1a. "She looked up in surprise." → This is idiomatic and more natural. "In surprise" means the manner in which she looked up (like "in anger" or "in confusion"). 1b. "She looked up with surprise." → This is grammatically correct but slightly less idiomatic. It’s still understandable and acceptable, but "in surprise" is more common and fluid in native usage. Meaning: Both mean the same, but 1a sounds more natural. --- 2a vs. 2b 2a. "They couldn't conceal their surprise at seeing us together." → This is correct and natural. The phrase "at seeing us together" explains the cause of their surprise. 2b. "They couldn't conceal their surprise seeing us together." → Grammatically possible but slightly awkward. It sounds like “surprise seeing us together” is one concept, which can feel less precise. Meaning: Both express a similar idea, but 2a is clearer and better structured.

"I had an amazing weekend hiking on a snowy mountain. It took nearly two hours by car from Chengdu to the foot of the mountain. We spent four hours climbing to the top of the mountain and more than two hours walking down. The landscape was breathtaking, but the trail was quite challenging. I saw a man pushing a bicycle to the top of the mountain. It was incredible. Some people even made hotpot at the summit!"

wird die Präposition „für“ verwendet, weil sie das Ziel oder den Zweck der Handlung – werben – angibt. --- Erklärung: 1. „Werben für etwas“ Im Deutschen verlangt das Verb „werben“ die Präposition „für“, wenn es sich auf das beworbene Objekt bezieht. Beispiel: Die Firma wirbt für ein Produkt. „Für“ zeigt hier an, was beworben oder angepriesen wird. 2. Funktion im Satz „Für Produkte oder Firmen“ ist das Präpositionalobjekt zu „geworben“. Es beantwortet die Frage: „Wofür wird geworben?“ Ohne die Präposition „für“ könnte die Aussage nicht klar gemacht werden, da der Bezug zum Ziel der Werbung fehlen würde.

"Today, for the first time in a while, I went for a walk."

A relative sentence (or relative clause) provides extra information about a noun in the main clause and is introduced by a relative pronoun like who, which, that, or whose. It can be defining (essential to the meaning) or non-defining (extra information). Examples: 1. Defining relative clause: "The man who opened the door is my neighbor." The relative clause "who opened the door" defines which man you're talking about.
