14.Space travel is nothing new.The first spacecraft with a human was sent up into space in 1961.Since then,people have not only traveled to space,but many of them have also lived there in space stations for sometime.
The Soviet Union sent the first space station into space in 1971.this space station was called Salyut 1.Salyut 1was designed as a place where people could live while they observed space and did experiment.The first group of astronauts lived there for 23days.The Soviet Union went on to make seven more Salyut space stations.At about the same time,the United Stations built its own space station,called Skylab.
Astronauts visited and often lived in these space stations for a short time.However,it wasn't until the late 1980s when the Soviet Union sent the Mir space station that people began to live in space for a longer time.Mir stayed in space from 1989until 2001,when it was decided that the space station was too old and no longer safe to live in.
Living in space stations seems to be fun,but astronauts face many problems.One of them is food.All the meals on space stations are put together on Earth and sent there by space shuttle.Because the food has to last a long time (sometimes up to three months),a lot of it has to be stored in cans.The space station does not have a fridge,but it has a cool room to keep fruit and vegetables fresh.Astronauts also eat many other foods such as dried meat that do not need special care.
Without the help of gravity,sitting down to eat can be tough.Astronauts sometimes have to fix themselves to the wall while eating.They also have to be very careful so that food does not float away.

31.Which of the following has the closest meaning to the underlined word"observed"in Paragraph 2?C
A.Discovered      B.Checked      C.Watched         D.Fixed
32.What can we infer(推斷) from the passage?B
A.Astronauts can never have a chance to eat fresh food when they live in space stations.
B.The Soviet Union sent a total of 9space stations into space in the 1970s and 1980s.
C.Astronauts could live in the Mir space station for no more than three weeks.
D.Space travel has quite a long history of more than 60years.
33.What is the best title of this passage?D
A.Exploring Space   B.Space Travel   C.Living in Space   D.Space Stations.

分析 宇宙旅行不是什么新鮮事了.第一艘載人宇宙飛船在1961年送入太空.從那時(shí)起,人們不僅僅去太空旅游,他們中的許多人同時(shí)還住在太空一段時(shí)間.
蘇聯(lián)1971年發(fā)射了第一個(gè)空間站Salyut 1進(jìn)入了太空,Salyut 1設(shè)計(jì)成一個(gè)人們能居住的能觀察太空能做實(shí)驗(yàn)的地方.第一個(gè)宇航員小組在那住了23天.蘇聯(lián)繼續(xù)又建造了七個(gè)蘇聯(lián)空間站.同時(shí),美國(guó)也建立了自己的空間站,叫做Skylab.
宇航員在空間站參觀居住很短的時(shí)間,然而,直到19世紀(jì)80年代蘇聯(lián)發(fā)射Mir太空站,人們才開(kāi)始在那住更長(zhǎng)的時(shí)間.和平號(hào)空間站在太空從1989年待到2001年,當(dāng)這個(gè)空間站太舊了不能再安全的居住了的時(shí)候.
住在太空似乎很有趣,但是宇航員面臨著許多問(wèn)題,其中一個(gè)就是食物,在太空站所有的食物在地球上放在一起,然后由航天飛機(jī)送去太空站.因?yàn)槭澄镄枰3忠欢螘r(shí)間(有時(shí)候要保持三個(gè)月),其中的很多食物需要用罐頭儲(chǔ)存.太空站沒(méi)有冰箱,但是它有一間涼爽的屋子讓水果蔬菜保鮮.宇航員也吃其他的食物,例如風(fēng)干肉,不需要特別的保管.
沒(méi)有重力,坐下來(lái)吃東西是困難的,宇航員吃飯的時(shí)候有時(shí)候?qū)⒆约航壴趬ι希麄冞必須非常小心,那樣食物才不會(huì)漂走.

解答 31:答案:C.詞義理解題.結(jié)合Salyut 1was designed as a place where people could live while they observed space and did experiment聯(lián)系上下文,可知此處是說(shuō)在太空做實(shí)驗(yàn),觀察太空,故選C.
32:答案:B.推理判斷題.根據(jù)第二段The Soviet Union(前蘇聯(lián)) sent the first space station into space in 1971.…The Soviet Union went on to make seven more Salyut space stations.描述,可知建立了第一個(gè)太空站之后又建了七個(gè),it wasn't until the late 1980s when the Soviet Union sent the Mir space station that people began to live in space for a longer time在十九世紀(jì)八十年代又發(fā)射了一個(gè)和平號(hào)空間站,故一共9個(gè),可知選B.
33:答案:D.標(biāo)題判斷題.這篇短文主要描述了空間站的發(fā)展歷史和科研人員在空間站的工作生活情況.故選D.

點(diǎn)評(píng) 本文淺顯易懂,層次分明,學(xué)生很容易把握文章中心內(nèi)容.答題中注意帶著問(wèn)題閱讀短文,一般就能順利找出答題依據(jù).對(duì)于不能直接找到根據(jù)的問(wèn)題注意聯(lián)系上下文,根據(jù)短文中心總結(jié)出正確答案.

3.It is believed that the first chopsticks were developed over 5,000years ago in China.In the Spring and Autumn Period,copper(銅) and iron(鐵) chopsticks appeared.Then the lacquered(涂漆的) chopsticks came in Han Dynasty.Later gold and silver(銀色的) chopsticks followed.Today we have chopsticks made of different materials.The most expensive are made of part of tusks(長(zhǎng)牙) of elephants and the green stone(寶石).
In ancient times the rich used hard green stone or gold chopsticks to show their wealth(財(cái)富).It was said that silver chopsticks would turn black if they touched poisoned(有毒的) food (but we know it was wrong today),so in history many kings and emperors used silver chopsticks to see if the food was bad for them or not.
In China,chopsticks are traditionally given to a daughter when she marries to hope that they will have a son very soon,because the word"chopsticks"in Chinese is pronounced like"quick son".People often believe chopsticks have something to do with good luck.So on New Year's Eve many families will put new chopsticks on the table at dinner as a way of wishing for luck,and dropping chopsticks is a sign of bad luck to come.
It's believed that using chopsticks can increase fingers'dexterity,that means if we often use chopsticks at dinner,it can make our fingers do everything freely.It can improve memory,too.Many westerners,businessmen,tourists put their knives and forks beside the bowls and plates,but choose chopsticks in China.
根據(jù)短文內(nèi)容,從A、B、C、D四個(gè)選項(xiàng)中選擇正確答案,并將其字母代號(hào)在答題卡相應(yīng)位置上填涂.

B.they liked green stone       
C.they loved tusks of elephants
