For thousands of years, people have used plants to make medicines. They used different parts of the plants —the roots, the leaves, the flowers, and the bark (树皮). Today, doctors have rediscovered more medicinal (药用) values of some plants. Let’s look at some examples.
Foxglove is a common plant. People have used it to make the heart slow down. Recently scientists have developed another drug from it. This new drug helps prevent other heart problems.
In some areas, malaria has been a problem. Scientists have learned that the bark of a South American tree, the cinchona, can be made into a drug to prevent malaria. For a long time, the Chinese have known that a special plant, wormwood, can also fight malaria. Scientists have been working with it to develop new drugs against malaria.
In Germany, some scientists studied garlic (大蒜) for four years. They found that it helps prevent the build-up of plaque (血小板) because too much plaque is bad for health. This very common plant continues to be studied.
As we know, there are about 250,000 kinds of flowering plants in the world. Scientists have only studied little more than one percent of plants for their medicinal value. Maybe medicines for AIDS and cancer will be made from the other 99 percent.
1.What can foxglove be used for?
A.Studying plants.
B.Building up the plaque.
C.Treating AIDS and cancer.
D.Preventing heart problems.
2.What does the underlined word “malaria” in Paragraph 3 refer to (指的是)?
A.A drug. B.A plant.
C.An illness. D.An animal.
3.How many plants are mentioned in the passage?
A.3. B.4. C.5. D.6
4.Which of the following is the best title for the passage?
A.Past and future
B.Plants and medicine
C.Health and illness
D.Scientists and doctors

People have used pigeons to carry messages to one another for hundreds of years. In the 12th century, the royal palaces of Iraq and Syria included pigeon houses so the kings could be kept informed of their generals’ victories and defeats on the battlefield. In fact, pigeons were a common way to send messages right up through World War II.
Many countries, such as the United States, England, France, Germany, and Italy, in both World War I and World War II, used carrier pigeons. Not only were the birds often the fastest, most reliable way to send messages, they could also be used to reach soldiers far behind enemy lines, where radios and field telephone lines were useless. Since they could easily be released (释放) from airplanes or ships, every branch of the armed services used the birds. In World War II, more than 3,000 soldiers and 150 officers were needed to care for and train the tens of thousands of birds in the U.S. Pigeon Service.
Carrying messages could be a dangerous job. Some pigeons performed with such bravery that they became famous and were even awarded medals, such as England’s Dicken Medal of Gallantry. In a few cases, pigeons even became prisoners of war. In 1918 American forces captured a pigeon named Kaiser, which had been trained to fly special missions for Germany during battle. He was taken to America, where he lived to the age of 32. The most famous pigeon of all may have been Cher Ami. Stationed in France during World War I, he carried twelve important messages for American forces. On his last mission, though wounded, he carried a message that saved the lives of 194 American soldiers. For his extraordinary service, he was awarded the French “Croix de Guerre.”
Carrier pigeons are a slightly different breed (品种) from the kind of pigeons you see on city streets. They are much thinner and taller, with longer legs. Many people find carrier pigeons ugly because of their big wattle, a bent buildup of skin on the beak(鸟嘴); however, people who raise pigeons often enjoy this strange appearance and consider carriers the best of their breed.
Today, modern communication methods can carry information from one place to another hundreds of times faster than a pigeon could do. However, few people would argue with the fact that carrier pigeons—especially those that served in the military—have earned their place in history. Stories about brave pigeons such as Cher Ami, President Wilson, and Colonel’s Lady have the power to inspire us as no fax machine or high-speed Internet connection could ever do.
1.Many countries used carrier pigeons in the war because_______.
A.they could be believed in
B.they were easily raised
C.they could reach the enemy lines
D.they could hardly be found by airplanes
2.Which is the best example to show the bravery of carrier pigeons?
A.Carrier pigeons could fly to places where radios and telephone lines were useless.
B.For his extraordinary service, Cher Ami was awarded the French “Croix de Guerre”.
C.In World War II, more than 3,000 soldiers were needed to care for and train the pigeons.
D.In the 12th century, kings in Iraq were kept informed of the victories and defeats by pigeons.
3.From the passage, we can learn _________.
A.how carrier pigeons developed in history
B.how to train carrier pigeons to get victory
C.carrier pigeons played an important role in the wars in the old days
D.pigeons inspired soldiers to fight before high-speed Internet invented

For thousands of years, people have lived with dogs. Ancient paintings on the walls of caves show people living with dogs. Almost a third of the homes in the United States and England have dogs, and these dogs come in a wide variety of shapes and sizes.
The largest dog in the world was a dog named Zorba. When Zorba, a mastiff, was seven years old in 1989, he was 94 centimeters (37 inches) tall. In other words, Zorba was more than half as tall as an adult man. At his largest, Zorba weighed more than a heavy weight boxer at 156 kilograms(343 pounds).
In comparison, the smallest bog was a Yorkshire terrier from England. This dog was only the size of a matchbox, measuring 7.1 centimeters(2.8 inches) tall and 9.5 centimeters (3.75 inches) from nose to tail. It weighed about half as much as a common book, and even a young child could easily pick it up with one hand. It passed away in 1945 when it was only two years old.
Some dogs are wonderful, not for their sizes, but for their brains. One incredible (难以制信的)dog is Endal, the companion (陪伴) of a man named Allen Parton who has used a wheelchair since a car accident in 1991.
In 2001, Parton was hit by a car while crossing a road with Endal, and thrown out of his chair. Endal quickly moved Parton into the recovery place, covered him with a blanket(毯子), and pushed his mobile phone close enough for him to reach. Then, once he saw that Parton was all right, Endal ran back and forth to a nearby hotel, barking until people came out to help.
Endal was rewarded for his bravery by being awarded a medal, and he has been the subject of a number of TV documentaries.

For thousands of years, dogs have held a special place in people’s hearts. They are known as “ man’s best friend” . This is because they can be so brave, lovely, and loyal(忠诚). Dogs are used to living in groups and following the leader. Now humans are their leaders. Dogs depend on people for food— mostly meat— and perform services in return.
Long long ago, dogs worked for people. They ran after wild animals, caught them on land and water, and protected houses. They are used to send messages, look after sheep, and even save people in snow. They help police find out what they want. Fast-runningdogs are used in races.
Dogs have many abilities that make them useful. Sharp teeth are only one of these. Most dogs can smell something human can’t smell and hear higher notes than any person. And although dogs don’t see many colors, they are very good at noticing movements.
Dogs come in many shapes, sizes, and characters. A big Irish dog stands about 32 inches tall. However,some dogs stand about only 5 inches tall. Dogs that can guard homes are intelligent. Police dogs are usually quite brave. But many different kinds of dogs now make playful family pets.
Dogs have been kept to work for human for a long history. When Pompeii— the ancient Italian city that was buried about 1900 years ago— was dug out, a dog was found lying across a child. It was trying to protect the child.
