1. 主句和其後的absolute片語有著對等的關係，片語改寫後用「對等連接詞」連接便可。
Here are the first three packs of cigarettes and the fourth one is to arrive next week.
( is + infinitive = 將會+ ...)

2. (a) 主句和其後的片語有著目的的關係，片語改寫後用「從屬連接詞」(in order to) 連接說明"followed"的目的。
A number of body guards followed the female candidate, in order for some to hold her briefcase and for some to protect her from being disturbed.

Form Longman dictionary:
[was/were to do something]
- used when talking about a time in the past to say what happened later
e.g. This discovery was to have a major effect on the treatment of heart disease.

(b) 主句和其後的片語有著情況的關係，片語改寫後用「從屬連接詞」(where = 在…的情況下) 連接便可。
A number of body guards followed the female candidate, where some were to hold her briefcase and some were to protect her from being disturbed.

(c) 因為亦有先後的關係，所以亦可用副詞(conjunctive adverb) "then 然後" 連接以說明時間次序。
A number of body guards followed the female candidate, (and) then some were to hold her briefcase and some were to protect her from being disturbed .

Amendment:(1)Here are three packets of cigarettes and the fourth one will arrive next week;(2)A number of body guards followed the female candidate closely so as to help her holding briefcase and protected her from disturbance. Yip
