Read the passage carefully, then choose the correct answers.

The last two decades have seen enormous changes in the way people's lives are affected by IT. Twenty years ago, few people had access to a computer whilst today most people use them at work, home or school and use of e-mail and the Internet is an every day event.

These developments have brought many benefits to our lives. E-mail makes communication much easier and more immediate. This has numerous benefits for business, commerce, and education. The World Wide Web means that information on every conceivable subject is now available to us. Clearly, .for many people this has made life much easier and more convenient.

However, not all the effects of the new technology have been beneficial. Many people feel that the widespread use of e-mail is destroying traditional forms of communication such as letter writing, telephone and face-to-face conversation. In addition, the huge size of the Web means it is almost impossible to control and regulate. This has led to many concerns regarding children accessing unsuitable websites. In conclusion, developments in IT have brought many benefits, yet I believe developments relating to new technology in the future are likely to produce many negative effects that will need to be addressed very carefully.

The Advantages of Using Wi-Fi on Your Smartphone

Wi-Fi is a method for devices such as smartphones to connect wirelessly to the Internet using radio waves. Connecting to the Internet using Wi-Fi requires a hotspot, but it is always faster than the 3G cellular networks which smartphones can also use to connect, and occasionally faster than 4G. Using Wi-Fi when it is available can also prove to be cheaper and make your phone run more efficiently in the long run than relying on cellular networks.

When you use a Wi-Fi network to access the Internet from your phone, the data usage does not count against your bundled data. Mobile providers often allocate a certain amount of data for free each month and charge you a fee for any data usage beyond this. By connecting via Wi-Fi wherever it is available, you can save your bundled data for situations when you might not be close to any Wi-Fi hotspots.

In many situations, your speed using a strong, dedicated Wi-Fi connection is faster than that of using your mobile network. It is very noticeable when transferring larger files. If you need to download large files or stream media to your smartphone in a hurry, it is much better to do so via Wi-Fi.

Battery life is extremely important for smartphones because you will not be able to connect to the Internet or use certain functions such as the camera flash if your battery is too low. Using Wi-Fi to connect to the Internet drains less battery life than using a mobile network, especially in situations where the cellular coverage fluctuates. Since Wi-Fi is generally faster than using mobile networks, you will also not spend as much time transferring the data, which further decreases battery usage.

The following are the advantages of using Wi-Fi on your smartphone EXCEPT that          _______.

Nowadays, amid the storming development of high-tech devices such as smartphones or e-book readers, people seem to neglect the existence of certain inventions that date back thousands of years. One of those is the mirror.

People grew a desire to see themselves as they saw their reflections in the surface of water. Around the 600s BC, the first mirrors were made from natural materials such as polished stones. After a while, people started to use bronze, gold and silver to make mirrors. These metals were heavy, so mirrors had very modest sizes. Ruling-class people, especially ladies, used them as a fashionable accessory. Hardly did they go out without a mirror. In the 1st century, the first glass mirrors were invented by the Romans and were made bigger to allow people to look at the whole body. However, not everyone cherished the mirror. Some people were irritated to find themselves ugly looking at the mirror, and there were rumors that what they saw in the mirror were reflections of sins and demons.

Nowadays, despite technological advancement, mirrors still play important roles in various modern-day fields, such as surgery, transport, architecture and so on. In fact, mirrors are utilised in technology and have inspired the inventions of several devices such as cameras or satellites.

When were the first mirrors made?
