It's important to learn how we can protect the environment. Here are 5R rules for us.

Reduce. If you want to reduce waste, you should use things more wisely.1. If everyone uses paper carelessly, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the amount of waste we produce.

Reuse. You should always think of reusing things before throwing them out. For example,2.. In a family, you may pass on such clothes to younger brothers or sisters.

Recycle. Bottles, cans and paper can easily be recycled. By doing so we can save lots of time and money. For example,3.. The metal can be used to make new coke cans.

Recover.4.. You have two choices: one is to throw the apples away, the second is to throw the rotten ones and keep the good ones. In this way, you are recovering the eatable parts of food.

Repair. If one of the legs of your table is broken, you should repair it. If you want to buy something newer and better, it is better for you to sell the old table, or 5.

高一英语单词拼写简单题查看答案及解析

We must do what we can to protect the plants because plants are very important for living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.

If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）. Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.

高一英语单项填空困难题查看答案及解析

Clearly if we are to participate in the society in which we live, we must communicate with other people. A great deal of communicating is performed on a person-to-person basis by the simple means of speech. If we travel in buses, buy things in shops, or eat in restaurants, we are likely to have conversations where we give information or opinions, receive news or comment, and very likely to have our views challenged by other members of society.

Face-to-face contact is by no means the only form of communication and during the last two hundred years the art of mass communication has become one of the dominating factors of contemporary society. Two things, above others, have caused the enormous growth of the communication industry. Firstly, inventiveness has led to advanced imprinting, telecommunications photography, radio and television. Secondly, speed has revolutionized the transmission(传输) and reception of communications so that local news often takes a back seat to national news, which itself is often almost eclipsed(侵蚀) by international news.

No longer is the possession of information confined to(只限于) a privileged minority. In the last century the wealthy man with his own library was indeed fortunate, but today there are public libraries. For years ago people used to flock to the cinema, but now far more people sit at home and turn on the TV to watch a programme that is being channeled into millions of homes.

Communication is no longer merely concerned with the transmission of information. The modern communication industry influences the way people live in society and broadens their horizons by allowing access to information, education and entertainment. The printing, broadcasting and advertising industries are all involved with informing, educating and entertaining.

Although a great deal of the material communicated by the mass media is very valuable to the individual and to the society of which he is part, the vast modern network of communications is open to abuse(滥用). However, the mass media are with us for better, for worse, and there is no turning back.

1.In the first paragraph, the writer emphasizes the ___________ of face-to-face contact in social setting.

A. nature　　　　 B. limitation　　　　 C. creativity　　　　 D. usefulness

2.It is implied in the passage that ______.

A. local news used to be the only source of information

B. local news still takes a significant place

C. national news is becoming more popular

D. international news is the fastest transmitted news

3.Which of the following statements is NOT true?

A. Possessing information used to be a privilege.

B. Public libraries have replaced the private completely.

C. Communication means more than transmission of information.

D. Information influences ways of life and thinking.

4.From the last paragraph we can infer that the writer is _________.

A. indifferent to the harmful influence of the mass media

B. happy about the flexible changes in the mass media

C. pessimistic about the future of the mass media

D. concerned about the wrong use of the mass media
