阅读 A｜Explaining What a Product Does

A product description should help someone imagine a useful activity, rather than simply introduce a collection of impressive technical features.

Our example product is a small learning website for adults who want to practice language skills during a busy day.

There is a short introduction on the home page, and there are several lessons that visitors can explore without creating an account.

Each lesson includes a reading passage, a conversation, a vocabulary list, and a few exercises with clear answers.

The main value is the connection between understanding an expression and using it to complete a familiar task.

For example, a learner can read about changing a page and then practice making the same request in English.

The website does not need a complicated interface to deliver that value, but it does need accurate and accessible content.

We explain the available functions with ordinary verbs such as read, listen, save, review, and practice.

When a visitor understands these actions, it becomes easier to choose a lesson and begin a meaningful learning session.

A good description therefore connects the audience, the activity, and the benefit in language that a new user can understand.

The explanation should remain useful even when the visitor has no technical background.

The website does not need a complicated interface to deliver that value, but it does need accurate and accessible content. 网站无需复杂界面来提供价值，但内容必须准确且易于获取。

We explain the available functions with ordinary verbs such as read, listen, save, review, and practice. 我们用阅读、聆听、保存、复习和练习等普通动词解释功能。

When a visitor understands these actions, it becomes easier to choose a lesson and begin a meaningful learning session. 访客理解这些操作后，更容易选择课程并开始有效学习。

A good description therefore connects the audience, the activity, and the benefit in language that a new user can understand. 好的说明把受众、活动和收益用新用户能懂的语言连接起来。

The explanation should remain useful even when the visitor has no technical background. 即使访客没有技术背景，说明也应有用。

阅读 B｜A Visitor’s First Session

Imagine that a new visitor opens the learning website during a short break and has only fifteen minutes to study.

The visitor does not know our course names, so the first page needs to explain which lesson offers a suitable starting point.

There is a brief goal above each lesson, and a sample sentence shows the kind of expression the visitor will practice.

After choosing a lesson, the visitor reads the English passage and checks the Chinese explanation whenever an unfamiliar expression appears.

A vocabulary section provides a few useful meanings, while the examples show how the same words work in different situations.

The visitor can then move to a short exercise and try to produce a complete sentence without looking at the original.

If an answer is difficult, there is a reference version to compare with the visitor’s own attempt and improve it.

This first session should end with a small achievement, such as describing a project or asking a clear question.

We can evaluate the product by asking whether the visitor understands the next step and finds the material useful.

The number of features matters less than the quality of this ordinary experience, especially when the product is still young.

The visitor can then move to a short exercise and try to produce a complete sentence without looking at the original. 之后访客可以做短练习，不看原文尝试说出完整句子。

If an answer is difficult, there is a reference version to compare with the visitor’s own attempt and improve it. 回答有难度时，可以对照参考答案改进自己的表达。

This first session should end with a small achievement, such as describing a project or asking a clear question. 第一次学习应以小成果结束，比如介绍项目或清楚提问。

We can evaluate the product by asking whether the visitor understands the next step and finds the material useful. 我们可以询问访客是否知道下一步、材料是否有用，以评估产品。

The number of features matters less than the quality of this ordinary experience, especially when the product is still young. 产品处于早期时，日常体验质量比功能数量更重要。

工作对话

Visitor: I have a few minutes to study, but I do not know which lesson to choose or what the website offers. 访客：我有几分钟学习，但不知道选哪课，也不清楚网站提供什么。

Visitor: Do I need to create an account before I can read the passage and look at the vocabulary explanations? 访客：阅读文章和看词汇解释前，需要建账号吗？

Guide: You should be able to introduce a small project and explain your usual working habits in several clear sentences. 引导者：你应该能用几句清晰的话介绍小项目并解释工作习惯。

Visitor: That sounds useful; is there an exercise where I can try to say the same thing about my own project? 访客：听起来有用，有练习让我介绍自己的项目吗？

Guide: Yes, there are questions at the end, and you can compare your answers with reference expressions after trying them yourself. 引导者：有，末尾有问题，自己尝试后可以对照参考表达。

语法精讲与结构拆解

G03-1 冠词与首次提及

There is a short introduction on the home page.

a 引出一个介绍；the home page 特指该网站首页。不能在单数可数名词前无故省略限定词。

对照／迁移：a lesson → the lesson

G03-2 there is / there are

There are several lessons that visitors can explore.

there are 表示存在多个；主语lessons为复数；单个用there is。不是there have。

对照／迁移：There is a passage. / There are exercises.

G03-3 单复数与每一个

Each lesson includes a vocabulary list.

each＋单数名词；includes 用单数。each lesson 不写each lessons。

对照／迁移：Each visitor has a goal.

相关结构补充与易错点

there is/are：存在

说明系统里有什么；不要写 There have a service。

• There are three running containers. 有三个容器正在运行。
• Is there a simpler way? 有没有更简单的方法？

冠词：a/an/the

第一次提到一个可数对象通常用 a/an；双方已知或特指时用 the。a/an 按后续发音选。

• Create a page, then send me the preview link. 创建一个页面，再把预览链接发我。
• We need an API endpoint. 我们需要一个 API 端点。

单复数与主谓一致

this feature is；these features are。all 后根据名词判断。

• Are all the scenarios live? 所有场景都上线了吗？
• Each server has its own configuration. 每台服务器都有自己的配置。
