hey, Anglika, thanks a lot for your tip on BNC. the site is amazing. only one question: the results that i get for a search are always correct examples of how to use the language, right?Google is not a reliable tool. It is a moderately useful one. The problem with internet searching is that the same source will be cited in any number of search engines, and therefore the statistics are innately skewed.
As a guide to good syntax = be very careful. Many blogs are extremely poor written English but turn up on searches, which may then appear to give them authority.
If in any doubt, cross reference the phrase/sentence you are concerned with in the BNC and ANC - or ask here.
