The UN passed a rule in the year 2004 to improve the quality of drink water and reduce deaths caused by drinking unhealthy water each year. The UN has already worked out the specific plan to reduce half of the number, that is, five thousand. The UN announced in the world there are about 1/6 of the world population can't meet the sanitation regulation of drinking water.

The water we drink and use is running short in the world. We all have to learn to stop wasting our quite limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done on this field. Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying(凈化)factory. There it can be filtered(過濾) and treated with chemicals so that it can be used again , just as it were fresh from a spring. But even large cities purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we would have to do to make use of seawater on earth is to get the salt out of it. This method has already been used in many parts of the world.

To Whom It May Concern:
On March 5, 2012 , I bought a Perfect Muffin Kit from your store at Midfield Shopping Center. The cashier who assisted me was George. George was very friendly and told me that the Perfect Muffin Kit would live up to the guarantee on the box: “Perfect Muffins Every Time!”.
Unfortunately, this product did not live up to what it promised . The muffins I made were far from perfect . I followed the directions in the package very carefully . First , I removed the bag of mix from the box. Then , I poured it into a bowl. Next, I added the correct amount of water to the mix and stirred it. According to the directions, after stirring the mixture , I added half a cup of dried grapes, nuts , berries, or another favorite ingredient . My favorite ingredient happens to be hot sauce . I find that a bit of hot sauce makes pizza and soup taste very delicious. So, continuing to follow the directions, I added half a cup of hot sauce to the mix and stirred it. Finally, I poured the mix into muffin tins and baked it in the baker at 350 degrees for exactly 20 minutes.
When the muffins finished baking, I was very excited to eat the “Perfect Muffins” as promised on the box. You can imagine my disappointment when, upon tasting the muffins, I discovered that they were not perfect. These muffins were , in fact , absolutely terrible. Not even my dog was interested in eating these supposedly “perfect” muffins.
I would appreciate a full refund( money to be returned) of $3.99 for this product as soon as possible. Enclosed are the receipt, the empty box, and one of the un-perfect muffins so that you can experience it for yourself . Thank you for your attention to this matter.
Sincerely,
Michelle Bauer

Hundreds of students from around the world gathered in New York City last week for the Microsoft Imagine Cup finals. They came to present their ideas for using technology to solve world problems.

Microsoft education director Suzi Levine says the nine-year-old program began mainly as a competition to create technology.

SUZI LEVINE: "When we realized that students really actually want to have a purpose for what they're creating, we introduced the idea of inspiring them with the UN Millennium Development Goals and suggesting that they use those for their muse(靈感). "This past year we also rolled out something called the Imagine Cup Solve This library(創(chuàng)新杯求解計劃知識庫), where IGOs, NGOs and nonprofits can submit some of the technical challenges that they would like students to consider for their solutions."

Microsoft says over 350,000 high school and college students registered for this year's competition. Judges chose more than four hundred of them to attend the finals.

 SUZI LEVINE: "One from Thailand was called NewKrean, where they created a Windows Phone 7 application that allows you to broadcast your location to your social network of friends so that you can be more easily rescued." They named their application Terra.

Suzi Levine says there were also ideas from Egypt inspired by the revolution that overthrew president Hosni Mubarak in February.

SUZI LEVINE: "One was to use Bluetooth as sort of a Twitter equivalent so that if the government shuts down the Internet, you actually can still have a massive social distribution."

Students competed in nine categories. For example, in software design the top prize of twenty-five thousand dollars went to Team Hermes from Ireland. The students developed a device for cars to collect information on road conditions, driving behavior and traffic incidents.

A team from Taiwan's National Tsing Hua University won first place in the embedded(內(nèi)嵌的) development category. They developed a network of wireless devices to help plot the safest escape routes during a fire.

Next year's awards ceremony will take place in Australia. Registration for Imagine Cup twenty-twelve opened Friday. Also, Microsoft announced plans for a three million dollar program to help Imagine Cup winners further develop their projects.

1.Which of the following is true ?

A. The program is sponsored by Microsoft.

B .Next year, the awards ceremony will be held in New York City.

C. Any high school or college student can attend the finals.

D. The initial purpose of the program is to solve world problems using technology.

2.What can we infer from the third paragraph?

A. The UN offers great help to the program.

B. Microsoft sets up a library for the students who want to achieve their goals.

C. IGOs, NGOs and nonprofits also provide help for the students.

D. Microsoft takes effective measures to inspire the students.

3.What does the underlined word “overthrew ” in Paragraph 6 mean ?

A. Abandoned    B. Supported        C. Drove away        D. Overturned

4.What can we know from Paragraph 7?

A. They want to replace Bluetooth with Twitter.

B. They want to combine Bluetooth with Twitter.

C. They want to replace Twitter with Bluetooth.

D. Twitter can still be used without the Internet.
