Passage 1
A kiln(窑) is a type of oven or furnace used to cure，harden，or burn certain materials.
Depending on which materials are heated in it，a kiln may be square，tunnel-shaped，or beehive-shaped，and usually made of brick or stone._________(71) It may be set as low as sixty-five degrees to cure grain or as high as 3,200 degrees to transform limestone(右灰石) to quicklime(熟石灰).
____________(72)They have a variety of purposes.The cement(水泥) industry uses revolving kilns to hat and separate raw materials,Bricks，pottery，and china made from clay must be fired or hardened in kilns.Certain kinds of coal and wood must be kiln-dried before they can be used.Hobbyists use small kilns to fire a variety of ceramic(陶瓷) objects.
There are two main types of kilns. A periodic kiln,used to fire certain kinds of delicate china,is raised to a high temperature and then completely cooled before its contents are removed. A continuous,or tunnel kiln contains several chambers, or zones, which heat, bake,and cool a product.Stacks of clay bricks move through a tunnel kiln on tracks.________(73)
Gas,oil,and coal are all used to heat modern kilns.________(74)But for special jobs,where cleanliness and careful heat are important, kilns must be heated by electricity oven though it is more expensive.|Small kilns used in the home or in craft shops are also heated electrically because electricity is clean and convenient.
___________(75) When ancient people discovered that heat hardened some materials，they were able to make durable household objects such as jugs and bowls.Today our museums display many kinds of ancient statues and art objects that have lasted because they had been kiln-dried. They come from lands as far apart as China and Greece.
A. lts temperature may vary.
B. Then they come out, hardened, and cooled.
C. Kilns are used in industry and in craft-making.
D. Kilns have been in use for thousands of years.
E. An electric kiln is a heating chamber used to transform materials.
F. Most manufacturers use whichever material is cheapest in their area.e
G. Clay, when heated properly, becomes hard enough to form bowls and plates.

Passage 2
Radar is an electronic device that detects planes, ships,coastlines, landmarks, and even storm clouds.The name radar comes from the first letters of the words radio direction and ranging.As the human eye uses light waves to see,radar “sees" with radio waves. Without radar,planes could not land safely in bad weather and ships could not move safely in thick fog.____________.(51)
In the 1800s it was discovered that radio waves could be reflected from objects. But scientists did not make great advances in radar research until the 1930s,when the world was threatened by war._________(52) It has been used widely in almost every conflict since then.
Echoes make it possible for radar to work. When abeam of radio waves is sent out, it strikes on an object and returns an echo. This echo is picked up by radar and recorded on a screen similar to television screen.On the screen an observer sees a flash, or a blip, that shows the direction and distance of the object._________________.(53)
Airport control towers use radar to guide planes in for safe landings.Almost all large
ships depend on radar to prevent collisions with icebergs or other ships._____________(54) Weather forecasters“see" the size,direction,and speed of storms on radar screens.
Astronomers can even use radar to measure accurately the distance to the moon.Thus, the device has generated major advancements.
____________(55) Huge radar antennas have been installed all over the United States.They guard us against possible enemy attacks. We have ballistic-missiles (战略导弹) warning systems that can alert us to attacks when missiles are more than 1,000 miles away.Other radar systems warn us against enemy aircraft and even spying space satellites.
A.Police track speeders in radar-equipped cars.
B.These measurements are now highly accurate,
C. The device can be used in a wide range of fields.
D. lt is therefore especially valuable to shippers and travelers.
E. During World War ll many countries used radar effectively.
F. Today radar is used by commercial airliners and weather forecasters.e'
G. Strengthening national defense is one of radar's most important functions.

Passage 1
Sleep and Teens - Biology and Behavior
How much sleep do teens need And how much sleep are they realistically getting Based on current data, most teens need about 9-plus hours to have the best or most suitable sleep at night.________.(51)
Many factors combine to decrease sleep in adolescents.we can think in general of two major factors: biological,the brain processes that regulate the amount and timing of sleep,and behavior，all the psychological，parental,societal, cultural features of a teen's life.
__________(52) These changes lay the ground work for the biological night to occur later during the teen years than before.Circadian Rhythms (daily biological clock) seems to slow down as young people progress through the middle school years.At the same time, the sleep pressure system appears to change in a way that makes it easier to stay awake longer，though without changing the amount of sleep that is needed.
Moreover, many teens have a“technological playground" in their bedrooms: television,computer with24/7 Internet access,telephones，electronic game stations,MP3 players, and so forth. These technologies provide instant and constant contact with peers.Societal and media pressure to consume these technologies is now higher than ever.Yet society also requires that teens go to school at a time of day that is at odds with their biological and social lives. So we see teens turn to caffeine, late-night Internet and cramming in activity after activity as a means to keep awake.__________(53)
Problems emerge for lack of sleep._________.(54)For some, grades begin to suffer as they struggle to keep awake during class and while doing homework. And others may simply feel moody, never knowing how to feel or do their best.Worse still, many teens suffer from both physical and mental illness.
_____________(55) The earlier teens can start this good sleep habit,the easier it will be for them to stay healthy, happy and smart.

(72)They keep in touch with their host families after they return home,and many return to visit.

while others simply want to take time out from a job and do something else.________(73)
However,many voluntourists do not see volunteering as what it is.They think it is a cheap way of traveling and don't really want to get involved in hard work.
While voluntourism has been around for over a century,modern volunteering started with the Peace Corps,a program that the Us government started in the 1960s.From then on, voluntourism has become more and more popular.
