教案：

Hello and welcome to Xiaoming Yingyu. Welcome to class for today!
歡迎來到小明英語

So our slang for today is "change gears" or “shift gears"
我們今天的俚語是“換擋”

If you like riding a bike, or driving a car, you might know what gears are
如果你喜歡騎車或者開車，你應該知道檔位

Gears are what you change when you want to change speeds
變換檔位可以變換速度

For example, when I ride a bike, and I’m riding on some flat ground
當我在平路上騎車的時候

I usually keep the gear pretty high
我一般用比較高的檔
because I can push a lot, and go really fast
這樣我可以使勁蹬并且速度很快

But, if I’m going up a slope
但是當我上坡的時候

then I have to shift gears into a lower number so that I can go up
我需要把檔降低

And it’s slower, but it’s a lot easier
雖然慢一些，但是上坡很省力

So the basic meaning of changing gears is changing speed
所以換擋的意思就是變換速度

But it can also mean to change direction quickly
但是它的意思也是快速的變化方向

for example, if you’re having a conversation with someone, or if you’re writing a passage
可以在和別人聊天或者寫作的時候使用

For example, I was talking to someone about
例如我和別人在聊我課上學到的內容

what I was learning in class, and I wanted to talk about news
然后我想聊新聞

So what I said was, "blah blah blah…and that was my last class for the day. Now, let us shift gears
我說，dDpp;RfDra。rEP7n|F.g)。|r|qG56Gai.AI;9。 這是我這天的最后一節課Bz(F!tb*Q8sQni9kJ5。現在讓我們換換擋70PNj(NUwK@a2h,G。

Did you hear about the escaped llama in Guatemala?"
你聽說了那只從危地馬拉逃走的草泥馬嗎？

So it’s kind of related to cars and bikes
所以是和騎車和自行車有關聯的

but instead of changing speed, it’s all about changing direction
但是是關于變換方向而不是變換速度

Now, let’s change gears and talk about sentence structure
現在讓我們來講每日句型

Here’s our example for today. Computers are a tool from which you get a lot of information
這是今天的例子：電腦是一個可以獲取很多信息的工具

"A is a B from which you get C"
A是B，從B里你可以獲取C

We have one more example. Oranges are a fruit are a fruit from which you get lots of Vitamin C
還有一個例子sR*,ZfP3yXm,!*5[CSar。橘子是一個可以獲取到很多維他命D的水果

Why don’t you try making a sentence? You can post it in the comments
你也來試試吧%Y^N(*^*u%f3。你可以把自己造的句子寫在評論里

And today, we’re trying something new. I’m going to tell you about where a word came from.
今天我們來試試一個新的環節e!*%%lH7jp-ogx|qY。讓我來告訴你一個單詞的根源

There is a word for this: etymology
這個術語叫做詞源學

Because English is a mixture of a lot of languages
因為英語是由很多語言構成的

learning the etymology, or history and origin behind a word
了解一個單詞的歷史和根源

will unlock the meanings for a lot of new words
可以讓你知道很多單詞的意思

A good word to start with is the one I just taught you
拿剛剛說過的單詞來講

An "etymon" is a root, from which another word can be created.
etymon是一個詞根，可以用來去造另外一個詞

In Greek, "etymon" meant the pure meaning of a word
在希臘語里，etymon的意思是一個單詞的純意

And so you can hear "etymon" is the first part of "Etymology"
你也可以看到，etymon是etymology的一部分

The "pure meaning of a word" is the root behind the word "talking about the history of words"
“一個單詞的純意”是“研究單詞歷史”中的詞根

A little confusing, right? I have a few more for you
是不是被我說暈了？我們再試試吧

If you want to talk about an etymon, you can call it the "etymic" form of a word
如果你在說etymon，你可以把它叫做一個單詞的etymic形式

So "etymon" is the noun, "etymic" is the adjective. You can tell because of the "ic" at the very end
Etymon是名詞，etymic是形容詞，因為它是以ic結尾的

If you see a word that ends in "ic" it should make you think, right away, "aha!" that’s an adjective
當你看到一個單詞以ic結尾，你應該立刻就直到它是一個形容詞

And a person who likes to study etymology is an etymologist
一個喜歡研究etymology的人是etymologist（詞源學家）

And soon, we will all be etymologists!
我們很快都會成為詞源學家啦

They like to do a certain thing in their free time, you can guess what that’s called?
詞源學家都喜歡做一件事，是什么呢？

Yes! They like to etymologize
對，就是etymologize（研究詞源學）

That is the verb form. And they like to talk about all sorts of etymological things
這是動詞bC4Yr]Jfltun。他們喜歡討論etymological things（詞源學有關的事情）

"Etymology" remember, is the noun. If you add "ical" it also turns it into an adjective
要記住，etymology是名字J6(t)0]|th。如果你加上ical，它就成為了一個形容詞
