（7）When Darren finally pushed his way out, he noticed his friends were both out of sight.
（8）He didn』t raise his head until someone called him.

（11）While we were having fun exploring, I realized Darren was lost.
（12）What a special trip!
二、重難點知識講解
1．How about exploring the Ming Tombs?
[譯文]去考察十三陵如何？
explore v.考察(某地區)，探險；勘察
e.g.He went out to explore.
他出去考察去了。
Have you really explored your nearest town?
你真的考察了離你們那兒最近的城鎮了嗎？
詞性變化：explorern.探險家，探測者
How about…?為提建議句型，about為介詞，後面跟動詞時要跟動詞的ing形式。
2．While you were enjoying your trip, I was busy preparing for my exams.
[譯文]你在愉快地遊玩時，我正忙著准備考試呢。
（1）這是一個由連詞while引導的時間狀語從句。當一個動作正在進行時，另一個動作也同時在發生，有對比的意味，一般主從句時態都用現在進行時或過去進行時。
e.g.I was doing my homework while Mom was cooking.
媽媽做飯時，我在做作業。
時間狀語從句可以放在前面也可以放在後面。
e.g.While Mom was cooking, I was doing my homework.
媽媽做飯時，我在做作業。
需要注意的是：從句在前面時，主從句之間要用逗號隔開。
（2）be busy doing…意為「忙於做……」。
e.g.He is busy finding a job these days.
這幾天他都忙著找工作。
He was soon busy reading his English book .
他很快就忙著閱讀他的英語課本了。
Everyone here is busy getting ready for Christmas .
這兒每一個人都在忙著為聖誕節作好准備。
be busy with也表示「忙於做某事」，但後面只能接名詞，不能接v.-ing形式。
e.g.He is busy mending his bike .
＝He is busy with his bike .
他正忙著修自行車。
3．You bet!
[譯文]當然！
You bet!表示「當然，的確」。
e.g.— Are you nervous? 你緊張嗎？
— You bet! 這還用說？
4．It would be great fun.
[譯文]那會很有趣。
would再此意為「一定會；就會」，是情態動詞，後接動詞原形表示猜測。
e.g.She would look nice with short hair.
她留短發會很好看。
That would be very interesting.
那一定會很有趣。
5．In the old days, only the emperors could ride horses through it.
[譯文]在過去，只有皇帝可以騎馬通過此門。
（1）in the old days意為「在古代」，days意為「時代，時期，時候」，需用復數形式。
e.g.in my school days 在我讀書的時代
（2）through為介詞，有「通過，經過」之意，不能作謂語，必須和動詞連用，同across。但across多指從物體表面穿過，而through用於從物體內部穿過。
e.g.The river goes through the city.
那條河流經這個城市。
go across the road=cross the road過馬路
6．They surveyed the area to make sure their tombs faced south and had mountains at the back.
[譯文]他們仔細勘測了整個區域，確保這些陵墓是坐北朝南， 而且背靠群山。
（1）make sure意為「確保，弄清楚」。
e.g.Make sure all the windows are closed before you leave.
離開之前，確保所有的窗戶都關上了。
（2）face在這里用作動詞，意為「面對，面向」。
e.g.My house faces the park.
我的房子面對公園。
7．They are at the foot of the Tianshou Mountains, in the northwest of Beijing.
[譯文]它們在天壽山腳下，位於北京西北部。
（1）英語中的方位
注意：英語中東南、東北、西南、西北的表達分別是southeast，northeast，southwest和northwest。
（2）in，on，to表示方位的區別
①「in the+方位詞+of…」用於在某一范圍內的地區。
e.g.Beijing is in the north of China.
北京在中國北部。(北京在中國范圍內)
②「on the+方位詞+of...」用於相互接壤且互不管轄的兩個地區。
e.g.Guangdong is on the south of Hunan.
廣東在湖南南邊。
③「to the+方位詞+of...」用於互不接壤且互不管轄的兩個地區。
e.g.The swimming pool is to the west of the house.
游泳池在房子的西邊(不接壤)。
總結：in表示在某一地區之內的方位（屬於該范圍）。on表示與某一地區的毗鄰關系。to表示在某一地區之外的某方位（不屬於該范圍）。它們所表示的位置關系恰似數學中圓的「包含（in）、相離（to）、相切（on）」關系。
8．After they parked their bikes, they walked through the passage into Dingling and were surprised at the wonders.
[譯文]他們停好自行車後，穿過通道走進定陵，對那裡的奇觀感到很驚奇。
be surprised at…意為「對……感到驚奇」。
e.g.He is surprised at dragons.

be surprised to do…意為「驚奇地(做)……」。

e.g.Where is the sense of wonder we felt when we were younger?
我們小時候的驚奇感哪裡去了？
the Seven Wonders of the World 世界七大奇跡
wonder還可以用作動詞，意為「對……疑惑，感到驚奇；想知道」。
e.g.I wonder what we can do to help Lily.
我想知道我們怎樣做才能幫助莉莉。
wonderful是在wonder後加-ful構成的形容詞，意為「了不起的，美妙的」。
e.g.It was a wonderful place for a picnic.
這是野餐的絕佳地點。
9．While the crowd was pushing him in all directions, someone stepped on Darren』s toes.
[譯文]當人群從四面八方擠來時，有人踩到了Darren的腳指頭。
（1）step on sth.意為「踏/踩某物」。
e.g.Don』t step on the flowers and grass.
不要踐踏花草。
（2）push此處為「擠來擠去，推推搡搡」之意。
e.g.People were pushing to get to the front.
人們推推搡搡，向前面擠。
（3）direction為名詞，意為「方向」，in the direction of...意為「朝……方向」。in one』s direction意為「朝著某人的方向」。
e.g.In which direction are you going, north or south?
你准備往哪個方向走？向北還是向南？
10．When Darren finally pushed his way out, he noticed his friends were both out of sight. He was too frightened to know what to do.
[譯文]當達倫最後（從人群中）擠出來時，發現他的兩個朋友都不見了。他很害怕，不知道該怎麼辦。
（1）out of sight意為「看不見」。
e.g.The house was out of sight behind a wall.
房子被牆遮住看不見了。
Keep out of my sight.
不要讓我看見你。
（2）too frightened to know what to do意為「很害怕，不知道該怎麼辦」。too… to… 意為「太……而不能……，太……以至於不……」，表達否定意義。too後接形容詞或副詞，to後接動詞原形，too… to…能用so… that…或enough to替換。
e.g.He is too excited to say a word.
=He is so excited that he can』t say a word.
他太激動以至於說不出話來。
The child is too young to go to school.
這孩子年齡太小而不能去上學。
=The child is not old enough to go to school.
（注意此時的形容詞為too...to結構中形容詞的反義詞。）
=The child is so young that he can』t go to school.
11．He didn』t raise his head until someone called him.
[譯文]直到有人喊他他才抬起頭。
（1）not… until…意為「直到……才……」，引導時間狀語從句。
e.g.He didn』t go to bed until he finished his work.
直到做完作業他才上床睡覺。
（2）raise意為「籌集；提起；使升高；飼養」，及物動詞，能直接跟賓語。
e.g. raise money 籌錢
raise one』s head抬頭
raise one』s hand舉手
12．While we were having fun exploring, I realized Darren was lost.
[譯文]正當我們興致勃勃地考察時，我意識到達倫不見了。
have fun exploring表示「有趣地考察、興致勃勃地考察」。
have fun (in) doing sth.表示「從……中獲得樂趣」。
e.g.He has fun playing soccer.
他從踢球中獲得樂趣。
三、語法點撥——時間狀語從句
時間狀語從句是表示時間關系的從句。在時間狀語從句中，要注意時態一致。一般情況下，主句是一般將來時，從句用一般現在時；主句是過去時態，從句也要相應用過去的時態。引導時間狀語從句的連接詞有：when，while，as，before，after，since，till，until等。
根據意義和主從句之間的時間關系，可分類如下：
1．表示同時性，即主從句的謂語動作同時發生或幾乎同時發生。其連接詞有：when(當……的時候)，while(……的時候)，as(當……的時候)，as soon as(一……就)，once(一……就)等。
e.g.Mary cut her finger when she was making a dress.
瑪麗在做衣服時，割傷了手。
I』ll ring you up as soon as I arrive in Beijing.
我一到北京就給你打電話。
Once he arrives we can start.
他一來我們就可以動身。
As she was reading the newspaper, grandma fell asleep.
當她在看報紙時，奶奶睡著了。
Work while you work. Play while you play.
該工作時工作，該玩時玩。
2．表示先後，即主句的謂語動作發生在從句之前或之後。主要的連接詞有：after(在……之後)，before(在……之前)等。
e.g.After the children had gone to bed, she began to prepare her lessons.
孩子們睡覺後她開始備課。
He had learned English for three years before he went to London.
他去倫敦之前已學了三年英語。
3．表示持續或瞬間性，主要連接詞有：since(自從)，ever since(自從)，until(直到……才/止)，till(直到……才/為止)等。
e.g.It is just a week since we arrived here.
我們到這剛一星期。
Ten years has passed since we left our school.
自從我們畢業以來已過了10年。
Don』t get off the bus until it has stopped.
直到車停了再下車。
He waited for his father until (till) it was twelve o』clock.
他等他父親等到12點。
註：
（1）until用於肯定句中，表示主句的動作一直持續到從句動作發生或狀態出現時為止。一般意為「……直到……為止」。這種用法中，主句的謂語動詞必須是持續性動詞(非瞬間動詞)。如：live，wait，last，love，like，stay，work，continue等。
（2）until用於否定句中，表示主句的動作在從句的動作發生之前尚未發生，或者說主句的動作在從句的動作發生之後才開始。此句型為「not… until…直到……才……」，此時，主句的謂語動詞可以是非持續性動詞。
希望對你有幫助謝謝！望採納！
