An American group developed the rooftop(外屋顶)gardening in the early
1980s . The group is known as ECHO . This idea was to help people living in cities
who didn’t have to grow vegetables . And now it is becoming more and more popular
in many other countries .
To build a rooftop garden,four things are necessary . You need a roof strong
enough and four pieces of wood to build a box . Grass cuttings in which to plant your
garden and a thin piece of plastic on which to pit the cut grass are also necessary.
Begin by testing(检测)your roof to make sure it is strong enough . Cut and
collect some grass . Cover the roof with a thin piece of plastic . Then you build a box
from the four pieces of wood . The box has no top or bottom . It should be about 8 cm
deep . It can be as long and wide as needed. Put the box on the plastic . Then fill it
with the cut grass . Water the grass and push it down by walking on it . After about
three weeks ,the rooftop box is ready for planting.
Put the seeds(种子)directly into the wet grass. It is important than the grass is kept wet until the plants begin to grow .When the plants are growing, you will need to water them every day unless it rains. And birds must be prevented from eating the seeds or new plants. They will also need some liquid fertilizer(液体化肥).You can make your own liquid fertilizer if you can get wastes from chickens. Put the chicken wastes in cloth bag .Then put the bag in a big container of water .After about one week, the water becomes a good liquid fertilizer.
The rooftop garden is a good place to grow peas, tomatoes and onions .If the box is deep enough, potatoes and carrots will also grow.

We set up some recycling bins around the club and wanted to encourage everyone to recycle. Also we decided to design some T-shirt too; quite a few of us have been watching “Spring watch” on TV so we were very excited when Chris Packham came to visit us!
When Chris came to the club we did different activities. After lunch we did a trash pick and then weighed the bags of rubbish to see who had collected the most. It makes the club tidier and a safer place for wildlife.
We then went off to find things around the club and make a list of things than have an effect on the environment. Some of the things we lisped were oil, which can pollute the beach and water ,and wasting drinking water from taps and pipes .We are now going to keep on recycling and doing trash picks as well as encouraging people to put their rubbish in the recycling bins . There are also some other ideas of using rain water to wash to wash off our boats instead of drinking water; this will be our next project.

Xiaofan went to a shop and bought a tape. Back home, he started to record what he wanted. After that, he took out a tool box and connected his tape player with the new tape to his alarm clock. A special alarm clock was born. At a certain time in the morning, the tape player would play soft music with a low and sweet voice of a young girl, “Wake up, please.” Five minutes later, the tape player would play again, and it might be loud music. At the same time, he could hear a recording of his parent, “Wake up at once, or you’ll be late!”
Several days later, Xiaofan got used to the sound of the recordings. After the recordings, he was still sleepy, and even fall asleep again. That was terrible! So he went to the library and borrowed plenty of b ooks home to deal with his problem of getting up late.

For Schultz, a 77-year-old man, this is a chance of a lifetime. Schultz is part of a group of around 50 Germans who are on a bus journey along the ancient Silk Road.
Speaking of his journey, he says: “I have been dee* interested in the Silk Road since I was a child, but now I finally have a chance to experience it.”
The two-month bus journey will take the group through Germany, Russia, and other 4 European countries. They will then enter China from the country’s western part. It will be an unforgettable memory for them.
Nearly half of the 13,000-kilometer trip will be inside China. From Xinjiang in the west to Shanghai in the east, the German visitors will see more than 20 Chinese cities. “We have managed the trip of the Silk Road for around 10 years. An increasing number of people, not only from German-speaking countries, have been joining us," says Liu Guoqiang from China Tours.
Almost 26 million foreigners traveled to China in 2015, and about 5 million of them were from Europe. Beijing, Xi’an, Shanghai and the Changjiang River are traditional Chinese travel destinations for European tourists. Speaking of where he wants to go, Schultz says, “Compared with modern cities, the culture in western China attracts(吸引)me more.
As Shi Xiang, head of the China Tours, says, “Being a new brand to attract foreign visitors, the Silk Road is good for people to know more about China, especially the northwestern part of the country.”

Every year, in late March or early April, a boat race takes place o n the Thames River, England. This boat race is an event between the two most famous and also the oldest universities in Britain – the Oxford(牛津大学)and the Cambridge(剑桥大学).
The idea for the boat race between the universities came from two friends – Charles Merivale, a student at Cambridge, and his friend Charles Wordsworth who was at Oxford. They decided to set up a boat race between the two universities. On March 12, 1829, Cambridge sent a challenge to Oxford first.
When the first boat race took place in a small town by Thames, eight students from each university became th e compe*s. Crowds of twenty thousand traveled to watch. It was so exciting. And the Oxford was clear winners. Later on, not only did the students from the two universities take part, but also some social groups attended the event. By 1845, with the small town becoming too crowded, the boat race had moved six miles up to the village – Putney. From 1856 on, the race has been held every year except war years. This boat race is considered to be “the world’s oldest sporting challenge”.
The race is four and a quarter miles in just 20 minutes and the compe*s often face difficulties. It usually takes six months for the two teams to prepare for the big days. In the past, the Oxford was mostly the winners. But things have changed from 1993 on. The Cambridge has won more.

There was a little boy whose name was Peter. He lived in a village close to the sea. The villagers built sea walls to keep sea water from the doors of the houses. But once the sea walls almost put the village in great danger.
One day, Peter was walking on his way back home along the sea wall when it began to rain. All of a sudden, he saw a hole in the wall, from which the sea water was running. Peter shouted for help because he knew the hole meant that the sea was making its way through the sea wall, but no answer came. He realized he should do something else as quickly as possible, or the sea water could be pouring over the whole village. He started to rush towards his village.
