B Read the text below and try to pronounce the -ed endings of verbs in the simple past tense. Then listen and check whether you are right.
Last weekend, I climbed a mountain with my classmates. We also invited our form teacher to go with us. At about 8 o’clock, we arrived at the foot of the mountain. Then we started climbing. We walked along paths and steps up to the top.
~~~~~~~~~~~~~~
invite sb. to do sth.
表示“邀请某人做某事”。
~~~~~~~~~~~~~
山脚下
When we reached the halfway point up the mountain, we were very tired. We stopped for a short while and then went on. It took us about three hours to get to the top. The view from the top was fantastic! I was very tired when I came back home, but it was worth it.
1 在清辅音后发/t/ 音
当动词原形以清辅音结尾时（不包括在词尾发音的/t/和/d/），其过去式词尾-ed 发音为/t/。清辅音是指发音时声带不振动的辅音，如/p/、/k/、/f/、/s/ 等。如：worked /w kt/，helped /helpt/，walked /w kt/
语音知识：动词过去式词尾-ed 的发音
2 在浊辅音和元音后发/d/ 音
当动词原形以浊辅音或元音结尾时，其过去式词尾-ed 发音为/d/。浊辅音是指发音时声带振动的辅音，如/b/、/ɡ/、/v/、/z/ 等；元音则是发音时声带振动，气流通过口腔而不受阻碍的音，如/e /、/e / 等。如：played/ple d/，lived /l vd/，enjoyed / n'd d/
3 /t/ 或/d/ 结尾后发/ d/ 音
当动词原形以/t/ 或/d/ 结尾时（即/t/ 或/d/ 作为该单词的最后一个发音音节），其过去式词尾-ed 发音为/ d/。如：wanted/'w nt d/，admitted/ d'm t d/，started/'stɑ t d/
掌握动词过去式词尾-ed 的发音规则对于提高英语口语水平至关重要。通过大量的听力和口语练习，可以逐渐熟悉并准确掌握这些发音规则。
