Weather has a great influence(影响) on people.It influences people's health, intelligence (智力) and feelings.

In August, it is very hot and wet in the southern part of the United States.People there have heart disease and other kinds of health problems during this month. In the Northeast and Middle West, it is very hot at some times and very cold at other times.People in these places may have heart disease after the weather changes in February or March.

The weather can also influence intelligence. For example, in a 1982 study by scientists, the in scores of a group of students were very high during a storm, but after the storm their IQ scores were lower than usual level. So storms can increase intelligence.However, very hot weather can lower it. Students in the United States often do badly on exams in the hot months of the year.

Weather also has a strong influence on people's feelings.Winter may be a bad time for thin people.They usually feel cold during these months and they may feel unhappy during cold weather. In hot summer weather, on the other hand, fat people may feel unhappy. The sum- mer heat may make them tired and they are easy to get angry.

第3题:

Popular breakfast foods in the United States, as in many other countries around the world, include coffee, milk, juice, eggs and bread. Some other breakfast items served in the United States are thought by many to be traditionally American. However, they actually come from other countries.

A very popular breakfast food in America is the pancake---a thin, flat cake made out of flour and often served with maple syrup. The idea of the pancake is very old. In fact, pancakes were made long ago in ancient China.

Bagels, a round thick bread with a hole in the middle, are also popular for breakfast in America. Polish people in the late 1600s came up with the idea for the first bagels and this new kind of bread soon took off across Eastern Europe.

In the late 1800s, thousands of Jews from Eastern Europe traveled to the United States and brought the recipe for bagels with them. Today, New York bagels are said to be the best in the world. Many people have them with cream cheese for breakfast on the go.

Doughnuts (usually spelled “donut” in the United States) came from France. They were served to American soldiers in France during World War Ⅰ(第一次世界大战). After the war, American soldiers asked cooks in the United States to make doughnuts for them. Now, served with coffee, they are a very popular breakfast food across the United States.

A. famous places in the United States to eat breakfast

第7题:

There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.

Another way is energy conservation ( 节能 ), which means using energy more efficiently ( 有效地 ). In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of the people and the other equipment in it.

Finally, renewable energy sources are used even though they are often expensive to develop. One form. of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped ( 压;抽 ) down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.

1、How many ways of dealing with the energy problem are discussed in the text? ( )

A、Two.

B、Three.

C、Four.

D、Five.

2、From the text we learn that coal( ).

A、is quite easy to produce

B、is not used most efficiently

C、is the most common source of energy

A、show the excellent skills of the builders

B、serve as an example of energy conservation

C、are heated by different sources of energy

D、are warmer than other types of houses

4、The underlined words "geothermal energy" in the third paragraph mean ( ).

A、renewable source

B、 underground source

C、 heat inside the earth

D、 temperature of the earth

5、At a place where the surface temperature is 15°C, how deep do you have to dig so as to get a temperature of 75 °C ? ( )

A、One km.
