Every day it seems that people are coming up with new and innovative ways to use mobile devices like cellphones and smart phones. Researchers at Princeton University are looking for new ways to measure a person’s sense of wellbeing with mobile devices.

To gain a better understanding of how cellphones and other mobile devices can measure our sense of happiness, the research team conducted a study that was published recently in the journal Demography. To gather data for their study, the team created an application for mobile devices using the Android operating system.

Once the app was developed, the researchers invited people to download it and take part in their study. Over a three-week period, the research team was able to collect data from some 270 participants living in 13 countries.

Participants came not only from the United States, but also from other nations like Australia, Canada, China, France, Germany, Israel, Japan, Norway, South Korea, Spain, Sweden and the United Kingdom.

Over the course of the study, participants received occasional text questions from the researchers that asked “How happy are you?”. Along with recording their response, the app used the mobile device’s built-in GPS to keep track of the participant’s location.

The study participants were asked to rate their current state of happiness on a scale of zero to five. As they gathered data from the information collected through the application, the researchers then were able to create new methods that could help provide a better understanding of how our surroundings can influence our emotional well-being.

The researchers learned that mobile devices can provide an effective way to quickly grab information that, because of today’s active lifestyle, can be difficult to record. Being able to quickly grab this information was something the researchers felt was important. They said feelings and emotions that were recorded as they were happening were most likely to be more honest and precise than using other methods like writing down how they felt on a piece of paper after the fact.

1.Which of the following statements is true according to the passage?

A. The study the team conducted has not been published yet.

B. About 270 people from 13 countries participated in the study.

C. The participants didn’t need to download the app to participate.

D. None of the participants came from the United Kingdom.

2.What did the researchers find vital as to rate people’s sense of happiness from the passage?

A. Recording people’s feelings and emotions quickly.

B. Writing down how they felt on a piece of paper.

C. Answering the text question “How happy are you?”

D. Knowing how the surroundings affect people’s happiness.

3.The underlined word in the first paragraph probably refers to ______.

A. emotion B. wealth

C. happiness D. technology

4.The best title of the passage is most likely to be “_______”.

A. People’s Sense of Happiness Related to Mobile Phones

B. Scientists Track Happiness with Cellphones

Compared to the other parts of the body, our ears don’t ask for much. They don't need to be brushed once a day like your teeth. But they need some special care, especially if you like listening to music with earphones.

Maybe your mum or dad has told you, "Turn that down before you go deaf!" Well, they are quite right. Loud noise might cause hearing loss for a short time or even forever. Think that earphones are a good way to escape from tour parents’ eyes? Well. It may not be as good a way as you expect. American doctors have studied a group of 44,000 people who used earphones more than 15 hours per week. The doctors found that 37,000 of them were getting hearing problems.

If you use earphones for too long a time, your ears might feel painful. You could also lose your hearing for the rest of your life. So don’t wear your earphones too long. Use them less than one hour a day. Want sharp hearing? Don’t forget to do the following: Try to stay away from places where there is too much noise, like a disco. If you have to go, wear earplugs. When swimming, remember to put earplugs into your ears to stop water from getting in. Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out.

Keep these things in mind! Then you won't be saying "WHAT???" when you are older.

1.Using earphones "may not be as good a way as you expect" because _______.

A. your parents know what you're doing

B. it can cause hearing problems

C. it makes your parents angry

2.If you want sharp hearing, you should _____.

A. have your ears specially trained
