5、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. Find another flier. If you choose to make a remote control airplane,

6、 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. This is essentially for the flying models because they may not fly wit

7、hout 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 many will let you choose yourself. Most model airplanes are made of bal

8、sa 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 airplane.6. Carefully assemble the model parts together. If there is an engi

9、ne （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 electrical panel.2. Inspect the circuit breaker arrangement for unused loc

10、ations.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.8. Set the circuit breaker handle to the OFF position.9. Install the

11、 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 to do. State it clearly, and use proper English. Instead of writing gr

12、ocery 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 the most important things first. If its a repair list （around the hous

13、e）, 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. Make it noticeable. Write in bright colors or put it in a noticeabl

14、e 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 determine your intended location （usually by measuring the distance

15、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, slender tool with a pointed end that allows you to create a small inde

16、ntation 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. Determine the appropriate size bit for drilling your pilot hole. As a genera

17、l 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 screws threads to grip into. Exact recommendations for pilot hole di

18、ameters 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 always be made bigger, but not smaller.4. Drill the pilot hole. After choo

19、sing 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 screws length. Back the bit out carefully5. Install the screw. Once the pi

20、lot 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 process for each screw used.Self Asking Questions: How to write work steps?

The materials should always check out

25、 and put back at once, and you should fill the logistic form every time. Should I take the same form every time? No, you need one form every time you check out and check in any piece of tool. I see. Do you need a hand with the assembly? yes, just check the sequence of the work. So the first step is

26、to inspect the modules and connectors? yes, you need to make sure parts that prepare to be installed are deburred. Then, you check the size and different circuitry. Do I need to check the number on these plates? Of course, the number identifications have to be inspected before dispatch.Task 1 Group
