### **【学习材料】每日英语精选对话 (Part 1/2)**


**完整对话原文 (仅英文，带时间戳，紧凑 Markdown 格式)**


**(0:12) 主播A:** Welcome to your Daily Listen!

**(0:14) 主播B:** We're your AI hosts, bringing you stories from across the web.

**(0:17) 主播A:** We've got a lot of stories to tell, so let's get started.

**(0:20) 主播B:** Let's start with the first story.


---


**(0:22) 主播A:** Our first story takes us to Europe, where we have some interesting news from Tesla.

**(0:27) 主播B:** Yeah, the new Model Y Performance just dropped there, right?

**(0:29) 主播A:** Exactly. And uh it sounds pretty powerful. They're saying 460 horsepower.

**(0:34) 主播B:** Yeah, that's quite a jump. It's the dual motor setup, obviously.

**(0:37) 主播A:** Right, dual motor. And fast, 0 to 100 kilometers per hour in what, three and a half seconds?

**(0:43) 主播B:** Just 3.5 seconds, yeah. And uh top speed is apparently 250 kph.

**(0:48) 主播A:** Wow, okay. So definitely living up to the performance name.

**(0:52) 主播B:** Absolutely. And it's not just straight-line speed. They've included um adaptive suspension.

**(0:57) 主播A:** Oh nice. So it should handle well too, not just accelerate like crazy.

**(1:01) 主播B:** That's the idea. Better handling for a high-performance SUV. Makes sense.

**(1:05) 主播A:** And it gets some visual upgrades too.

**(1:07) 主播B:** It does. Uh comes with 21-inch wheels. They're calling them Arachnid 2.0.

**(1:10) 主播A:** Arachnid 2.0. Okay. Catchy.

**(1:12) 主播B:** And a carbon fiber spoiler, you know, for that sporty look. Plus heated sport seats inside.

**(1:17) 主播A:** Right, right. Usual performance touches. What about pricing?

**(1:20) 主播B:** Well, it varies a bit by country, naturally. But reports say it starts around uh 62,970 euros in Germany.

**(1:28) 主播A:** 63,000 euros roughly. And range. Still important even for a performance model.

**(1:34) 主播B:** True. They're quoting 580 kilometers.

**(1:37) 主播A:** 580 kilometers. That's uh about 360 miles give or take.

**(1:42) 主播B:** Approximately. But keep in mind that figure is under the WLTP cycle.

**(1:46) 主播A:** Oh, right. WLTP. So real-world might be a bit less, depending how you drive it.

**(1:52) 主播B:** Exactly. Especially if you're, you know, constantly testing that 3.5 second acceleration.

**(1:57) 主播A:** Heh, yeah, probably drains it a bit faster.

**(1:59) 主播B:** Uh-huh. Yeah. But overall, it seems like a pretty potent package they've put together for the European market.

**(2:03) 主播A:** Definitely. A high-power, well-equipped electric SUV option.


---


**(2:08) 主播A:** Our next story takes us to Google's first spam update for 2025.

**(2:14) 主播A:** It started rolling out, what, August 26th?

**(2:16) 主播B:** That's right, yeah, the 26th. And uh reports were saying it was uh scheduled for, you know, a couple of weeks, the usual time frame.

**(2:23) 主播A:** Right, the standard slow burn we expect.

**(2:25) 主播B:** Exactly. But this one, uh, it seemed to hit much faster.

**(2:29) 主播A:** Yeah, I saw a chatter saying major impacts were seen in just like 24 hours. That's pretty quick.

**(2:34) 主播B:** Extremely quick. By August 27th, folks were already seeing pretty significant ranking changes.

**(2:40) 主播A:** Okay, wow. And, you know, experts are pointing out that this kind of immediate widespread effect isn't typical for these spam rollouts. Usually it ramps up.

**(2:48) 主播A:** So not the usual gradual shift then. What are people actually seeing? How are um webmasters and SEOs reacting?

**(2:56) 主播B:** Well, it seems pretty mixed actually, which is interesting.

**(22:58) 主播A:** Mixed how?

**(2:59) 主播B:** Some people are reporting, you know, huge drops their rankings just tanked overnight, essentially.

**(3:03) 主播A:** Ouch. Yeah, that's never good news.

**(3:05) 主播B:** Definitely not. But then, on the flip side, others are reporting big increases.

**(3:10) 主播A:** Oh really, so some sites actually benefited almost immediately.

**(3:14) 主播B:** Apparently so, yeah. It wasn't just negative impact across the board. It seems quite volatile.

**(3:19) 主播A:** Hmm. So massive swings in both directions. That kind of suggests it's maybe targeting something quite specific, doesn't it?

**(3:26) 主播B:** It could do, yeah. That rapid effect, hitting hard and fast, might mean the algorithm had a very clear identifiable pattern it was looking for, perhaps.

**(33:34) 主播A:** Right, and sites either match that negative pattern and dropped, or well, maybe benefited from competitors dropping.

**(3:41) 主播B:** That's one possibility. Or perhaps the update also re-evaluated certain positive signals more strongly. It's a still early days to say for sure.

**(3:50) 主播A:** True. But the key takeaway seems to be the speed and the um the volatility of it all this time around. Quite a dramatic start.

**(3:58) 主播B:** Absolutely. Very different from the slower paced updates we've often seen. This one definitely made an entrance.

**(4:03) 主播A:** It's certainly did. We'll obviously have to keep an eye on how this develops over the coming weeks.


---


**(4:08) 主播A:** Our final story takes us to Li Auto.

**(4:10) 主播A:** We're hearing some news about Bofa Securities.

**(4:13) 主播B:** That's right. According to reports, they've actually downgraded their rating.

**(44:16) 主播A:** Oh. From what to what?

**(4:18) 主播B:** Moved it from buy down to uh neutral.

**(4:22) 主播A:** Okay. And what's the thinking there?

**(4:24) 主播B:** Well, it seems to be a reassessment of, you know, their market position and maybe their future outlook.

**(4:30) 主播A:** Mhm.

**(4:30) 主播B:** Some reports are indicating that Li Auto's second quarter earnings, they actually fell a bit short of expectation.

**(4:36) 主播A:** Ah, okay. And that impacts Q3 too.

**(4:39) 主播B:** Apparently so.

**(4:40) 主播A:** Mhm.

**(4:41) 主播B:** They've also got lower guidance out for the third quarter.

**(4:43) 主播A:** Right. So how much lower are we talking for Q3 revenue and like what's behind this trend? Deliveries down too?

**(4:50) 主播B:** Yeah, the Q3 guidance suggests revenue might actually come in below Q2's numbers, that was around RMB 30.2 billion. And yeah, they're projecting a year-over-year dip in deliveries too.

**(5:00) 主播A:** So competition heating up.

**(5:02) 主播B:** Experts definitely think that's a key factor. The market's getting uh pretty intense.

**(5:07) 主播A:** Yeah, I bet. And wasn't there another firm, Macquarie also weighing in?

**(5:11) 主播B:** Correct. Macquarie, they're actually maintaining an underperform rating.

**(5:15) 主播A:** Underperform. Oof. Why is that?

**(5:18) 主播B:** They seem concerned about uh slowing demand specifically for Li Auto's extended range electric vehicles. Their ERVs.

**(5:26) 主播A:** Ah, slowing demand for those, plus the competition you mentioned.

**(5:29) 主播B:** Exactly. So you put those two together, the slowing EREV demand in this, you know, intensified competition. It really highlights the challenges. Even for, well, for prominent players like Li Auto in this particular segment. It's getting tough out there.

**(5:42) 主播A:** Definitely sounds like some headwinds for them right now.

### **三、学习策略：全方位出击，细致入微**


1. **“慢进快出”发音练习 (Slow-in, Fast-out Pronunciation)**:

* **慢进**: 播放音频时，遇到标注的词汇，刻意放慢语速，清晰地大声跟读其音标。例如，对于 `authentication` (/ɔːˌθɛntɪˈkeɪʃn/)，放慢节奏，确保每个音节都准确发出。

* **快出**: 在确认每个音节发音正确后，尝试用正常语速跟读整个句子，感受连贯性。这有助于您在保证准确性的同时，提升口语的流畅度。


2. **核心概念“滚雪球”式复习 (Snowball Review of Core Concepts)**:

* 本次材料中有很多之前出现过的核心词，例如 `vulnerability`、`malware`、`infrastructure`、`dominance`。

* 每次遇到这些词，除了回顾其基本含义，请您**快速回想它们在之前哪些新闻中出现过，分别代表什么含义**。这会像滚雪球一样，让您对核心概念的理解越来越深。


3. **自创“微情景对话” (Micro-Scenario Dialogue)**:

* 选择一个您觉得感兴趣的子主题（例如“如何应对网络诈骗”或“谷歌在弗吉尼亚的投资”）。

* 尝试想象您正在与人就此主题进行对话，然后运用今天学到的相关词汇和短语进行**自问自答**。这能极大地促进您将新知识转化为口语输出的能力。
