Choosing the right drill for the job
Most jobs can be done using a simple rotary drill. It can be used for wood and plywood. It can also be used for drywall, plaster, copper and steel. Of course, you need to have the right drill bits too.
What about for harder materials like brick and concrete? A hammer drill works well for blocks, brick, mortar and stone. A rotary hammer works best for materials like concrete and cement.
Sometimes the terms hammer drill and rotary hammer are used to mean the same tool. However, a hammer drill chips away at the material. A rotary hammer pounds away at it to make a hole.

Electrician
Occupations Outlook
The job of an electrician involves putting in and maintaining electrical power systems. This is done in homes and businesses.
The work of an electrician is occasionally demanding. Electricians must lift heavy objects and climb ladders.
The work may require them to bend, stand, kneel, or stoop down low for long periods.
To be successful, electricians need to work fast. In order to grab and release tools quickly, they wear a tool belt. To prevent electric shook, electricians usually turn off the power source before working. They turn on the power when they are done. Electricians also use sharp tools to split wires.

Fixing Underground Wires
Fixing underground wires sounds difficult. But it’s actually simple. You just need to splice some wires.
To begin, switch off the electricity. Accidental shocks are always a risk when working with electricity. Next, test the electricity to make sure it is off. Push a button
on the same circuit. If it is safe, dig into the ground. Inspect the wires, and find the damaged part. Cut it off. Next, strip the insulation off the wires. Twist the ends of the wires together. Then, pull on them to make sure they are joined. If they are, bind the ends together with tape. After that, install I waterproof insulation plastic covering on the wires. Then connect the electricity.
Exercises

1. What are the instructions mostly about?
A why it is important to replace wires
B how to fix a damaged wire
C what insulation is made out of
D how to inspect an electric circuit
2. Why should the electricity be switched off?
A to make sure the wires aren't damaged
B to avoid getting shocked by the wires
C to make it easier to find the wires
D to check that the wires are connected
3. What is the last step in the instructions?
A strip the insulation from the wires
B inspect the underground wires
C install waterproof insulation

Measurements
1. Read and translate the text.
Know Your Measurements
Fasteners and tools use imperial measurements or metric, and knowing the difference is important. It prevents you from rounding off a fastener, damaging tools, or causing injury. If you don’t know an item’s size, use a micrometer or other caliper to measure it. Check centimeters or millimeters for metric tools. Look at inches for imperial tools.
You will also need to know larger measurements, such as feet, yards, and meters. These measurements are often used in building plans.
Temperature measurements are also important to know. Some countries measure degress using the Fahrenheit scale and others use the Celsius scale. You may need to convert from one scale to the other.

Types of Wires
Read and translate the text.
There are many different types of electrical wire and cable. Knob and tube (K& T) wiring is one of the oldest types of wiring. Older types of cable are armored cable (AC) and metal-clad (MC) cable. Both of these are insulated by steel. These were replaced in newer construction by nonmetallic (NM) sheath cable. However, replacement is not required if the wire or cable jacket is still good. Check them to make sure there is no bare conductor or wire showing. Underground feeder (UF) cable and service entrance (SE) cable are used outdoors. However, SE cable is only approved for above-ground use.
