【题目】There are a lot of reasons why people calling 911 might not be able to tell operators which floor they’re on in a high-rise building. They could be injured or simply confused. Yet precious minutes are wasted when emergency personnel have to search a building to find a person in need. With a new app called Sensory, emergency responders soon may be able to use a caller’s smartphone to locate his exact position in a building.

Columbia University researchers William Falcon and Henning Schulzrinne created Sensory using a two-step process. First, they used all existing smartphone features that help narrow down a caller’s location. All iPhones produced after 2014 already include GPS and altimeter(测高仪) that can help emergency responders determine if a person is outdoors or inside a building. But when it comes to tall buildings, just knowing a person’s altitude may not be enough,because the i distance between floors changes from one building to another.

So Falcon and Schulzrinne analysed the plans of figuring out the average distance between floors in residential(住宅的)buildings and office buildings among more than 1000 buildings in New York City. They tested their app in 63 experiments in five high-rise buildings and found that it could find a caller’s location within two floors with about a 91 percent accuracy.

In a survey conducted by Find Me 911 this year, dispatchers(调度员)said that they regularly received calls from people in need who often couldn’t share their location. They sometimes accidentally give the wrong address or floor number. Some callers are too young to know their address. Dispatchers also received calls from those who are deaf or have hearing problems and they often couldn’t hear the operator’s questions.

The new Sensory app could help shave precious minutes off the time it takes first responders to get to those calling for help. And it could make the difference between life and death.

2What can the Sensory’s first step help emergency responders do?

A. The reasons for failing to get exact location.

B. The basic information about emergencies.

C. The potential danger of failing to rescue.

D. The different kinds of emergency callers.

4What is the author’s attitude to the new app?

【题目】阅读下面短文,然后按照要求写一篇150词左右的英语短文。

An old proverb says, "Overcome evil by doing good." I read the news and see people who behead(将……斩首)others in the Middle East, abuse maids and domestic workers in Hong Kong, steal money and misuse power in government (not only in China but in the U.S. and every other part of the world), those who claim certain social ideals while privately practicing greed and living lifestyles that totally contradict their so-called 'ideals.' I only see the headlines and rarely read the stories. It is too depressing.

So, what do you do when there is so much evil in the world? What can YOU do about it?

There's only one thing that I know to do. I know (and feel it deep in my heart) to do good.

My way of overcoming evil in the world is too invest in the lives of Chinese children. I do this every day. I love 'giving back'. I love taking the money I earn and investing back into the lives of children. I will create a language learning lab in a public high school's international department (I already bought four new computers for it this week). The students need the tools to work on their English exams and prepare for TOEFL, IELTS and the SAT. There's no provision for them to have such a resource right now, so, rather than complain about it not being done, I decided, 'why don't I do something about it.' I know that I can and just decided to do it. It isn't anything great, but it will make a difference in the lives of some.
