What is China’s High-Speed Rail (HSR)? Generally speaking, a rail network that offers 200–350 kph trains is an HSR network. Now, China has the largest high-speed rail network in the world. There are “4 vertical lines and 4 horizontal(水平的) lines” for the main China HSR network. This means there are four north–south high-speed rail lines and four east–west high-speed rail lines. They are the basis for the China high-speed rail network.
The four north–south HSR lines
Beijing–Shanghai Route
* Length: 1,318 km
* Design speed: 350 kph
It connects two popular cities and reduces the journey time from 12 hours to 5 hours (2 hours by air).
Beijing–Guangzhou–Shenzhen–Hong Kong Route
* Length: 2,240 km
* Design speed: 350 kph
It is the longest passenger-transport dedicated high-speed rail line in the world. It connects North China, Central China, and South China.
Beijing–Harbin Route
* Length: 1,300 km
* Design speed: 350 kph
It connects Northeast China with the national capital, Beijing. It cuts the journey time from 12 hours to 6 hours between Beijing and Harbin.
Hangzhou–Shenzhen Route
* Length: 1,600 km
* Design speed: 250–350 kph
It connects the Yangtze River Delta and the Pearl River Delta. The Hangzhou–Ningbo section is passenger-transport dedicated. The rest trip is mixed for passenger and cargo (货物) transport.

Environmental pollution does great harm to us. Tens of thousands of people die of disease caused by pollution. The area of desert in the world is growing and the weather is getting worst because the forest damage. The waste gas and liquid from factories have polluted air or rivers. Everyone is eager to get fresh air, pleasant weather and safe drunk water.
Luckily more and more people have realized what serious the problem is and they were trying their best to take measures to protect the environment. Therefore, we still need to encourage more and more people to join us in protecting their environment. Let’s keep in the mind that protecting the environment is saving ourselves!

During summer days, warmer temperatures bring pests like mosquitoes. Mosquitoes can cause lots of trouble for people.1.. They even can spread many serious diseases.
An easy way to protect yourself against mosquitoes is using repellents (驱虫剂). Joseph Conlon, an advisor of the American Mosquito Control Association, recommends using repellents that are registered with the Environmental Protection Agency, which ensures that they actually do no harm to humans. 2.. But some repellents can provide 4-6 hours of protection if the quality of them is excellent.
Mosquitoes are also very weak. A slight wind from a fan can help keep them away from you. It turns out that many mosquitoes are not very good fliers. 3..
Another way is to clear all the standing water (积水) every five days. Conlon explains that mosquitoes can produce young in water collected in areas as small as bottle caps. But they have a limited flight range, which means they can’t travel far. “The best way to avoid them is to not have them around in the first place.” he says. If you’ve got them in your backyard, it’s because you’re raising them in your backyard. 4.. “If you can’t avoid the standing water around your house, I suggest raising fish that will eat mosquito larvae (幼虫).”
5.. They’ve experimented with male mosquitoes containing some materials that stop females from producing larvae. “There are not a lot of companies producing new chemicals or treatments that we can use,” a researcher of the experiment adds. “We need new technologies and products to get rid of mosquitoes.”
A.They usually provide two hours of protection.
B.Do remember to keep children away from them.
C.So try to make sure your house doesn’t have standing water.
D.You can wear protective clothing and keep your windows closed.
E.You can set up a fan in your house so that mosquitoes can’t bite you.
F.Many people hardly sleep well at night with mosquitoes flying around.
G.The researchers also try to find high-tech solutions to mosquito population.
One of the problems damaging our planet is the number of things we throw away. Rubbish of all kinds is piling up in landfill and polluting our rivers and oceans. A more recent addition to the list of things we throw away is e-waste—electronic items that are broken and not recycled. Now solutions are being found to give this stuff a new life.
Many millions of tons of televisions, phones, and other electronic equipment are discarded each year, partly because it’s cheaper to replace them than fix them, but also because we lack the skills to repair them. A UN report claims the 50 million tons of e-waste produced every year will more than double to 110 million tons by 2050, making it the fastest growing waste stream in the world.
However, there's a growing trend for repair events and clubs which could be part of a solution to the growing amount of electrical and electronic junk. The BBC visited a Restart Project in London, which is one of many found around the world. One of its volunteers, Francesco Calo, said that "this project allows you to reduce waste, make the life of objects longer, and it helps people who cannot afford to get rid of items that have developed a fault. ''
As many electrical items contain valuable metals, another idea is e-waste mining. An experiment at the University of New South Wales involves extracting(提取)these materials from electrical items. It’s thought that doing this could be more profitable than traditional mining. With phones typically containing as many as 60 elements, this could be part of the solution to our appetite for new technology.
These projects make total sense — collection of e-waste for recycling are ''stagnating'' (停滞不前的) or even ''decreasing'' according to Ruediger Kuehr of the United Nations University. And in countries where there is no legislation(立法), much of it is just thrown away. However, the European Union, for example, is trying to deal with the problem by insisting that manufacturers have to make appliances longer-lasting and will have to supply spare parts for machines for up to 10 years.
