The Hubble space telescope has earned its place in history. US astronomer Lyman Spitzer first proposed a space observatory in 1946. It was a bold idea then, considering that no one had yet launched so much as a rocket out of the Earth's atmosphere. But he was aware that such a telescope would produce clearer images than ground-based telescopes because although we are fortunate to be blanketed by an atmosphere that protects us from the radiation of outer space, that same atmosphere also causes the images of all celestial objects to be blurred. While we see this distortion as the familiar twinkling of stars in the night sky, astronomers see only a headache in trying to analyze the heavens.

It was a very narrow street of tall, diseased houses that leant towards one another strangely, as though they had all been frozen in the act of collapse. All the houses were hotels and packed with lodgers, mostly Poles, Arabs and Italians__outsiders like myself. At the foot of the hotels were tiny cafés, where you could be drunk virtually for free. On Saturday nights, about a third of the male population of the quarter was drunk. There was fighting over women, and the Arab labourers who lived in the cheapest hotels used to conduct mysterious feuds, fighting sometimes with chairs and sometimes with pistols. At night, two policemen would rush frightened through the streets before leaving. It was a fairly noisy place, and yet amid the noise and dirt lived the usual respectable French shopkeepers, bakers, laundresses and so on, all minding their own business and quietly piling up small fortunes. It was quite a representative Paris slum.

The Altair 8800, the first home computer, launched by research engineer Ed Roberts in 1975, didn't actually do much as a computer. It had neither a screen, nor a keyboard, nor any software. But it did fill a hole in the market: it was the very first personal computer to be produced in fairly high quantity. The larger computer companies were busy developing mainframes and improving computer systems for industrial applications, and couldn't really see why anyone would want a home computer. They also failed to see the implications of the newest microprocessors, which were both small and cheap.
- The passage implies that the Altair 8800 was successful because ___________.
- As is pointed out in the passage, __________.
- It is pointed out in the passage that in 1975 the large computer companies ___________.
A major Chinese poet during the Tang Dynasty (618-907), Li Po was born in 701 in Sichuan Province in southwestern China. A romantic at heart, he left home to wander the country at the age of 19, and it was at this time that he began writing poems. His poetry is concerned with the joys of nature, love, friendship, solitude, and wine. He married after a few years and settled down temporarily with his wife's family, while attempting unsuccessfully to use his poetry to gain an official position in the Chinese government. After many more years of wandering, in 757 Li Po joined an expedition, led by one of the emperor's sons, to put down a rebellion in southern China. Accused afterwards of trying to set up an autonomous kingdom, the prince was arrested and executed. Li Po was jailed for a time and then released. He died in 762.
