以下3個問題希望大家一起幫忙我回答~?

1.Please identify and describe 4-5 features in your spoken English which you feel are (or were, if you have since eliminated the feature[s]) markers of a non-native accent—what these features are, and how they differ from natively-spoken American English.

2. The words matter and madder, and waiting and wading, are pronounced identically in American English. What is
the name of the process which affects both t and d here. Also, please give in square brackets [ ] a phonetic symbol
for the single sound which is used in these examples.

3. When speakers of certain languages pronounce, in their English, w as [v]—as in, for example, “vonderful,
Vednesday, Visconsin”, etc.—what are they doing? That is, describe the phonetic differences between [w] and [v].
Then, give the name for the phenomenon whereby some of these same speakers say “willage” for village,
“wictory” for victory, etc.
