Summarize the points made in the lecture, being sure to explain how they respond to the specific points made in the reading passage.
Asteroids are large space objects made of rock and ice. There are hundreds of thousands of asteroids in our solar system. Though we often hear ideas about establishing colonies of humans to live and work on our Moon or our neighboring planet, Mars, some think that sending people to an asteroid would actually be the best colonization option for a number of reasons.
Low Gravity
To begin with, asteroids are often much smaller than planets, so they have lower gravity. When landing a spaceship, the craft would not be pulled as strongly or as forcefully toward the asteroid’s surface, making the landing safer than landing on the Moon or Mars; it would also allow a spacecraft to carry much more equipment needed to set up the colony. It would also be easier for the spacecraft to take off again, so the spaceship would need to carry considerably less fuel for the trip back to Earth.
Mining Valuable Metals
Next, some asteroids are rich in valuable elements and precious metals that are relatively rare on Earth, such as gold and platinum. An asteroid colony would be extremely profitable and a good source of these raw materials. The colonists or businesses sponsoring them could more than pay for the cost of their support by mining minerals and sending them back to Earth.
Easy to Reach
Finally, asteroids are a good option for colonization because some of them would be very easy to reach. There are a number of asteroids that periodically come within or near Earth’s orbit. Some of them actually get closer to Earth than our Moon. So these asteroids would be much easier and more affordable to get to and get back from than a planet like Mars, which would require a two-year trip in each direction.
The lecture challenges the specific arguments presented in the reading passage basically by these three following points.
To work against the first argument that the low gravity asteroids maintains are often beneficial, the professor suggested that low gravity presents risks sometimes for causing people losing muscle weight and bones density. Especially in the case of long-term staying.
And second, to disapprove the thought that profitable mining businesses, the whole picture should be considered as the cost of establishing a mining industry and setting up the transport are extremely high so that can come over than the profits this will make. On the other hand, if there is some other valuable metal resource found in Earth, the supplies increase, the price reduces.
At last, for the argument that those asteroids are easy to reach. It is true in a way, but it also can be much harder to come back somehow. Those asteroids comes close to the Earth, and at some points, they move far away, even further than the distance of Mars. Thus, our people may reach easily but take a huge mount of efforts to come back home.

We are expecting: No. of Words: 350 while No. of Different Words: 200
Better to have 5 paragraphs with 3 arguments. And try always support/against one side but compare two sides, like this:
para 1: introduction
para 2: reason 1. address both of the views presented for reason 1
para 3: reason 2. address both of the views presented for reason 2
para 4: reason 3. address both of the views presented for reason 3
para 5: conclusion.
So how to find out those reasons. There is a formula:
reasons == advantages or
reasons == disadvantages
for example, we can always apply 'save time', 'save/make money', 'find a job', 'make friends', 'get more information' as reasons to all essay/speaking topics.
or we can apply 'waste time', 'waste money', 'no job', 'make bad friends', 'get bad information' as reasons to all essay/speaking topics.
