The reading primarily talks about three challenges we face when it comes to storing CO2 underground. However, the listening puts forward solutions to overcome each obstacle.

Firstly, the reading claims that it's not clear whether underground sites for storing CO2 have enough space. Conversely, the speaker refutes this point by stating that under high pressure and temperature can gas turn into supercriticialsupercritical(misspelling) liquid, a more compressed state. In this way, CO2, normally gas, can be converted into supercriticialsupercritical(misspelling) liquid, which takes up less space. Hence, this approach can decrease the space we need to store CO2.

Secondly, the reading asserts that it poses risks on human health since high concentration of CO2 is significantly unsafe if CO2 is leaked. In contrast, the speaker finds a method to address this concern. Based on reasearchresearch(misspelling), only CO2 close to the underground has the possibiltypossibility(misspelling) of leaking. Only people breathe air close to the ground will be affected, like sleeping on the ground when hiking. Even if people sleep on the ground, we can utilize a monitoring device to alert people when CO2 is leaked.

Finally, the reading posits that creating technology and inventing infrastructure for capturing, transporting and storing CO2 is at high costs. Nevertheless, the speaker believes that costs can be offset by financial benefits. To state it more clearly, storage sites are deep underground layers of rock, which contains methane, a kind of valuable fuel. When CO2 is injected into these rocks, methane will be released. As a reslutresult(misspelling), we can collect and sold methane, and the money we gain can partly make up for the high cost.

In summary, each challenge for storing CO2 undergoundunderground(misspelling) made in the thethe(Word repetition (e.g. 'will will')) reading passage is effectively addressed by the listening.

Section Title: 6.文章修订

The reading primarily discusses three challenges associated with storing CO2 underground. However, the listening offers solutions to overcome each obstacle.

Firstly, the reading claims that it is unclear whether underground sites for storing CO2 have sufficient space. In contrast, the speaker refutes this point by stating that under high pressure and temperature, CO2 can be transformed into a supercritical fluid, which is more compressed than its gaseous state. By converting CO2 into a supercritical fluid, less storage space is required.

Secondly, the reading asserts that leaked CO2 poses risks to human health due to its high concentration. The speaker counters this concern by referencing research that shows leaked CO2 usually stays close to the ground, only affecting those who breathe air near the ground (e.g., while sleeping during camping). To mitigate this risk, monitoring devices can be installed near storage sites to alert people when leaks occur.

Finally, the reading posits that developing technology and infrastructure for capturing, transporting, and storing CO2 comes at a high cost. Nevertheless, the speaker believes these costs can be offset by financial benefits. Specifically, storage sites are often located in deep underground layers of rock containing methane—a valuable fuel source. When CO2 is injected into these rocks, methane is released and can be collected and sold. Profits from selling methane can partially compensate for the high costs of carbon dioxide storage.

In summary, each challenge regarding underground CO2 storage presented in the reading passage is effectively addressed by solutions proposed in the listening segment. (253 words)

The reading primarily talks about discusses three challenges we face when it comes to associated with storing CO2 underground. underground (changed "talks about" to "discusses" for a more formal tone). However, the listening puts forward offers solutions to overcome each obstacle.

Firstly, the reading claims that it's not clear it is unclear whether underground sites for storing CO2 have enough space. Conversely, sufficient space (replaced "it's not clear" with "it is unclear" for formality and clarity). In contrast, the speaker refutes this point by stating that under high pressure and temperature can gas turn temperature, CO2 can be transformed into supercriticial liquid, a supercritical fluid (corrected "supercriticial liquid" to "supercritical fluid"), which is more compressed than its gaseous state. In this way, CO2, normally gas, can be converted By converting CO2 into supercriticial liquid, which takes up a supercritical fluid, less space. Hence, this approach can decrease the storage space we need to store CO2. is required.

Secondly, the reading asserts that it leaked CO2 poses risks on to human health since due to its high concentration of CO2 is significantly unsafe if CO2 is leaked. In contrast, the (rephrased for clarity). The speaker finds a method to address counters this concern. Based on reasearch, concern by referencing research that shows leaked CO2 usually stays close to the ground, only CO2 close to the underground has the possibilty of leaking. Only people affecting those who breathe air close to near the ground will (e.g., while sleeping during camping) (clarified example). To mitigate this risk, monitoring devices can be affected, like sleeping on the ground when hiking. Even if people sleep on the ground, we can utilize a monitoring device installed near storage sites to alert people when CO2 is leaked. leaks occur.

Finally, the reading posits that creating developing technology and inventing infrastructure for capturing, transporting transporting, and storing CO2 is comes at a high costs. cost. Nevertheless, the speaker believes that these costs can be offset by financial benefits.

In summary, each challenge for storing CO2 undergound made regarding underground CO2 storage presented in the the reading passage is effectively addressed by the listening.solutions proposed in the listening segment (rephrased for clarity and conciseness).
