Decide which type of software you will use to create a class website. Microsoft has many applications that can be used to create websites, such as Publisher, Word and Expression Web. Some web hosting sites also have simple editing tools you can use instead of a formal program.

Find a place to host your class website. Your Internet provider often provides about some small space for a personal website for free, and many other free website hosting companies are on the Internet.

Consider using a template（模版）for your first attempt at website design. Most templates also come with a selection of color and graphics already in place so you can concentrate on content instead of design. It will contain basic sections with your specific class information.

Add content to your website. You need to have announcement sections for both parents and students, a syllabus or class rules area, homework assignments or a calendar, and maybe a links section for learning more about in-class topics and playing educational games.

Decorate your website with graphics, clip art, background, cool fonts（字体）and other decorative items. It’s best to find a theme you like, such as ducks or fire hydrants, and make your design elements all stick with your theme. If you think that is too attractive, go for an abstract look. Remember to keep it simple since too much color and graphics make a site look busy and detract from its usability.

【题目】The planet is getting greener, and we are responsible. Carbon dioxide generated by human activities is promoting photosynthesis (光合作用) and causing a beneficial greening of the Earth’s surface.

For the first time, researchers claim to have shown that the increase in plant cover is due to this “CO2 fertilisation (肥沃化) effect” rather than other causes. However, it remains unclear whether the effect can reduce any negative effects of global warming, such as the spread of deserts.

To home in on the effect of CO2, Randall Donohue of Australia’s national research institute, the CSIRO in Canberra, monitored vegetation (植被) at the edges of deserts in Australia, southern Africa, the US Southwest, North Africa, the Middle East and central Asia. These are regions where there is plenty of warmth and sunlight, but only just enough rainfall for vegetation to grow, so any change in plant cover must be the result of a change in rainfall patterns or CO2 levels, or both.

If CO2 levels were constant, then the amount of vegetation per unit of rainfall ought to be constant, too. However, the team found that this figure rose by 11 per cent in these areas between 1982 and 2010, mirroring the rise in CO2 emissions (排放). Donohue says this lends strong support to the idea that CO2 fertilization drove the greening.

The extra plant growth could have knock-on effects on climate, Donohue says, by increasing rainfall, affecting river flows and changing the likelihood of wildfires. It will also absorb more CO2 from the air, potentially damping down (抑制) global warming but also limiting the CO2 fertilization effect itself.

Donohue cannot yet say to what extent CO2 fertilisation will affect vegetation in the coming decades. But if it proves to be significant, the future may be much greener.
