III. Further reading

   Animated films have been a part of cinema history ever since the first motion pictures were made in the late 1800s.

An animated film is a movie made by using animation instead of live actors, especially a humorous film intended for

children. Animation is a sequence of slightly varying drawings or models that appear to move and change when the sequence is shown.

       Research has shown that children learn more easily from animated films and TV series than they do from traditional ways of learning. The audio and visual cues seen in animation, coupled with creative storytelling, allow children to absorb information more easily than from a teacher in a classroom.

   Children naturally seek out new experiences from an early age. Animation appeals to them because of its wide variety of visual stimulation. The vivid colors and sounds they take in can easily catch their interest. Children will automatically follow the characters they see, even copying their way of speaking and body language.

Making nuclear safer (P6)

 

 

I. Pre-reading

·What is a nuclear power plant?

       A nuclear power plant is a thermal power plant in which a nuclear reactor is used to generate large amounts of heat. This heat is used to generate steam (directly or via steam generator) that drives a steam turbine connected to a generator that produces electricity. Steam turbines are a common feature of all thermal power plants.

 

·How does nuclear power work?

       Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Fission takes place inside the reactor of a nuclear power plant.

B. The core equipment that Hualong One uses comes from other countries.

C. China leads the world in third-generation nuclear technology.

D. The installed capacity of Hualong One has been increased.

III. Further reading

The diagram below shows how a nuclear power plant creates power.

 

 

Nuclear Power in America, How It Works,

Pros, Cons, and Its Impact

Is nuclear power the answer to climate change?

 

   Only 4.4 percent of the world's energy is produced by nuclear power plants. But for many countries, nuclear power's benefits outweigh its risks.

* The United States ranks highest in nuclear energy production.

* Nuclear power plants don’t emit greenhouse gases and are not easily destroyed by natural disasters. They provide many jobs and have low operating costs.

* Accidents can be catastrophic and waste disposal is costly.

 

  Advantages

  Nuclear power plants don't emit any greenhouse gases, unlike coal and natural gas plants. As a result, they don't contribute to climate change. This benefit is becoming more attractive as the world seeks to reduce global warming.

  Nuclear power plants are also more resilient during natural disasters. For example, hurricanes can destroy solar and wind farms. They are less likely to damage the reinforced buildings that house nuclear plants.

  Nuclear plants create more jobs than other forms of energy. They create 0.5 jobs for every megawatt hour of electricity produced. This is in comparison to 0.19 jobs in coal, 0.05 jobs in gas-fired plants, and 0.05 in wind power. The only other power source that creates more jobs/mWh is solar photovoltaic. This source generates 1.06 jobs/mWh.

 

IV. Post reading

Advantages

*Don't emit greenhouse gases

*Resilient during natural disasters

*Job intensive

*Low operating costs

*Fuel efficient

Debate:

Are you for or against nuclear power plants?

 

State your reasons!

 

 

Disadvantages

*Accidents can emit radioactive materials

*No good solution for disposal of nuclear waste

*Not a renewable fuel source
