How to pronounce concave and convex

The word concave-convex comes from the Japanese word "ぉぅとつ", which is a common word in Chinese and pronounced as "āotū". Below I will introduce the meaning and pronunciation of bump in detail.

1. The meaning of bump

Bump is an adjective used to describe the shape or texture of an object surface. Its basic meaning is that it has been deformed such as bending and bulging, and its surface is uneven, sometimes it can also indicate that it has complex levels or colorful characteristics. For example: rugged mountain roads, rugged sculptures, rugged music, rugged muscle textures, etc.

2. Pronunciation method

It should be noted that the second syllable of concave-convex is "tū" instead of "tú". The difference between the two sounds here is that the pronunciation of the former "u" is relatively clear, while that of the latter is relatively vague. Therefore, it is necessary to pay attention to linking the tone of "tū" with the tone of "āo" when pronouncing, which is similar to the Chinese character "convex" and the pronunciation of concave and convex is quite similar.

specifically, the first thing to pay attention to is the pronunciation of the word "concave". In Chinese, its pinyin is "āo", and its pronunciation is similar to that of the word "ao". It should be noted here that the lips should protrude slightly when pronouncing, inhale when pronouncing, and then close the lips quickly.

Then there is the pronunciation of the word "convex". Its pinyin is "tū", which is the same as the Chinese surname "tu". When you pronounce it, you need to raise your tongue slightly, so that the tongue surface is close to the palate, and then relax quickly. Finally, we can get the correct pronunciation of the word "āo tū" by connecting the pinyin of the two words.

Make sentences as follows:

2. Bow first sets an example to lead the masses to join the ranks of Aowa * * * to enjoy renting a car, share the idle resources of the car with friends around them, and make more like-minded friends while doing our best for environmental protection.
