请英文好的朋友帮助修改一下口语考试材料,除了修改语法错误外,还希望能够将语句修改的更“口语”一些.
In Shanghai buses are being replaced by an extensive underground rail network. Last week, the shanghai government announced that metro Line 11 is expected to start a pilot run in October. However, it’s worth noting that the traffic congestion in Shanghai is still a significant problem.
The previous North West Sydney government made some mistake in their urban planning, and one result was a much needed metro system being shelved. The current the government has chosen to extend the heavy rail network. Government think it could compromises the potential for future metro.
Singapore is considered as a typical and successful case of its urban transportation planning. Recently the Commuters in Singapore could take the metro for free before the rush hour on weekdays.

Answer 1

1.Shanghai government announced introducing Line 11 as pilot run in October last week.
2. Even with the addition of this line, traffic congestion in Shanghai will still be a significant problem. (Note: I changed the sentence to include reference to Line 11 is to tie in with your previous sentence of adding line 11 and the word 'still' in this sentence)
3. Sydney city council had made some mistakes in their previous urban planning. One of the mistake was shelving a much needed metro system revitalization in the northwest.
4. The current council has extended this rail network. City government thinks it can strengthen the potential in future public transit. (Note; I am not an Aussie, I only read your meaning from the words you wrote. If Sydney extend the metro line, you can't use the word compromise if extension is a good thing)
5. Singopore is considered a successful case in urban transportation planning. (Note: many cities in this world failed in transportation planning, so avoid using the word typical)
6. It is so successful and efficient that commuters can ride for free outside rush hours on weekdays just started recently. (this is to tied in with the word successful)
