A very important world problem-in fact, I am inclined(傾向) to say it is the most important of all the great world problems which face us at the present time-is the rapidly increasing pressure of population on land and on land resources.

It is not so much the actual population of the world but its rate of increase which is important. It works out to be about 1.6 percent per annual net increase. In terms of numbers this means something like forty to fifty-five million additional people every year. Canada has a population of twenty million-rather less than six month's climb in world population. There are ten million people in Australia. So, it takes the world less than three months to add to itself a population. Let us take our own crowded country-England and Wales: forty-five to fifty million people-just about a year's supply.

By this time tomorrow, and every day, there will be added to the earth about 120,000 extra people-just about the population of the city of York.

Here I am not talking about birth rate. This is net increase. To give you some idea of birth rate, look at the seconds hand of your watch. Every second three babies are born somewhere in the world. Another baby! You cannot speak quickly enough to keep pace with the birth rate.

This enormous increase of population will create immense problems. By 2020 unless something desperate happens, there will be as many as seven billion people on the surface of the earth! So this is a problem which you are going to see in your lifetime.

1. 解析:選C。細(xì)節(jié)理解題。從文章第一段可知,人口對土地及其資源的不斷快速增長的壓力為最重要的世界問題。

2. 解析:選D。推理判斷題。由文章第二段最后一句“Let us take our own crowded country-England and Wales”意為“讓我們說一下我們自己擁擠的國家——英格蘭和威爾士”可知。

3. 解析:選A。細(xì)節(jié)理解題。由文章第二段倒數(shù)第二句“因此,地球上的人類花不到三個月的時間就可以增加一個澳大利亞的人口!笨芍渲校發(fā)ess than three months”與“about three months”意思相近。

4. 解析:選D。推理判斷題。由文章第四段第四句“Every second three babies are born somewhere in the world”可推知,每小時有10,800個嬰兒出生。

5. 解析:選D。推理判斷題。作者以不同國家的人口為例來強(qiáng)調(diào)世界人口的高增長率。

科目:高中英語 來源: 題型:閱讀理解

     The other day, my friend Jane was invited to a 40th birthday party. The time printed on the invitation was 7.30pm. Jane went off with her husband, expecting a merry evening of wine, food, and song.

By 9.45, everybody was having great fun, but no food had appeared. Jane and David were restless. Other guests began whispering that they, too, were starving. But no one wanted to leave, just in case some food was about to appear. By 11.00, there was still no food, and everyone was completely off their heads. Jane and David left hungry and angry.

Their experience suggests that the words an the printed invitations need to be made clearer. Everyone reads and understands the invitations differently. Most of us would agree that 6.30 -8.30pm means drinks only, go out to dinner afterwards; 8.00pm or 8.30pm means possible dinner, but 9.30pm and any time thereafter means no food, oat beforehand, roll up late.

But this is not always the case. If asked to a students' party at 6.30pm, it is normal for guests not to appear before midnight, if at all, and no one cares. Being the first to arrive - looking eager - is social death. When my mother is asked to a party for 6.30, she likes to be them, if not on lime, then no later than seven. My age group (late thirties) falls somewhere between the two, but because we still think we're  young, we're probably closer to student-time than grown-up time.

The accepted custom at present is confusing (混亂的), sometimes annoying, and it often means you may go home hungry, but it does lend every party that precious element (成分) of surprise.

68. The underlined words "off their heads" probably mean______.

              A. tired            B. crazy                C. curious                D. hopeless

69. Jane and David' s story is used to show that______ .

              A. petty-goer8 usually get hungry at parties

              B. party invitations can be confusing

             C. people should ask for food at parties

             D. birthday parties for middle-aged people are dull

70. For some young people, arriving on time for a students' party will probably be considered_______.

    A. very difficult         B. particularly thoughtful

              C. friendly and polite                     D. socially unacceptable

71. According to the writer, people in their late thirties_______.

              A. are likely to arrive late for a party

             B. care little about the party time

             C. haven' t really grown up yet

             D. like surprises at parties

72. What is the general idea of the text?     

             A. It' s safe to arrive late just when food is served.

             B. It' s wise to eat something before going to a party.

             C. It' s important to follow social rules of party-going.

             D. It' s necessary to read invitations carefully.
