Did you hear the song called Heartbeat? It's very {#blank#}1{#/blank#} in the world. Zade Dirani released (发布) this song {#blank#}2{#/blank#} March 15^th 2018 to remember the seven years of war (战争) in Syria. In the song, one of the {#blank#}3{#/blank#} is Ansam. She is a ten-year-old girl. When she was born (出生), she couldn't see {#blank#}4{#/blank#}. But later people found she could sing very well. She sang the song Heartbeat with another 40 children. They all lost their parents in the war. In this song, children hope (希望) they can have a happy {#blank#}5{#/blank#} and there is no war in Syria. But many people lost their homes {#blank#}6{#/blank#} the war broke out (爆发) on April 13^th 2018 again. Everybody hopes the war can {#blank#}7{#/blank#}. We hope all the kids have food to eat. They can live with their parents. They can study in the classroom. They can sing under the trees and swim in the sea.

    We are lucky to live in a great {#blank#}8{#/blank#}, China. Now we have food to eat. We are {#blank#}9{#/blank#} in the classroom. We {#blank#}10{#/blank#} reading books in the library. So we should study hard and love our parents and friends.

Differentweather makes people feel different. It influences health, intelligence andfeelings.

InAugust, it is very hot and wet in the northern part of the United States.People there have heart trouble and other kinds of health problems during thismonth. In the Northeast and the Middle West, it is very hot at some times andvery cold at other times. People in these states have more heart trouble afterthe weather changes in February or March.

Theweather can also influence intelligence. For example, in a scientific report,IQ of a group of students was very high when a very strong wind came, but afterthe wind, their IQ was 10% below. The wind can help people have moreintelligence. Very hot weather, on the other hand, can make it lower. Studentsin many schools of the United States often get worse on exams in the hot monthsof the year（July and August）.

Weatheralso has a strong influence on people's feelings. Winter may be a bad time forthin people. They usually feel cold during these months. They might feelunhappy during cold weather. But fat people may have a hard time in hot summer.

Low air pressure may make people forgetful. Research shows that people leave more bags on buses and in shops on low-pressure days. However, at about 18℃, people become healthier and stronger. People feel best at this temperature.

Areyou feeling tired, forgetful or unhappy today? It may be the weather's problem.

The Internet is one of the greatest inventions in human history.However，this great invention has some problems.Everything you do online leaves a small track（痕迹）.

Some people make use of the information you are providing for the Internet.How should you make your work online safer？There are a few steps.

Cover your tracks.Whenever you visit a website or a small file，a cookie（网络跟踪器） is marked in your browser（浏览器）

So what's the harm in the cookie？Well，bad people can use the information stored in your cookies to steal your passwords for some sites.So cut out all the cookies you have left as soon as you finish your work online.

Use the latest browsers.The main browsers，Chrome，Internet Explorer，and Safari are all built to be safe enough，but the people who create the browsers are not perfect and may make mistakes.It's common for a safety problem to come out with a browser.

Usually these problems are worked out very quickly，but it's important that you make sure your browser is up to date.In fact，new safety patches（安全补丁），but you need to make sure you have them.Turning on automatic updates（自 动升级） is the smartest choice.

Any technology has two sides.So we should be smart enough about them.

Pictures are falling off the walls. Lights are waving. Bed is shaking. Everything is moving. What's going on? It's an earthquake. 

Earthquakes are horrible disasters(灾难）and some of them are destructive, The top layer of the earth is made up of huge pieces of rock. They move past each other all the time along fault lines(裂纹线）. But sometimes two pieces get stuck together. When they finally move away from each other, they move suddenly. And this makes the land above them shake. This is the most common cause of earthquakes. 

During a small earthquake, you will feel a little shaking. But during a strong one, you will be thrown about. A strong earthquake is very horrible. Cracks will appear on the ground and windows and doors will break. Buildings will even fall down. So watch out! I f an earthquake happens at sea, it can make big waves called "tsunamis" (海啸). When these waves reach land, they can destroy villages. 

Earthquakes are measured on a scale of 0-9. It is called the Richter scale. A size 9 earthquake is the strongest and most dangerous. Since 1900, more than two million people have died in earthquakes. In 1976, a size 7. 8 earthquake hit Tangshan, China. It killed more than 240, 000 people!

Many earthquakes happened in China, so it is important for us to know what to do when an earthquake hits. Here are some tips on how to stay safe in an earthquake. 

Indoors

※Hide under a desk or bed. Stay away from windows and anything that could fall on you. 

※Do not get into a lift during an earthquake! When an earthquake has ended, stay under the desk until it is really safe to get up. 

※Open a window and get out of the building quickly if the gas line in your house is broken. 

Outdoors

※Move away from buildings and street lights. 

※Do not run outside if you are in a shop and far from the door. 

※Make sure you wear shoes after an earthquake. There may be broken glass on the ground. 

For two centuries, the famous University of Cambridge debating society has hosted many prominent figures from world leaders to scientists to comedians.

On Nov 21, the Cambridge Union hosted another extraordinary guest—a non-human debater called Project Debater. Designed by IBM, Project Debater is a machine that uses Artificial Intelligence (AI) to form a spoken argument. It can even listen and answer to opposite statements, much like a real person.

In the Cambridge test debate, it argued the topic: AI will ultimately（最终）do more harm than good. Before the debate, more than 1,100 arguments for the positives and negatives of AI were submitted（递交）to the IBM website. The machine then analyzed these sources and formed the basis of its arguments in minutes. Project Debater then showed off its AI by arguing for both sides of the debate.

Over a four-minute speech, it argued first that, "AI can only make decisions that it has been programmed to solve while humans can be programmed for all situations."

In support of AI, it then argued that AI would create new jobs and "bring a lot more efficiency" to the workplace.

This isn't the first test for Project Debater. In June 2018, the machine went back-and-forth for 20 minutes against champion debater Harish Natarajan. 

According to New Scientist, on both occasions, Project Debater repeated points and didn't always sufficiently support them.

Speaking to Cambridge Independent, Noam Slonim, the project's lead engineer, said, "The AI is not perfect, but it's going in the right direction." The team hopes to improve the AI by researching why humans find certain arguments more persuasive than others. They also hope the test might provide well-informed viewpoints for society, governments and private companies.
