Task 1
【答案】
1) b 2) a 3) d 【原文】
Texas was the biggest state before Alaska became the forty-ninth state in 1959. One good way to understand the size of Texas is to learn about its weather. Different parts of the state have very different kinds of weather.
Laredo is one of the hottest cities in the United States in summer. The best time to visit Laredo is in winter, when it is pleasantly warm.
Amarillo gets very cold in winter. Sometimes there is more snow in Amarillo than in New York, which is a northern city. Summers are better, but sometimes it gets quite hot. The best time to visit Amarillo is in the autumn when it is cool.
If anyone asks you about the weather in Texas, ask him, “What part of Texas do you mean”
Task 2 【答案】 A.
1) T 2) F 3) F B.
1) d 2) c 3) c C.
climate, reputation, extraordinary, unreliable, dry, wet, clear, dull, hot, cold, bad, mild 【原文】
Our friend, Nick, whose English gets better and better, declared solemnly the other day that he thought that the British climate was wonderful, but the British
weather was terrible. He went on to explain by pointing out that the British climate was a temperate one. This meant, he said, \the weather would never be extreme — at any rate not for any length of time — never very hot and never very cold.\Britain, according to the statistics, was not very heavy. \then,\he asked, \the British climate such a bad reputation\the extraordinary, unreliable weather. There was no part of the year at which you could be certain that the weather would be dry or wet, clear or dull, hot or cold. A bad day in July could be as cold as a mild day in January. Indeed you could feel cold at almost any time of the year. Nick blamed drafty British houses for this, but agreed you could also blame the small amount of sunshine and a great amount of dampness. He advised every student coming to Britain to bring an umbrella and to understand the meaning of that splendid word \

【原文】
Cities change the climate around you. In the country, there are trees, grass, lakes, and streams. In hot weather, the trees and grass cool the area around them. Lakes and rivers also cool the area around them.
But cities are not cooled in these natural ways. Cities are built of asphalt, concrete, iron, and
steel. There are few trees and usually not much grass. Rain falls onto the streets and into the sewers.
When the summer sun shines, streets and buildings take in the heat; after the sun sets, the streets and buildings throw off heat into the street. Once the sun sets, the countryside cools off, but a city may stay hot all night.
Cities are hotter than the countryside in winter, too. Standing near a car with its motor running, winter or summer, you will feel the heat thrown off by the engine. The heat comes from the gasoline burned by the engine. This heat warms the air and the ground around the car. Thousands of running cars are almost like thousands of small fires burning.
Carefully put your hand near a light bulb or television set. As you can see, electricity creates a lot of heat. This heat from electricity warms the house and the outside air.
The heat given off by cities can affect the climate. Some experts even believe that cities can change the climate of the whole world. They think that air pollution may stop sunlight from reaching the earth. If less sunshine reaches the earth, the earth may become cooler.
Still other experts think the world will get warmer. If the world did get warmer, great changes would occur. Ice near the North and South poles would melt. This would make the oceans rise. Cities near oceans — like Los Angeles, Boston, and Miami — would slowly be flooded. People living in these cities would have to move to higher
land.
Task 4
【答案】 A.
1) b 2) c
B. night, delight; morning, warning; gray, way, red, head C.
1) F 2) T 3) F 【原文】
A red sky at either dusk or dawn is one of the spectacular and beautiful weather predictors we have in nature. By closely observing this phenomenon, you can achieve short-range accuracy of the weather as good as, or better than your local weatherman. In the Bible, Jesus in Matthew 16, 2-3 is quoted as saying, “When it is evening, it will be fair weather: for the sky is red. And in the morning it will be foul weather today: for the sky is red” when speaking to the Pharisees. An old English weather proverb based on this passage is:
Red sky at night, sailors delight. Red sky at morning, sailors take warning. Or
Evening red and morning gray, Sends the traveler on his way. Evening gray, morning red, Brings the rain down on his head.
At dusk, a red sky indicates that dry weather is on the way. This is due to the sun shining through dust particles being pushed ahead of a high pressure system bringing in dry air. A red sky in the morning is due to the sun again shining through dust. In this case however, the dust is being pushed on by an approaching low reassure
system bringing in moisture. Don't confuse a red sky in the morning with a red sun in the morning. If the sun itself is red and the sky is a normal color, the day will be fair.
Task 5
【答案】
1) c 2) b 3) d 4) c 5) c 【原文】
Mark: I am an avid fly fisherman and frequently find myself on the river
in a raft during lightning storms. We always have a debate at these times on where we are safest — pulling into shore or staying on the water. Since I have heard one is safe in a car when lightning strikes I wonder if the raft floating on the water is insulated, and therefore the safest place to be.
Meteorologist A: We spoke with some scientists about your question, and they all
agreed that under no circumstances should you remain on the water during a lightning storm. If your raft is made of rubber, you might feel that you're .well insulated, but don't kid yourself. Typical lightning flashes travel 10 to 15 kilometers and can deliver as much as 100,000 amps of current. In comparison, a toaster uses about 10 amps of current. If lightning strikes the water near you, it will have no trouble traveling through a few extra centimeters of rubber.
Meteorologist B: So, if you're on the water and a thunderstorm approaches, get to
the shore and seek shelter on land. Try a building or car. If neither is available, look for a cave, cliff, wall, or a group of trees. Never take shelter under an isolated tree-it's also a good target for lightning.
