Recently, many people have begun to try a new way of doing shopping through the Internet. They are very interested in it. Why is itbecoming more and more popular now? There are some reasons. First, more and more people have their own computers and their computers can be joined with the Internet. So it is possible for many of them to do shopping through the Internet. Second, shopping through the Internet can save them some money and a lot of time. Third, they don't need to go to the shop themselves.  Because of these good facts, few people refuse it.
   On the other hand, some people don't like this new way of shopping. They are worried about the safety of shopping online. Customers(顾客)can only see the pictures of a product on the Internet. And they can't enjoy the pleasure of buying things in a large supermarket or a wonderful shopping center. These are the reasons why they do not like it.
   But I think more and more people will like this new kind of shopping in the future.

    When you are in England, you must be very careful in the streets because the traffic drives on the left（左边）.

    In China, before you cross a street, you must look to the left first and then the right. If the traffic lights are green, the traffic can go. People on foot mustn't cross.

In the morning and in the evening when people go to or come from work, the streets are very busy. Traffic is the most dangerous then.

    When you go by bus in England, you have to be careful, too. Always remember the traffic moves on the left. So you must be careful. Have a look first or you will go the wrong way.

    In many English cities, there are big buses with two floors. You can sit on the second floor. From there you can see the city very well. It's very interesting!

Your teacher asks you to collect your classmates' opinions about their favorite school lunches. After asking everyone, you have collected a lot of data(数据) or information and aren't sure how to organize it. Creating a graph (图表) can be a great way to organize and share your data.

Graphs show data in a direct way that is easy to read and understand. There are many different kinds of graphs. Different graphs are better for different kinds of data. Read on to find out about the types of graphs in math, as well as the key parts of a graph.

Bar chart

A bar chart has a horizontal axis (横轴) and a vertical axis(竖轴). It has a title that explains what it shows, and different bars are used to show different amounts. There's a number line along the vertical axis and labels(标签) along the horizontal axis, labeling the data.

Pie chart

A pie chart helps organize and show data as a percentage of a whole. True to the name, it looks a bit like a pie and uses a circle to show the whole. Pieces of that circle, or "pie", stand for the different things. The different pieces of the pie are different sizes depending on how much of the whole pie they show. Each piece is labeled to show what it means.

Line graph

Line graphs are used to show changes to numbers over time. They show what we call continuous data. The vertical axis explains the data being shown. We mark data on a line graph. The different data points are then joined up with straight lines, so we can look at the trend(趋势) it shows.

Flow chart

A flow chart shows the different steps in something using boxes and arrows(箭头). It can often have many different directions and different paths you can take using the information it asks for. Flow charts can be great for explaining a huge process by breaking it down into different steps.

Hi, my name is Li Hua. I come from Huizhou, China. I am twelve and I am a student of Grade Seven. I like red very much. There are four people in my family. And these are my four good friends.

Printing was invented in China. At that time, people could only make one book at a time by hand for a few {#blank#}1{#/blank#}(月). But today, it takes several minutes to print a {#blank#}2{#/blank#}(单个的)book. In fact, people can get information much more easily with an Internet connection than in printed {#blank#}3{#/blank#}(类型). In a way, we can {#blank#}4{#/blank#}(把……比作) the invention of the computer to the {#blank#}5{#/blank#}(推行) of a non- paper age. If things are going on in this {#blank#}6{#/blank#}(方向), computers may really {#blank#}7{#/blank#}(取代) books one day. Let's wait and see. 

 Of course, if you are a new user, you have to use the computer {#blank#}8{#/blank#} (合适地). When you want to {#blank#}9{#/blank#} (借来) one from others, you'd better read the {#blank#}10{#/blank#}(说明书) first. If you want to know more, you can also read some books about it. 

 Governments around the world are pushing for an end to plastic bags. More and more businesses are changing to paper products. Using paper is thought to be better than plastic.

However, it is harmful to the environment, too.

 Firstly, paper bags are made from trees. Trees, as you know, are good for the environment. They can slow down climate change. An increase in the use of paper bags can cause more deforestation(毁林).

 Secondly, the production of paper things requires more energy and water. About 10 percent more energy and four times as much water is used to produce a paper bag than a plastic one. You might say that we can use recycled paper to save that energy and water. This seems to be a good idea. However, it takes even more energy and water to go through the recycling process than to make a new paper bag. Products made from recycled paper are also often short-lived.

 Furthermore, paper products are heavier than plastic ones. That means they require more fuel to transport. Seven trucks are needed to transport two million paper bags, while only one truck is needed to transport the same number of plastic bags. The increased weight also leads to a larger amount of waste once the bags are thrown away.

 So, paper products are actually a lose-lose for both the environment and businesses. They are more expensive than plastic products. A paper straw costs about 5 to 12 cents, while a plastic one usually costs only about 2 cents.

 In my opinion, the most environment-friendly way is to avoid single-use things altogether. Products like glass water bottles and steel straws can be used over and over again. They are much better than either paper products or plastic products. By increasing the use of these items, you can greatly reduce your throwaway waste and truly make our earth a greener place!
