小白老师说：大家好，这是2020 新大纲样卷的听力 Section A 部分的录音文字稿。这部分有五则对话，英式发音，语速中等。
M: I'm always seeing in the news these days that we're eating too much sugar. And one important factor is that sugars are sometimes hidden in processed foods.
W: Do you check the information on the back of food packets, Rob?
M: Yes, I do. But it can be very confusing. There's so much information.
W: Some food products have colour coding on the packaging to help you understand the information. Red for high levels of sugar, salt or fat, orange for medium, and green for low.
M: That sounds helpful.
W: But one problem we see in nutrition is sort of this focusing on any individual foods. Sugar is demonised. People link it to drugs. And I think this is the wrong way forward.
Questions number 1~3 are based on the conversation you've just heard.
Question Number 1: What is mainly discussed in the conversation?
Question Number 2: Which colour is mentioned to represent low levels of sugar?
Question Number 3: According to the woman, what is the problem with people's attitude towards sugar?
W: How's your mood today? Feeling happy?
M: Very happy. I've just had lunch.
W: That's good! I was doing some research about feeling angry when you are hungry.
M: Oh, how is that?
W: When we are hungry, the level of sugar in our blood is lower. As the blood sugars drop, this causes an increase in particular hormones-hormones that the body uses to prepare us to either fight or run away from a dangerous situation. And those have an impact on our brain. The neuropetides that trigger for hunger are the same ones that trigger for anger.
M: So when we are hungry, the same emotions can run through us. We can be angry and make poor decisions. And that is hunger.
Questions number 4~6 are based on the conversation you've just heard.
Question number 4: What are the two speakers talking about?
Question number 5: According to the conversation, what will happen when we are hungry?
Question number 6: What can we say about anger and hunger according to the conversation?
W: I need information on purchasing health insurance.
M: Is this the first time you have had health insurance?
M: You have a choice of HMO or PPO. Do you understand the difference?
W: I am not sure what those are.
M: An HMO is a little cheaper, but you have limited choices of which doctor you choose.
W: Are the payments the same for a PPO and HMO?
M: By going to the providers on the HMO list, you can save money in out-of-pocket expenses.
W: Can you give me a comparison between a PPO and an HMO?
M: We can mail you a questionnaire and when we have all of your information, we will mail you a quote.
Questions number 7~9 are based on the conversation you've just heard.
Question number 7: What is mainly talked about in the conversation?
Question number 8: What can we learn about an HMO?
Question number 9: What is the advantage of an HMO over a PPO?
W: Don't crack your knuckles! You'll end up with arthritis when you're older.
M: I don't know why I do it. It just feels nice.
W: Now we can use MRI imaging to see what is actually happening inside the joint when someone cracks their knuckles.
M: Then what is happening?
W: Well, when you crack your knuckles, it stretches the space around the joint and surrounding fluid and causes the formation of bubbles. Now when you stretch the joint far enough, these bubbles burst, producing the 'pop' sound.
M: Is there any damage to the joint?
W: When the bones of the joint are pulled apart, and there'll be a little bit of fluid in between, which can damage the surfaces of the joints.
Questions number 10~12 are based on the conversation you've just heard.
Question number 10: What is the conversation mainly about?
Question number 11: What happens when you stretch the joint far enough?
Question number 12: What could cause the damage to the surfaces of the joints?
M: Can you stay focused for the full six minutes? Sounds easy? Maybe not, because today we're talking about our attention spans: are they shrinking?
W: Yes, a report said the average human attention span has fallen to just eight seconds.
M: Can that be true? Goldfish reportedly have an attention span of nine seconds. Human attention span is now shorter than that of a goldfish?
W: Yes. Smartphones, the Internet, social media-these all certainly do take up a lot of our attention.
M: OK, but some psychologists said for someone distracted by their smartphone or wanting to quickly Google something, it doesn't mean that they don't have the ability to control and sustain their attention when they carry out another task.
Questions number 13~15 are based on the conversation you've just heard.
Question number 13: What is the main topic of the conversation?
Question number 14: What can we learn about the average human attention span when compared with a goldfish?
Question number 15: What did the psychologists say about some smartphone users?
