Older women who walk a little over three kilometers each day might live longer than less active women of the same age, a new study suggests.
Many Americans hoping to stay healthy set a daily goal of 10, 000 steps, or about eight kilometers. They often have this goal because they are wearing electronic devices which set that target, note researchers in the United States. Their findings appeared recently in the publication JAMA Internal Medicine.
But it is not clear how much intensity(强度)or speed matter when counting the health benefits of every step, the researchers write. They add that 10,000 steps per day might not be the right goal for everyone.
For the study, researchers observed 17,000 women, all in their early 70s. They asked the women to wear accelerometers for at least four days. Accelerometers are small devices that measure the number of steps and the intensity of movement. The researchers followed up with the women much later, around 4. 3 years later, on average. Since the beginning of the study, 504 women had died. Compared to women who took no more than 2, 718 steps daily, the women who took at least 4,363 steps per day were 41 percent less likely to die.
“Even a modest amount of steps is associated with lower death rates, "said I-Min Lee, the lead writer of a report on the study. "The rate of stepping did not matter in these older women: it was the number of steps that mattered.
The study had a few limitations. For example, the researchers only measured women’s movements once, at the start of the study period. It is possible that the women’s behaviors changed over time. Still, the results are "good news for older adults who may have difficulty walking at faster paces, "said Keith Diaz, a researcher at Columbia University. He was not involved in the study.
“Any walking is better than nothing, " Diaz said by email. "With even small amounts of walking, your risk of death will be sharply reduced "For those who have difficulty walking, other research shows that any form of aerobic activity provides health benefits," he added. "Swimming, bicycling or any form of activity that is continuous in nature will provide health benefits.
1.What conclusion can we come to from the text?
A.People who walk about 10,000 steps can live longer.
B.10,000 steps per day might be the right goal for people.
C.The more steps one walks per day, the longer life he may live.
D.The number of steps is important for a long life among older women.
2.How is paragraph 4 mainly developed?
A.By giving examples. B.By comparison.
C.By listing statistics. D.By explaining reasons.
3.What can be leaned from what Diaz said?
A.People who walk fast will get more health benefits.
B.If people have a habit of walking, the risk of death will be reduced.
C.People with walking difficulty can not benefit from activities
D.Activities such as swimming and bicycling are not as beneficial as walking.
4.Where is the text most likely from?
A.A medical journal. B.A news report.
C.A magazine about fashion. D.A traveler brochure.

Over 2. 5 quintillion (1018) bytes of data are created each day. Many of them consist of information that would allow people to be personally identified.
At the same time that we share our personal information, there is a growing concern with how that information is being gathered, stored, used and shared. While many economies like Canada and the EU have privacy laws dating back to the mid-1990s, changes to data practices in the past five years have motivated governments to review or update existing laws.
Changes to privacy laws are being fuelled by growing public concerns with the idea of unrestricted data accumulation and use. For instance, earlier this year, the World Economic Forum found that 1/3 of global citizens have no idea about how their personal information is used and that trust is lacking.
Privacy laws are changing to deal with the real and noticed risks of harm which result from the under-regulated or unregulated data economy. The EU has introduced big reform to laws which are aimed at protecting privacy. The EU's General Data Protection Regulation (GDPR) introduced strict requirements for those that control or process the personal data of the people who live in the EU. The GDPR's stated goals focus on the protection and basic rights of personal information. Certain US states are also entering the ring in the fight for control over personal data. They have passed or are actively considering privacy laws. California is out front. The California Consumer Privacy Act (CCPA) provides greater control to individuals over their personal information. There is a sense that privacy laws are on the near horizon in the US.
These are two examples that are actively pursuing more progressive privacy laws. One important consideration is to harmonize global standards for best law practices. This will ease compliance (遵守)across border and provide a valuable signal to the public that governments are keeping pace with rapid change.
1.What's the cause of the change of privacy laws?
A.A growing need for information. B.Public concerns over data security.
C.General awareness of data control. D.Collection of personal information.
2.How does Paragraph 4 develop?
A.By giving examples. B.By listing statistics.
C.By analyzing reasons. D.By making comparisons.
3.What is an important consideration for global law makers?
A.The practice of laws in different fields.
B.The reflection of reality in different eras.
C.The consistency of laws in different regions.
D.The adaptation to changes in different societies.
4.What is the passage mainly about?
A.EU passes new laws for privacy protection.
B.Governments ignore the violation of personal privacy.
C.Privacy laws are changing to protect personal information.
D.People lack the awareness of personal information protection.

Homelessness is a huge problem all over the world. It’s said that each day there are about 1 million people living on the streets in the US. It is a serious problem which should be dealt with effectively.
There are two main reasons for people leaving their homes: poverty and less affordable houses due to bad economic conditions. Other reasons include: domestic violence, divorce, and mental illness. Living without a home makes people main targets of violence activities and besides, these homeless people have to face the following difficulties on a daily basis.
They have to move about, carrying their belongings, which makes it difficult for the charity and the government to help them. They have limited access to bathrooms and restrooms and are forced to live in dirty conditions, making them easy to be attacked by diseases. They have limited access to health-care facilities in case of emergency, and almost no access to education as they have no money. They are often ill-treated by society, which makes them unfriendly, often ending up being involved in activities connected with crime like selling drugs or guns.
Homelessness is not something that happened overnight --- it has been in the country for decades. The society usually believes those living on the street to be mentally unstable. This belief is partially true. Most of them are normal people just like you and me.
The federal government is doing all it can to help but it is not enough, so the ordinary citizens have to stand up and try to help whenever it’s possible. There are various organizations, such as charity organizations that are working constantly to make sure that homeless people find a shelter to live in. the united efforts have helped millions of people return to their normal lifestyle. However, there is still a long way to go before a better situation is created for all the homeless.

阅读下面短文并回答问题,然后将答案写到答题卡相应的位置上(请注意问题后的词数要求)。
[ 1 ] Do you spend over an hour each day texting messages to your friends? Do you frequently ignore work, study, and other activities to check your phone for messages? Are you anxious and restless if you are separated from your mobile phone,9 Do you hardly ever use your phone to talk any more, and do your thumbs hurt from texting too much?
[2] If ________ , then it is very possible that you are a textaholic. A textaholic can be defined as someone who is addicted to sending and receiving messages. The main symptoms are a strong desire to text messages, which takes precedence (优先)over everything else, and bad moods, low spirits and a lack of self-confidence if messages fail to come in. The root of the problem, as with many addictions, is the desire to escape from emotional difficulties such as stress, atrxiety and relationship problems. Experts warn that text addiction is likely to become the most common form of addiction in the future, especially among the young.
[3] So what can you do if you think you may be a textaholic? The key is to get your life back in balance. Make sure you resist the urge to answer every message you receive, and consider leaving your mobile phone behind occasionally when you go out. Most importantly, make a point of spending quality time with friends and family, and make time to re-learn the art of face-to-face conversation instead of conducting your relationships by means of text messages. Not only will you save time and money, but you may also rediscover the pleasure of true communication.

My First Day of School
Fear started taking over, I was walking into my first school in America. I had traveled a long distance from India in order to join my parents, who had been for three years, hoping America would help my future. My father decided that I would be better off going to school here, so I enrolled(登记) in the local high school in my new town.
I was afraid how I would do. On the first day, I went to my second period class after I had missed my first. With anxiety, I reached for the door, opening it slowly. Without paying attention to my classmates, I went straight to the teacher and asked if this was the right class. With a soft voice he answered. “Yes.” His voice comforted me a little. He gave me a sheet called Course Requirements, which I would never get in India because we didn’t have anything like that. Then he asked me to choose where I would sit. I didn’t actually want to pick a seat. In India we had fixed seats, so I never needed to worry about that. I spent the rest of the class taking notes from the image produced by the overhead projector. In Indian schools, we didn’t use the technology we had. We had to take notes as the teacher spoke.
It was noon. I was very confused about when I would have lunch. I went to my next class and the bell rang as I entered. I went through the regular process of asking the teacher if I was in the right class. She said, “It’s still fourth period.”
“But the bell just rang,” I said.
Changing from a gentle tone to a harsher(刺耳的)one, she said, “That is the lunch bell, young man.”
I apologized. Without another word I headed for the cafeteria. I felt lucky because we didn’t have this in India. Every confusion seemed like a barrier I had to get through to reach my goal. At the end of the day, I was on my way to the bus which we didn’t have in India either. I spotted my bus and sat down inside happily. I was thinking, today wasn’t so bad.
