Do you want to live another 100 years or more？Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.

“I think we are knocking at the door of immortality(永生),”said Michael Zey，a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that's a conservative estimate（保守的估计）.”

At the conference in San Francisco，Donald Louria,a professor at New Jersey Medical School in Newark said advances in using genes as well as nano technology（纳米技术）make it likely that humans will live in the future beyond what has been possible in the past. “There is a great push so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”

However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less diseases, they say failure of the brain and organs will finally lead all humans to death.

Scientists also differ on what kind of life the super aged might live." It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life？" said Leonard Poon，director of the University of Georgia Gerontology Centre." At present people who could get to that point are not in good health at all."

    I grew up in a middle-class household in Australia. In terms of safety and standard of living，a comfortable lifestyle is all I ever knew，and as a result，I was not aware just how lucky I was.

It was a Monday，and a teacher told us about an oversea mission trip to Cambodia. I had never been overseas before，and I knew absolutely nothing about Cambodia，but something inside of me knew l needed to go on this trip.

I spent the next few months working on S7. 25 hourly wage at an awful fast food chain，saving every penny I earned. Just days before the trip was set to depart，I managed to hit my target.

I will never forget the moment I nervously stepped off the plane in Cambodia. I vividly recall the sight of malnourished （营养不良）children begging for money tearing at my heart. I saw what true poverty looked like as we went to hand food packages out at a massive garbage dump in the city，home to thousands of families，many of whom were forced to seek for food among the rubbish.

On the following days，I played with children who，despite living in hard conditions, were overflowing with joy and happiness. I met families who，despite having nothing，were some of the kindest people I'd ever met. For the first time，my eyes were opened to the reality that happiness is not defined by money. People here were rich in relationships and community，and shared with each other the little that they had.

Through the trip，I began to see the value of learning from people of other races，cultures and religions. I finally saw that there was a much bigger world outside of my little one，and experienced first-hand the beauty of human diversity.

B.She learnt to be independent.

C.She made friends with some locals.

D.She learned about the outside world.

    Mom noticed that something was wrong when I started getting so thirsty. I’d have a lot to drink before bed, which was unusual for me. One time, I opened a big container of apple juice and kept refilling my glass. Before I knew it, I’d drunk the entire container! My mom called my doctor. I then had a few blood tests, and the results were certain — I had diabetes (糖尿病), which meant that the amount of sugar in my blood was very high. That can be dangerous, so I had to learn how to control my blood-sugar level.

My eating habits had to change in a big way. With diabetes, I can’t eat a lot of sugar or carbohydrates (碳水化合物). I have to figure out exactly how much sugar I plan to eat, and then I get an injection of insulin (注射胰岛素) before the meal to help my body process the food. Also, I test my blood-sugar level often. I’m always trying to keep my blood-sugar at a healthy level. The level can drop when I exercise, but that doesn’t keep me out of gym class or off the basketball court — I just keep some juice boxes around to boost my blood-sugar if I need to.

It’s a lot of work and not a lot of fun — to keep track of everything, but I’ve gotten used to my new habits. I was a little scared at first because I wasn’t sure how my life would change. Once I knew what I needed to do, though, it wasn’t a big deal. My life is different now from what it was before, but it has become completely regular to me.

We should know how to avoid illnesses. Keeping hands clean are one of the most basic ways to prevent illnesses, especial when COVID-19 is widely spreading. Yesterday I taught my 3-year-old sister what to wash hands properly. Firstly, I made her to wet her hands under running water and apply soap to them. After she rubbed her hands well with soap to at least twenty second, I told her to wash off all of the soap. Lastly, I gave him a clean towel to dry her hands. She was very glad but showed me her clean hands. Look at her smiling face, I felt so happy that I gave her new storybook.

    It was a bitter, cold evening in Virginia years ago. An old man was waiting for a ride _______the river. The wait seemed _______. His body became stiff from the chilly wind.

_______, he watched as several horsemen approached. He let the first one pass by without an effort to attract his _______. Then another passed by, and another. Finally, as the last rider _______ him, the old man _______ the rider’s eye and said, “Sir, would you mind giving an old man a ride to the other side? ”

Pausing his horse, the rider replied, “Sure! Hop aboard.” Seeing the old man _______ to lift his half-frozen body from the ground, the horseman helped him _______ the horse.

As they got close to the destination, the horseman’s _______ caused him to ask, “Sir, I’m curious why? On such a bitter winter night, I ________ that you let several other riders pass by. You would wait and ask the last rider. ________ I had refused and left you there?”

The old man replied, “I ________ the eyes of the other riders and immediately saw there was no ________ for my situation. It was ________ to ask them for a ride. But when I met your eyes, ________ was obvious. I knew, your gentle spirit would give me ________ in my time of need.”

Those heartwarming comments ________ the horseman deeply. “I’m most grateful for what you have said,” he told the old man. “May I never get too ________ in my own affairs that I fail to respond to the ________ of others with kindness.” With that, Thomas Jefferson turned his horse around and ________ his way to the White House.

    Small talk is stressful for even the most easy-going people. 1. Below, small-talk experts share their best advice on developing good chatting skills.

Ask questions.

The key to good small talk is asking the other person a lot of questions. But avoid rapid-fire questions. 2. Be sure to express your own feelings in response to what they share.

Avoid conversation starters like “How have you been?”

You could not ask a more awkward question. A better way to produce meaningful conversation is to add “What is new in your life since the last time I saw you?

Avoid one-word answers.

3. When someone asks you a question, give them something to talk about with you, not a word or two. Fine said, if someone asks you, “How was your summer?”, you can answer, for instance. My summer was great. I’m excited about my vegetable garden. That will give the person something else to ask you about.

4.

Your facial expression and body language should let the other person know you’re truly listening to them. A recent study showed that people who used hand or head gestures received responses to their questions faster than those who didn’t.

Small talk may help you connect with someone new with whom you want to have a more serious talk. 5.

A.You don’t have to be a reporter.

B.Don’t worry about it too much, though.

C.You could not ask a more inconvenient question.

D.It’s the first step to any meaningful relationship.

E.Use your hands to keep the conversation flowing.

F.Don’t be a disappointing person in a conversation.

G.You should make a conversation with people you like.

    A team of over 30 Chinese surveyors left the base camp at Mount Qomolangma for a higher spot on its journey to the peak on Wednesday as part of the country’s mission to remeasure the height of the world’s highest mountain.

The remeasurement of the peak’s height is a part of China’s latest large-scale scientific survey of Qomolangma. Preparation of the project was started in early March, with 53 surveyors from the First Geodetic Surveying Brigade (大地测量旅) getting stationed near Qomolangma to carry out adaptive climbing and training in other technical skills, and they are going to the survey on the top of the mountain.

To ensure the accuracy of the measurement, and to work it in a more scientific way, experts from the Chinese Academy of Surveying and Mapping, the Shaanxi Bureau of Surveying, and the China Geological Survey were invited to assist in the technical design and planning of the project from the beginning.

The technical innovation and breakthrough applied in the latest survey include the application of the BeiDou-3 Navigation Satellite System and advanced domestic surveying and mapping instruments.

The Chinese government has conducted six large-scale surveys and measurements on Qomolangma in the past few decades; it had successfully measured and announced the height the mountain in 1975 and 2005. Chinese mountaineers and researchers climbed Mount Qomolangma in 1975 to determine its height and concluded that the rock height of the peak was about 8,848.13 meters, and in 2005, the summit measured 8,844.43 meters (29,017 feet).

1.Where does the text come from?

A.A story book. B.A science fiction.

C.A news report. D.A travel guidebook.

2.What ensures the accuracy of the measurement according to Paragraph 3?

A.Inviting many experts to support.

B.Applying adaptive climbing skills.

C.Planning the project in early March.

D.Using the most advanced mapping instruments.

3.Which of the following about the survey is true?

A.83 surveyors worked for the remeasurement.

B.This is the 7th large-scale survey of Qomolangma.

C.30 Surveyors were stationed near Qomolangma.

D.The height of Qomolangma must be shorter than before.

4.What’s the main idea of the passage?

A.The ways of remeasuring Qomolangma.

B.The results of measuring Qomolangma.

C.The technologies applied in remeasuring.

D.China’s remeasurement of Qomolangma.

    Smart cities promise to bring better lives, faster transport, cleaner air and lower crime, all through the intelligent use of connected technology, said experts, and after huge investment in the field, China is leading the way.

“China’s smart cities market increases about 30 percent year-on-year in 2018, and all the provinces have begun development and construction for smart cities, with more to follow,” said an expert.

“Although most cities have started a smart city project, there is no globally unified thinking on the concept and operation of smart cities,” said Franco.

Alibaba is now involved in dozens of pilot projects across China, with its open AI (人工智能) platform Tianqing for the ET City Brain system officially launched in September. Set up by its cloud computing subsidiary (子公司), the Brain looks to make the city “think” through AI and cloud computing technologies, and help make the best of public services in real time.

Since introducing the technology, Hangzhou’s traffic jam has fallen from the fifth-worst in China in 2016, all the way to 57th place this year. “Now our experiments are mostly for government use, but we truly expect our open AI platform to enter more areas and help citizens live, work and entertain better,” said Hua.

In McKinsey Global Institute recent report Smart cities: Digital solutions for a more livable future, they find cities can use smart technologies to improve some key quality life by 10 to 30 percent — numbers that translate into lives saved, fewer crime incidents, a reduced health burden, and carbon emissions.

1.What can we say about the smart city?

A.Its concept has not been accepted by people.

B.It can be achieved only by lots of investment.

C.The worldwide standard for it has been established.

D.Its progress in China is among the best in the world.

2.What does the underlined part in Paragraph 5 refer to?

A.Traffic jam. B.Traffic flow.

C.AI platform. D.Public services.

3.Hangzhou is mentioned as an example to show that _______.

A.its traffic problem has been settled

B.the city has become more intelligent

C.its public services have greatly improved

D.it has made achievements in smart city construction

4.What is the best title for the text?

A.Smart Cities are on the Way

B.Outline of the Future Smart Cities

C.Hangzhou’s Construction of Smart Cities

D.Alibaba Contributes More to Smart Cities
