Because he was ill.3）My stomach hurts because I have eaten too many apples.4）-Why do you love her? -Because she is kind.5）He walked to the company because his bike was broken.6) Since I know very little Japanese, I cant catch what you said.7) As Mingming was not ready, we went without him.8) Since the outbreak of the Ebola in West Africa, many people are afraid to travel to Africa.二、合作探究：合作探究一：1. Check the answers.2. Lead-inAsk the question “why do you come to school?”3. Presentation合作探究二：A. Giving reasons with because1) because语气最强，表示直接原因，回答why的问题。通常放在主句之后，可单独使用。 如：Why do we learn English? We learn it because we want to have a better future.2) because可引导表语从句等。(1) It is because youre eating too much.(2) Have you ever walked into a room and felt relaxed? It could be because the walls were painted blue.3) because of 也可表达直接的原因，只不过其后接名词、代词或动名词。(1) He cant come because of his illness. (2) He is here because of you.4) because习惯上不与so连用汉语习惯上说“因为所以”，但英语习惯上却不能将 so与because 连用：因为我病了半年，所以把工作丢了。误：Because I was ill for six months, so I lost my job. 正：Because I was ill for six months, I lost my job.正：I was ill for six months, so I lost my job.合作探究三：B. Giving reasons with since and assince侧重主句，意思是“既然；由于；因为”，表示已知的、显然的理由，since 比as语气稍强，且比as略微正式，它们引导的从句通常放在主句之前，有时也放在主句之后。不表示直接原因。Since可用于省略句，而其他连词不行。（见例2）1. Since everyone is here, lets start2. Since so, I have nothing to say.3. Since you are wrong, you should say sorry.as 鉴于主从并重，从句说原因，主句说结果 。1. As it is late. I must go 2. As you were not there, I left a message.as和since的用法大体相同，表示附带说明的“双方已知的原因”或者理由不是很重要，但语气更弱，没有since正式，常译为“由于，鉴于”。As it is raining, youd better take a taxi. 既然在下雨，你最好乘出租汽车。 As you are tired, you had better have a rest. 既然累了，你最好休息一下。 for 由于，表明附加理由（解释或推断），从句不放于句首,语气最弱。He must be ill, for he is absent today。It must have rained last night, for the ground is wet.三、当堂检测：1) 用as, since ,because, because of填空(1) Mary missed the train_ she arrived late.(2) It will rain, _ the sky is dark.(3) _ we live near the river, we can often go swimming in summer.(4) Why do you like English? _ its so interesting.(5) _ a good teacher, he worked very hard.(6) _ the heavy rain, we had to stay inside.(7) _ it is Sunday today, you dont need to get up early.(8) _you broke his glasses, you should say sorry to him.2) 根据汉语完成句子（1）我喜欢唱歌，因为它能使我快乐。I like singing_.(2) 由于她擅长舞蹈，她就为我们跳了一曲。_, she danced for us.(3) 由于她起迟了，她气喘吁吁赶到学校。_she got up late, she hurried to school _.(4) 因为他工作努力，他的老板对他很满意。_.(5) 王先生不能出国，因为他丢了护照。Mr Wang cannot go aboard _ he has lost his passport.(6) 由于我口渴，我想先喝点水。_I was thirsty, I wanted to have something to drink.(7) 因为他太忙，所以他没去开会。_ he was very busy, he didnt _ the meeting.(8) 既然大家都在这儿，咱们就开始讨论这个话题吧。_ everyone is here, lets _ _ the topic.(9) 由于我不擅长唱歌，我就没有参加歌舞表演。_ I was not good at singing, I didnt take part in the song and dance show.(10) 既然Tom病了，他今天就不跟我们去钓鱼了。_ Tom is ill, he is not going_ with us today.四、课后巩固：一、 选择题（ ）1.Why was he late for school? _ he got up too late.
