[单项选择]High speed was one of the factors causing the deadly train disaster in Zibo, Shandong Province, Xinhua said on Tuesday.
The Monday train collision killed at least 71 and injured 416 others by the time of press. It occurred when a passenger train from Beijing derailed and collided with an oncoming train on the Jinan- Qingdao line. Xinhua reported that the train from Beijing was traveling at 131 kilometers an hour, in excess of the 80-kilometer-an-hour speed limit, before it came off the tracks.
Authorities had on Monday ruled out terrorism and said "human error" was to blame.
In 2006, China made up a quarter of the world’s total railway transport volume, while its track length only made up six percent of the world’s total, according to the Ministry of Railways.
On such busy tracks, a small error can cause chaos. The Zibo accident is the worst in China since 1997 when 126 people were killed in Hunan Province.
That year coincided with the decision to rai
A. A passenger train from Beijing was traveling at 80 kilometers an hour.
B. The decision to raise train speed limits.
C. Social unrest.
D. Human errors.

High-speed Internet connectivity still is an elusive luxury for most Indians: with just over a million broadband subscribers in a country of more than one billion people, only the best off in the big cities can take advantage of it. But WiMax, the IEEE standard for wide area wireless broadband connectivity, could be coming to the rescue. It offers India the prospect of largely skipping connections to the Internet by the DSL links and ca- ble modems that are standard in so many other places.
A number of recent developments suggest that WiMax might offer the best answer to last-mile broadband connectivity in a country like India--or at least that lots of corporate leaders are thinking the same way. For example, Videsh Sanchar Nigam Ltd. (VSNL), a leading international telecom service provider headquartered in Mumbai, already has deployed WiMax infrastructure in 65 Indian cities, relying on equipment made by Aperto Networks, in Milpitas, Calif. Aperto is a leading developer
A. Currently still not many Indians have access to high-speed Internet connectivity.
B. Wireless broadband connectivity might be an answer to India’s problem.
C. A majority of Internet users are finding wireless broadband very helpful.
D. An international telecom service provider has already deployed WiMax infrastructure in 55 Indian cities.
[简答题]High-speed ground transportation (HSGT) technologies with vehicle speeds exceeding 150 mph can be divided into two basic categories: High-speed rail (HSR) systems, with top speeds between 150 and 200 mph, use steel wheels on steel rails, as with traditional railroads, but can achieve higher speeds because of the design of both the rail bed and cars. High-speed magnetic levitation (MAGLEV) systems, with top speeds between 250 and 300 mph, use forces of attraction or repulsion from powerful magnets placed in either the vehicle or the guideway beneath it both to lift the vehicle above the guideway and to propel it forward. A MAGLEV vehicle can be likened to a flying train or a guided aircraft. If linked effectively with highways and air service, HSGT technologies-particularly MAGLEV—could have a significant impact on congestion in the future. When comparing HSR with MAGLEV technologies, MAGLEV appears to be the technology of choice. Though the new generation of HSR technology can reach co

If an agreement signed in Germany works out,travellers of this Asian city may one day be able to zip from the downtown area to its new airport on a train riding a stream of magnetic energy at speeds up to 500 kilometres per hour.
The 40-kilometres-trip-now sometimes a long hour journey when the traffic is heavy-could be cut to less than 10 minutes.
Such are the goals of a costly project designed to help to "shorten’the distance between the city centre and the suburban busy airport by making it easier and faster to carry travellers to and back from the airport.
The mayor of the city and Germany’s Thyssen Krupp AG worked out an agreement in Berlin only several days ago that lays the groundwork for the magnetic levitation train line. They signed a commitment to carry out a feasibility study on the project and outlined the city’s intention to import German technology. This project,once completed
A. The mayor.
B. Both the German ambassador and the mayor.
C. The German ambassador.
D. The representative from the German company.
