Have a try
在含有宾语从句的复合句中,宾语从句要用陈述语序。因此当特殊疑问句作宾语从句时,一定要注意语序。
e.g: “Where did he go last month ” she asked.
特殊疑问词
一般疑问句结构: did + 主语+动原+其他?
引导词
陈述句结构:主语+动原+其他.
→ She asked where he went last month.
考点2 语序
特殊疑问词
(做主语)
谓语动词
陈述句结构:主语+谓语+宾语
→ The teacher wondered who watered the flowers.
当疑问代词what/who在特殊疑问句中作主语时,该特殊疑问句本身即是陈述语序,所以转变成宾语从句后无需再调整语序。
e.g:“ Who watered the flowers ” the teacher wondered.
宾语
无需再调整语序

Pair work
Part V
A: … Do you know why this rule was made
B: No, I don’t. Why
A: According to... This is the law of nature. People should live by it to ...
B: I see. Now I understand…
A: Yes, it helps...
Laws of nature are the fixed rules and patterns that control how nature works.They decide things like how seasons change, how plants grow, and where animals go.These laws exist on their own and people find them by watching and studying.
A: From May to September, no fishing is allowed in the sea. Do you know why this rule was made
B: No, I don’t. Why
A: According to studies, these months are the time for fish to have baby fish. This is the law of nature. People should live by it to protect the fish.
B: I see. Now I understand how we can keep enough fish for people.
A: Yes, it helps keep the ecosystem in balance.
Sample
According to the laws of nature ,no fishing then keeps fish from being caught too much and these months are the time for fish to have baby fish , so there are always enough fish.
This uses winter's coldness to keep fruit good. In winter, it's cold and dry, so fruit doesn't go bad easily. In this way, people can eat fruit at other times of the year.
It follows how bees make honey and have babies. Bees get nectar(花蜜)to make honey. This gives people honey to eat and also helps plants make more plants by moving pollen(花粉).
*Following nature's rules when fishing means there will always be fish for people to catch and eat. It helps keep the ecosystem in balance.
*Using winter's coldness to keep fruit good means less fruit won’t be wasted or thrown away . People can eat diferent fruits all year round.
*Keeping bees helps beekeepers make money from honey. lt also helps plants growbetter, which is good for nature and farming.
