正在创建课程...
1
Janet lives downtown in a big city.
2
She feels there are too many paved roads.
3
Here's a map.
4
These are the roads, and these are the blocks of buildings.
5
The city has a rule.
6
If the roads cover more than 30 ,000 square meters of the downtown, They have to build more parks.
7
you Janet decides to calculate the area of the roads.
8
you Each road is a long and skinny rectangle that is 10 meters wide.
9
The horizontal roads are 10 meters by 560 meters.
10
The area is width times length.
11
10 times 560 is 5600 square meters.
12
There are four horizontals.
13
5 ,600 times 4 is 22 ,400 square meters.
14
That's the area of all four horizontals.
15
the vertical roads are 10 by 3 :40.
16
10 times 340 is 3400 square meters.
17
There are six verticals.
18
3400 times 6 is 20 ,400 square meters.
19
That's the area of all six verticals.
20
Now, we add the area of the horizontals plus the area of the verticals.
21
The total is 42 ,800 square meters.
22
But when we added the horizontals, and the verticals, we actually added the intersections twice.
23
we need to subtract the extra intersections from the total.
24
The intersections are 10 by 10 squares.
25
the area of one intersection is 10 times 10.
26
were a hundred There are 24 intersections.
27
100 times 24 is 2400 square meters.
28
we subtract 2400 from the total, to get a road area of 40 ,400 square meters.
29
That's greater than the 30 ,000 square meter limit, so the city will have to build more parks.
30
Solving composite area problems requires creativity, First we found the area of the horizontals and then the verticals.
31
Then we added those together.
32
you Finally, we found the area of the intersections which we counted twice, and subtracted that from our total.
33
Let's hope Janet can convince the city to build more parks.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
