7、ame them? Work contentsTask 1 Read the following work orders and try to connect them with the right picture.a. Making a model airplaneSteps：1. Select a model. After you know whether you are going to build static (nonflying), flying with or without remote control, you can decide on the exact model.2.

8、 Find another flier. If you choose to make a remote control airplane, it helps to know someone else who also builds and flies too. There are many online forums that have lots of experienced builders.3. Download plans. Its recommended that you download a professionally designed plan for your model. T

9、his is essentially for the flying models because they may not fly without keeping the symmetry and proper measures. Its a must for the static models too because they must represent a real airplane in exact scale.4. Choose material. Some model airplane plans may be tied to a specific material, but ma

10、ny will let you choose yourself. Most model airplanes are made of balsa wood, foam or plastic, but you may decide to use robust paper or clay for the static models.5. Cut the parts. This is the most important part of the work. Make sure you properly measure and cut the different parts of the airplan

11、e.6. Carefully assemble the model parts together. If there is an engine (when building an RC aircraft) make sure its properly installed.7. Paint it. Painting is an easy and fun stage but still requires patience and good taste.b. Installing a circuit breakerSteps:1. Turn off power supply to the elect

12、rical panel.2. Inspect the circuit breaker arrangement for unused locations.3. Remove the electrical panel cover.4. Test the panel for power.5. Locate an unused space above, below or between existing circuit breakers.6. Select the correct circuit breaker.7. Locate the circuit breaker mounting points

13、.8. Set the circuit breaker handle to the OFF position.9. Install the circuit breaker by aligning with the unused space in the panel.10. Connect the circuit.11. Remove all foreign objects.12. Install cover.13. Test.14. Identify the circuit.c. Making a to-do list1. Think of everything you/they need t

14、o do. State it clearly, and use proper English. Instead of writing grocery store, write Go to the grocery store to buy some Chunky Monkey ice cream2. Use good handwriting3. Put a date or day on it. It helps a lot if they know when to do it by, so they can feel ahead of their schedule.4. Prioritize t

15、he most important things first. If its a repair list (around the house), put the most important problems first. If its a big list, break it into manageable or incremental one-weekend or one-day projects 5. Organize the list to get it done quickly. Group the things in the same time or same location.6

16、. Make it noticeable. Write in bright colors or put it in a noticeable place.d. Making a pilot hole1. Mark the location of your intended hole with a pencil. If it is crucial that the screw is installed in a precise location, you may want to mark the spot with a pencil on the material. Use a ruler to

17、 determine your intended location (usually by measuring the distance from the edge of the materials surface), tracing along the ruler with a pencil. At the desired distance along the line you drew, make a small mark with the pencil.2. Create an indentation using a center punch. A punch is a small, s

18、lender tool with a pointed end that allows you to create a small indentation in the work surface. This indentation will help keep your drill bit from slipping when starting the pilot hole. Position the tip of the punch over your pencil mark, and then strike the punch gently with a hammer. 3. Determi

19、ne the appropriate size bit for drilling your pilot hole. As a general rule of thumb, your pilot hole should be slightly smaller than the diameter of your screw. This will remove as much material as possible, which will reduce the likelihood of splitting, but will still leave enough material for the

20、 screws threads to grip into. Exact recommendations for pilot hole diameters based on screw sizes can be looked up online. However, a visual check of your drill bit against the screw will suffice for most applications. It is best to err on the smaller side when choosing a bit; a pilot hole can alway

21、s be made bigger, but not smaller.4. Drill the pilot hole. After choosing a bit and fitting it into your drill, position the tip of the bit into the indentation you created with the center punch. Holding the bit at the angle you want the screw positioned, drill the hole to a depth equal to the screw

22、s length. Back the bit out carefully5. Install the screw. Once the pilot hole is drilled, you can install the screw. Fit your drill with a screwdriver bit and position the screws tip into the pilot hole. Drive the screw in, being careful to angle it to follow the path of the hole. Repeat this proces
