The title of the text is there to help you so the first thing to do with every text is to read the title and think what the text could be about.  
Look at any pictures or diagrams provided.  They are there to help you too.
Then skim read the whole text, 'survey' it very quickly, to find out the general theme and the main ideas and to see if your ideas were correct.  There may be a question about this and anyway, you will then be able to find the specific information you need to answer the other questions more quickly.

To practice this, you have five minutes to read through this text very quickly and answer these questions and the following exercise.

Hidden history:  the beetle's secret cycle of life

The deathwatch beetle is thought of as the devil's pest in churches and old houses, but in natural habitats it infests a wide range of decaying hardwoods.  It has been found in hornbeam, sweet chestnut, hawthorn, beech, ash, black poplar, elm, larch, spruce and yew but the two most commonly infested species in Britain are oak and willow.  In buildings, oak timbers are usually the focus of attack by the beetle, but alder, walnut, elm, larch and Scots pine can be affected too.  Deathwatch beetles attack wood that has been decayed by fungi, so it is the damp-prone parts of timbers, the ends and near leaking gutters and enclosed spaces, that are normally attacked first.
Adult beetles emerge from holes in the timber in spring, or occasionally in autumn.  They breed once and a week later the females lay eggs, usually about fifty, in small cracks on the surface of the wood.  Adults depend on stored reserves;  they do not feed so the adult lifespan is largely determined by body size and metabolic demands.  Emergent females rarely live for more than ten weeks, and males eight or nine weeks, at a temperature of about 20^o C.

The eggs hatch after two to five weeks and the larvae then wander across the wood to find suitable entry points through which to bore into the timber.  They then take between two and ten years to complete their development.  The larvae pupate in late summer to early autumn, each individual having constructed a pupal cell just below the surface of the wood.  After two or three weeks, the immature beetle emerges from the pupal skin, but then remains torpid inside the chamber until the following spring or early summer.  The mature beetle then cuts a perfectly round hole, three to five millimetres in diameter, and emerges covered in a fine wood powder.

When you are asked to look for specific information, you will need to analyse the questions carefully to make sure you know exactly what you are being asked for.  Go on to the next exercise, where you can practise this.  Don't worry about the specialised words you don't understand.  You should not need to know them to be able to answer the questions.
Make very sure you read the instructions carefully and follow them, though, for example whether it states the words must come from the passage or that they should be your own words.
