What kinds of public transportation are there in your area
In my area, the public transportation system mainly includes buses and a metro/subway system. There are extensive bus routes covering the city, and the metro has several lines connecting major districts and hubs. Additionally, you can find taxis and ride-hailing services (like Didi) everywhere. In recent years, shared bikes and e-bikes have also become very popular for short trips.
How often do you use public transportation
I use public transportation quite frequently, usually about 3-4 times a week. I often take the metro or bus for commuting to work or when going downtown to avoid traffic and parking hassles. On weekends, I might use it for shopping or leisure trips. For very short distances, I sometimes opt for shared bikes instead.
Why Ask Questions
Helps you stay focused
Makes reading more interactive
Improves understanding and memory
Encourages deeper thinking
Two Types of Questions
1. Yes-or-No Questions
Example: Did she eat breakfast
Can be answered with “yes” or “no”
Useful for checking facts or details
2. WH- Questions
Examples:
Who did they see
What happened next
When did it occur
Where did they go
Why did she say that
How to Ask Questions as You Read
Step 1: Pause after a paragraph or section
Step 2: Ask yourself a question about what you just read
Step 3: Keep reading to find the answer
Step 4: Check if your question was answered or if new questions come up
Why are wind farms usually built on flat areas
How can you tell if an area will have enough wind for turbines
After breakfast, Hector quickly put on his mask and cape.
Hector pressed a button on Lightning.
The blades that began to pedal.
A covering for the face (e.g., a protective face mask, a costume mask); also a device that hides or shields part of something.
mask
A small round fastener for clothes; a small control (on machines/devices) pressed to operate functions.
button
A flat part pressed with the foot to control a vehicle/machine (e.g., bicycle pedal, car brake pedal).
pedal
Flat, narrow parts (e.g., the leaf-like components of turbines/windmills; the sharp flat part of knives/scissors; the flat part of oars).
blades
Which superhero do you like the best
My favorite superhero is Iron Man (Tony Stark). I admire his combination of brilliant intellect, technological innovation, and underlying sense of responsibility. He uses his resources and mind to solve problems and protect people, showing that a hero's greatest power can be human ingenuity.
What kind of superhero would you like to be
If I could be a superhero, I would like to be one focused on knowledge and information—perhaps called "The Analyst." My power would be to instantly process vast amounts of data, identify patterns, predict crises (like natural disasters or resource shortages), and provide the precise knowledge needed to prevent them. The goal would be to solve problems before they require a physical battle.
What do you think a superhero would do to save energy
Iron Man would upgrade his Arc Reactor and suit designs to be even more energy-efficient, and likely develop clean energy technology for cities.
Superman or The Flash could use their super-speed to manually spin turbines, generating massive amounts of wind or kinetic energy in a pinch.
A hero like Swamp Thing or Storm might help grow forests rapidly or optimize weather patterns to support natural energy sources and reduce fossil fuel dependence.
Any hero would likely use their public influence to educate people about conservation, promote renewable energy sources, and fight villains who pollute or exploit Earth's resources.
Hector pressed a button on Lightning. Bang! Wham! Lighting was now a helicopter! He
connected a cable from Lightning to the ambulance. Hector jumped on the bike and began to pedal. The blades that once held an umbrella together were spinning up in the air. The helicopter went high into the sky, carrying the ambulance with it. As they went over the cars, Hector shouted to the people below.
Carpools reduce traffic jams and save fossil fuels! You can also take the train or the subway!
What I liked about the story:
I really enjoyed how creative and imaginative Hector is. The idea that a nine-year-old boy can be an “energy saver” superhero is fun and inspiring. I also liked how the story encourages recycling and creative reuse—like making his cape from old curtains and his bike pedals from potato mashers. The part where he gives practical advice about carpooling, public transport, and solar panels teaches good environmental lessons in a simple way.
Cultural Centre
Solar panels are everywhere. They are not only used to heat water and produce electricity for our homes. Solar panels are used to light emergency road signs, parking lots, and call boxes. Solar garbage cans use solar energy to compact the trash, so more will fit in the can. And it is a tiny photovoltaic cell, like a solar panel, that is used to power our portable calculators. All these objects need is a little sunlight to work.
Then there are some unusual uses of solar panels. There s a dragon-shaped stadium in Taiwan that generates 100% of its electricity from solar panels along the top that look like dragon scales. A solar-powered plane recently completed its first trip from San Francisco, California to New York in the United States. And people are
experimenting with solar-powered sailboats. New uses for solar energy are being made all the time.
What I disliked about the story:
Some parts felt a little too unbelievable, even for a children’s story. For example, his bicycle suddenly turns into a helicopter and lifts an ambulance—that’s pretty wild! Also, the solutions sometimes seem too quick and easy, which might give the idea that solving real-world energy problems doesn’t require much effort.
Funny scenes:
The funniest scene was when Hector’s bicycle transformed into a helicopter using parts from an umbrella. The image of a boy pedaling a flying bike while carrying an ambulance is hilarious and charming. Also, the idea that he wears a superhero costume made from his uncle’s old curtains is very cute and funny—it shows his playful, inventive spirit.

Grammar

a. a lot of /lots of means a big amount
b. a little/ a few means a small amount
Core Concept
Quantifiers are words that express quantity. They tell us how much (uncountable) or how many (countable) of something. The choice depends on whether the noun is countable or uncountable.
Usage & Rules
Quantifier Used With Meaning Example
A little Uncountable nouns (e.g., energy, water, time) A small amount Hector uses a little energy.
A few Countable nouns (plural) (e.g., cars, books, people) A small number There were only a few cars on the road.
A lot of / Lots of Both countable & uncountable nouns A large amount/number Mr. Big uses a lot of energy.
There were lots of cars in the traffic jam.
Important Notes
A little and a few have a positive meaning—they mean “some, but not much/many.”
Little (without “a”) and few (without “a”) have a negative meaning—almost none.
A lot of and lots of are informal and interchangeable. “Lots of” is more common in spoken English.
