题目内容

A sick little girl is being kept alive thanks to her best friend — a dog who carries her oxygen tank on his back. Alida’s faithful dog companion Mr Gibbs has been specially trained to shepherd the three-year-old, who breathes through a tube most of the time. He follows her closely as she plays in her family’s ten-acre land in Louisville, uses the slide or even rides her bike.

Alida was diagnosed with neuroendocrine hyperplasia of infancy（NEHI）when she was just eight months old. Her rare condition has just eight hundred documented sufferers throughout the world, and causes diseased pieces of the lungs to filter oxygen through extra layers of cells, making it hard or almost impossible to breathe. For Alida and her parents, it meant that even a walk in the park was very difficult because oxygen equipment was too heavy for the youngster to be able to carry herself. As parents, they wanted to do something to help their daughter survive despite having a tube following her all the time. The couple found out about “service dogs” from a TV program and realized an animal trained to help the blind could be trained to help Alida. They finally found help in the shape of golden doodle—a retriever crossed with a poodle-dog Mr Gibbs. Now thanks to trainer Ashleigh Kinsley—Alida and Mr Gibbs love nothing more than playing and running around together with the dog acting as Alida’s life saver.

1.What is Mr Gibbs?

A. A pet dog. B. A policeman.

C. A doctor. D. A firefighter.

2. When did the doctor know Alida caught the disease?

A. At her birth.

B. At the age of eight.

C. Before she was one year old.

D. When she was three years old.

3. The underlined part “the couple” in paragraph 3 refers to _______.

A. Alida’s classmates B. Alida’s parents

C. Alida’s doctors D. Alida’s pets

4.How did Alida keep alive?

A. By training her dog.

B. By staying with her parents.

C. By playing with her fellows.

D. By breathing through a tube.

Dogs are known for a strong sense of smell. Their noses can be trained to identify different smells. Dogs are often used in search and rescue operations and to sniff for things like drugs and explosives. Some dogs have even been trained to sniff for cancer in people.

Researchers have been trying to reproduce the extraordinary sense of smell that real dogs are born with. Now, officials at the Glasgow airport in Scotland are testing a new security device called an “electronic sniffer dog”. The electronic sniffer dog represents one of the latest developments in the area of smell technology.

A Scottish company, Cascade Technologies, joined with the French security company Morpho to develop it. The device uses lasers to identify explosive materials in gases in the air. The purpose is to identify explosives that may be hidden on a person’s body.

The machine looks similar to the metal detectors now used at airports. Passengers walk through the machine as the lasers test the surrounding air. People are not required to take off their coats, belts or shoes as part of the security process. And, unlike full-body scanners, the new device does not show images of the passengers.

Officials at Cascade Technologies say the machine can process one person per second and produce almost immediate results. They say future development could cut security processing times at airports by screening all passengers at walking speed.

Professor Yushan Yan, the head of Chemical and Environmental Engineering at the University of California, Riverside, points out that unlike real dogs, electronic devices do not get tired or need to be walked or require food and water. Professor Yan says real dogs also have other needs. “They also need very extensive training that could be expensive. And when they work they have to have a very skilled handler around them.”

But Professor Yan says there is an important area where man’s best friend still wins compared to technology. “In terms of sensitivity and selectivity, the current technology out there is still inferior. The real dog has amazing capability of identifying some really minor amount of explosives.”

1. The electronic sniffer dogs will be used to____

A. replace real dogs to be as pets for people

B. search for and rescue people who are in trouble

C. help people look after patients in the hospital

D. identify drugs and explosives in places like the airport

2.Which of the following is true of the electronic sniffer dog?

A. The device uses lasers to examine for explosive materials.

B. People have to take off their clothes when walking through the device.

C. The device will show images of the passengers.

D. The device can process all passengers at walking speed.

3. The advantages of the electronic sniffer dog over the real dog include the following EXCEPT______

A. its convenience B. its high efficiency

C. its sensitivity D. its low consumption

4.The underlined word “inferior” in the last paragraph most probably has the meaning of_____.

A. concentrating all one’s effort on a specific area

B. not as good as sb. / sth. else

C. that cannot be clearly understood

D. necessary for completeness

2014 saw that the Ebola virus reappeared in Guinea and soon spread into neighbouring Liberia and Sierra Leone, killing over 7,800 people by the new year of 2015. It leads to viral hemorrhagic fever, which is characterized by high fever and internal bleeding etc.

Ebola is named after the Ebola River, where it was first discovered in 1976. There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Reston, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 out- break, and is believed to be attacking Guinea.

Ebola is naturally found in fruit bats, which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids of the infected animals. Once infected, a human becomes a carrier of the deadly virus.

Unfortunately, there are no disease - specific treatments for Ebola. Health - care workers only supply the infected people with physiological saline（生理盐水）to keep them in good condition. Ebola can kill 90% of those infected, especially in underdeveloped societies like those in Africa. Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the infected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.

What’s worse, since we live in an interconnected world, where the situation in one country can affect us all, the influences of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries. It is feared that the disease may spread throughout west African countries. For every country, a strong health system can decrease the risk of health attack and lessen the impact of Ebola.

1.What is the function of the first paragraph in the whole passage?

A. To arouse the reader’s concern.

B. To summarize the whole passage.

C. To give a detailed description of Ebola.

D. To introduce the theme of the whole passage.

2.What can we infer about the Ebola virus?

A. It has caused a panic in many countries.

B. It is the most dangerous virus in the world.

C. A strong health system is important to fight against Ebola.

D. Anyone who was infected Ebola will die.

3.Paragraph 3 mainly tells us _________.

A. What the Ebola virus is

B. How the Ebola virus spreads

C. How the Ebola virus is treated

D. How the Ebola virus affects the life

4.Which of the following is true?

A. There are no effective drugs to treat Ebola by far.

B. Ebola is now very common in Guinea.

C. Those with a fever must be infected by Ebola.

D. Females are easier to be infected by Ebola.

Elizabeth Freeman was born about 1742 to African American parents who were slaves. At the age of six months she was acquired, along with her sister, by John Ashley, a wealthy Massachusetts slaveholders. She became known as Mumbet or Mum Bett.

For nearly 30 years Mumbet served the Ashley family. One day, Ashleys wife tried to strike Mumbets sister with a spade. Mumbet protected her sister and took the blow instead. Furious(狂怒的), she left the house and refused to come back. When the Ashleys tried to make her return, Mumbet consulted a lawyer, Theodore Sedgewick. With his help, Mumbet sued(起诉) for her freedom.

While serving the Ashleys, Mumbet had listened to many discussions of the new Massachusetts constitution. If the constitution said that all people were free and equal, then she thought it should apply to her. Eventually, Mumbet won her freedom---- the first slave in Massachusetts to do so under the new constitution.

Strangely enough, after the trial, the Ashleys asked Mumbet to come back and work for them as a paid employee. She declined and instead went to work for Segdewick. Mumbet died in 1829, but her legacy lived on in her many descendants(后裔). One of her great-grandchildren was W.E.B. Du Bois, one of the founder of the NAACP, and an important writer and spokesperson for African American civil rights.

Mumbets tombstone still stands in the Massachusetts cemetery where she was buried. It reads, in part: She was born a slave and remained a slave and remained a slave for nearly thirty years. She could neither read nor write, yet in her own sphere she had no superior or equal.
