Fish, cooked or raw, is an important part of a well-balanced diet. It's high in protein and nutrients and low in fat. Eating fish the recommended two or three times a week is a goal worth pursuing.
Good for the heart
Fish contains lots of what we nonscientific people call omega-3 fatty acids. These acids have been shown to help prevent heart disease, lower blood pressure and reduce the risk of strokes. Researchers suggest that these benefits of eating fish far outweigh the risk of getting sick from a contaminated fish.
Good for the brain
Ongoing studies find that omega-3 fatty acids work magic on the brain too. Pregnant? Go out and eat fish! One study tracked a group of expectant mothers who ate more than 340 grams of fish per week. It turns out they gave birth to children who (later) scored really high on their IQ tests.
Don't give up on fish!
Let's face it: There are contaminants in most everything we eat, especially chicken, pork and beef. The chance of getting sick from eating chicken is 1 in 25,000; for fish, the odds drop to 1 in 2,000,000. So, don't write fish off. Just be wise in choosing fish that is safe and healthy.

    鱼肉，熟的也好，生的也罢，都是均衡饮食的重要元素。它富含蛋白质等营养素，而且脂肪含量很低。你可以按照专家建议，每周吃两、三次鱼，这麽做很值得。
对心脏有益
    鱼肉富含我们这些非科学专业人士所谓的Ω3多元不饱合脂肪酸。这种脂肪酸经证实有助预防心脏病、降低血压及罹患中风的风险。研究人员指出，就吃鱼的种种好处来看，吃到受污染的鱼而生病的风险其实不算什麽。
对大脑有益
    许多目前仍在进行的研究发现Ω3多元不饱合脂肪酸对大脑也有神奇的益处。你有喜了？吃鱼吧！一份研究追踪一群每周食用三百四十克以上鱼肉的孕妇，结果她们所生的孩子（後来）智力测验的成绩很高。
别对鱼敬而远之！
    面对事实吧。我们吃的每样东西几乎都含污染物，特别是鸡肉、猪肉和牛肉。吃鸡肉生病的机率是两万五千分之一；吃鱼染病机率则低到两百万分之一。所以，别因噎废食，什麽鱼都不吃。挑鱼的时候要留意，挑一条吃来安全又健康的鱼吧。

Teaching Topic: Hook Idioms 教學主題： 和 Hook 相關 的片語
to be hooked on：着迷或沉迷于某样东西，如He is hooked on television.他沉迷于电视
hook, line and sinker：完全接受，照单全收，这个片语常常用来形容上当的人
to be off the hook：脱离困境，不再需要负责

---Welcome to the Chat Room. I'm Ken.
---And I'm Vickie. And today we begin a new lesson entitled Hooked on Fish.
---Hooked on fish. So we're talking about fishing, right?
---Well, actually no, Ken. The lesson is about whether or not we should eat fish.
---But don't we use a hook to catch a fish?
---Ah, I see where you get the idea. Yes, we use a fish hook when we fish. But the title of our lesson is actually an idiom. To be hooked on something means to be attracted or even addicted to something. For example, if someone really enjoys cooking, we can say: The person is really hooked on cooking.
---I see. 今天的题目Hooked on Fish好像是跟钓鱼有关，因为hook可以是鱼钩，其实to be hooked on这个片语，表示着迷或沉迷于某样东西，比如说He is hooked on television.他沉迷于电视。Are there any other idioms that use the word hook?
---Sure. Here's one that comes from fishing: hook, line and sinker.
---hook, line and sinker. Well, I know what a hook and a line is. But what's a sinker?
---Well, a sinker is a weight you use for sinking fishing lines. So if a fish swallows not only the hook but the sinker and the entire fishing line between the two of them, then the fish has eaten the whole thing. So if someone swallows something hook, line and sinker, they accept it completely without reservation. We often use this when someone falls for a joke or a scam.
---来学一个片语hook, line and sinker，hook是鱼钩，line是钓鱼线，sinker是钓鱼线上的铅垂，我们可以想象一个人如果想一条鱼一样不止是吞下了鱼饵而且把line和sinker全都吞下去，意思就是他完全接受，照单全收，这个片语常常用来形容上当的人，如果你接到诈骗集团的电话，要你汇款到某一个账户，你立即就去做了，你就是swallow hte hook, line and sinker.What about being off the hook? What does that mean?
---Well, that's a common idiom actually. If you're off the hook, you're out of trouble and no longer responsible for something. Your mom may have asked you to do the dishes. But then I did them for you. I can say to you: I did the dishes so you're off the hook.
---这是个很实用的片语to be off the hook意思是脱离困境，不再需要负责，你原本该做的事别人帮你做了，你就是off the hook。
---Well, it's time for us to take a break. Don't go away. Studio Classroom will be right back.

CON
Contaminated!
Today, sadly, fish swim around in polluted waters. Over time, contaminants collect in the tissues of the fish so that later, when we eat the fish, we eat the pollution. The most infamous fish-transmitted toxin is mercury, and it's extremely poisonous. Of course, adult fish-eaters are at risk, but developing fetuses and small children are especially vulnerable.
Sashimi lovers beware
Unfortunately, cooking fish can't remove mercury, but it can kill worms, like the tiny, parasitic worms Anisakis simplex. However, if an infected fish is consumed raw, then the living worms are transferred to your body and you become the host to much unpleasantness. In many countries fish used for sashimi is frozen to kill the worms. But still, about one out of 10 people have an allergic reaction to the dead worms' carcasses.
Bugs
Be careful as many different kinds of bacteria can also be found in fish. Some of them like Salmonella are destroyed through cooking, but others like Listeria remain unaffected by a hot frying pan.
Looking for a safer way to get the health benefits of omega-3 fatty acids? Try nutritional supplements. These fatty acids are also found in nuts, soybeans and green, leafy vegetables.
Now, what's your viewpoint?

    有污染！遗憾的是，今天的鱼都住在饱受污染的水域。长久下来，污染物会堆积在鱼体的组织中，当我们吃鱼的时候，我们连带也把污染物吃下肚。在所有透过鱼传播的毒素中，最恶名昭彰的莫过於汞，汞含有剧毒。当然，吃鱼的成人有危险，但发育中的胎儿和幼童更容易受害。
爱吃生鱼片的饕客小心了
    遗憾的是，就算把鱼煮熟也无法清除鱼体内的汞，不过煮熟确实可以杀掉虫子，如微小的寄生虫海兽胃线虫。然而，如果你生吃受感染的鱼，这些活虫会转移到你的体内，你便会成为宿主而备感不适。在许多国家，要用来做生鱼片的鱼会先冷冻，以把虫子杀死。尽管如此，每十人仍有一人会对虫子的屍体产生过敏反应。
虫子
    由於鱼本身也带有各种细菌，因此要特别当心。有些细菌如沙门氏菌在烹煮过程中便能消灭，但像是李氏杆菌等其他菌种，就算高温煎煮炒炸也不受影响。
    想要安全无虞地享受Ω3多元不饱合脂肪酸的益处吗？不妨试试营养补充品。坚果、大豆和绿色叶菜类蔬菜也含有这种脂肪酸。
    那你的看法呢？

Teaching Topic: Sad Fish? 教學主題： 悲傷的魚？

---Welcome to the Chat Room. I'm Ken.
---And I'm Vickie. Well, today we continue with our lesson Hooked on Fish.
---That's a very interesting lesson, Vickie. You know I didn't know that fish had emotions.
---Fish having emotions? Where did you get that idea?
---From the lesson. Look, here, it says: Today, sadly, fish swim around in polluted waters. It's telling us that fish feel sad because they have to swim in polluted waters.
---Ahh. Be careful, Ken. Notice it's not saying fish swim sadly in polluted waters. The adverb "sadly" is at the beginning of the sentence, followed by a comma. So it's not talking about how the fish feel.
---So who is feeling sad?
---Us, and people in general. The sentence is saying the fact that fish swim around in polluted waters is a sad thing for us to see.
---Hmm, can you give some other examples?
---Sure. I might say: Fortunately, the sun came out. I'm saying that it's fortunate for us that the sun came out. Maybe we were planning to have a picnic. Or if I say: Surprisingly, the sun came out. I'm simply saying that we were surprised that the sun came out.
---Because you didn't expect it to come out.
---That's right. You've got it.
---注意课文中的这句话Today, sadly, fish swim around in polluted waters.注意sadly这个副词，并不是修饰swim注意这里并不是说鱼很忧伤地在水中游，当一个副词单独放在句首，这个副词是运用在一般人，这句话是说看到鱼儿在污染的河中游泳，这是令人遗憾的，很悲哀的一件事。
---And no need to feel sad, friends, because it's time for a break. We'll be right back. Don't go away
