The lecture is mainly discussing the three advantages to use hydrogen-based fuel-cell engine to replace the internal-combustion engines in the car. By challenging the statement in the reading passages, the professor listing contradictory reasons to the reading.

First, in the reading, some may think, since there are abundant hydrogen in the nature, that it may take no hard to obtain them from the nature.

The professor refute the statement by explain that although hydrogen was very rich in the nature, but it could not immediate to use them in the engine. To apply for engine, liquid hydrogen needed. But it was very hard to produce and store the liquid hydrogen. So it would not so easy as the reading stated.

    Second, in the reading, some may believe hydrogen is a clean fuel. In the lecture, the professor pointed out although use hydrogen as a fuel may not pollute the environmental, but in the process to produce the hydrogen, it may causes severe pollution.


Finally, in the reading, some may consider the new engine as a considerable selection for car owner, for it could twice efficient than the internal-combustion engine could.But professor opposite the statement by point out that the car owner who used the new engine would pay much more than use internal-combustion engines, because the new engine use a kind of rare metal, which could cost them more.

The lecture is mainly discussing the three advantages to use hydrogen-based fuel-cell engine to replace the internal-combustion engines in the car. By challenging the statement in the reading passages, the professor listing （lists）contradictory reasons to(用againist会不会好点) the reading.
    First, in the reading, some may think, since there are abundant hydrogen in the nature, that it may take no hard （我觉得这个搭配有点别扭，但也不知道该怎么改……）to obtain them from the nature. Compared to the conventional engine which used fossil fuel, the new engine would （be）more attractive. The professor refute （加s）the statement by explain（ing） that although hydrogen was（怎么变成过去式了，应该都用现在式的……下同） very rich in the nature, but it could not immediate to use（it 做主语，应该是be used） them in the engine. To apply for engine, liquid hydrogen needed. But it was very hard to produce and store the liquid hydrogen. So it would not so easy as the reading stated.
     Second, in the reading, some may believe hydrogen is a clean fuel. In the lecture, the professor pointed out although use hydrogen as a fuel may not pollute the environmental, but in the process to produce the hydrogen, it may causes severe pollution.

Finally, in the reading, some may consider the new engine as a considerable（和前面的consider有点重了，换个词会更好） selection for car owner, for it could twice efficient than the internal-combustion engine could.But professor opposite（s） the statement by point（ing） out that the car owner who used the new engine would pay much more than use internal-combustion engines, because the new engine use a kind of rare metal, which could cost them more.
内容总结的不错……但细节的语法要注意，第三人陈单数，介词后面加doing~~~写完应该检查一遍~~~建议有些短句可以用定语从句合并成长句……加油加油·~
