You can hear IT at the beginning of the word back and bag, in the middle of the words hobby and habit, at the end of the word's job, and at the beginning and end of the word bob. Now you try, listen and repeat after me bag. Bag hobby. Habit job. Bob, okay. For speakers of some languages, IT may be difficult to tell the difference between this voice sound and its voice less partner, the one that you can hear at the beginning of . the word pack. Listen carefully to hear the difference for each example. I will say the word with the voice sound first. Back park. bear, bear. cub, cap. sibel, simple. Could you hear the difference? Now lets look at the difference. What's this? Back pack? Bear, bear, cub. cap. symbol, simple. Look again. Back pack with the . voiceless sound. There's a big puff of air you can see . IT with your hands back pack. Now let's try the words again, listen carefully and . repeat back. 怕。Bar pay cup . cup simply . simple. okay. What are you going to eat? I'll get the Green salad. That's the healthiest food. Vegetables are always good for our bodies. I don't agree. The Green salad only has vegetables. You need more than that to be healthy. So what are you getting? The hamburger that's . junk food is high in fat and salt. That's not true. actually. The hamburger has meet bread and vegetables. It's a complete meal.

Boy brother hamburger布迪。Tea, tomato, water, salt. The . bad food idea, doctor. Welcome to eat well, doctor E, I often hear that we should eat as many fruit and vegetables as possible. Is that right? No, actually, you can only eat fruit and vegetables. It's important to eat other foods too. Okay, got IT. And many people saying that all snacks air unhealthy. Is that true? Not exactly. In fact, it's okay to eat snacks, but don't eat too many. Even chips are fine. great. So I can still enjoy some chips. Last question, some people believe that fat and salt are always bad for us. Is IT true. Well, too much fat and salt is bad, but too little is also dangerous. In fact, we need fat and sold for our bodies to work well. It's all about baLance. This is a voice less concerned. You can hear IT at the beginning of the word tin, in the middle of the word button, at the end of the word get, and at the beginning and end of the word tight. In english, we make this sound with the tongue behind the teeth here. Now let's try listen and repeat after me, tin. button. get. tight. okay. This is a voiced consonant. You can hear IT at the beginning of the word dame, in the middle of the word ladder, at the end of the word odd, and that the beginning and end of the world did in english. We make this sound with a tongue behind the teeth hair. So let's practice, listen and repeat dame later. Odd . did . okay. Now you may find that difficult to hear the difference between this voiceless sound that you can hear at the beginning of the word in, and it's voice less partner that you can hear at the beginning of the word din. Listen carefully to hear the difference for each example. I shall say the word with the voiceless sound. First, tin in to . do town. down, eight, eight. Bed, bed. Did you hear the difference? Perhaps you can also see the difference. What's this tin din, did you notice? Have a puff of air at the beginning of ten makes the paper move. Watch ten din. Now let's practice these examples.
