第1题

Google, the Internet search-engine company, has announced it will give more than twenty-five million dollars in money and investments to help the poor. The company says the effort involves using the power of information and technology to help people improve their lives. Aleem Walji works for Google.org -- the part of the company that gives money to good causes. He said the company’s first project will help identify where infectious (传染性的) diseases are developing. In Southeast Asia and Africa, for example, Google.org will work with partners to strengthen early-warning systems and take action against growing health threats. Google.org’s second project will invest in ways to help small and medium-sized businesses grow. Walji says microfinance (小额信贷) is generally small, short-term loans that create few jobs. Instead, he says Google.org wants to develop ways to bring investors and business owners together to create jobs and improve economic growth. Google.org will also give money to help two climate-change programs announced earlier this year. One of these programs studies ways to make renewable (再生的) energy less costly than coal-based energy. The other is examining the efforts being made to increase the use of electric cars. The creators of Google have promised to give Google.org about one percent of company profits and one percent of its total stock value every year. Aleem Walji says this amount may increase in the future. 问题：The purpose of Google’s investments is to ________.A.help poor people

B.develop new technology

C.expand its own business

D.increase the power of information

According to Aleem Walji, the company’s first project is to ________.A.set up a new system to warn people of infectious diseases

B.find out where infectious diseases develop

C.identify the causes of infectious diseases

D.cure patients of infectious diseases

What kind of businesses will benefit from Google.org’s second project？A.large enterprises

B.cross-national companies

C.foreign-funded corporations

D.small and medium-sized businesses

From the fourth paragraph, we learn that Google’s money is also invested to help ________.A.start more research programs

B.make more advanced electric cars

C.develop renewable and coal-based energy

D.conduct studies related to climate changes

From the last paragraph we learn that the investments by Google.org come from ________.A.Google’s profits and stock value

B.some international IT companies

C.the company’s own interests

D.local commercial banks

第5题

You type a word or phrase into an Internet search engine such as Google or Yahoo, hit return and in an instant, dozens of "hits" -Web sites containing words that match your query-appear on the computer screen. Now imagine a similar database that operates not with words but with shapes, specifically, leaf shapes. It would work like this: carry a camera cell phone into a forest, pick a leaf from a tree and snap its

portrait. [1] In an instant, the phone transmits the image to a computer that matches a shape of the leaf

against a database of leaf shapes from thousands of plant species around the world. Exact matches for the leaf are returned to the screen of your phone along with species names and detailed botanical information. Sound farfetched？ Such a device is already very close to reality, thanks to recent collaboration between the department of botany at the Smithsonian&39;s National Museum of Natural History and the computer science departments of Columbia University and the University of Maryland. [2] Tentatively called the Image Identification System or IIS, the invention has the potential to revolutionize the identification of plant species in the field and greatly accelerate the naming of new plant species.

[3] For Peter Belhumeur, a computer scientist at Columbia University, who studies the use of computer vision to identify human faces, it all started years ago in the Connecticut woods. Belhumeur recalls just how hard it was to use a standard field guide to identify different tree species during walks with his children. "I rarely found the right answer on the first try," he says. Brainstorming with computer scientist David Jacob of the University of Maryland about possible new uses for computer object recognition, "We both thought of leaves," Belhumeur recalls. So in 2001, [4]Belhumeur and Jacobs came to visit John Kress, Director of the Natural History Museum&39;s Botany (植物学) Department, which house the national plant specimens, a resource with 95,000 catalogued botanical type specimens ----the definitive reference specimens used to identify new plant species ---- and an additional 4.8 million representatives of plant species from around the world.

[5] What the scientists came up with was an ambitious plan to develop an electronic field guide---- a

portable system that could automatically identify a tree species from the shape of one leaf. They wanted the device to simultaneously provide researchers in remote locations Internet access to botanical data on species in the Smithsonian&39;s database.
