13、试2）a lot of (=lots of) 大量，许多；既能修饰可数名词，又能修饰不可数名词。a lot of一般用于口语肯定句中，在否定句和疑问句中则用many或much。例如：I picked lots of flowers. 我摘了许多花。Thanks a lot. 多谢。A lot of energy was wasted. 大量的能源被浪费掉了。There isnt much tea in the cup. 杯子里茶水不多了。Do you have many questions to ask? 你有许多问题要问吗?3）ten to eleven times a week是名词性短语

15、一健康的习惯。1）这是一个含有让步状语从句的主从复合句，although表示“虽然”、“但是”引导让步状语从句通常置于句子后部，也可置于句子前部。需要注意的是，从句中用了though或although，主句中就不能再用but，这和汉语翻译“虽然但是”不一样。例如：He went out，though it was raining. 尽管下雨他还是出去了。Although they started early，they arrived late. 虽然他们动身很早，但是到的却很晚。2）句中强调词do用来加强从句中谓语动词的语气，这种用法通常用于符合以下两个条件的句子中；句子是肯定句；句子中的谓语

16、动词是一般现在时或一般过去时，分别用do，does或did来加强其语气。do的强调用法在译成汉语时，可依照各种情况译成“是”、“的确”、“确实”等。例如：Do tell me all about it. 请告诉我一切吧。You do look nice today. 你今天看上去真漂亮。She said she would come and did come. 她说她要来，她果真来了。4. Fill in the blanks with the words given. 用所给单词填空。这是一个祈使句，fill in表示“填写”、“填上”是固定的动词短语。例如：Please fill in t

17、his form请填这张表。Please fill your name and telephone number in the blank。请把你的名字和电话号码填在空格处。given是过去分词作后置定语，修饰words。words与give之间是被动关系，所以应用过去分词作定语。例如：This is a book written by a peasant这是一本农民写的书。【词语辨析】1. good, fine, well与nice这几个形容词都有“好”的意思。（1）good是通用词，可以表示各种品质方面的优异，从美学到道德规范几乎都可以使用。Its an old film, but its

19、而且初学者不易掌握。These ice-creams are nice. 这些冰淇淋真好。Hes a very nice man. We shall miss him. 他是个很好的人。我们会想念他的。She is a very nice girl. 她是个很好的姑娘。注意：nice and = very, ratherIts nice and warm in here. 这里面很暖和。2. home, house和family三者都可表示“家”，但所指不同。（1）house一般指所居住的建筑物，即“房子；住宅。”His house was burned in a big fire. 他的家在

20、一场大火中被烧了。（2）family着重指家庭的成员。如：My family are all fond of music. 我们一家人都喜欢音乐。（3）而home则指某人出生及生活的那个环境，包括住处及家人。如：He left home at the age of 18. 他十八岁离开了家。homework 家庭作业；课外作业He usually does his homework after school. 他通常放学后做作业。hometown 家乡；故乡Wheres your hometown? 你的家乡在哪里？Its in Suzhou. 在苏州。homeland 祖国；本国I love

22、maybe连在一起是副词，意为“可能；也许；大概”，在句中作状语，通常置于句首，也可以放在谓语动词之前。may be分写是“情态动词+动词原形”的形式，意为“可能是；也许是”，在句中作谓语。试比较：Maybe he will come, maybe he wont. 他也许来，也许不来。Is that true? 那是真的吗？Maybe, Im not sure. 也许（可能）是，我说不准。He may be eighteen. 他可能18岁了。Maybe your book is at home. 也许你的书在家里。The book may be in the desk. 那本书可能在课桌里

23、。5. although与thoughalthough和though作连词用，意为“尽管；虽然”，二者可以通用。如：Although / Though they are so poor, they have enough to eat.他们虽然很穷，食物还是够吃的。在一个句子里，用了although或though，就不能用but，用了but，则不能使用although或though，即“虽然但是”不见面，但可用yet。如：Although (Thought) it was very cold, (yet) he went out without an overcoat. = It was ve

24、ry cold, but he went out without an overcoat.尽管外面很冷，但他没有穿大衣就出去了。【语法知识聚焦】一般现在时The Simple Present Tense 一般现在时表示现在的状态He is twelve. 他十二岁。They are at home. 他们在家。表示经常性或习惯性的动作I go to school at seven every day.He plays soccer on Sundays.表示主语具备的性格和能力等She likes apples.They speak Japanese.She is of medium buil
