The marine environment is fascinating to study and work in due to its beauty, richness, and complexity. It covers three quarters of the surface of the Earth, yet we know more detail about the surface of Mars.

In the past, it was seen as both an inexhaustible resource and a bottomless sink for our wastes. Yet the increasing pressures of overpopulation, pollution and the threat to our natural environment mean that there is an increasing need for scientists who can understand how it all works, how it affects us, and how we are affecting it from global warming through to the smallest plankton.

From local issues to global concerns, we now know that the marine environment is inextricably linked to our lives, and to our future survival. It is an area where much remains to be discovered, and where only a multidisciplinary approach can cover the breadth of issues to be confronted. This is the approach taken on our Marine Environmental Science degree course.

This course takes a multi-disciplinary approach to explore and understand the marine environment. After an initial grounding in basic science, optional choices are available in specialist topics such as marine ecosystems and pollution, coastal navigation and oceanography, among others.

Our new harbor side marine laboratory is used for some of the specialist lectures, laboratory and project work, while a week's residential field course in the Isle of Man provides training to prepare for the research project conducted in your final year. There is an optional trip to Belize in the final year to study tropical marine environments.

From the passage, we can infer that ______.

A. people waste a lot of resource

B. marine environment covers 3/4 of the surface of Mars

C. marine environment is beautiful for its sufficient resources

D. the Earth is similar to Mars

The present environment of the Earth forces the experts and scholars to study ______.

A. the relationship between people’s actions and natural environment

B. the relationship between people’s actions and pollution

C. the relationship between people’s actions and overpopulation

D. the relationship between people’s actions and plankton

According to the passage, a multi-disciplinary approach is effective because _______.

A. we can choose some issues as optionally as we can

B. we have practiced the approach for a long time

C. the approach is linked to our future survival

D. the approach covers a lot of problems we will meet

We can divide the lectures of the course into ______ parts.

A.1       B. 2       C. 3       D. 4

If a student choose marine Environmental Science degree course, he must ______.

A. make lectures about the issues to be confronted

B. provide training to get ready to do research project

C. take several days residential field in the Isle

We each have a memory（記憶力）. That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got surprising memories.
A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
