The first bullet "train designed and manufactured in China with a speed of 300 kilometers per hour roiled off the production line on Saturday morning. The train was the latest model in the country' s China Railway High-speed (CRH) Series. This marks that China has joined a leading world club after Japan, France and Germany to become the fourth country capable of turning out such high speed trains. Previously, China' s fastest selfdeveloped trains ran at a service speed of up to 250 km per hour.
Those trains, which presented to public on April 18, served the Beijing-Harbin, Beijing-Shanghai and Beijing-Guangzhou routes. The new streamlined train was made of aluminum alloy(铝合金). The train body was the lightest of its kind in the world; Such a design was for the sake of energy economization. The train' s power was 12.7 kilowatts, lower than other high-speed trains, which was normally about 15 kilowatts.
The new train, which features a bar in the dining car and double-faced LCD TV screens in the first-class cars, was equipped with shock absorbers between carriages. As the train is running at a high speed, the shock absorbers are used to reduce shocking force and rocking of the train body. A train with eight carriages could seat about 600 passengers. They were expected to run on the 115-km Beijing-Tianjin route starting from August before the Beijing Olympic Games. It would reduce the journey time from the current 80 minutes to around 30 minutes.

Every year mobile phones develop. Imagining what they will look like and be able to do in 2020 is really a challenge. To help, experts have outlined three major mobile trends that they believe will have become reality by then.
Our phones will be so smart in 10 years’ time that they’ll know everything about our situation and warn us when something needs our attention. This is the top prediction of both Nokia and Google. They predict that our cars and home appliances will be able to communicate with our mobile. For example, fridges will tell your mobile to tell you to pick up milk on the way back from work. While driving, your mobile will suggest that you take a different route because there’s a road accident up ahead.
The second trend is in gesture-based controls. People who know the iPhone’s touch-sensitive screen are already familiar with the technology. It translates hand movements into actions on-screen. But gestural communications will make the phone more convenient to use and may completely replace touchpads. According to industry insiders, the most immediate step forward in gestural technology will be in voice recognition. It’s believed voice recognition technology will speed up communications. It is quicker to speak than type. Eventually, phone screens will disappear.
The third major development will change our understanding of a mobile phone. From a single phone, the mobile will be developed into multi-part devices. It is opposite to the current trend in which mobile phones are combining the functions of cameras, music players and game consoles. The prediction is based on the idea that the world will become more wireless and all these—cameras, music players and game consoles—will be wirelessly connected. Mobile phones won’t need to contain these devices because users will be able to control them wirelessly through their phones.
