IELTS Listening Practice Hybrid Cars
IELTS Listening Practice Hybrid Cars
About this activity
- This activity is labeled round table by Dr. Hariri, the creator and administrator of LELB Society.
- This activity is on the premise of Flipped Learning, according to which the students watch a video before the class, carry out research into the selected theme, and prepare themselves for an informed discussion in the class.
- This activity is on the basis of both synchronous and asynchronous computer-mediated communication (CMC), according to which the students are also encouraged to be active even before the class.
- In this flipped classroom activity, the students are encouraged to utilize the comment form at the bottom of the post to to exchange their questions, findings, and experiences with each other. Later on, we will discuss the asynchronous activities in the class. In a few words, “let’s learn from each other.”
About the Video Files
- The video files are meticulously selected among the most prominent academicians, lecturers, and scientists based on Google Scholar.
- We might refer to the exact elapsed time ⌛ of the video files to pinpoint specific statements, messages, etc.
Writing Activity
- You should adopt a formal register in your written contributions in the comment form.
- To give an answer to a question or comment, use the Reply button.
- In our written activities, we can practice negotiation of meaning (sharing our findings with regard to the selected themes) and negotiation of form (performing peer-reviewed error correction).
- Put a number before your questions in the comment form successively to refer to them more easily in the class.
- Your questions should be unique and not previously raised by your classmates in the comment form.
Expectations
- You should take equal turns in speaking. The maximum amount of time you can have is 60 seconds.
- This is a fully organized activity; consequently, all your contributions, including comments, replies, and verbal opinions, must be with direct reference to the assigned topic and its corresponding video. Any irrelevant contribution is strongly frowned upon.
- You will be stopped if your speech appears to be irrelevant or not supported by evidence.
- Students leaving comments below will be given priority over others in our informed conversations.
Instructions for the IELTS Listening Part
In this part of your exam, you will be given some instructions as the following:
- Do not open your question paper until you are told to do so.
- Write your name and your candidate number on the specified space on top of this page.
- Listen closely to the instructions for each part of the paper.
- Write your answers to the questions on the questions paper while you are listening.
- At the end of the test, you will have an extra 10 minutes to transfer your answers to a separate answer sheet. Use a pencil to copy the answers.
Section 1
In this section, you will listen to a conversation between two speakers on an everyday and comment topic, such as organizing events, arranging a trip, talking about the weather, etc. You are supposed to listen closely to get specific factual information.
Section 2
This is a monologue on a general topic, such as public events. Again, you are supposed to listen closely to acquire specific factual information.
Section 3
In this section, you will listen to a discussion between 2 or 4 speakers on an academic topic, such as assignments, taking courses, attending seminars, etc. While focusing on specific factual information, you should also pay attention to the speakers’ attitudes and opinions.
Section 4
In this section, you will listen to a lecture (monologue) on an academic topic. You should focus on specific factual information as well as the main ideas. Also you should pay attention to the speaker’s attitudes and opinions.
You will have around 30 seconds before the test starts to see what kinds of information will be required (for instance, names, dates, times, money, etc.)
Hybrid cars
Hybrid cars are vehicles that utilize both an internal combustion engine and an electric motor to provide power. This combination allows hybrid cars to significantly improve fuel efficiency and reduce emissions compared to traditional gasoline-powered cars. The electric motor in a hybrid car can operate independently at low speeds, typically in city driving, while the gasoline engine kicks in for higher speeds and more demanding driving conditions. Regenerative braking is a key feature of hybrids, capturing energy usually lost during braking and storing it in the battery for later use. These vehicles offer a practical solution for those looking to reduce their environmental impact and fuel costs without completely transitioning to all-electric cars.
7. What are the design techniques of hybrid cars in order to run at the maximum efficiency?
Hybrid cars employ several design techniques to achieve maximum efficiency:
1. Regenerative Braking: This system captures energy usually lost during braking and stores it in the battery for later use.
2. Aerodynamic Design: Hybrids are often designed with sleek, smooth shapes to reduce wind resistance and improve fuel efficiency at higher speeds.
3. Low Weight: Using lightweight materials helps reduce the overall weight of the vehicle, requiring less energy to move.
4. Energy Management Systems: Advanced systems manage the flow of energy between the electric motor and the combustion engine, optimizing performance and efficiency.
5. Optimization Algorithms: These algorithms help in fine-tuning the vehicle’s performance under various driving conditions.
6. How long have hybrid cars been working on Canada’s roads?
Hybrid cars have been on Canada’s roads for over two decades. The first hybrid vehicle introduced in North America was the Honda Insight, which debuted in December 1999. Since then, hybrid technology has become increasingly popular, with many models from various manufacturers, including Toyota’s Prius, which has been available in Canada since 2000. Over 200,000 hybrid vehicles have been sold in Canada since 2000.
5. Explain the mechanism of regenerative braking.
4. How can hybrid cars’ batteries last for the entire lifespan of these vehicles?
3. What is the meaning of “The Best of Both Worlds”?
“The Best of Both Worlds” refers to a situation where someone can enjoy the advantages or benefits of two different, often contrasting, things at the same time. For example, having a hybrid car offers the best of both worlds by combining the fuel efficiency of an electric vehicle with the longer range and convenience of a gasoline engine. It’s like having the ideal mix of two desirable qualities, without having to compromise on either.
2. What are the jobs of the internal combustion engine in hybrid cars?
In hybrid cars, the internal combustion engine (ICE) performs several important functions:
1. Primary Power Source: The ICE provides the main source of power for the vehicle, especially at higher speeds and during demanding driving conditions, such as highway driving or accelerating quickly.
2. Battery Charging: The ICE can also act as a generator to recharge the vehicle’s battery pack, especially when the charge level is low. This allows the electric motor to be used more efficiently and extends the overall range of the vehicle.
3. Boosting Performance: In some hybrid systems, the ICE works in tandem with the electric motor to provide additional power during acceleration or when climbing steep inclines, ensuring smooth and powerful performance.
4. Maintaining Efficiency: By switching between the electric motor and the ICE as needed, hybrid cars optimize fuel efficiency and reduce emissions. The ICE can turn off when not needed, such as during idling or low-speed driving, relying on the electric motor instead.
1. What is the essential idea of hybrid vehicles?
The essential idea of hybrid vehicles is to combine the strengths of both internal combustion engines and electric motors to create a more efficient, environmentally friendly mode of transportation. By integrating these two power sources, hybrid vehicles can optimize fuel consumption, reduce emissions, and improve overall performance.
