2019版高考英语外研版一轮复习习题练习：必修4 Module 2《Traffic Jam》(含解析)

第一部分 必修四 Module 2

Ⅰ.阅读理解

(2019·吉林二模)

In Los Angeles, drivers spend sixty-one hours every year stuck in traffic. These drivers know

too well how bad the traffic can be. “There're too many cars, and you can't move around a lot.”

Professor Cyrus Shahabi also knows about traffic jams. He lives more than 65 kilometers from

his office at the University of Southern California in Los Angeles. He is always late even with the

help of a navigation (导航) system.

He decided to develop a program called ClearPath for that. He says his program uses historical

data to predict traffic conditions even before the driver leaves the house.

“What's unique is that we use a lot of data that's currently become available including traffic

data, weather data, and we analyze that so that we can predict what's going to happen in front of you

when you leave home.”

Professor Shahabi says his system does more than just respond to current traffic conditions.

With ClearPath, he says, a driver can decide what time he wants to leave, and ClearPath will give the

fastest route. It looks at the entire road network, including surface streets as well as highways, before

the driver hits the road. Professor Shahahi hopes to have ClearPath available nationwide and

overseas once they can collect traffic data from other cities.

“I always thought that Los Angeles had the worst traffic, but now I know that Shanghai,

Beijing, Seoul, Tokyo, believe it or not, Singapore, Hong Kong certainly are examples that can

immediately use this.”

Professor Shahabi hopes to share this new technology with companies that already have

navigation systems, such as Google and Apple.

Doctors Say Most Heart Disease Preventable

Heart disease is the number one killer, worldwide, of men and women over the age of 60. But

people of all ages die of heart attacks each year. And while death rates have declined in the U．S. and

many western European countries, they are on the rise in the developing world. __1__.

No one would have guessed that Barbara Teng would have a heart attack. She was not

overweight. She did not smoke or exercise. “In 2004，the week after I turned 49 ，when I was on a

business trip in Chicago，I had a major heart attack，”she said.__2__. She now exercises daily, and

monitors her heart health.

Dr. Patrice Nickens, who is with the National Heart, Lung and Blood Institute, thinks that

heart disease is 82 percent preventable. “__3__，” she said.“Men are also facing the same problem,

and the key to staying healthy is knowing your numbers.”

“Your weight, your blood cholesterol, blood sugar and your blood pressure are important

numbers that can help you take action and reduce your risk，” she said.

__4__. “And the steps to take are simple：don't smoke, maintain a healthy weight, exercise, know

your numbers and talk to your physician and control these risks，” she said.

African-Americans are at higher-than-average risk for heart disease and stroke；people don't

even know they have it, which increases the risk. Medstar Washington Hospital Center is trying to

reach this population.__5__. For example, helping the people monitor their blood pressure. If people

realize they are at risk for heart disease, they'll make lifestyle changes： lose weight, exercise, eat the
