Today some people call Amsterdam the "City of Bicycles" because it is a city which is flat and convenient（方便）for bicycles.

    In the 1960s, a group of cycling fans1an idea . They believed that it would be better for everybody if only bicycles were allowed in the city centre. They were2that this would help to save energy, reduce pollution and provide free public transport. The group painted hundreds of bicycles3and placed them in public places around Amsterdam for people to use.4was allowed to take them and use them for short journeys, whether he was a local or a foreigner, Wherever someone finished a journey, they would5the bike there for someone else to use. The problem was that it didn't work-thieves took all the bicycles6 weeks!

    7,more than thirty years later, the "white bike" is back in town-this time with a computer chip(芯片)to8 its every move! To take a bicycle, you have to put a special card inside. The new "White bike" is not white any more but is an unusual9with bright colours. The bikes are parked at special parking places and people who want to use them have to take them to another place that has enough room.

    There is already less traffic in central Amsterdam, 10 both locals and tourists have been using the white bikes. Thanks to the good ideas of lots of people, like the cycling fans in the 1960s, many people around the world have been enjoying city centre streets without cars for many years.

A Chemical reactions(化学反应)make for some great experiments.You can make use of the CO₂ (carbon dioxide) given of by a baking soda and lemon Juice reaction to blow up your balloon! 

What you'll need:

★Balloon 

★About 40 ml of water (a cup is about 250 ml so you don't need much) 

★Soft drink bottle ★Juice from a lemon 

★1 teaspoon of baking soda Instructions: 

★Before you begin, make sure that you pull the balloon long to make it as easy as possible to blow up. 

★Put the 40 ml of water into the soft drink bottle. 

★Add the baking soda and mix it with water. 

★Put the lemon juice in and quickly put the balloon over the mouth of the bottle. 

What's happening?

If all goes well, then your balloon should inflate(膨胀)! Adding the lemon juice to the baking soda creates a chemical reaction and produces CO₂. The gas rises up and escapes through the soft drink bottle. It doesn't, however, escape the balloon, pushing it outwards and blowing it up. 

The number of people living in the rainforest is rising，but the rainforest itself is becoming smaller!

During the 20th century，huge areas of rainforests were cut down. More and more people in Brazil and Indonesia moved into rainforest areas to find land for living. Local farmers cut down trees to grow crops（庄稼）. Large companies have also moved into the rainforests to develop their factories. 

The problem is that the area of the rainforest is becoming smaller and smaller. Scientists say that destroying （破坏） the rainforest is ▲ the earth and should be stopped. But why？Rainforest plants help to clean the air. What's more，different parts of rainforest plants can be used to produce useful medicines and may be the key to solving serious health problems. 

So how can we solve the problem？Governments can make some rules to protect their forests. Companies can create jobs elsewhere，so that fewer people have to live and work in the rainforests. Farmers are encouraged to plant crops in certain areas，and this helps to stop the soil from being washed away and produces better crops. 

More than half of the plants and animals that live in the rainforest can't be found anywhere else in the world. It is important to make sure that these forests are used well and protected by people. 

Domestic drama film Better Days (《少年的你》) led the Chinese mainland box office nowadays. It tells the story of two high school students whose fates were changed by an accident. Seventeen-year-old Nian meets Bei, a tough street kid. Nian is the subject of cruel bullying (欺凌) at high school. The film is heartwarming and heartbreaking at the same time. The movie is set before College Entrance Examination. It offers thoughts of competition between teenagers and national issues of school bullying. 

Bullying is a sad reality that has affected many kids. What is worse about it is that bullying can lead to more result s such as lowered self-respect, poor performance and self-harm among kids. Here are a few anti-bullying dos and don'ts for you. 

·Walk away from a bully and tell an adult. It's OK to be scared and ask for help. 

·Don't look down when a bully says something. Stand tall and look into the bully's eyes. 

·Take a moment to calm down before responding to a bully. It is tough to think straight, and recall the reply you've practised with your parents, if you're scared. 

·Speak clearly without making the bully angry, say, "I want you to stop laughing at me"

·Use your best poker face (扑克脸). The less scared or affected you look, the less the bully will do. 

·Get between a bully and his/ her target. Go and stand beside a child who is being bullied. Turn him/ her away from the bully, and walk with him/ her towards an adult. 

·Avoid being alone with a bully. Bullying usually happens where adults are not present, so you should avoid empty hall ways, bathrooms or areas of the playground with bad sight lines to an adult. Try to sit near the front of the bus, and be near the cafeteria manager at lunch time.
