The clock tower looks out over a 38-hectare campus graced by an ornamental lake and a pillared central hall. Add a little ivy and it could be almost any respected seat of learning in the West. Only the hemisphere is wrong. This is Ningbo campus of Nottingham University in China’s Zhejiang province, half a world away from its British home. Teaching is in English, the first language of the staff. Last year the college, a joint venture with a Chinese enterprise, opened its doors to 900 local students looking for an international education without leaving home. Within five years their numbers are forecast to reach 4, 000. Say Nottingham University provost Ina Gow: "Why go all the way to Britain when you can study in China at half the price"
Good question. International education is now a global industry worth $ 30 billion a year, with some 2 million students studying abroad, a figure that’s forecast to treble by 2020. In particular,
A. students will choose to study in their own country.
B. Western countries still have strong attraction for students.
C. Australia will surpass the U. S. and Britain in the market share.

Inertial guidance is the name given to those types of systems which guide and keep track of the location of vehicles which are free to move in three dimensions. Vehicles which move only on a plane surface, such as ships or automobiles, require only an accurate compass, sextant, and clock to keep track of their present position. When a vehicle can travel up or down as well as north or east, it is much more difficult to fix its position. An inertial platform is used in inertial guidance to measure vehicle altitude and acceleration which are then integrated to provide position and velocity. The inertial platform consists of three gyroscopes and three accelerometers mounted in the inner gimbal of the four gimbal platform. The purpose of the inertial platform is to allow the vehicle to move in any direction about the inner gimbal containing the gyros and accelerometers, without disturbing or turning them from their original orientation. Thus the gyros and accelerometers do not mm when
A. to provide training information to new pilots and navigators.
B. to motivate people's interest in space travel.
C. to explain how to use an inertial guidance system.
D. to describe the structure and importance of an inertial guidance system.
