The current number might be out of date soon.
Listening
Read the listening materials and check your answers.
Ann: Hi Ellie, have you thought about our project on different countries
and people around the world Any ideas so far
Ellie: Of course. I've already written down some questions for the project.
Let’s look up the answers online!
Ann: Sounds good. I’m free to do it now. What questions do you have
Ellie: OK, here's my first question. How many countries are there in the world
Ann: Almost 200 countries.
Ellie: How many people are there in the world
Ann: The number keeps changing. A report from 2022 shows that there are
around 8 billion.
After-Listening
Ellie: Got it. It’s obvious that the world population is still growing.
Ann: Yes, indeed. The United Nations believes the world population will be
larger than 10 billion by 2100.
Ellie: Wow. That’s huge. Where do most people live, then
Ann: Asia is the most populous continent. Almost two-thirds of the world’s
population live in Asia. Currently, the world's three most populous
countries are India, China and the USA.
Ellie: Good. Just curious: which are the most populous cities in the world Ann: Well, according to the latest data, the three most populous cities are
Tokyo in Japan, Delhi in India, and Shanghai in China.
Ellie: Noted. Let’s make sure to include the correct information in our project.
4 　Imagine that you are working on a project about the population of different countries around the world. What methods are you going to use to find the information How will you record and present the information you collect
...
...
Your ideas
To find population information, I'll use these methods:
1. Look up data on trusted websites like the United Nations or World Bank.
2. Check recent books or reports about global population.
To record and present it:
- Write down key numbers (e.g., top 5 most populous countries) in a notebook or Excel sheet.
- Make a simple chart or poster with country names and their populations to show the results clearly.

Speaking
功能词 语境 & 读法 发音解析
a “have a plan” → / /
“buy a book” → / / 弱读，日常交流中简化为 / /，让句子更流畅
an “an umbrella” → / n/ 弱读，替代强读 / n/，避免发音卡顿
the “the new museum” → / /
“The museum” → / / 弱读 / /，遇元音开头单词会变 / i/（如 the umbrella→/ i/，但此对话无此情况 ）
can “Can you come” → /k n/
“we can go” → /k n/
（若想强调 “真的能去”，可强读 /k n/ ） 日常弱读 /k n/，强调时用强读 /k n/
to “to finish” → /t / 弱读 /t /，比强读 /tu / 更自然
have “we have to” → /h v/ （注：此处 have 是实义动词 “有”，一般不弱读；若为助动词如 “I’ve done” 则弱读 / v/ ） 实义动词 “have” 强读 /h v/，助动词时弱读 / v/，需区分语境
Listen and repeat. Pay attention to the words in blue.
May: Do you know the number of students in your class
Ben: Yes, I do. There are 35 students in my class—18 boys and 17 girls. I can remember all their birthdays!

Summary
07
现在完成时（Present Perfect Tense）
结构：have/has + 过去分词
文本例句：I've already written down some questions for the project.（我已经为这个项目写下了一些问题 。）
解析：强调 “write down” 这个动作对现在造成的影响，即问题已记录好，当下可用于项目相关工作，体现过去动作与现在状态的关联 。
there be 句型
结构：There be + 主语 + 地点 / 时间状语
（表示 “某地 / 某时有某物 / 某人” ）
文本例句：There are 35 students in my class—18 boys and 17 girls.（我的班级里有 35 名学生 ——18 个男孩和 17 个女孩 。）
解析：“35 students” 是复数主语，所以用 “There are” ，用于描述存在的人或事物的数量、情况，是英语里表达 “有” 的基础常用句型 。
宾语从句
文本关联例句：
Do you know the number of students in your class
你知道你们班学生的数量吗？ 可拓展为完整宾语从句形式：
Do you know what the number of students in your class is ，“what the number of students in your class is” 为宾语从句，作 know 的宾语 ）
解析：宾语从句就是用一个句子来充当另一个句子的宾语，用于表达更复杂的语义内容，让表达可以传递如 “知晓、认为” 等涉及具体信息的含义 。
一般将来时（Simple Future Tense）
结构：will + 动词原形
文本例句：The United Nations believes the world population will be larger than 10 billion by 2100.
（联合国认为，到 2100 年世界人口将超过 100 亿 。）
解析：用 “will be” 表达对未来（2100 年人口情况 ）的预测，用于描述将来会发生的动作、存在的状态或做出的预测、计划等 。
分数表达（以文本中 “two - thirds” 为例 ）
文本例句：Almost two - thirds of the world’s population live in Asia.（世界上几乎三分之二的人口生活在亚洲 。）
解析：“two - thirds” 是分数表达，结构为分子用基数词（two ）、分母用序数词复数（thirds ），用于准确描述比例、占比等情况，在涉及数据、统计类表达时经常用到 。
