Some artificial satellites are used for telecommunications, which enable us to make telephone calls to any part of the world, to see live television transmissions and to communicate via the Internet.Other artificial satellites are used for navigation (導(dǎo)航), so that people on Earth can know at any moment the position of an object, within a few metres.Others are weather satellites, launched to observe the state of the atmosphere and to follow the movement of the clouds as they gather.There are also military satellites, for the purpose of gathering information on the weapons and the troops in countries which may be unfriendly and also to indicate the launch of a missile (導(dǎo)彈)．

Each satellite has its own orbit which is selected according to its purpose.Communications satellites, for example, have a geostationary (與地球相對(duì)同步的) orbit.That is an orbit which turns at the same speed as the turning round of the Earth.Satellites used for weather forecasting pass over the two poles of the Earth.By doing so, a different part of the Earth’s surface is viewed on each successive orbit.All artificial satellites get the energy they need by huge solar panels which extend like wings.These are therefore controlled in such a way that they are always turned toward the Sun.

【1】The first manmade satellite was sent into space to ________.

The next day we went there with Kavya’s brother Vijay. He said, “Shout loudly if you need me.” Kavya climbed onto the water tank first and then she climbed down into the man’s house. I followed her. We were looking under a bed for the ball when we heard a noise. It was Vijay. “Mother is calling you，” he said in a low voice.

We hurried out taking the lost ball with us. Along with the ball was a surprise! But we had to leave the house quickly. When we reached Kavya’s house, the TV was on. It was news time. I couldn’t believe my ears when it said that 20 gold bars were stolen from a gold shop. They showed a picture of the gold bars, which were exactly like the one we had seen in the man’s house.

We told the story to Kavya’s mother right away, and she called the police. Soon the police caught the man. They found all the gold bars in his house. A few days later a policeman came to us and said, “Thank you for helping us catch the guy. Here is a bag for all of you.” When we opened it, it was full of storybooks and lovely toys. Standing beside us, Kavya’s mother was all smiles.

【1】The children decided to climb over the water tank ________.

What does a beautiful person look like? Well, it depends on whom you ask and 【1】 they are from.

Much like the way people with straight hair want 【2】(curl) hair or those with pale skin lie in the sun trying to get a suntan (曬黑), people often find themselves more attractive when 【3】(visit) another country.

Recently a post went popular on the US question website Quora. It asked, “Have you ever been considered more attractive in a country 【4】 than your own?”

Many replies made 【5】 clear just how much more attractive they were considered in other country, and why.

Lolyta from Indonesia wrote, “In my home country, I am not considered beautiful, 【6】 when I went to Europe I got a lot of attention.” Pooja Gautam from Nepal shared a similar experience. Women with lighter skin always got more attention than she 【7】 in her country. But in Poland, she has gotten 【8】(usual) high levels of attention from locals. “Tanning salons (曬黑沙龍) are a big thing in Polish cities,” she wrote. “Some Polish people find it hard to believe 【9】 I tell them that many Nepalese people carry 【10】(umbrella) on hot, sunny days to stop their skin from turning darker.”

Dear Tom，

How are you？I am just writing to tell you I had wonderful time at your place in New York.

I arrived home, safely and sound. I have something to ask for you.I have been looking through my bags for my favorite red shirt, or I can't find it somewhere.I'm sure I might have left it at your place. Could you look around your house for it? By the way, I am planning my parents' wedding anniversary celebration. I had already invited you and your parent.I wonder whether you would like to come to Chicago this time. What do you think of it？Take care of you and write to me soon.Giving my regards to Uncle Bernard and Aunt Norah.

Love，

According to technology news website, The Verge, flawed (有瑕疵的) phone batteries might be to blame.

Even if you are not a science student, you probably know that it is common sense that the negative end and the positive end of the battery should never touch. If they do, the battery will short-circuit (短路), causing a powerful electrical reaction that can destroy the battery and cause a fire.

This is why all lithium-ion (鋰離子) batteries – the kind that can be found in many of our devices (電子設(shè)備) like tablets and cameras – have a separator layer inside to stop the two ends from touching one another.

But somehow, the separators in some of the Samsung phones broke, causing explosions.

Overcharging is another problem that can make batteries heat up quickly. Fortunately, most batteries are designed to be able to automatically stop charging once they are fully charged. But again, this somehow failed to happen in some of the Samsung phones.

According to Lynden Archer, a materials scientist at Cornell University, US, we have already achieved 90 percent of the battery life possible from a lithium-ion battery. Customers’ demands that their devices get thinner and their battery have a longer life have given producers little choice but to try to put more power into thinner batteries. However, the more energy you put into a box, the more dangerous it’s going to be.

【1】A separator layer is put in lithium-ion batteries in order to ______.

A.ensure a longer battery life

B.reduce a certain electrical reaction

C.connect the anode and the cathode

D.prevent a battery from short circuiting

【2】What are the possible reasons for the Samsung phone explosions?

A.Pushing the limits of batteries.

B.Short circuiting and overheating.

C.Overcharging and thinner batteries.

D.Automatic charging and broken separators.

【3】What is the writer’s main purpose of writing the article?

A.To describe problems facing cell phone producers.

B.To warn us about the dangers of lithium-ion batteries.

C.To teach us common sense when it comes to batteries.

D.To explain the reasons for the Samsung phone explosions.

Fearmongering(散布恐慌)against China more dangerous to global economy than coronavirus(冠狀病毒)

After weeks of attempting to sow chaos and spread fear about the outbreak of the novel coronavirus epidemic(流行病)in China,some overseas media outlets and individuals have shifted focus 【1】 another battlefield-the Chinese economy. They paint a rather dark picture not just for the Chinese economy 【2】. for the global economy.【3】(they)articles are filled with scary headlines and exaggerated facts.People cannot help 【4】(panic)about the global economy. which is already facing serious challenges like trade wars. 【5】it comes to”causing”such a mess for the world,it is easy to point fingers at China.

Anyway,these media outlets are right about a couple of things.First,the epidemic will make the Chinese economy suffer a little.After all,consumers across the country are 【6】(trap)in their homes and businesses and factories have been shut for a good part of this year,Second,we have to be fully aware of these challenges and risks in order to address the problem.The first step to solve a problem is 【7】(recognize)there is one.

Actually,Chinese officials have been very clear about the potential impact of the epidemic on the economy.Why 【8】(will)they invest hundreds of billions of dollars into the economy if they weren’t aware of the problem?Why would they roll out a great number of measures to support businesses?Why would they take extraordinary risks in encouraging factories to restart 【9】(produce)?

【10】 of how severe the impact will be,the epidemic does not change the fundamentals of the Chinese economy.The outbreak is surely to be contained.It can be safe to say that fearmongering against China is more dangerous to global economy than coronavirus.

Eco City Farms in Edmonston,Maryland,is located near shopping centers,car repair shops and homes.The neighborhood is a working-class community.People do not have very much money,and they have limited access to fresh food in markets.

Over the past two years,the farm has attracted volunteers from the community like Marcy Clark.She schools her four children at home.On a recent day she brought them to Eco City Farms for a lesson.Alston Clark thinks his experience very valuable.”I like coming out here.” he says,”You know,you connect with the earth,where your food comes from.You appreciate the food a little bit more.”

Margaret Morgan-Hubbard started Eco City Farms.She thinks of it as a place where people can learn to live healthier lives.”Growing food in a community and showing that you can have farms even in the city is helpful to strengthen the relationship in that community and brings people together, “she says. “Every piece of what we do here is a demonstration to show people everything about how to have a sustainable community. “From the Eco City Farms people come to know that they are not only growing food and raising chickens and bees,but improving the soil with compost(堆肥)made from food waste.Sixteen wooden bins are filled with worms.Their job is to eat the food waste and help make it into compost.

Eco City Farms is an experimental operation.The farm gets its power not from the local electricity networks but from the sun with solar panels.In winter,the greenhouses are heated using a geothermal(地?zé)岬?/span>)system.

Vegetables can be grown all year.So once a week,all winter long,neighbors like Chris Moss and her three children bicycle to the farm to pick up a share of the harvest.

“I like eating the vegetables,”says five-year-old Owen Moss.
