今天又是超级棒的一天

动手排好了凹字形的课桌

而且还进行了及时的fun quiz

The first period starts with a fantastic quiz on toursim which most students got high scores, then the class moves to 3.5 on renewable energy and non-renewable energy with examples, such as how dinosaurs becomes fossil fuels that we can use.

We also talked about various kinds of energy consumption with funny pictures.

Then we have a second period with geographical skills. After a review on scale, grid and square references, directions, relief and gradient, we had a quiz to figure out if everyone is catching up.

经常容易读错的内容：

我们一起再过一遍，类似于我们学过的经纬度，先读东西经度，再读南北纬度，经线以本初子午线为0度经线自西向东变化，纬线沿着赤道向南北两极逐渐变大。同样的，自西向东变化的（在地图上体现为竖着的线）即为自西向东变化的，是首先要读的(first read)，在读自南向北变化的（在地图上体现为横着变化的线(second read)。

There are some exam style questions.

What is E's four figure?

E is located at 9447.

So it is your turn to find out where is F located at (in four figure)?

Then there is also a possibel exam question for you when printed out, can you work out the gradient along E and F. If the examiner wants to be tricky, it will say, along the road E and F. In geography, we tend to use the percentage, so you can get an inspiration from this maths figures:

此图中的坡度百分比对应的才是我们地理卷中的Gradient.

所以算法应该是运用三角形计算中烂熟于心的任意边长公式吧，可以从图中得出高程（其中一条短边），和两点之间的直线距离（也就是长边）。

【提示：b^2=(c^2)-(a^2)，b=Distance, a=Height】

Gradient=（ H/D）*100%

今天就是这样，明天继续哦～
