I've been travelling by train that had a bathroom, a little kitchen and sleeping rooms. It was like a home on the wheels. I would omit the "a" before train as it isn't necessary. Instead of "the" bathroom I would say "a" bathroom as it has not been mentioned previously. Likewise I omit the "the" before sleeping rooms.

The two sentences have a different meaning. The first implies that it is not necessarily obvious what "it" is for or means. An example could be an apology which is not sincere. And in time it may become obvious what the motive was for the apology. The second sentence indicates that it may become apparent what something is for, example could be a device which you are not familiar with, say a car engine component which you will use to repair your car.

The english in the question does not seem to be correct. I expect it should read something like.... the lecturing input's a pretty high standard..... if I am correct then: input's = input is. So 's replaces "is". This often done in English. When a letter or letters are omitted they are replaced by an aposthrophe ('). Examples: is not = isn't cannot = can't should not = shouldn't

How does she get on with.... the question is asking how is her relationship with the other person. The response could possibly be... she gets on well, they are frI ends. Or another response could be. .. she does not get on well with the other person. ... implying that there is some issue between the two.

sentences about a building

I had a text to write in English but some of the sentences seems wrong or unnatural to me. Could someone have a look a it. Thanks :)

Our work mainly consisted of a study case and an exchange with the XR architecture firm. We tried to understand and to analyze this complex building, to see if it reached its goal of revitalising the district of Laude. It was also in order to see whether or not a mixed-use building could reach the same goal as a functional mixing district and create a pleasant living environment.
Usually, this functional mixing is made at a district/neighbourhood scale and every building has a very precise function.
Considered as being to complicated to develop, mixed functions building are rare. Yet, by having a smart design, buildings could offer a great variety of functions and contribute to having more living cities in the same way that mixed districts do.

Through the example of the Block Tower we are going to demonstrate that mixed-use constructions can reach the objectives of functional mixing district and re-revitalize a district in Escheat.

The 1980s marked a new turning point in Rotterdam’s city-planning orientations: a new directive was born, that of modernity and the skyline.

About my day

Today I woke up at 6am. Because it was raining this morning I brought my husband to his job.
At midday, I had lunch at home.
I began work at 1pm and finished at 5pm. After work, I drove home.
