In the late 1970’s,many people in North America turned their attention to environmental problems ，and new steel — and — glass skyscrapers were widely criticized. Some ecologists (生态学家）pointed out that a number of tall buildings in a city often overburden public transportation.
Skyscrapers are also lavish consumers of electric power and water. In just one recent year, the addition of 17 million square feet of skyscraper office space in New York City itself has already raised the top daily demand for electricity by 120, 000 kw — enough to supply the entire city of Albany in New York area for a single day.
Glass—walled skyscrapers can also be especially wasteful. The heat loss ，or gain， through a wall of half 一 inch plate glass is more than ten times that through a typical ordinary wall filled with bricks or board. In order to decrease the pressure on heating and air — conditioning equipment, builders of skyscrapers have begun to use double—layered glass ，and reflective glasses coated with silver or gold mirror films that could reduce glare (强光）as well as heat gain. However, mirror — walled skyscrapers may raise the temperature of the surrounding air and affect neighboring buildings as well.
Skyscrapers put a severe pressure on a city's sanitation (卫生）facilities, too. If fully occupied, the towers just within the central area of New York would alone produce 2. 25 million gallons of waste water each year^—as much as the city size of Stanford， Connecticut, which has a population of more than 109，000.
63.The underlined phrase“ lavish consumers ”in the 2 paragraph probably means ____ A. trash producers B. great spenders C. pressure makers D. poor customers 64.Glass walls of skyscrapers are specially mentioned in order to _____.
A. show how skyscrapers manage to lessen their pressure B. explain why skyscrapers can control its air conditions C. describe further how wasteful skyscrapers could be D. present the stability of skyscrapers in modern buildings 65.From the last paragraph we can learn that _____.
A. central New York skyscrapers are a large waste water producer B. the central area of New York is as large as the city of Stanford C. more than 109，000 people live in the skyscrapers in New York D. New York produces 2. 25 million gallons of waste water each year 66.When the writer talks about skyscrapers ，his tone sounds _____
A. positive
B. doubtful
C. grateful
D. negative

Yawning sends out certain messages -either “Oh ，this movie is so boring” or “I probably need to get some sleep”. But did you know that a yawn can also help your brain to cool down when it is overheated?
A new study, led by a research team at Princeton University, has indicated that yawning could be the brain’s natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily. com.
The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.
When people yawn, their jaw is also stretched ，which increases blood flow and may also help cool the brain
The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawned. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.
However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.
According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease. 67. The purpose of the experiment is ______.
A.to find the frequency of people’s yawning
to indicate brain can regulate temperature naturally B.
C. to prove people yawn in winter and in summer equally to show the real reason why people yawn D.
68.The information we get from Paragraphs 5 and 6 is that ______.
longer outdoor summertime results in more yawns A.
B. yawning frequency increases with outdoor time yawning frequency changes with outdoor time C.
longer outdoor wintertime leads to fewer yawns D.
69. Acorrding to the text，people yawn more often ______.
when the air temperature is equal to the body A.
when the hot air breathed in makes the brain hotter B.
C. when the air temperature is higher than the body D. when the air temperature is lower outside the body 70. What could be the best title for the text?
Yawning Is A Sign of Brain Disease A.
B.Yawning Cools Your Brain Yawning Benefits Your Body C.
D. Yawning Carries Some Information

A long red bridge stretches out across water. It runs across the Golden Gate. This is not the entrance to some sacred (神圣的）land，but it is just as magical. The Golden Gate is where San Francisco Bay meets the Pacific Ocean, and at night the scene of the bridge lit up over the water takes your breath away.
Welcome to San Francisco, a place famous for its beautiful parks, hilly streets and lovely beaches. But the bridge is undoubtedly the most well-known symbol of the city. Before its completion in 1937, the bridge was considered impossible to build because of the foggy weather ，powerful winds, and strong ocean currents (洋流)in the city. However, despite the difficult conditions, the bridge was built in no more than four years. Its total length is nearly 2 kilometers.
San Francisco ranks first on Lonely Planet’S list of best cities to visit in 2013. According to the world’s largest travel publisher, it came top as a result of its cultural mix.
According to the US 2010 census (人口普查），21 percent of the city’s population is made up of Chinese people. San Francisco’s Chinatown is the largest outside of Asia and the oldest in North America. Two traditional festivals, the Spring Festival and Mid-Autumn Festival, are the biggest events of the year on the city’s calendar.
If yellow cabs (出租车）are a key part of New York city life, then the cable car (缆车） is San Francisco’s equivalent. The first cable car came into public service in 1873, and the slow and noisy vehicle has been a symbol of the city ever since. The cable car network was once damaged by a serious earthquake but, luckily, it has now recovered and provides better views than the subway. 71. What makes the Golden Gate Bridge so famous?
