I would not suggest that you use Chinese. It takes long time to translate. You have only 1 minute and 30-40 seconds for each CR.
You need to understand each sentence. If you cannot, there is nothing we can do in the short run to help you improve.
If you can understand each stand-alone sentence, try to link them up by reasoning. Think about what each sentence is. For example, premises or conclusion, or required conditionsm etc.
Then use your knowledge in logic. I think you should be good in this part.
