Jenny: Ouch! I stepped on something and it hurts!
Danny: Is it a shark
Jenny: You’re kidding me. It’s just some plastic. Look, it’s a plastic bottle.
Danny: Plastic It should be in the bin, not in the sea.
Brian: I’ll go throw this bottle in the recycling bin.
Danny: Look! That man over there is leaving his garbage on the beach. Such behaviour is harmful to the ocean and its creatures.
Jenny: Exactly! Last week, I read that a whale died with more than 20 plastic bags, a toy gun, and other rubbish, 10 kilos in all, in its stomach.
Danny: That’s such a terrible story. If we do nothing, the situation will get worse.
Brian: How about cleaning up the beach
Danny: Sounds good. But it would take too long. There are only three of us!
Jenny: We can ask our family members to help.
Brian: Good idea!
They explain the plan to their family members, and everyone agrees to help. They spend the rest of the afternoon picking up bottles, plastic bags, and all kinds of garbage on the beach. Before leaving, they take a final swim. They feel proud that they made a difference at the beach.

4. If we do nothing, the situation will get worse.
如果我们什么都不做，情况会变得更糟。
(1)结构分析：这是一个主从复合句。主句是the situation will get worse，其中the situation 作主语；will get 作谓语；worse 作表语。从句是由If 引导的条件状语从句，we 作主语；do 作谓语；nothing 作宾语。
e.g. If you study hard, you will get good grades.
如果你努力学习，你就会取得好成绩。
If it rains, we will stay at home.
如果下雨，我们就会待在家里。
“If + 从句，+ 主句.”表示“如果……，……就会……”。注意：在if 引导的条件状语从句中，从句用一般现在时，主句用一般将来时，即遵循“主将从现”原则。
(2)worse adj. 更糟的；更坏的

What’s worse 更糟糕的
e.g. If you never try, your life is only going to get worse.

他们无法就晚餐地点达成一致。
6. They spend the rest of the afternoon picking up bottles, plastic bags, and all kinds of garbage on the beach. 下午剩下的时间，他们在海滩上捡瓶子、塑料袋和各种垃圾。
(1)the rest of 表示“剩余的”。当 “the rest of +名词、代词” 作主语时，谓语动词的单复数取决于of后边名词或代词的数。
e.g. The rest of the eggs have gone bad already.
其余的鸡蛋已经变坏了。
The rest of the bread has been eaten up.
剩余的面包已经被吃光了。
(2)all kinds of 表示“各种各样的”。后接不可数名词或可数名词复数，kinds 前还可用 many、different、these 等词修饰以表达不同的含义。
e.g. There are different kinds of animals in the zoo.
在动物园里有不同种类的动物。
We saw many kinds of birds in the forest.
我们在森林里看见许多种类的鸟。
