2. Why was the writer happy to help her
mother?
3. What are the three creative steps that
the writer took to catch the snakes
without hurting them?
4. Why did cooling make the snakes less

2. Why was the writer happy to help her
mother?The mother was upset because a family of snakes had made their home near the house.The writer was happy because it gave her an opportunity to help her mother and invent something to catch the snakes without hurting them at the same time.Now check the answers.3. What are the three creative steps that the writer took to catch the snakes without hurting them?These are the three creative steps the writer took to trap the snakes by cooling them and making them sleepy so she could catch them.
Step 1: She bought a stainless steel ice- cream maker and froze the bowl. She added ice cubes to the top of the bowl to keep it cold. She placed it over the snakes‘habitat during the day so that the snakes would become sleepy and could be easily caught.
Step 2: As above she did the same but placed the bowls over the snakes’ habitat in the evening.
Step 3: As above but added a net to catch the snakes.4. Why did cooling make the snakes less
active?Snakes do not have a way of keeping warm in their bodies. They get warmth from the sun and become more active at this time. When the sun goes down at night they cool down and become less active. So extra cooling to the snake would make them even less active and easier to catch. RetellingStage 1: Find a problem- catch the snakes but not harm themStage 2: Do research- look for methods of removal & the habits of snakesStage 3: Think of a creative solution- identify three possible approaches and choose the last oneStage 4: Test the solution several times- tried three times and finally succeededStage 5: Apply for a patentCareful reading重难点句式分析1.

我大概是把书忘在家里了。

Between the outside and inside walls of the bowl there is some jelly, which freezes hard when cooled.句中的cool与which (实际指some jelly)之间构成逻辑上的动宾关系，需用v-ed。“连词+v-ed”构成省略了的状语从句More examples:
But once picked up, they tried to bite me. (P20)
Once begun, the project can’t be stopped.
When asked how to solve the problem, he didn’t give any answer.在碗的内壁和外壁之间有些胶状物，冷却后会冻结。定语从句连词if, unless, after, before, as, when等后还可接v-ing、介词短语、不定式等构成省略。While waiting for the bus, he looked through
the morning newspapers.

Although built before the war, the engine is still in perfect order.

Remember to include one change to your invention in case it doesn’t work the first time. It you want, you can choose your own problem for No. 4.P22 3Problem 1: The ripe apples on your apple tree are too high for you to reach. What can you invent to pick the apples in comfort?Problem 3: You want to catch fish but not hurt them when you do so.

One possible answer for Problem 2:
Remove the bottom from each of the bottles.
2. Stick the bottles together with the glue and tie them with string to form a solid wall.
3. Cover them with the fishing net to hold them secure.
4. Pour water down the bottles to encourage plants to grow up inside them. The plants will make a vegetable wall which will keep the sunshine out and protect the people inside from anyone who wants to look in.
5. Make a roof of empty bottles. This means it will not be too heavy.
6. Put the roof on after the plants have grown so that the walls are very secure and steady.When I ________ my mother in the countryside, I was told that there were snakes near our house and she wanted me to help her _________ them. I felt proud to have such a chance to __________ myself ____ inventing something to catch the snakes but not to hurt them.
