Writing a summary

Ⅰ.阅读理解

Some hot dog lovers may feel guilty when they enjoy their favorite food.They even exercise excessively (过分地) to burn off calories afterward.Now they can relieve the pain.A company in Norway develops a product made from trees.It can replace fat in foods like hot dogs but has no calories.

A product named SenseFi is introduced to the public by a Norwegian biorefinery company, Borregard.Though its taste and feel are similar to those of fat, no calories are contained in it.

The material used to create this product is microfibrillated cellulose (MFC), which is a waste product that trees produce when they are cut and prepared for use.Every year there is over a hundred billion tons of cellulose (纤维素) produced by plants, among which only a small part is now useful to humans.

According to a report from the Norwegian daily newspaper Dagbladet, Borregard has spent $36.3 million on developing SenseFi.This project went through a 10­year study conducted by the Paper and Fibre Research institute in Trondheim, Norway.It successfully entered the US market and the company opened a plant in Wisconsin.The food industry there was expected to embrace the arrival of SenseFi.

The company is speaking highly of this product for its incredible effect on fighting against obesity (肥胖)．“We're rolling it out primarily in the US, where it has been approved.Sales are just about underway, and there is a lot of focus on fighting obesity，” said the company's Business Director Harald Ronneberg.

Data from the Centers for Disease Control and Prevention shows that about 40 percent of adults are overweight, and in 2008, the cost of medical treatment of obesity was $147.

With the help of SenseFi, meat used for making foods like hot dogs can be recreated.Not only does it keep the flavor of fat, but it also reduces calorie intake while providing the body with more fiber, which helps people fill themselves up and digest more effectively.

Ⅲ.概要写作

阅读下面短文，根据其内容写一篇60词左右的内容概要。

A well­developed class website can save teachers a lot of time in the long run, improving both student­teacher and parent­teacher communication while providing a place to store all class documents for future use.Although some extra time during the school year  is required, once the site is set up it needs just minor adjustments each new year.Have a question？Get an answer from online technology support now.

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 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 some small space for a personal website for free, and many other free website hosting companies are on the Internet.

Consider using a template  (模板) for your first attempt at website design.Most templates also come with a selection of colour 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 link section for learning more about in­class 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 and make your design elements all match your theme.Remember to keep it simple since too many colours and pictures make a site look busy and weaken its usability.
