14．---Did you go to Grace's party？
---No，because I_____．（　　）
A．am not invitedB．wasn't invitedC．won't inviteD．didn't invite

分析 --你去參加Grace的聚會(huì)了嗎？
--沒(méi)有，因?yàn)槲覜](méi)有受到邀請(qǐng)．

解答 答案：B．
首先根據(jù)語(yǔ)境推測(cè)答語(yǔ)的句意是"沒(méi)有，因?yàn)槲覜](méi)有受到邀請(qǐng)．"，判斷句子中的謂語(yǔ)動(dòng)詞用一般過(guò)去時(shí)，主語(yǔ) I是動(dòng)作 invite的承受者 所以用被動(dòng)語(yǔ)態(tài)，一般過(guò)去時(shí)被動(dòng)語(yǔ)態(tài)的構(gòu)成是：主語(yǔ)+was/were+動(dòng)詞的過(guò)去分詞，變否定句在be后面直接加not，故選B．

點(diǎn)評(píng) 本題考查時(shí)態(tài)和語(yǔ)態(tài)．每個(gè)時(shí)態(tài)都有標(biāo)志詞，熟記這些標(biāo)志詞是做題的關(guān)鍵．在沒(méi)有時(shí)間狀語(yǔ)的情況下可以根據(jù)語(yǔ)境來(lái)對(duì)時(shí)態(tài)做出判斷．判斷語(yǔ)態(tài)的關(guān)鍵則是觀察主語(yǔ)是謂語(yǔ)動(dòng)詞的執(zhí)行者還是承受者．

2．Fish have ears．Really．They're quite small and have no opening to the outside world carrying sound through the body．For the past seven years，Simon Thorrold，a university professor，has been examining fish ears，small round ear bones called otoliths．
   As fish grow，so do their otoliths．Each day，their otoliths gain a ring of calcium carbonate （碳酸鈣）．
By looking through a microscope （顯微鏡） and counting （數(shù)） these rings，Thorrold can determine the 
exact age of a young fish．As a fish gets older，its otoliths no longer get daily rings．Instead，they get yearly rings，which can also be counted，giving information about the fish's age，just like the growth rings of a tree．
    Ring counting is nothing new to fish scientists．But Thorrold has turned to a new direction．They'reexamining the chemical elements （元素） of each otolith ring．
    The daily ring gives us the time，but chemistry tells us about the environment in which the fish swam on 
any given day．These elements tell us about the chemistry of the water that the fish was in．It also says something about water temperature，which determines how much of these elements will gather within each otolith ring．
   Thorrold can tell，for example，if a fish spent time in the open ocean before entering the less salty water 
of coastal areas．He can basically tell where fish are spending their time at any given stage of history．
   In the case of the Atlantic croaker，a popular saltwater food fish，Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast，a journey of many hundreds of miles．
   This is important to managers in the fish industry，who know nearly nothing about the whereabouts （行蹤） of the young fish for most food fish in the ocean．Eager to learn about his technology，fish scientists 
are now lending Thorrold their ears．

57．What can we learn about fish ears from the text？B
A．They are small soft rings．
B．They are not seen from the outside．
C．They are openings only on food fish．
D．They are not used to receive sound．
58．Why does the writer compare the fish to trees？D
A．Trees gain a growth ring each day．
B．Trees also have otoliths．
C．Their growth rings are very small．
D．They both have growth rings．
59．Why is it important to study the chemistry of otolith rings？C
A．The elements of the otoliths can tell the history of the sea．
B．Chemical contents （含量） of otoliths can tell how fast fish can swim．
C．We can know more about fish and their living environment．
D．Scientists can know exactly how old a fish is．
60．How would you understand"fish scientists are now lending their ears"？A
A．They are very interested in Thorrold's research findings．
B．They want to know where they can find fish．
C．They lend their fish for chemical studies．
D．They wonder if Thorrold can find growth rings from their ears．

1．Chinatown is the name given to an area in the middle of London．It is just between Leicester Square and Shaftsbury Avenue．Gerrard Street is at the center and is the most important street in the area．There is a large Chinese community（社區(qū)） with a lot of Chinese restaurants，Chinese supermarkets and shops in this street．
In the 1950s，it was a poor area and everything was very cheap．At the same time，the world rice market changed and thousands of farm workers in Hong Kong lost their jobs．They began arriving in London to look for work．They found jobs in the restaurants in this area．Many British people like Chinese food，and the restaurants were popular．
These restaurant workers often worked 17hours a day and had no time to learn English．As more Chinese arrived，more shops and businesses grew up．Wives came and joined their husbands and children came and joined their fathers．The community grew，and Chinatown was born．
In the 1970s and 1980s，British-born Chinese started to have a better education and this brought economic（經(jīng)濟(jì)的） success to the area．Many families moved out of Chinatown，and there was more space for businesses．Gerrard Street become a street only for visitors and was soon a popular place for tourists．
Now everyone knows about London's Chinatown．During the Chinese New Year，the streets are seen with flags and thousands of Chinese go into the streets．For most of the year，though，Londoners and tourists go there mainly for the food in the Chinese restaurants．The best restaurants are the ones where the Chinese eat．

91．Is this Chinatown in the middle of London？
Yes，it is．
92．Was the area rich or poor in the 1950s？
It was poor．
93．Why did the restaurant workers have no time to learn English？
Because they often worked 17 hours a day．
94．When did British-born Chinese start to have a better education？
Theystarted to have a better education in the 1970s and 1980s
95．What does the passage mainly tell us？
It tells the development history about Chinatown in London．
