Afterward, it took Tang Zhifei a long ti to calm his emotions, wasting most of the class before finally starting the Chinese lesson.
As for the matter of class division, although it was still sowhat troubleso, that was a problem for next June or July.
At the mont, there were more pressing matters at hand.
That was the problem copied by Zhang Xiaoke.

Hearing this, Li Zheng felt for the first ti that Jiang Qinghua was indeed a talent worth shaping.
After being around for so long, he was finally getting on the right track, not bad at all.
Since it was a competition, Li Zheng did not cheat by speeding up but looked down at the questions as usual.
Not to ntion, although he had recently tackled a massive volu of chemistry questions,
seeing physics questions felt sohow more familiar.
It was like a man who had traveled through the world’s dust, yet in the end, still loved his hotown cuisine the most.
Li Zheng stopped thinking further and began to analyze the question—
[In August 2011, China’s spacecraft "Chang’e-2," after completing its lunar mission, flew for the first ti from lunar orbit to the Sun-Earth Lagrange Point.]
[At that point, "Chang’e-2" and the Earth revolved around the Sun in a synchronous circular motion.]
[The masses of the Sun and Earth are known as MS and , and the distance between the Sun and Earth is R.]
[The equation that the distance x from the Earth to this Lagrange Point satisfies is_______.]
[From this, x is approximately ________. (Given that when λ
