Task 1:
The given diagram illustrates the process of producing electricity in a hydropower power
station.
Overall, the process has about 7 stages in total, starting with the evaporation of sea water
and ending with the electric power supply through underground cables.
To begin with, heat given off from the sun evaporates the sea water, which forms water
vapor into clouds as we usually see. Then, these clouds cause rain, with an amount of water
stored in a reservoir. A valve of the dam plays a role as controlling water current flowing to
the turbine, as it creates pressure to spin the turbine.
Subsequently, the electricity generated would be transmitted to the powerhouse through
high voltage cables, while the used water would be pumped back to the reservoir for
reusable purpose. Finally, the generator from the transformer station connected with long
underground cables will transport the electricity to households, factories or schools, hospitals
to serve their daily needs.
Task 2:
With the popularity of technology nowadays, cyber-crimes are considered as a pressing
concern in many nations. While some people advocate for the government to strictly control
the Internet to reduce this issue and protect citizens from cyber-crimes. I partially agree with
this perspective. This essay will examine various perspectives on this problem and offer my
viewpoint in subsequent paragraphs.
On the one hand, the authorities should censor the internet due to the stealing of personal
information. As many social media platforms today have low security yet have an enormous
number of users, criminals would easily crack down the wall fire to access users’ private
data. In other words, they could access users' personal information such as bank accounts,
home addresses, or phone numbers for fraud purposes. Therefore, there has been a
dramatic rise of stalking and fraud online, which could lead to serious accidents for people
who get involved. For example: Facebook now is a large and powerful platform, yet its
security is too low as facebook account could easily got hacked, and hackers would steal
personal data or even forge these users to
On the other hand, this issue would not be too strictly controlled to let everyone approach
helpful sources. In some cases, several useful information could be deleted by reports of
other people, which prevent the public from knowing the truth. Some blogs or online
newspapers about political doubt are sometimes blocked down by the authorities, thus
making citizens misunderstand about the current situation, or even raise strikes due to lack
of trust in authorities. Therefore, censoring information suitably and always informing true
news to the public is an appropriate solution for this drawback.
In conclusion, while protecting online users from cybercrimes is necessary for the
government, it is also advisable not to be too harshly censored or delete several pieces of
information to provide news and current affairs for every cybernaut, avoiding raising political
doubt from dwellers. While this issue remains subject to debate, I believe that the
government should have flexible action to not only prevent online crimes, but also transport
the most suitable and detailed knowledge to everyone.
