Satellites are an important part of our ordinary lives.For example, the information for weather forecasts is sent by satellite.Some satellites have cameras which take photographs of the Earth to show how clouds are moving.Satellites are also used to connect our international phone calls.
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites.Airplane pilots also sometimes use a satellite to help them find their exact location.
We use satellites to send television pictures from one part of the world to another.They are usually 35,880 kilometers above the equator.Sometimes we can see a satellite in the sky and it seems to stay in the same place.This is because it is moving around the world at 11,000 kilometers an hour—exactly the same speed that the earth rotates.A satellite must orbit the Earth with its antennae(天线)facing the earth.Sometimes, it moves away from its orbit(轨道),So there are little rockets on it which are used to put the satellite back in the right position.This usually happens about every five or six days.
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth.A satellite usually works for about 10-12 years.Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired.Often,very old or broken satellites are left in space to orbit the Earth for a very long time.This is very serious because some satellites use nuclear(核) power and they can crash into each other.
1.Which of the following is NOT done by satellites according to the passage?
A.Sending information for weather forecast.

Advertisement is an important part of our lives. We are so used to them that we often do not even realize how many we see and hear in a day!
What is an advertisement?
An advertisement provides information and uses creative languages and attractive pictures to encourage people to buy a product or service or believe in an idea. Newspapers, magazines, the Internet, radios and televisions are the most places to find advertisements. There are two main types of advertisements—commercial advertisements and public service advertisements (PSAs). A commercial advertisement is one which someone has paid for to promote(提升) a product or service. PSAs are often placed for free, and are to used to educate people about health, safety, or anything that affects public welfare(福利).
Does an advertisement tell people the complete truth?
China has strong laws to protect people from advertisements that lie or try to make people believe untrue promise about products or services. However, we still must be careful with the methods used in advertisements to try and sell us things. Even if an ad does not lie, it does not mean it tells the complete truth. One toothpaste ad says “Bright-teeth fights bad breath!” the advertisers want you to read the word “fights” and think that the toothpaste cures bad breath, but it does not say that! We must not fall for this kind of trick!
Public service advertisements.
Not all ads play tricks on us though. PSAs use some of the same methods, but they are made to serve the public. PSAs are meant to teach us and help us lead better lives. You have probably seen or heard some of them yourself, like “Yes to life, no to drugs” and “Knowledge changes life”. These ads deal with large social issues(问题). There are also PSAs that educate people about public service projects, such as Project Hope. All of these ads are meant to be helpful, and you can often learn a lot by following the advice they give.
Try to remember: think about why you should do or buy the things the ad suggests. We all want to be smart about what we believe, so be smart about advertisements.

Nowadays, computers and Internet are playing an important part in our life. We usually need to set passwords(密码) when we use computers and Internet. In order to keep our accounts (账户)and personal information safe, we must learn how to set safe passwords.
Experts have some useful advice for you. You’d better remember them. First, make your password out of capital(大写的)letters. It only takes a hacker(黑客)10 minutes to work out a 6-letter password made of small letters. But the same password in capital letters takes 10 hours to work out. Second, add numbers or symbols to your password. It may be much safer. Third, never use personal information for passwords and use different passwords for different accounts. At last, a user should change his or her passwords every 90 days. In this way, hackers won’t guess your passwords.
1.What do we usually need to do when we use computers and Internet?
2.Why must we learn how to set safe passwords?
3.How many pieces of advice are given to us by the experts?
4.Is it safe to use personal information for passwords?
5.How often should a user change his or her passwords?

Social Bond of Animals
Friendship is an important part of human life. Friends can share our joys and our hardships. We aren’t alone. Many different animals also make friends.
Recently , a British research team finished an eight-year study of Indo-Pacific dolphins off the coast of Western Australia. These dolphins can use different tools to search for food. The researchers found that these dolphins are more willing to hang out with partners that like the same tool. Other factors, like family closeness or sex, have no influence on this relationship.
“It suggests that dolphins form social bonds (纽带)based on shared interests,w UK biologist Simon Allen told Science Daily. "Using different tools is time-consuming (耗时间的)” for dolphins to cooperate.
Apart from dolphins, elephants, horses and bats are also known to form friendships. Are friendships only limited to the same species? Of course not, The
Atlantic reported in 2015, a goat Timur was originally left in the tiger Amur's enclosure (围场)as a meal. But instead of eating Timur, Amur likes to play with it and gets jealous when others are close to his friend.
The Atlantic said it’s not unusual among captive (圈禁的)animals. That's because in captivity, animals don’t need to spend much time and energy marking their territory (领地)or looking for mates the way they would in the wild. They are actually more likely to feel bored. " In this particular situation, the animal's motivation to engage (参与)socially and playfully may be higher than eating. n
More interestingly, animals not only make friends but also try to keep lasting friendships. Take bats for example. In 2011, scientists found bats prefer to hang out with a few certain friends, keeping loose ties to the rest of their group.
Humans aren't so different. “We do not work, play and live together with the same friends all the time," Swiss zoologist Gerald Kerth explained. “ But nevertheless, we are able to maintain long-term relationships …despite our often highly dynamic (动态的)social lives."
1.What did the recent British research find about dolphins?
A.They form a group to look for food together.
B.They form friendships based on family closeness.
C.They are likely to make friends based on interests.
D.They are better at building friendships than other animals.
2.What can we infer from Gerald Kerth’s words?
A.Animals like to hang out with different friends.
B.Animals might feel bored with friends of the same species.
C.Humans are better at keeping long-term bonds than animals.
D.Humans and animals make and keep friendships in similar ways.
3.What's the passage mainly about?
A.How animals form and keep friendship.
B.The importance of friendship for animals.
C.How to build strong ties with your friends.
D.The different ways humans and animals socialize.
