Liaison is the connection between words when one word ends with a consonant and the next begins with a vowel. For example, in the phrase "turn off", the "n" links to the "o" and it sounds like "tur-nof". Stress means that certain syllables or words are spoken more strongly than others. For example, in the word "recycle", the stress is on the second syllable /ˌriːˈsaɪkl/. In a sentence, content words like nouns and verbs are usually stressed, while function words like "the" and "of" are not. Understanding liaison and stress helps us speak more naturally and understand native speakers better. When we read the sentence "I always ride my bike to school", the stressed words are "always", "ride", "bike" and "school". The words "I", "my" and "to" are usually unstressed. 根据短文内容，回答下列问题（每题答案不超过6个单词） 1. What is liaison in spoken English?   2. What does stress mean in a word?   3.
