Many cities around the world today are heavily polluted. Careless methods of production and lack of consumer demand for environment friendly products have contributed to the pollution problem. One result is that millions of tons of glass, paper, plastic, and metal containers are produced, and these are difficult to get rid of.

However, today, more and more consumers are choosing “green” and demanding that the products they buy should be safe for the environment. Before they buy a product, they ask questions like these: “Will this shampoo damage the environment?” “Can this metal container be reused or can it only be used once?”

A recent study showed that two out of five adults now consider the environmental safety of a product before they buy it. This means that companies must now change the way they make and sell their products to make sure that they are “green”, that is, friendly to the environment.

Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry labels to show that the product is green. Some companies have made the manufacturing (生产) of clean and safe products their main selling point and emphasize it in their advertising.

The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the public accept the old attitude of “Buy it, use it, throw it away, and forget it”. The public pressure is on, and gradually business is cleaning up its act.

1.It is clear from the text that the driving force (动力) behind green products is____.

A. public caring for the environment                   B. rapid development of companies

C. new ways of doing business                          D. rapid growth of supermarkets

2.The underlined word “it” in Paragraph 4 refers to_________.

A. the selling point                              B. the company’s product

C. a great demand for healthful goods              D. the manufacturing of green products

3.What would be the best title for the text?

A. Business and people                            B. Shopping Habits Are Changing

C. Business Goes Green                                   D. Supermarkets and Green Products

Today, bicycles are elegantly simple machines that are common around the world. Many people ride bicycles for recreation, whereas others use them as a means of transportation. The first bicycle was invented in Germany in 1818. Because it was made of wood, it wasn’t very strong nor did it have pedals (脚踏板）.Riders moved it by pushing their feet against the ground.

In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, invented a much better bicycle. Macmillan’s machine had iron-covered wheels to keep them from getting worn down. He also used foot-operated levers, similar to pedals, so his bicycle could be ridden at a quick pace. It didn’t look much like the modem bicycle, though, because its back wheel was substantially larger than its front wheel. Although Macmillan’s bicycles could be ridden easily, they were never produced in large numbers.

In 1861, Frenchman Pierre Michaux and his brother Ernest invented a bicycle with an improved pedal mechanism. They called their bicycle a velocipede，but most people called it a “bone shaker” because of the effect of the wood and iron frame. Despite the impolite nickname, the velocipede was a hit. After a few years, the Michaux family was making hundreds of the machines annually, mostly for fun-seeking young people.

Ten years later, James Starley , an English inventor, made several innovations that revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient，and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top-heavy，and ridden mostly for entertainment.

It wasn’t until 1874 that the first truly modern bicycle appeared on the scene. Invented by another Englishman, H. J. Lawson, the safety bicycle would look familiar to today’s cyclists. The safety bicycle had equal-sized wheels, which made it easier to ride. Lawson also attached a chain to the pedals to drive the back wheel. By 1893，the safety bicycle had been further improved with air-filled rubber tires, a diamond-shaped frame, and easy braking. With the improvements provided by Lawson_; bicycles became extremely popular and useful for transportation. Today, they are built, used, and enjoyed all over the world.

1.This passage was most likely written in order to _____.

A．compare bicycles used for different purposes

B．describe the problems early bicycle makers experienced

C．persuade readers to use bicycles for transportation

D．tell readers about the early history of the bicycle

2.Macmillan covered the wheels of his bicycle with iron to _____

A．add weight to the bicycle

B．make the bicycle easier to ride

C．allow the wheels to last longer

D．let the bicycle be more comfortable

3.Which of the following bicycle types was invented by James Starley?

4.Which of the following statements is true according to the passage?

A．Two hundred years ago，bicycles did not exist.

B．The first bicycle could be ridden at a very quick pace.

C．The Michaux brothers called their bicycle a “bone shaker”.

D．Macmillan’s machine had wheels with rubber tires.

5.The information about bicycles in this passage is arranged according to _____.

A．importance        B．time              C．place             D．Interest

American cities are similar to other cities around the world: American cities are changing, just as American society is changing. After World War Two, the population of most large American cities decreased; however, the population in many Sun Belt cities increase. Los Angeles and Houston are cities where population shifts (转移) to and from the city reflect the changing values of American society. In the late 1940s and early 1950s, city residents became wealthier. They moved out of their apartments in the city to buy their own homes. They bought houses in the suburbs.

Now things are changing. The children of the people who left the cities in the 1950s are now adults. Many, unlike their parents, want to live in the cities. They continue to move to Sun Belt cities and older ones of the Northeast and Midwest. Many young professionals are moving back into the city. They prefer the city to the suburbs because their jobs are there; or they just enjoy the excitement and possibilities that the city offers.

This population shift is bringing problems as well as benefits. Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent. In the 1950s, many poor people did not have enough money to move to the suburbs; now many of these same people do not have enough money to stay in the cities.

Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright, new future. Others see only problems and conflicts. One thing is sure: many dying cities are alive again.

3.According to the 4^th paragraph, a great many poor people in American cities ________ .

4.We can conclude from the text that ________ .
