【題目】Medical education and engineering education belong to totally different categories and are always on ________ tracks, it is difficult to develop cross-subjects between them.

A. suitable B. relevant C. parallel D. abstract

【答案】C

【解析】

考察形容詞詞義辨析。句意：醫(yī)學(xué)和土木工程屬于兩個(gè)截然不同種類的學(xué)科，沒有任何的交集，因此很難在這兩個(gè)學(xué)科上建立交叉學(xué)科。A. suitable合適的；B. relevant 相關(guān)的；C. parallel 平行的；D. abstract抽象的。根據(jù)前文totally different categories可知，兩個(gè)學(xué)科沒有交集，故on parallel tracks在平行軌道上，故C切題。cross-subjects交叉學(xué)科。

【題目】 Eric Davis got interested in firefighting when he was in the army. And while much of his job today is related to EMS(emergency medical services)，his first love is fighting fires. "I enjoy the job and working with people. I enjoy firefighting.” he says.

Davis studied in a firefighting school for about three months and took part in classroom work，physical exercise，and hands-on training such as fighting live fires in buildings filled with straw.

Davis says the blindfold(蒙眼的)training prepared him for real fires. "By the time we get to a fire，if it’s going pretty good，the whole house will be filled with smoke. And anytime you get near the fire, you won’t be able to see at all. Zero visibility(能見性)is the same as darkness. The blindfold training works.”

Davis believes his most important duty is making sure he’s prepared for any situation he might come across. To keep physically fit，he runs several times a week and works out. He takes classes to keep up his skills and trains regularly by fighting practice fires. Sometimes this includes cutting holes in roofs, which helps allow smoke to pass out and improves visibility for firefighters inside the building.

Firefighting means plenty of risks. Besides，Davis says·"You have to be willing to help any person you come across.” If someone is trapped，Davis or another firefighter will put himself at risk to get the person out. Davis says he is not afraid when he’s fighting a fire. He does what’s needed.

【1】What is David’s main duty at present?

A.Providing emergency medical care.B.Fighting fires in tall buildings.

C.Giving firefighters training.D.Saving people trapped in fires.

【2】Where did David learn firefighting?

A.In the army.B.In the hospital.}

C.In the classroom.D.In a professional school.

【3】Why were learners trained blindfold?

A.To experience how the blind feel.B.To protect their eyes from the smoke.

C.To recreate a real fire situation.D.To prepare for firefighting at night.

【4】What can we infer about Davis?

A.He was once an army man.

B.He tries his best to be a good firefighter.

C.He helps improve the working conditions.

D.He is worried about the safety of firefighters.

【題目】 Yousuf and his family left their home in eastern Afghanistan eight years ago. They went to the city of Kabul to escape war, but they could not escape sadness. Five of Yousuf's children died in the Afghan capital, not from violence, but from air pollution.

Kabul has become one of the most polluted cities in the world. On many days, a mix of smog and smoke lies over the city. In some cases, families burn whatever they can to keep warm in cold weather. The air in their own homes then poisons them. Many years of war have worsened the damage to Afghanistan's environment. At the local Children's Hospital, doctors say they have seen the number of patients with pollution-related health problems increase. Saifullah Abassin, a doctor at the hospital, says his hospital ward(病房) can hold 10 patients but often has three times that number.

“Thirty years ago, it was a wish for people to come to Kabul and breathe its air,” said Ezatullah Sediqi, deputy director for the National Environmental Protection Agency. “But in the wars since, we lost all our urban infrastructure(基礎(chǔ)設(shè)施) for water, electricity, public transportation, green areas, all these things.”

Kabul's environmental department has started a program to control old vehicles, one major source of pollution. City officials have called on people to use fuel instead of burning garbage for heat. But there are other steps officials need to take, such as passing a plan to stop unplanned development and creating more green spaces.

【1】What made Yousuf and his family leave their home?

A.War.B.Sadness.C.Violence.D.Air pollution.

【2】What is NOT the cause of Afghanistan's environment problem?

A.Burning garage.B.Creating green spaces.

C.Using old vehicles.D.Losing urban infrastructure.

【3】In which part of the newspaper may this text appear?

A.Education.B.Environment.C.Science.D.Culture.
