My smartphone is an essential part of my daily routine. I mostly use it for communication, texting friends and family, and making calls throughout the day. It’s also my main tool for accessing information, whether it’s checking the weather, reading news, or finding directions. I probably use it dozens of times an hour for various quick tasks.

I believe smartphones will evolve dramatically in the future. Instead of handheld devices, they might transform into more integrated technologies like smart glasses or even subtle implants. The focus will shift towards seamless interaction and augmented reality, making our digital and physical worlds blend even more effortlessly. Their form may change, but their central role in our lives will undoubtedly remain.

Bạn ơi, mình chưa rõ câu hỏi là gì nhé!

Here is a sample biography of a famous person written in about 150 words, following the suggested structure and tips:

Albert Einstein was born in 1879 in Germany. He is best known for his theory of relativity, which changed the way we understand space and time. When he was a child, Einstein showed great curiosity and love for mathematics and physics. At the age of 26, he published his special theory of relativity, which brought him international fame. Later, he developed the general theory of relativity, which explained gravity in a new way.

One interesting fact about Einstein is that he did not speak fluently until he was four years old, but he became one of the greatest scientists in history. Besides his scientific achievements, he was also a passionate advocate for peace and civil rights.

Today, Einstein’s work still influences modern physics and technology. I admire him because he was not only intelligent but also humble and kind. His life story inspires me to never give up on learning and to always be curious about the world.
