how can I use "radical"? it has three meanings so i don't know in which situation I can use its different meaning.

I have a diffculty in this sentense in one sense, the effect of a consumer's mood can be thought of in much the same way as can our reaction s to the behavior of our friends. my question : how can I explain the second "can"?<A> what does it mean？ and I just want the explaination of the second ‘can“ in grammar

Bad Luck Recently I have lost many things in my school, even sometimes I reckon it is done by a little elf as it happen in fairies. I look for them such as my cup, my meal card(furtunately there is little money in it, or I will be bankrupt.) and my student identificate. I am annoyed by these trifles. As a bad habit, carelessness is a bad habit and ought to be modified. Not only in my study but also in my daily life.

I feel no Concern from my Family Today is that my father's sister's daughter the first day of school. but I feel a bit , sort of..., well, I don't know how to say, maybe a bit envious because she is thiner tahn me and I am a little fat, besides I teach her for two months under my grandfather' demand but they still ignore me when she knows she get a good grade. Actually, at the beginning , I am not willing to teach her because I have my own plan and her sudden appearance and demands really disturb me. however, if I don't teach her, my grandfather will argue with me and turn very angry, consequantly, his Hypertension will burst out. I don't want to see that so I have to obey his demands, while my plan is broken down. I really tell her many things by using understandable words for her and ask her some questions that I think it diffcult to her. I teach her math and English. In fact, she attends extra math class in her math teacher house but she still has many questions. I ask her why not ask her teacher. she say she has asked her teacher but she still don't know it.Yeah, my extra job is helping her solve math problems. when I teach her, I sometimes tthink about my past: I have no extra help from others and no one tell me I should lose weight and I am a bit short, everyone just think I am a wreak. When I enter college, I become more active in minds. At least, I succeed in losing ten killgram fatt, and when I put on the pants that I can't wear before , I find it still leaft much the waist now. I really feel I have succeeded. I also learn much more English than before with a correct plan. Finally, when she get good grade and I finish my work, they don't talk with me and care about me again. I feel i am abandoned and used up, like a old battery. So I feel sad and make my mind to do my own things and then I will not help them(those selfish guys) ever after. I think if I fail they will not help me and more bad, they even ridicule me. I consider it a most important class, good grade don't mean anything, in effect, metal strength and great spirit is nothing less than what we should value.

My cat bear four Little Cats About a month ago, my cat born four little cats. By chance, I see the process of bearing. My uncle told me that the white cat, we call it Xiao Bai(In Chinese it means little white),had been pregenant for about three months. And I can see its offsprings this time because it born three cute cats last time. At around 1:30 pm, it began to find a clean and dim place to bear. therefore, we prepared a big box , then it should stand in it and to my surprise, the little cat was being born. I think at least , she should lie down. With its Placenta, Xiao Bai born its first baby smoothly. Then she lied in the box and began to shout, I know her pain, because she never shout as this before. then I go out to work as a tutor. When I am back, I see the four little offsprings, and Xiao Bai was licking them and cut off the Umbilical cord. Now these cats has its fur and look remarkblely cute as Xiao Bai (because it behave like a gentle princess with big eyes that they can vary with its moods. when she feel happy she becomes small and cute, if the mood turns bad, her eyes change into very big and fierce as if we must respect its mood. yeah, she is so hororable.)
