People living more than three thousand meters above sea level find it difficult to raise vegetables all year long. People living in the highlands of Peru and Bolivia, for example, cannot grow vegetables outdoors during the months of May through September. It is very cold in the highlands at that time of year. If traditional farming methods are used, vegetables will not survive.
However, there is another way to grow vegetables throughout the year in cold areas. It is a method of gardening developed by a private agency called World Neighbors. The method uses “hot houses” built below ground. A hot house is a building covered with plastic or glass in which vegetables or flowers are grown. The traditional hot house is built above ground.
The air temperature is cold in the highlands of Peru and Bolivia during the winter. But, the winter sun is hot. So, World Neighbors advises farmers there to build hot houses below ground. The design is simple. The material does not cost much. Here is how World Neighbors says to build it: Dig a hole two and one-half meters wide and six meters long. Make it about two meters deep. Build wall with a door in one end of the hole. Dig steps from the ground down to the door.
Now, build a wall along the top edge of the hole. Make it about one-half meters tall. Earth bricks work fine. Build two shorter walls on the ends. These will be uneven; one side will be as high as the existing wall. The other side will be at ground level. Leave a small opening in each of these sloping walls. This prevents the hot house from becoming too hot. Now, make the roof. Build a wood frame. Cover it with clear plastic. Connect it to the brick walls.
The underground hot house we have described is large enough for two raised vegetable beds. Each is one meter wide and six meters long. Each is seeded and watered just as if it were in a garden above ground.
The dirt walls protect the growing plants from the cold. The clear plastic roof permits the sun’s heat to enter. At night, the roof should be covered with straw. This helps prevent cold air from entering. An under ground hot house this size will provide enough vegetables for one family. Groups needing more vegetables can make it bigger.
66. If you lived in Peru, you _______.
A. should raise the special kinds of vegetables that can endure cold
B. could not plant at all
C. had to work out some new unusual plans
D. would not have many vegetables to eat
67. To our surprise, the “hot houses” invented by World Neighbors are _______.
A. covered with a transparent plastic ceiling
B. built under ground
C. quite small
D. hotter than traditional ones
68. The hot house can be kept warm by using _______.
A. a big oven B. an electricity heater
C. the heat of the earth’s interior D. the sun shine
69. The measure to prevent the hot house from becoming too hot is to _______.
A. make the roof sloped B. dig holes on the walls
C. make the wall not vertical D. make the walls shorter than the ground level
70. According to the passage, the method suggested by World Neighbors is _______.
A. new and difficult B. uneasy to explain

Money spent on advertising is money spent as well as any I know of. It serves directly to assist a rapid distribution of goods at reasonable prices, thereby establishing a firm home market and so making it possible to provide for export at competitive prices. By drawing attention to new ideas it helps enormously to raise standards of living. By helping to increase demand it ensures an increased need for labor, and is therefore an effective way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television license would need to be doubled, and travel by bus or tube would cost 20 per cent more.
And perhaps most important of all, advertising provides a guarantee of reasonable value in the products and services you buy. Apart from the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for mercifully the public has the good sense not to buy the inferior article more than once. If you see an article consistently advertised, it is the surest proof I know that the article does what is claimed for it, and that it represents good value.
By the first sentence of the passage, the author means that______.
A. he is fairly familiar with the cost of advertising
B. everybody knows well that advertising is money consuming
C. advertising costs money like everything else
D. it is worthwhile to spend money on advertising
In the passage, which of the following is not included in the advantage of advertising?
A. Securing greater fame. B. Providing more jobs.
C. Improving living standards. D. Reducing newspaper cost.
According to the author, _____.
A. the consumers are often fooled by misleading advertising.
B. no advertiser dare promote a product that can't live up to the promise of his advertisement.
C. if an article is consistently advertised, it probably has good value.
D. with advertisements, you have to pay more for the goods or services you need.
From the passage, we can draw a conclusion that____.
A. the most importance of advertisements is to lower the cost of many services
B. the twenty-seven Acts of Parliament made misleading advertisements unable to exist
C. advertising assists a rapid distribution of goods, thereby do good to the import at good prices
D. advertising does a lot for the material benefit of the community

The best thing you can say about the roofs of most city buildings is that you don’t have to look at them much. That’s very good, since and urban landscape viewed from above can be and unlovely thing－block after block of tarred（铺有沥青的）black rooftops, sticky in summer, windswept in winter, ugly year-round. Or at least that’s the way it used to be.
But urban roofs are going green. Environmental designers have begun to realize that the tops of buildings don’t have to be wastelands. Indeed, they can be gardens, planted with grasses, flowers and bushes.
A planted roof usually comes in one of two varieties: extensive or intensive. The extensive type is wide and shallow, with a soil depth of less than 8 inches, able to support smaller plants, The intensive type may be smaller, but it’s relatively deeper and home to larger plants.
Whatever the design, green roofs are not so simple as ordinary gardens. They have multiple layers beneath the soil, including a drainage layer, waterproofing, structural support, and so on .
But this system can do a great deal of good. A recent paper in the journal BioScience tells that green roofs can control temperature, contain water and clean the air. And most impressively, they can cut heat loss from a building by 50%, lower air-conditioning costs by 25%, and reduce the urban-heated-island effect by 2℃.
Of course, apart from the square feet greened and heat reduced, green roofs are even more valued since people can gain some psychological comfort simply by having a quiet place to go. As so often happens, what’s good for the planet can also be good for the spirit.

Started in 1636, Harvard University is the oldest of all the many colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard.
In the early years, these schools were much alike(*similar).Only young men went to college. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew.
