Exercise 3. Read the passage, and choose the correct answer A, B, C or D for each question.
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.
1. The following are the advantages of using Wi-Fi on your smartphone 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 ______.
A. 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 smartphones

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 now
B. it required less time with the same task than using mobile networks
C. the Internet harms the battery life so much
D. it required so little energy while the cellular coverage fluctuates
5. The word “drains” in the last paragraph is closest in meaning to ______.

C. increases

D. reduces

Exercise 4. Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to
each of the questions.
THE VANISHING INVENTION
In 1998, a Valencian professor made an amazing claim. Professor Antonio Cervilla discovered how to use
water as a substitute for petrol. The scientist said that you could drive from Bilbao to Valencia on just half a litre

of water. His invention uses a molybdenum compound to break down water into hydrogen and oxygen. Unlike
other methods, no electricity is required and the reaction happens at atmospheric temperature. This impressive
technology is based on the way plant enzymes break down water. The use of molybdenum is the perfect choice
because, although rare, it is cheap and found all around the planet.
Since the claims were made, nothing more has been heard about this fabulous technology. There is no
explanation for the disappearance anywhere on the internet, apart from a list of similar inventions which have
also vanished. An inventor from the Philipines called Daniel Dingel developed a water-fuelled car but was
arrested and sentenced to 20 years in prison. If this technology were to become widely available, it would prove
disastrous for petrol station owners and would also save the planet from the impending environmental
catastrophes being caused by pollution.
1. The word “substitute” in the passage is closest in meaning to ____.
A. addition

B. alternative

C. imitation

D. solution

2. Which of the following is NOT true about Cervilla’s invention?

C. petrol

D. water

4. The word “vanished” in the passage is opposite in meaning to ____.
A. appeared

B. produced

C. introduced

D. invented

5. It is stated in the passage that water-fuelled cars may contribute to ____.
A. save energy

B. save environment

C. save money

D. save time

Exercise 5. Read the passage and choose the best answer A, B, C or D to each question.


There are thousands of other inventions that have contributed to the lives of humans across millennia. Many
of these inventions have even benefited animals and other living species. The reason behind every invention is

the need for it.
The main quality of an inventor is his or her ability to see what others are able to see. While most of us see a
blue sky, some are able to see the patterns not in the sky which leads them to investigate more. Another
important

quality

of

an

inventor

is

his

or

her

desire

to

find

a

solution

to

a

problem.

They keep abreast with the difficulties faced by human beings and focus on resolving them.
Many of the inventors we have mentioned above were not recognized by their teachers nor their peers. They
often had eccentric personalities and maintained unusual routines. For example, Albert Einstein was not
comfortable with the teaching methods in his school and preferred to teach himself complex subjects such as
mathematics and algebra. He dressed eccentrically and kept an unusual hairstyle and was often ridiculed for his
views. However, his uniqueness is what led him to change the way we approach the philosophy of science and
brought about the ground-breaking theory of relativity.
Inventions are any new discoveries that change the way we view our world. They can occur in art, sciences,
tools, machines, society, and even thoughts. Any process, composition, device, or method that expands the limits
of human knowledge, creativity, experience, or capability is called an invention and can be brought about by
any human who dares to think out of the box.
1. What is the best title of the passage?
A. Inventions Benefit Both Humans and Other Living Species
B. Important Qualities of an Inventor
C. Necessity is the Mother of Inventions

Examples of AI
Artificial intelligence (AI) seems to be everywhere, and it has great impacts on our daily lives. Not long ago,
only satellite-based GPS was available, now artificial intelligence can help users much more experience. It can
recommend the route that avoids roadblocks or congestion.
Using virtual filters on our faces when taking pictures and using face ID for unlocking our phones are two
more examples of artificial intelligence that are now part of our daily lives. AI can identify incorrect usage of
language and suggest corrections in word processors or texting apps. The apps with high-quality language data
can help you use grammar correctly. catch your mistakes and offer correction.
Interacting between customers and customer service can be time-consuming and stressful. One increasingly
popular solution to this is the use of AI chatbots. Advanced chatbots no longer require specific formats of inputs,
for example yes-no questions. Chatbots are taught to answer complex questions requiring detailed responses.

Exercise 7. Read the passage and write True or False next to the sentences.
James Watt (1736 - 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on
Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was
fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of
the world.
While working as an instrument maker at the University of Glasgow, Watt became interested in the
technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by
repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser,
which avoided this waste of energy and improved the power, efficiency, and cost-effectiveness of steam engines.
Eventually he adapted his engine to produce rotary motion, greatly broadening its use beyond pumping water.
Watt attempted to commercialise his invention, but experienced great financial difficulties until he entered
partnership with Matthew Boulton in 1775. The new firm of Boulton and Watt was eventually highly successful
and Watt became a wealthy man. In his retirement, Watt continued to develop new inventions though none was
as significant as his steam engine work. He died in 1819 aged 83.
He developed the concept of horsepower, and the ST unit of power, the watt, was named after him.
1. Watt improved 1712 Newcomen steam engine to make his own steam engine.

______

2. Watt's invention contributed to the Industrial Revolution in Great Britain.

______

3. He worked as a professor in the University of Glasgow before inventing the steam engines.

______

4. Watt's steam engine consumed more energy but improved the power, efficiency, and cost-effectiveness.


______
5. Watt had no difficulties commercializing his steam engine.

______

6. Watt became rich thanks to the partnership with Mathew Boulton.

______

7. Steam engine is considered Watt's most significant invention.

______

8. The SI unit of power was named after him because he invented it.

______

Exercise 8. Read the text, and then decide whether the statements are true (T) or false (F).
How to Become an Inventor?
Many people think that becoming an inventor is a simple process of three steps: having a bright idea,

researching the market for the idea, and then selling that idea to a large company. It's not that simple, however,
and can often be a time-consuming, difficult process. So let's take a look at what you need to do to become an
inventor.
Every invention starts with an idea. Brainstorm your ideas with colleagues, friends, and family. For any idea
they like, do research to check that your idea is original. Decide if you want to protect or patent your idea from
being copied. Think carefully about this, as you do not want to be an inventor who says, "He wouldn't have been
able to steal my idea if had patented it."
So now you have the idea, what's next? Once you settle on the idea for your invention, study the market you
want to sell it to. Get to know as much as you can about the customers who will buy your product. Make sure it
will be profitable.
Once you have identified that market for your invention, write a business plan, possibly create a sample of
your product, and then go out and try to sell it. This is a challenging stage because you could meet with a lot of
rejection. Keep going and don't give up. Do not lose sight of your goal - seeing your product used and enjoyed
by millions.
1. Becoming an inventor is a difficult process.

___

2. But it does not take a lot of time.

___

3. You should work with your colleagues, friends, and family to choose the topic for your research.

___

4. Make sure that your idea for research is new and unique.

___

5. You should do the market research for your product before you settle on the idea for your invention. ___
