Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions

As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things. Pollutions in water are not simply a matter of “poisons” killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organisms to be affected are either plants or plankton. But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die in this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river’s edge or on the sea shore that people realize what is happening. Where do the substances which pollute the water come from? There are two main sources – sewage and industrial waste. As more detergent is used in the home, so more of it is finally put into our rivers, lakes and seas. Detergents harm water birds dissolving the natural substance which keep their feather waterproof. Sewage itself, if it is not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful since there are many high poisonous things in it, such as copper and lead. So, if we want to stop this pollution, the answer is simple, sewage and industrial waste must be made clean before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once. 

According to the passage, the way to stop water pollution is ...........

The Rise of Robots As kids, our grandparents frequently scared us by talking about how difficult life was when they were growing up. They mentioned walking miles to school in the snow, or doing hours of manual labour for little pay. Life has changed greatly since then, and it seems to get easier year by year. In fact, with the help of robots we soon might have to do much at all. But is this a good thing? By 2030, it’s estimated that robotics will be a $10 billion business worldwide. Companies are already starting to integrate them into the workforce. The electronics manufacturer Foxconn is drawing up plans to launch a factory within the next 10 years that’s completely staffed by robot workers. Meanwhile, an American company Briggo has invented a robot that serves gourmet- quality coffee to customers. With the push of a button it will crush coffee beans, measure exact quantities of water, and even wave a steam wand to ensure customers get the perfect cream on top. Unlike human baristas, it can serve multiple drinks at once and work all day and night without a break. Robots are also invading our homes. The Rooma is a mini-robot that vacuums rooms automatically according to a schedule. The Robomow is a device that will cut the grass for you while you sit in the shade. Then there’s the Nanda clocky, an alarm clock that makes sure that even the deepest sleepers get up on time. The clock is attached to a pair of wheels, and it will randomly move around the room. Once you finally catch it, you’re probably too awake to hit the snooze button. Although these early home robots are somewhat basic, they will likely become more capable as times goes on. Although robots certainly help us to eliminate tedious tasks, many people are concerned about a future filled with robots. Some fear that humanity will start to decline if machines do everything for us. Others have even warned about the robot rebellion, in which robots become so smart that they may decide to turn on their masters. These ideas may seem a bit far-fetched, but there are certainly lots of questions that need to be answered before everyone opens up to the idea of a robotic future. 

How is Briggo’s invention superior to human workers?

According to the passage, what must the nations of the world do to find a solution?

THE PEOPLE BEHIND THE MUSIC Think for a moment about the last music album you bought. Most likely, you’ll think of the singer or band that made you want to buy the album. You might even know the name of the guitar player or the drummer. Those talented performers, however, are only some of the people in the music industry work behind the scenes, but the roles they play in the musical progress are very important. Songwriters: Songs begin with the songwriter. Some songwriters work alone, but many work in teams that combine the talents of a lyricist, who writes the words to songs, and an instrumentalist, often a piano player or guitarist, who writes the music. Many of today’s pop stars work with songwriters. For example, some of Lady Gaga’s biggest hits were written by Nadir Khayat, also known “RedOne”. Some songwriting teams have become very famous, such as Mike Stock, Matt Aitken, and Pete Waterman, who were responsible for many big 1980s pop hits. Arrangers: After a song has been written, music arrangers make it more appealing by deciding which instruments will be used, what tempo, or speed, the song will have, and whether the song should have a lower or higher pitch. A good arrangement can bring a song to life and make it a classic. Studio Musicians: Not every singer or instrumentalist can be a star, and many work in the background as studio musicians. These artists are not a part of any one musical group. Instead, they are hired for recording sessions that eventually become the albums you buy, as well as soundtracks for television shows, movies, and radio ads. Recording Engineers: Recording engineers also play a major role in creating the final sound that you hear. First, these engineers set up the recording studio, the room where the performers play, placing musicians and microphones in exactly the right places to get the best sound. Next, they use electronic equipment, such multi-track recorders, to capture the music. Finally, long after the musicians have gone home, recording engineers use a mixing board to balance the melodies and rhythms of each musician, and sometimes to incorporate special sound effects or additional tracks. Many people make a living with music. You may not recognize all of their names, but all of them work together to create the songs you love to listen to. 

Which piece of equipment is used at the end of the recording process?

How to protect children Web fans from unsuitable material online while encouraging them to use the Internet has long been discussed in the US. For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as hazard and with good guides, some education, and a few precautions, the wilds of the Internet can be safely navigated. “Kids have to be online. If we tell our kids they can’t be allowed to surf the Internet, we’re cutting them off from their future,” said an expert. Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way would be to use what is known as a “content screener”. But this can’t be wholly reliable, and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing the Internet. A few other tips as follows: Don’t put the PC in a child’s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity. Ask your child what he or she has been doing and about any friends they make online. Tell your child not to give online strangers personal information, especially like address and phone number. And tell your children never to talk to anyone they meet on line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.

Facebook is a for-profit online social media and social networking service. The Facebook website was launched on February 4th, 2004 by Mark Zuckerberg, along with fellow Harvard College students and roommates. Since 2006, anyone age 13 and older has been allowed to become a registered user of Facebook though variations exist in minimum age requirement, depending on applicable local laws. Over 25 million people in the Uk use Facebook. That’s 45% of population! And on average, each user spends over six hours a month on Facebook. Though not the highest this is a considerable number. Is Facebook is a dangerous obsession or just harmless fun? Seventeenyear-old Bethan has written on her blog about what it was like to stop using Facebook. I think I am a Facebook addict. I log on to Facebook everyday to chat to my friends real friends and loads of online friends. Sometimes I have ten conversations going at the same time. I upload photos and update my Facebook profile all the time. But recently I’ve started to feel worried if I am offline for more than a few hours. And then last week I forgot to meet a real friend because I was online! I’ve realised I could have a problem. So I’ve decided to give it up for a while. I found it really hard. Facebook and my friends demanded to know why I had left. I spent the first few evenings wondering what everyone was chatting on Facebook. I even phoned a couple of friends to find out. The fourth night I wasn’t quite so bad. I actually concentrated on my homework better and I had more time to watch my TV programmes. And I spoke to my friends during the day at school. At the end of the first week, I reactivated my account, I think Facebook is fun and it’s useful for posting messages to friends and sharing photos. But I’ll try not to spend so much time on it in the future.
