"是强调句型,强调的是句子的主语my sister;where it begins和where it ends都是宾语从句,分别作介词from和to的宾语。整个句子可以翻译成"首先想到要沿湄公河从源头到终点骑自行车旅游的就是我的姐姐。"这里需要注意的是,强调句型可以用来强调除谓语以外的任何成分,如果被强调部分是表示人的名词或代词,可用that,也可以用who,其他情况下一律用that。it was i who/that saw mary in the street this afternoon.

(定语从句)表示时间或地点的名词前有介词时,一般为强调句型;前面没有介词时,多为定语从句。但应注意,有些表示时间的名词或短语在作状语时本身不需要加介词,也应视为强调句型。it was yesterday/last week that we chatted a lot on line.昨天/上周我们在网上聊了许多。it was not until she got home______________ jennifer realized she had lost her keys.a. when  b. that  c. where  d. before答案:b2. although she didn’t know the best way of getting to places, she insisted that we find the source of the river and begin our journey there.这里的although she didn’t know the best way of getting to places是让步状语从句;that we find the source of the river and begin our journey there是宾语从句,用的是虚拟语气。整个句子可以翻译成"尽管她对到某些地方的最佳路线并不清楚,她却坚持我们要找到河的源头,并从那里开始我们的行程。"动词insist在表示"坚持某人应该……"时,后面的宾语从句应该使用虚拟语气,即should+动词原形或省略should直接用动词原形。they insisted that he (should)be present at the ceremony.他们坚持认为他应该出席庆典仪式。mother insisted that a girl (should)not go out alone at night.妈妈坚持认为女孩子不应该晚上一个人出去。3. she gave me a determined look—the kind that said she wouldn’t change her mind.这里的the kind是a look的同位语,that said she wouldn’t change her mind 是that引导的定语从句。determined在句中的意思是"坚决的,坚定的";say的意思是"指明,表明"。整个句子可以翻译成"她给了我一个坚定的眼神——这种眼神表明她是不会改变主意的"。she is a very determined woman who always gets what she wants.她是一名意志非常坚定的妇女,总是会得到她想要的东西。the clock on the wall said a quarter to ten.墙上的钟表明差一刻十点。4. once she has made up her mind, nothing can change it.这里的once she has made up her mind是状语从句,相当于when she has made up her mind。once在这里用作连词,表示as soon as一旦;一……就……。整个句子可以翻译成"她一旦下了决心,什么也不能使她改变。"once you understand the rule, you will have no difficulty.一旦明白了这条规则,你就再也没有困难了。what will we do once the money is used up?钱一旦用完,我们该怎么办?once printed, this dictionary will be very popular!一旦出版,这本词典将会非常畅销!once adv.1)(for)one time一次2)at some time in the past一度;曾经3)all at once:suddenly突然once a year, a race is held for old cars.每年举行一次旧式小汽车比赛。it once seemed inconceivable to everyone that men should travel to the moon.人们一度认为,人飞上月球似乎是不可想象的。all at once the door opened.门突然开了。______________ environmental damage is done, it takes many years for the ecosystem (生态系统)to recover.a. even if  b. if only  c. while  d. once答案:d5. it becomes rapids as it passes through deep valleys, traveling across western yunnan province.这里的as it passes through deep valleys是时间状语从句,traveling across western yunnan province是现在分词作伴随状语,整个句子可以翻译成"它穿过深谷时就变成了激流,流经云南西部。"they came to the street, looking for the lost dog.他们来到街上,寻找丢失的狗。the boys and girls went to school, singing and dancing all the way.孩子们走在上学的路上,载歌载舞。through&across:through和across都有"经过""穿过"的意思,但二者又有区别。through是指在物体内部穿过,它的含义和in有关;across是指在物体表面上经过,它的含义和on有关。we walked through the market to the truck park.我们穿过市场来到了卡车停车场。they walked across the playground and disappeared in the dark.他们穿过操场,消失在黑暗中。 step 6 consolidationtest for important language points. show the following on the screen.translate the following sentences.1. 去北京的单程火车票价是多少?2. 我怎么才能使你相信我的诚实?3. 他坚定的表情告诉我们,谁都无法改变他的想法。4. 妈妈坚持说我累了,应该在10:00前上床睡觉。5. 小英雄刘胡兰宁死不屈。6. it was only when i reread these poems recently that i began to appreciate their beauty.7. was it tom who helped you with your homework?8. the old man died, leaving his wife and children a lot of money.9. once you talk to her, you’ll know she is a warm-hearted person.10. his advice determined me to delay no more.several minutes later, check the answers with the whole class. deal with any problems students meet if necessary.suggested answers:1. what’s the one-way train fare to beijing?2. how can i persuade you that i am honest/of my honesty?3. his determined look told us that no one could make him change his mind at all.4. mother insisted that i was tired and that i should go to bed before 10:00 o’clock.5. the little heroine, liu hulan would rather die than give in.6. 我是最近重读这些诗时,才欣赏到它们的美。7. 是汤姆帮你完成家庭作业的吗?8. 老人过世了,留给他妻子和孩子们一大笔钱。9. 一旦你和她谈谈,你就知道她是一个热心人。10. 他的劝告使我决定不再拖延。 step 7 workbookdo the exercises in using words and expressions on page 56. step 8 homework1. finish off the workbook exercises. write down exercise 3 in the exercise book.2. learn the new words and expressions by heart.设计方案(二) step 1 revision1. check the homework exercises.2. ask some students to tell something about wang kun and wang wei’s bike trip or the mekong river. step 2 reading and practice1. get the students to read the reading passage again to underline all the new words and useful expressions or collocations in the passage.2. do the exercises in discovering useful words and expressions on page 20. step 3 checkingdeal with the problems the students meet while checking the answers. step 4 language pointsexplain and practice some important new words and expressions. step 5 sentence focusanalyze some difficult long sentences and practice some important language points in them. step 6 consolidationtest for important language points. step 7 workbookdo the exercises in using words and expressions on page 56. step 8 homework1. finish off the workbook exercises. write down exercise 3 in the exercise book.2. learn the new words and expressions by heart.
