The advantage of extracting expressions (to study) from a real exam task (rather then a random article) is that it is going to have more expressions that are adequate for the CAE exam level.
Here is a task from a very useful website http://www.flo-joe.co.uk/ It’s a Use of English Part 2 task.
Stress (0) is often called a 21st century illness but it has always been with us if perhaps with different names. These days we regard stress (1) as a necessary evil of modern living. Yet stress is not negative and without (2) it we would not enjoy some of the high points in life (3) such as the anticipation before a date or the tension leading up to an important match. All these situations produce stress but (4) provided/if you can control it and not the other way around, you will feel stimulated, not worn out. However, unlike these situations, (5) which are generally positive and easier to deal with, sitting in a train that is running late, (6) being stuck in a traffic jam or working to a tight deadline are much harder to manage and control and can be a significant cause of stress.
Stress is now recognised as a medical problem and as a significant factor (7) in causing coronary heart disease, high blood pressure and a high cholesterol count. Patients are often unwilling to admit to stress problems since they feel they are a form of social failure and it is important that symptoms (8) are/get identified in order to avoid unnecessary suffering.
My initial notes (that I should later copy into different sections of my notebook):
0. to be called sth
1 to regard sth as sth
2 Remember that sometimes we need an “it” in English where we don’t need it in other languages e.g. “I like it when you hug me”.
3 such as = for example = like (informal!)
4 provided = if
5 comma + “which” (an additional comment about something).
6 to be stuck in a traffic jam – I hate being stuck in a traffic jam (stick-stack-stuck)
7 a (significant) factor in sth/ing
