7．Potatoes are very popular today．But in the past this was not true．Potatoes grew in South America 5，000 years ago．But they only became popular in other places 200 years ago．
In the 16th century，the Spanish took the potato from South America to Europe．But the people didn't like this strange vegetable．Some people thought that their skins would look like the skin of the plant if they ate the potato．So they only ate the leaves．This made them sick because there is poison （毒藥） in the leaves．
In the 1800s，people started to eat potatoes．Potatoes became the main food in Ireland．Then something unlucky happened．In 1845，a disease killed all the potatoes in Ireland．Two million people died of hunger．
Today each country has its potato dish．Germans eat potato salad，and the USA has the baked potato．Of course，the French invented French fries．
Fill in the blanks according to the passage．Only one word for each blank．

分析 本文主要講述人們對(duì)馬鈴薯的認(rèn)識(shí)過(guò)程．16世紀(jì)，西班牙人把馬鈴薯從南美洲帶到歐洲．當(dāng)時(shí)歐洲人并不喜歡這個(gè)奇特的蔬菜．19世紀(jì)，人們開(kāi)始吃馬鈴薯．在愛(ài)爾蘭，馬鈴薯成了主食．今天，各個(gè)國(guó)家都有各自的馬鈴薯佳肴．

解答 76．grown細(xì)節(jié)理解題．根據(jù)第一段Potatoes grew in South America 5，000 years ago．的描述可知，5000年前馬鈴薯被種植于南美．結(jié)合語(yǔ)境可知應(yīng)用被動(dòng)語(yǔ)態(tài)，故填：grown．
77．until細(xì)節(jié)理解題．根據(jù)第一段they only became popular in other places 200 years ago．的描述可知，馬鈴薯直到兩百年前才開(kāi)始在各地受到歡迎．結(jié)合語(yǔ)境可知應(yīng)填：until．
78．instead細(xì)節(jié)理解題．根據(jù)下文people were badly ill because of the poison in the leaves．的描述可知，當(dāng)時(shí)人們只吃它的葉子，而不是吃馬鈴薯．結(jié)合語(yǔ)境可知應(yīng)填：instead，instead of而不是．
79．However細(xì)節(jié)理解題．根據(jù)上下文的描述可知，19世紀(jì)，人們開(kāi)始吃馬鈴薯．然而，由于全愛(ài)爾蘭的馬鈴薯受到了侵害，有兩百萬(wàn)人因此餓死．結(jié)合語(yǔ)境可知，這里存在轉(zhuǎn)折關(guān)系，故填：However．
80．kinds細(xì)節(jié)理解題．根據(jù)第三段each country has its potato dish．的描述可知，現(xiàn)在世界上有各種各樣的馬鈴薯佳肴．結(jié)合用酒精可知應(yīng)填：kinds．

點(diǎn)評(píng) 做題時(shí)首先要仔細(xì)閱讀短文，掌握大意，然后結(jié)合具體的題目，找出相關(guān)信息，就可以確定正確答案．

We all see and hear about extraordinary(優(yōu)秀的) people around us and wonder why we can’t be more like them. It’s not the big things that make someone extraordinary. It’s the small things. They become extraordinary by making a difference in someone’s life. Here are some of the things extraordinary people do every day:

Praise(表?yè)P(yáng))someone. It can make the others feel great about themselves. A compliment can have a positive impact(影響) on their lives. Your team or family will love you for it.

It’s OK to admit(承認(rèn)) you were wrong. You will not only gain the respect of your team mates, but you will also gain credibility(信用).

When you need help, don’t be shy or stop yourself. Everyone needs a little help sometimes. When you ask for help, you receive help. You’re willing to listen; you also need support at times.

When you don’t understand how something works, let an expert show you. When you let someone teach you something, you are telling the person that you respect his talent, time and what he is talking about.

Sometimes it is very important to stay silent. Especially when you’re angry, process your emotions, think back to what happened, and then come to a decision about how to deal with it. Before you say anything, consider others’ feeling. Never be rude with words or actions.

1. In the passage, how many points about being an extraordinary person does the writer refer to?

15．The Age of Unreason
Charles Handy
In his book The Age of Unreason Professor Handy describes   the   dramatic changes that are taking place in our lives today and warns that we must adapt to these changes if we  want  to survive in the future．Handy believes that in the future less than 50% of the workforce will   be employed full-time by an organization．These full-time employees will be the qualified     professionals，technicians，and managers who are essential to an organization．Their working lives will be a lot more demanding than today，but in return they will be well-paid and they will retire earlier．The rest of the workforce will Be self-employed or will work part-time，providing organizations    with    the products and services they require on a contract basis．Handy  forecasts  a  big  increase in the number of working mothers in future and believes there will be a large number of unemployed．
Handy gives us plenty of figures to worry about．He estimates that by the year 2040，one person in five will retire，and one in ten will be over seventy-five years old．There will be one retiree to every three people of working age，and even more than that in countries such as Germany and Switzerland，where the proportion will be as much as one  to  two．Retirees will remain healthy and active for longer than they do today and many will live to be a hundred years old，a fact which leads Handy to suggest that the term retirement will no longer be appropriate．He suggests the third age is a more appropriate description，since it will be as important a part of our lives as the first age of learning and the second age of working are for us today．
69．Professor Handy wrote the book most probably toA
A．warn us of potential social problems in the future
B．predict the leading professions in the coming years
C．describe the effect of unemployment on society
D．suggest a better term for future retirement
70．According to Protcssor Handy，the future workforce willC
A．a(chǎn)dapt to the changes in retirement easily  B．be mainly self-employed
C．have fewer full-time workers than today  D．work on a contract basis
71．Prom the last paragraph，we learn that about 30 years from now，B
A．the number of retirees will double in many countries
B．a(chǎn)geing will be a common and serious problem
C.10% of the population will live to be 100years old
D．the third age will be the most important part of our lives．

2．How would we travel without maps？It would be a bit adventurous （冒險(xiǎn)的） to set off from Oxford University to go to London Bridge if there wasn't a map of the London Underground at each station．In fact，a lot of the early map-makers were adventurers and explorers，especially in the 15th and 16th centuries．
So what did people do before there were maps？Well，it was quite easy to use natural signs like mountains and rivers if you were travelling on foot or riding a horse．People took small boats down rivers and followed coastlines．And it was much more logical （合理的） to use time，not distance，to measure （計(jì)量） journeys：the next village is a three-hour ride，for example．
In fact，in the earliest maps，people didn't draw landmarks．They drew the stars．It was very easy to see the night sky and use it for navigation （航行）．The sky was a lot clearer before the light pollution from cities that we have today．When towns and cities were built，people drew road maps which gave correct distances and directions．
The London Underground was opened in 1863and it also used a road map style．But a man called Henry Beck realized that travelling by train wasn't the same as driving your car across London．Passengers only needed to know which stations to change at．His new design （設(shè)計(jì)） for the Underground map wasn't very popular with the train companies at first．But the passengers loved it and in 1933，700，000copies were printed．
These days，of course，you can ride a bike，drive a car or go through a forest and know where you are exactly，using a GPS．It's really difficult to get lost!
82．What was drawn in the earliest maps？A
A．Stars．B．Landmarks．
C．Cities and towns，D．Mountains and rivers．
83．When did road maps come out？D
A．Around 15th and 16th centuries．B．When people began to travel by train．
C．When people began to travel by sea．D．When cities and towns appeared．
84．Which of the following is true？B
A．A GPS helped people to travel long time ago．
B．Ancient people could travel on a horse without maps．
C．The sky was polluted by light before cities were built．
D．Henry Beck's map wasn't popular with the passengers．
85．What is the main idea of the passage？A
A．Maps have a long history．B．We never get lost these days．
C．We can't travel without maps．D．Henry Beck designed a new map．

16．A little boy invited his mother to attend （出席） his elementary school's first teacher-parent meeting．To the little boy's dismay （沮喪），his mother said she would go．This would be the first time that his classmates and teachers met his mother and he was embarrassed（尷尬的）by her appearance．There was a severe （嚴(yán)重的） scar （傷疤） that covered nearly the whole right side of her face．The boy never wanted to talk about why or how she got the scar．
At the meeting，the people were impressed （留下深刻的印象） by the kindness of his mother with the scar，but the little boy was still embarrassed and hid himself from everyone．However，he could hear clearly the conversation between his mother and the teacher．
"How did you get the scar on your face？"the teacher asked．

When the little boy heard this，he couldn't help running towards his mother with tears in his eyes．He hugged her and felt his mother was greater than anyone．He held her hand tightly for the rest of the day．
