Mobile phones should be banned from cars altogether, according to Dr Hole, senior lecturer in psychology, Dr Hole has emphasized the worrying combination of mobile phones and cars in his new book, The Psychology of Driving.
Mobile phones, fatigue(疲劳) , eyesight, drugs and age are among the issues considered by Dr Hole as he examines the factors that influence on driving. The book explores the role of each of these elements in increasing the chances of an accident and was inspired by the author's conversations with road safety experts across the country.
He says: “The government should have banned mobile phones in cars altogether. It has sent out the wrong message by forbidding hand-held phones because this gives the impression that hands-free phones are safe. The problem with mobile phones is not vehicular(车辆的) control and only having one hand on the wheel, but rather it is taking away attention from what is happening outside the car.”
Myths(荒诞的说法) about older people making worse drivers and claims(说法) about an improved reaction time among younger people are explored in the book. Questions about how drivers decide what to attend to while driving, the role of a driver's expectations in determining what they see and how they respond to the road are among the areas covered in the book. Satellite navigation systems and new design aimed at transforming cars into a mobile office, are among the modern developments which he says now compete for driver's attention behind the wheel.
Dr Hole says: “We need to be very careful about how we go about handling modern technology in cars, because we are opening a Pandora's Box. When anyone is driving there is a lot of information outside the car and if there is too much going on inside, then there is a danger of overloading the driver.”

Trees are useful to man in three important ways: They provide him with wood and other products; they provide him shade;. and they help to prevent droughts（早灾）and floods.
Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important．In his eagerness to make money from trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And besides, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even more serious: for where there are trees, their roots break up soil allowing the rain to sink in and also bind（固定）the soil, thus preventing it from being washed away easily；but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When the top-soil is gone, nothing remains but worthless desert.
Two thousand years ago，a rich and powerful country cut down its trees to build warships, with which to gain itself an empire(帝国）．It set up the empire, but, without its trees, its soil became poor and grew weak. When the empire fell to pieces, the home country found itself faced by floods and starvation（饥荒）．

A. many trees have been cut down by man B. man has not paid enough attention to planting trees

A. roots of trees break up the soil B. there are too many rainfalls
C. there are no larger trees to keep rain and protect the top-soil D. strong winds bring a lot of sand
4.The country mentioned in the passage suffered from floods and starvation because________.
A. it set up an empire B. the empire fell to pieces
