I forgot to include the following statements:

Thank you very much in advance.
1) Yesterday I read the following news in the newspaper.
2) On Sunday morning a young man, who was drunk (?) and had spent his Saturday night in a disco, drove his car at top speed in the centre of town.
3) When the police tried to pull him over (??), he speeded up, failed to see an elderly woman who was crossing the road on the zebra crossing and knocked her over.
4) He was finally arrested by the police while the woman was taken to the hospital by ambulance. 5) Luckily, she managed to survive. (Can you say just “She survived”?)
6) The Celts were important as far as religion and the organisation of justice were concerned (can you tell me a better expression?)
7) The Normans introduced the feudal system, according to which (?) the land was owned by the King, who gave it to the vassals in exchange (return?) for goods and military service.
8) The Knights and the villains were created by the chief vassals called barons.

Again, read carefully:

1) Yesterday I read the following in the newspaper.

2) On Sunday morning a young man, who was drunk and had spent his Saturday night in a disco, drove his car at top speed into the centre of town.

3) When the police tried to pull him over, he sped up, failed to see an elderly woman who was crossing the road on the zebra crossing, and knocked her over.

4) He was finally arrested by the police while the woman was taken to the hospital by ambulance.

5) Luckily, she survived.

6) The Celts were important as far as religion and the organisation of justice were concerned (can you tell me a better expression?)<~~laws? regulations?

7) The Normans introduced the feudal system, in which the land was owned by the King, who gave tracts and parcels out to his vassals in return for goods and military service.

8) The chief vassals, called barons, established the positions of knights and the villeins.

No problem! Here are the revised statements with some explanations:

1) Yesterday I read the following news in the newspaper.
To include this statement, simply mention that you read the news in a specific newspaper and on which day.

2) On Sunday morning, a young man, who was drunk (?) and had spent his Saturday night in a disco, drove his car at top speed in the center of town.
To include this statement, provide the information about the day (Sunday morning), the state the man was in (drunk), and where he spent the previous night (in a disco).

3) When the police tried to pull him over (??), he speeded up, failed to see an elderly woman who was crossing the road on the zebra crossing, and knocked her over.
To include this statement, mention the police's attempt to stop the man and his subsequent actions. Also, mention the elderly woman and the location where the incident happened (on the zebra crossing).

4) He was finally arrested by the police while the woman was taken to the hospital by ambulance.
To include this statement, state that the police ultimately arrested the man. Additionally, mention the woman's transportation to the hospital by ambulance.

5) Luckily, she managed to survive. (Can you say just "She survived"?)
Yes, you can say "She survived" to express that she managed to stay alive after the accident. This is a concise way of conveying the information.

6) The Celts were important as far as religion and the organization of justice were concerned (can you tell me a better expression?)
To better express this statement, you could say, "The Celts played a significant role in matters concerning religion and the establishment of justice." This rephrase adds more clarity to the statement.

7) The Normans introduced the feudal system, according to which (?) the land was owned by the King, who gave it to the vassals in exchange (return?) for goods and military service.
To clarify this statement, you can say, "The Normans introduced the feudal system, which involved the King owning the land and granting it to vassals in exchange for goods and military service." This rephrase provides better context and clarity.

8) The Knights and the villains were created by the chief vassals called barons.
To include this statement, state that the chief vassals, known as barons, were responsible for creating both the knights and the villains.
