China’s oil price _____ very sharp increase during the year 2010 and it is continuing to rise further in 2011.

China is going green．In order to reduce air pollution and oil shortages, carmakers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market．Toyota’s hybrid car Prius will be ready to drive in China this week．Let’s have a look at the new car．
Any vehicle is a hybrid run on a rechargeable battery and gas．Hybrid cars have special engines, which are smaller than traditional gas engines．The gasoline engine provides 99 percent of the power when the car is going at a steady speed. A specially designed battery motor provides extra power for running up hills or when it needs to speed up．
Step into a Prius, and turn on the engine．The first thing you notice is that it is quieter than a traditional car．At this point, the car’s gas engine is at rest．The electric motor will provide power until the car reaches about 24km/h．If you stay at a low speed, you are effectively driving an electric car, with no gas being used, and no waste gas given off．
The computer decides when to use the gas engine, when to go electric, and when to use a combination of the two．If you go over 24km/h, when you step on the gas pedal (油门), you are telling the computer how fast you want to go．
The electric motor recharges automatically using a set of batteries．And when driving at a high speed, the gas engine not only powers the car but also recharges the batteries．When you use the brake, the electric motor in the wheels will work like a generator (发电机) to produce electricity to recharge the batteries．As a result, the car’s batteries will last for around 200,000 miles．
66．The underlined sentence probably means ________.
A．there will be more and more green land in China
B．China’s new cars are combinations of different green models
C．China is still young and lacking in experience
D．the environment is getting better in China
67. What is the most important feature of hybrid cars?
A. They are powered by both a rechargeable battery and gas.
B. They have smaller engines than traditional gas ones.
C. They only use 99 percent of their power to run up hill.
D. They are much quieter than traditional cars.
68. We can know from the story that ________.
A. the gas engine recharges the batteries as well as powering the car
B. using the brake suggests that the gas engine should work
C. the car’s batteries will last for around 200,000 miles without being recharged
D. the batteries can be recharged at any time you want
69. The author writes the passage mainly to________.
A. announce plans to develop hybrid vehicles for the Chinese market
B. let people know how to save their gas when driving a car
C. teach people how to drive a hybrid car
D. introduce a new kind of “green” car
70．Which of the following statements is TRUE according to the text?
A．The hybrid car is environmentally friendly．
B．The hybrid car is unable to get itself recharged．
C．The hybrid car has been made in mass．
D．The hybrid car can decide what power to use

Every year there are hundreds of earthquakes in different parts of the world. In September, 1923, Tokyo and Yokohama were both destroyed by an earthquake and the fires that followed it. They had to be completely rebuilt. One of the most serious earthquakes was in China’s Shanxi province in 1556. It killed almost one million people.

We measure an earthquake’s strength on the Richter Scale. The Richter Scale was introduced in 1935 in Southern California in the USA. It measures earthquakes on a scale of one to ten. Any earthquake measuring five or more is usually serious.

The Earth’s crust(地壳) is made up of rock called plates. As these plates move, they sometimes crash against each other, causing the crust to quake. In cities such as Tokyo, where small quakes happen quite often, many modern buildings are designed to be flexible so when the Earth moves, they move with it.

Earthquakes can also break up gas and oil pipes. This can cause fires to break out, which can do as much damage as the earthquake itself. Another effect of earthquakes is tsunamis. These are huge waves created by earthquakes beneath the sea. They can be many meters high and cause great damage to coastal towns and cities, China, Japan, Russia and the USA have the highest occurrence(发生) of earthquakes in the world.

A．can cause earthquakes

B．are caused by earthquakes

C．only happen on land

D．are a way of measuring earthquakes
