ответ - Came, т.к. В паст симпл используется окончание -еd или вторая форма глагола
А Come - неправильный глагол
hello, my friend!
i was very glad to get a letter from you.
you asked me about environment. i want to give you some advices how you can protect the environment. you must sort your rubbish. plastic bottles, juice cartons, and cardboard can be taken to a recycling bank. you can use
recycled papers to help save trees. you can avoid buying plastic since is difficult to recycle. let’s keep the streets around us tidy, neat and clean, so don’t drop litter, put it in the bin! you can plant a tree. by planting and growing more trees, we will help reduce the pollution, lower energy costs, improve the surrounding. you see my advices are very simple. every person can do it. and you can do it too.
sorry. i need to go.
bye!
