes. So, if one of the twins calls a bottle"baba", the other possibly starts to do the same. Soon, the twins are using the same inaccurate word. Parents may think of this as a secret language. In fact, the twins are learning new words like any other child.

A study shows that true secret languages don't happen very often. It happens because babies spend a lot of time alone and don't have many people talking around them.

Some studies show that it often takes longer for twins to begin speaking than for non-twin children. This could be because parents of twins can be busier than parents with just one baby, so they don't have much time to spend with their twin babies. Because twins understand each other's language mistakes, it may take them longer to learn words right.

As twins get older, like many non-twin children, they may make secret words for things they don't want their parents to understand!

Now, camping is getting popular among young people. It's a great way to be outside and enjoy nature. If you like to be in trees, mountains or by the lake, you are sure to have a good time when you go camping. Here is some advice for camping.

You need to put up your tent only in a safe (安全的) place. If you put up your tent in other places, you may meet dangers. Remember to do it for your safety.

Fire may be not safe, so use fire only when you must. Make sure to put the fire out（熄灭) when you don't use it. Don't go away or sleep when the fire is on.

Don't forget to take your phone, and you can take photos of the beautiful trees and flowers. You can see the beautiful natural sights (风景). Later, you will feel relaxed.

Sometimes, we may go to the deep (深的) forest. And it's easy for us to get lost. People often get lost in the forest. It's a good way to take a map with you. Now, we have GPS in our phones. Maps and GPS can help you when you get lost.

The Golden Snub-nosed Monkey(金丝猴) is a special kind of monkey that mainly lives high up in the mountains in China, Vietnam and Burma. They have a flat nose that points up, which is really two nostrils(鼻孔). This helps them breathe well in the thin air up high in the mountains. Their fur is golden and very thick, which not only keeps them warm in the cold mountain weather but also helps them go well with their forest homes.

These monkeys like to live together in groups with a big, strong male monkey as their leader. The leader protects the group and guides them to food. They communicate with each other through sounds and body movements.

Golden Snub-nosed Monkeys spend most of their time in the trees. They love to climb trees and jump from branch to branch. They are very good at moving around in the trees. They eat mostly plants like leaves and fruits, but they also eat insects and small animals when available. Sadly, these animals are not common to see because of human activities. Many trees are cut down every year. We need to help protect these monkeys and their homes.

These monkeys are very beautiful and important for the mountains. They are a symbol of nature's beauty and a reminder of our duty to protect the environment. By learning about them and helping to keep their homes safe, we can make sure that people in the future can also see these wonderful animals that live in the mountains.
