Everytime you are going to connect to the internet, you must protect your computer. If you don’t, it is like leaving your door wide open for robbers. You’ve probably heard everything such like computer virus, hacker, firewall, spyware and a lot more. Perhaps, you think that the anti-virus application that came along with the computer is enough to keep you safe, right? Wrong ….

First of all, you need a firewall. This is your first line of protection, causing it highly troublesome for some hacker to get through. However, nothing is perfectly unbreakable, but anti-virus software shall always watch for anything suspicious that disturb your computer and having an anti-virus software is important.

But there are things that can get into your computer in the unusual ways. It can be accidently added by you when you tried to download music, screensavers or pc games onto your computer. It can even be downloaded by someone you know and trust, like a friend. This malicious software is called spyware and its threatening, it can break out your privacy which allows people or computer programs to discover what you’re doing, what sites you are viewing and even log your keystrokes so that they can find out the characters you type in, such as passwords and credit card details. The most fundamental thing to protect your system against spyware is to install a powerful software that catch and removes it.

Well, you have your firewall and your anti-virus software in place. Probably, you think that an anti-spyware application is only money down the drain. That is not true. This software would fill up the gaps leftover by your other security application, and it will be like closing all your doors and windows and having a warning signal system equipped before you’re leaving your computer, but some highly skilled hacker can still break in if they really wanted to.

Task 1. Read the text and mark the sentences TRUE/FALSE. Correct FALSE sentences

1) You don’t need to protect your computer when you are going to connect to the internet all the time [1]

2) Having an anti-virus software is important [1]

3) You can get a spyware by downloading pc game from the internet [1]

4) An anti-spyware application is only money down the drain [1]

I live in Newquay. It’s a small town on the Atlantic coast in the south of England. It has got great beaches and is the best place to surf in the UK. There are lots of surf schools where you can learn how to surf. I go surfing with my friends every weekend. My favourite place is Fistral Beach.
I love Newquay because there are lots of other things to do as well as surfing. If you like water sports, you can go kayaking, water-skiing or coasteering. Coasteering is different because it is rock climbing, jumping into the sea and swimming in the same activity, but you should always go with a special instructor.
If you like animals, you can also visit the Blue Reef Aquarium and see lots of different fish and even sharks. You can also go horse riding on the beach or visit Newquay Zoo. There are lots of other attractions too like mini golf and bowling. Come and see for yourself!
Eg: Newquay is near the coast. True
1. Newquay is in the north of England. __________ [1]
2. There are many surf schools. ____________ [1]
3. Alex and his friends go to surfing every day. ___________ [1]
4. Coasteering is smaller to surfing. ___________ [1]
5. There is a ZOO in Newquay. ____________ [1]
