"on your way home late at night.You should walk the street which have a large pepple.You msut alert suspect people who have follow up you come back home."
更正如下:
"If you go home late at night,you should walk on the streets where there are many (a lot of) people.You must also be on that alert that there were no suspicious characters tailing you from behind."
注:
(a) walk the street =walk on the road/street;
(b) a large people = many (a lot of) people
(c) alert = on the alert/ must be alert...
(d) suspect = suspicious (characters)
(e) follow up = tailing you /following you from behind...
