Grammar Lens

到达：arrive at vs arrive in vs get to vs reach

表达用于例句
arrive at小地点arrive at the airport
arrive in大地点arrive in New York
get to通用get to school / get to the city
reach直接跟名词（无介词）reach the top of the mountain

Trap ❌ arrive to — arrive 后面永远是 at 或 in，不是 to reach to — reach 直接跟名词，不加 to

by + 交通工具（不加冠词）

by bus / by train / by car / by plane / by bike
但：on foot（步行）

by the bus ❌ / by a car ❌ — by + 交通工具之间没有冠词。

😂 Grammar Joke

介词的噩梦

An English teacher wrote on the board: “A woman without her man is nothing.”

She asked the boys to add punctuation. They wrote: “A woman, without her man, is nothing.”

Then she asked the girls. They wrote: “A woman: without her, man is nothing.”

同一个句子，标点不同，意思完全相反。 男生版：女人没有男人就什么都不是。 女生版：没有女人，男人什么都不是。

语法点：介词 without 的宾语不同，句意完全改变。without her man（没有她的男人）vs without her（没有她）。英语中介词 + 代词的搭配决定了”谁对谁做了什么”——一个词的位置就能翻转整个句子的权力关系。

🏛 语言文化光点

英语介词为什么这么难？因为每种语言”看空间”的方式不同

中文说”在桌子上”，英语说 “on the table”——这里刚好对应。但中文说”在墙上”，英语说 “on the wall”（和桌子一样用 on）。中文说”在天花板上”，英语却说 “on the ceiling”——英语觉得天花板也是一个”表面”。

中文说”坐在公共汽车上”，英语说 “on the bus”——因为英语把公交车当成一个平台（你站在上面）。但出租车用 “in a taxi”——因为出租车小，你是被包在里面的。

on the bus / on the train / on the plane（大型交通工具 = 平台） in a taxi / in a car（小型交通工具 = 包裹）

没有逻辑，只有英国人怎么看世界。多读书虫，多遇到，就记住了。

📖 Real English · 真实阅读

🔵 A Postcard from London

Dear Aaron,

I arrived in London on Monday. I’m staying at a small hotel near the Thames. On the first day, I went to the Tower of London. It was built in 1066. I stood in front of the Crown Jewels for twenty minutes — they were amazing! In the afternoon, I walked across Tower Bridge and took photos from the middle. At night, I had fish and chips at a pub beside the river. Tomorrow I’m going to Buckingham Palace. The Changing of the Guard starts at 11 a.m. I’ll be there before 10 to get a good spot. Wish you were here!

🔵 The International Space Station

The International Space Station (ISS) flies around the Earth at a speed of 28,000 km/h. It orbits the planet once every 90 minutes. Astronauts live on the station for about six months. They sleep in small cabins and eat food from special packages. In space, there is no “up” or “down,” so astronauts can sleep on the ceiling if they want. They exercise for two hours every day on special machines to keep their muscles strong. At night — which comes every 45 minutes — they close the window covers and try to sleep. The ISS has been in orbit since 1998.

🔵 Finding Your Way in Tokyo

Getting around Tokyo is easy if you know the system. Most tourists travel by train. The subway map looks confusing at first, but it is actually very logical. Each line has a colour: the Ginza Line is in orange, the Marunouchi Line is in red. You buy tickets at machines near the entrance. Trains arrive on time — usually within 30 seconds of the schedule. In the morning, trains between 7:30 and 9:00 are extremely crowded. At some stations, staff push passengers into the carriages. If you get lost, look for signs in English — most stations have them above the platforms.
