What are the common phonetic phenomena in TOEFL listening?

For many students who are going to take the TOEFL, I don't know how they are preparing. Today, let's learn about the common phonetic phenomena in TOEFL listening with me.

the first kind, which is also the most famous and representative one, is the phenomenon of linking.

The phenomenon of linking is to read the words at the end of consonants and the words at the beginning of vowels, such as night in, which sounds particularly like "nineteen" when linked. This is why continuous reading will bring great trouble to students with poor listening ability. In addition, there is also linking between vowels, and the pronunciation should naturally slide from one vowel to another, without stopping in the middle, and it must be done in one go. For example, the superlative of happy: Happy. Here, the letter I is pronounced [i] and the letter E is pronounced [i], so there are two consecutive [i]. Two [i] are serialized together, and the pronunciation is [j]. Students can experience it for themselves.

second, the phonetic phenomenon is the loss of blasting.

there are six plosives in the English phonetic alphabet, namely | p ||| b ||| t ||| d ||| k ||| g |. For example, the t in sit down is going to explode. |p| in lap top needs to be exploded. The biggest trouble caused by this phonetic phenomenon is "inaudible" and "inaudible". Many times, because of the loss of blasting, some words that candidates originally knew could not be recognized.

Third, there are some differences between American accent and British accent.

Although the frequency of English sounds in TOEFL listening test is not high, many teachers' spoken English is also mixed with English sounds in our primary school, junior high school and even university education. Similarly, there may be differences between English and American sounds in college English textbooks. So it is necessary to summarize these phonetic differences. For example: | in English? | is often pronounced as |a| in American sound, such as hot; |a:| in English is often pronounced as | in American English. |, such as ask. In addition, the most classic feature of bel canto is "Er Hua Yin". Some candidates blindly pursue authentic expression in the oral exam and overuse the children's pronunciation, resulting in many jokes. For example, I've heard someone put a retroflex after China, and the effect is very funny.

the fourth is the language rhythm.

I mentioned a similar situation in the article on the analysis of hard of hearing questions. When a professor speaks with a long tone, it is usually followed by the key points: most of them can be summarized into the following three concepts: 1. Inspire (encourage) students to answer. 2 Ask yourself and answer yourself. 3 indicates emphasis. These three are all important information, so we should focus on taking notes. Language rhythm is equivalent to the rhythm when reading sentences. No matter how short the sentence is, there are priorities. Information that is read slowly is more important than information that is read quickly. In addition, the position of sentence stress is also very important. For example, the stress of I can do it is usually above do, emphasizing that I can do it. But for the negative form of this sentence, I can't do it, the emphasis is on "can't do it", so the stress is on can't. Because can't and do constitute a loss explosion (just mentioned above), this sentence I can't do it sounds almost the same as I can do it. In this way, severity is an important basis for you to judge whether it is positive or negative.
