English for Writing Research Papers

2.1   Basic word order in English
English has a strict order in which words can appear in a sentence. S1 shows an 
example of this order.
 
S1.  The researchers sent their manuscript to the journal.
This order is rarely altered. It is:
 
1.  subject (the researchers)
 
2.  verb (sent)
 
3.  direct object (their manuscript)
 
4.  indirect object (the journal)
 The key is to keep the subject, verb, direct object and indirect object as close to each 
other as possible. This is illustrated in S2, which maintains the exact order of S1.
 
S2.   Last week the researchers sent their manuscript to the journal for the second time.
 
S3.   * The researchers last week sent for the second time to the journal their manuscript.
S3 is incorrect English. The position of last week and for the second time is wrong, 
and the indirect object comes before the direct object.
