The Advantages of Using Wi-Fi on Your Smartphone
Wi-Fi is a method for devices such as smart phones 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 smart phones 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 whentransferring larger files If you
need to download large files or stream media to your smart phone in a hurry, it is much better
to do so via Wi-Fi.
Battery life is extremely important for smart phones 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.
1 The following are the advantages of using Wi-Fi on your smart phone EXCEPT that _.
A it does not need a hotspot to connect all your mobile devices
B it is faster than the 3G cellular networks
C it is cheaper than using the 3G networks
D it makes your phone run more efficiently in the long run
2 By using Wi-Fi, you _.
Trang 2A can use all your bundled data for free
B can use a certain amount of data for free each month
C may stay under the data capacity allocated by mobile providers
D save your bundled data for situations when you use a Wi-Fi network
3 A Wi-Fi connection offers _.
A better large files B faster smart phones C no need for hurry D better speeds
4 Using Wi-Fi offers longer battery life because _.
A you will be able to connect to other devices when your battery is low
B it requires less time with the same task than using mobile networks
C the Internet harms the battery life so much
D it requires so little energy while the cellular coverage fluctuates

VII Read the text carefully and then choose the best answer.
In the last 100 years, technology has completely changed the way we live At the touch of button, we can look up almost anything we need to known on the internet We have electricity, aeroplanes, television, and we have ever been to the moon So what sort of inventions will there be in the 21st century? Indeed, is there anything important still left to invent?
It seems that there is Scientists all over the world are looking into nanotechnology with a great deal of interest This is the science of building small machines – when we say small, we mean very small To give you an idea of the scientists are talking about, these machines would be a million billion times smaller than the smallest bit of dust
Nanotechnology will bring about enormous changes Doctors, for example, will be able to cure any illness The environment will be improved because it will be possible to take the polluted air we breathe and make it clean again But perhaps the most exciting thought of all is that we won’t have to wait a thousand years for nanotechnology – many people believe there is a good chance it will come in our lifetime
