4 . Weather reports often mention high or low pressure systems headed toward a city or town. If you’re in the path of one of these systems, expect a change in weather conditions. High and low pressure systems operate using similar principles, but the effects they produce differ significantly.

View a weather map, and you may see distinct regions that represent different air masses. An air mass is a region of air that has about the same humidity(湿度) and temperature throughout. When an air mass remains over a location for a while, it decides the characteristics of the region. Air masses can be cold or warm and they may contain wet or dry air. All air masses have the ability to move away from their source region into other locations.

Meteorologists(气象学家) call the boundary between two air masses a front. A cold front’s motion through a warm front is a low-pressure system. If a cold air mass replaces a warm air mass, you have a cold front. Air in the cold air mass is often drier than air in front of it. As the air masses meet, the wind usually changes direction and rain or thunderstorms often occur.

A warm front is associated with a high-pressure system and occurs when a warm air mass replaces a colder air mass. A high-pressure system often brings clear, calm weather. Warm fronts travel slowly and are weaker than cold fronts.

Cold fronts move faster than warm fronts because a cold front contains denser air. Cold fronts also often travel from west to east while warm fronts move from north to south. As a warm front approaches, temperatures may rise as warmer air flows in from a warm air mass. However, when the cold front hits, temperatures can drop precipitously within a short time.

1. How is the temperature of a region under a certain air mass?

A．Unusual.

B．Stable.

C．Diverse.

D．Changeable.

2. What happens when two air masses meet?

A．A clear sky appears.	B．A strong wind is formed.
C．The air becomes wetter.	D．The wind changes directions.

3. What does the underlined word “precipitously” in the last paragraph mean?

A．Sharply.

B．Slowly.

C．Possibly.

D．Specially.

4. What is mainly talked about in this text?

A．The formation of air masses.	B．The new findings of meteorologists.
C．The effects of air mass and fronts on weather.	D．The methods for accurate weather forecasts.

5 . A study published on May 24 offers an explanation for a mysterious (神秘的) and sometimes deadly weather pattern in which the jet stream (急流), the global air currents that circle the Earth, wanders over a region. “Much like highways. The jet stream has a limit,” researchers said, “and when it was beyond its limit, blockages (拥堵)form that are remarkably similar to traffic jams—and climate forecasters can use the same math to model them both.”

The deadly 2003 European heat wave, California’s 2014 drought and the swing of Superstorm Sandy in 2012 that surprised forecasters—all of these were caused by a weather phenomenon known as “blocking”, in which the jet stream wanders, stopping weather systems from moving eastward. Scientists have known about it for decades, almost as long as they’ve known about the jet stream—first discovered by pioneering University of Chicago meteorologist (气象学家)Carl-Gustaf Rossby, in fact—but no one had a good explanation for why it happens.

“Blocking is very difficult to forecast, in large part because there was no clear theory about when it forms and why,” said study coauthor Noboru Nakamura, a professor in the Department of the Geophysical Sciences.

Nakamura and then-graduate student Clare S. Y. Huang were studying the jet stream, trying to determine a clear set of measurements for blocking in order to better analyze the phenomenon. One of their new metrics (度量)was a term that measured the routine of the jet stream. Looking over the math. Nakamura realized that the result was nearly the same to one designed decades ago by transportation engineers trying to describe traffic jams.

Much like car traffic, movement slows when multiple highways come together and the speed of the jet stream is reduced due to mountains or coasts.

1. What is the similarity between jet stream and traffic jams?

A．Both of them are mysterious.

B．Both of them can be predicted.

C．Blockages can be solved in the same way.

D．Blockages form when they are beyond a certain limit.

2. What can be inferred from the passage?

A．Nakamura helped explain the blocking phenomenon of jet stream.

B．Carl-Gustaf Rossby discovered the cause of the jet stream.

C．Scientists have known the swing of Superstorm Sandy in 2012 before it happened.

D．Blocking phenomenon of jet stream happened when multiple highways come together.

3. What is the best title for the passage?

A．Some Great Scientists in a Study

B．A New Explanation for Traffic Jam

C．Some New Discoveries for Traffic Jam

D．A New Theory Finds “Traffic Jams” in Jet Stream

4. Where does this passage probably come from?

A．A science magazine.	B．A guidebook.

9 . 语法填空

Shuang Jiang or The Frost’s Descent is the     1    (eighteen) of 24 solar terms in the Chinese lunar calendar. It is the last solar term of autumn,     2     the weather becomes much colder     3     before and frost begins to appear ,and marks the transition from autumn to winter. It means that the winter is about     4    (enter). The Frost’s Descent usually     5    (fall) on October 23 or 24, but this year it begins on October 23. The solar term, ”Shaung Jiang”, reflects the large change in temperature between day and night and at     6    same time the weather is getting colder. The moisture in the air is also beginning to turn to frost. The autumn harvest is also coming to a close, and the year’s worth of hard work     7    (final) sees reward.

As Frost’s Descent comes, the world     8    (fill) with the atmosphere of late autumn. At this time, most of the harvesting work is already completed in northern China and     9    (farmer) are finally able to rest. Even the most cold-resistant crops can no longer grow, thus it is time to stock up for winter. Although in the south, the harvest is still continuing. As     10    (record) in ancient Chinese books, the Frost’s Descent refers to the time of year when frost starts to creep across China, dew becoming icy thanks to plummeting temperatures.
