Think about the following questions and choose one or two to answer. 1.Suppose you are going to introduce a friend of yours to your classmates, what aspects of this person will you choose to include in your description? 2.The name of Albert Einstein is known to every one of us. How much can you tell about him off-hand? How much do you know about him as a great scientist and as a man?

1. If I were introducing a friend to my classmates, I would choose to include aspects of their personality, interests, and achievements. I would highlight their positive qualities such as being friendly, kind, and approachable. I would also mention their hobbies or passions, such as playing a musical instrument or participating in a sports team. Additionally, I would mention any noteworthy achievements or talents they have, such as winning an academic award or volunteering for a charitable cause. By including these aspects, I would aim to provide a well-rounded and positive introduction to my friend.

2. Albert Einstein is widely known as one of the greatest scientists in history. Off-hand, I can recall that he developed the theory of relativity, specifically the equation E=mc². This equation revolutionized our understanding of energy, mass, and the relationship between matter and energy. Einstein also won the Nobel Prize in Physics in 1921 for his explanation of the photoelectric effect.

As a man, I know that Einstein was born in 1879 in Germany and later became a naturalized citizen of Switzerland and the United States. He was known for his iconic wild hair and mustache. Einstein was a pacifist and an advocate for civil rights, using his platform to speak out against war and discrimination. He was also an avid violinist and enjoyed playing music in his free time. Overall, Einstein's contributions to science and his unique personality have made him an enduring figure in history.

1. Yes, I have heard of the English proverb "Hit the nail on the head." It means to accurately or precisely address or identify a problem or issue. It implies that someone has made a direct and accurate statement or observation without any ambiguity.

2. No, I do not believe that one's lexical proficiency can be correctly assessed solely based on the number of words they possess. While having a large vocabulary is undoubtedly beneficial in mastering a language, it is not the sole indicator of someone's language proficiency. Lexical proficiency also involves understanding and using words in context, knowing their appropriate usage, and having a good grasp of idiomatic expressions, collocations, and phrasal verbs. Additionally, language proficiency encompasses other aspects such as grammar, pronunciation, fluency, and comprehension. Therefore, assessing someone's language skills based solely on the number of words they know would be an oversimplification and not an accurate representation of their overall proficiency.
