Learning Objectives
By the end f this lessn, we will be able t:1. Use the “inf-challenges-impact” structure and passive vice t write abut an inventin. 2. Analyze the Wright brthers‘ prblem-slving prcess and apply the structure t a chsen inventin.3. Extract key infrmatin frm a mdel text and use a framewrk t rganize independent writing.
What did yu see in the vide?Hw did the inventin f the plane change the wrld?
Wh invented the first plane?When was the first flight made?Why did they want t invent it?
Read the text and cmplete the chart.
The inventin f the plane has greatly changed the wrld. Hwever, it seems that its inventrs, Orville Wright and Wilbur Wright, were nt lking t change the wrld at all. Rather, they just wanted t fly like birds. T slve the prblem f heavier-than-air flight, the Wright brthers began wrking with gliders. There were tw main challenges. The first was hw t get the glider int the air. The secnd was hw t cntrl it nce it was flying. Fr bth prblems, they fund their slutin by lking at hw birds flew. After they slved these prblems, they added an engine t the glider. Then, in December 1903, the wrld’s first plane flights were made. The inventin f the plane has made ur travels arund the wrld much easier and faster. Jurneys that nce tk days, weeks, r even mnths, can nw be made in nly a few hurs. As a result, cmmunicatin amng peple in different cuntries is nw much easier, and the wrld has becme a much smaller place.

The high-speed train is ne f the mst imprtant inventins in China. It was invented and develped by Chinese engineers. It was invented t make travel faster and mre cnvenient, especially fr lng-distance jurneys. The main challenge was t build railways that culd supprt very fast trains. The engineers slved the prblem by using advanced technlgy and new materials. Finally, the first high-speed train was put int use in 2008. The high-speed train has made travel much easier and faster. A jurney that nce tk 10 hurs can nw be made in nly 3 hurs. As a result, peple can travel between cities mre freely, and the cuntry has becme much clser.
