第二篇A Very Slow Ride
The surface of the earth may seem very stable to you.But you might be amazed if you knew some of the things that are going on under that surface.
The earth has an outer shell of rigid pieces called tectonic plates (地壳构造板块).The plates include both ocean floor and dry land.Some have whole continents on top of them.The continents on top of the plates are just going along for a slow ride,moving only about four inches per year.But even this small movement causes three types of big interactions.
One type is ocean ridges.These ridges develop in places where two plates are moving away from each other.As the plates separate,hot magma(岩浆)flows up to fill the space.New crust(地壳)builds up on the plate boundaries and causes ocean ridges.These ridges form long mountain ranges,which only rise above the ocean surface in a few places.
Another type of reaction-trenches-occurs between two plates that are moving toward each other.As the plates meet,one bends downward and plunges undemeath the other.This forms deep ocean trenches.The Marianas Trench off Guam in the western Pacific Ocean has a depth of more than 36,000 feet.This is the lowest point on the ocean floor.If the leading edges of the two colliding plates carry continents,then the layers of rock in the overriding plate crumple(变皱)and fold.A plate that carried what is now lndia collided with the southern edge of the plate that carried Europe and most of Asia.This caused the Himalayas,the world’s highest mountains.
The third reaction is transform faults(转换断层).These faults occur where two plates that are traveling in opposite directions slide past each other.Severe earthquakes can occur.The San Andreas Fault in Califomia is a good example of this type of movement.
36.The word“stable”(paragraph 1)means
A.“a place for horses”.
B.“calm and easygoing”.
C.“steady or firm”.
D.“a collection of animals”.

A.the sea floor in the Atlantic Ocean.
B.the Himalayan Mountains.
C.Europe.
D.lndia.
38.The San Andreas Fault is an example of
A.a severe earthquake.
B.a California rock formation.
C.two plates moving apart.
D.two plates aliding past each other.
39.According to the passage,the earth is
A.always changing.
B.becoming smaller.
C.moving faster.
D.getting hotter.
40.This passage is mostly about
A.effects of movements of the earth’s plates.
B.different types of continents.
C.the Marianas Trench.
D.transform faults.
第三篇Mobile Phones:Are They about to Transform Our Lives?
We love them so much that some of us sleep with them under the pillow,yet we are increasingly concerned that we cannot escape their electronic reach.We use them to convey our most intimate secrets,yet we worry that they are a threat to our privacy.We rely on them more than the lnternet to cope with modern life,yet many of us don’t believe advertisements saying we need more advanced services.
Sweeping aside the doubts that many people feel about the benefits of new third generation phones and fears over the health effects of phone masts(天线竿),a recent report clains that the long-term effects of new mobile technologies will be entirely positive so long as the public can be convinced to make use of them.Research about users of mobile phones reveals that the mobile has already moved beyond being a mere practical communications tool to become the backbone (支柱)of modern social life,from love affairs to friendship to work.One female teacher,32,told the researchers:“I love my phone.It’s my friend.”
The close relationship between user and phone is most pronounced among teenagers,the report says,who regard their mobiles as an expression of their identity.This is partly because mobiles are seen as being beyond the control of parents.But the researchers suggest that another reason may be that mobiles,especially taxt messaging,are seen as a way of overcoming shyness.“Texting is often used for apologies,to excuse lateness or to communicate other things that make us uncomfortable,”the report says,The impact of phones,however,has been local rather than global,supporting existing friendships and networks,rather than opening users to a new broader community.Even the language of texting in one area can be incomprehensible to anybody from another area.
Among the most important benefits of using mobile phones,the report claims,will be a vastly improved mobile infrastructure(基础设施),providing gains throughout the economy,and the provision of a more sophisticated location-based services for users.The report calls on govemment to put more effort into the delivery of services by bobile phone,with suggestions including public transport and traffic information and doctors’ text messages to remind patients of appointments.“I love that idea,”one user said in an interview.“It would mean I wouldn’t have to write a hundred messages to myself.”
There are many other possibilities.At a recent trade fair in Sweden,a mobile navigation product was launched.When the user enters a destination,a route is automatically downloaded to their mobile and presented by voice,pictures and maps as they drive.In future,these devices will also be able to plan around congestion(交通堵塞)and road works in real time.Third generation phones will also allow for remote monitoring of patients by doctors.In Britain scientists are developing a asthma(哮喘)management solution,using mobiles to detect early signs of an attack.
41.What does the writer suggest in the first paragraph about our attitudes to mobile phones?
A.We can’t live without them.
B.We are worried about using them so much.
C.We have contradictory feelings about them.
D.We need them more than anything else to deal with modem life.

A.Modern social life relies significantly on the use of mobile phones.
B.Mobile phones make romantic communication more difficult.
C.Mobile phones encourage people to make friends.
D.Mobile phones enable people of different countries to talk without translation.
43.Teenagers have a close relationship with their mobile phones partly because they
A.use text messages more than any other group.
B.are more likely to be late than older people.
C.tend to feel uncomfortable in many situations.
D.take mobile phones as an indication of independence from their parents.
44.It is suggested that mobile phones should be used to
A.give the address of the nearest hospital.
B.show bus and train timetables.
