【題目】 改革開放以來(lái),我國(guó)出現(xiàn)新的人口遷移現(xiàn)象。大規(guī)模的人口遷移深刻影響著我國(guó)許多地區(qū)社會(huì)、經(jīng)濟(jì)和環(huán)境的發(fā)展變化。據(jù)此完成下面小題。

1我國(guó)東南沿海城市吸引大量農(nóng)村勞動(dòng)力遷人的主要原因是( )

A.氣候宜人B.環(huán)境優(yōu)美C.經(jīng)濟(jì)發(fā)達(dá)D.婚姻家庭

2大量農(nóng)村人口遷入城市,對(duì)城市發(fā)展的有利影響是( )

A.減輕就業(yè)壓力B.緩解交通壓力C.提升科技水平D.提供豐富勞動(dòng)力

【答案】

1C

2D

【解析】

1影響人口遷移的因素包括自然環(huán)境因素:氣候、淡水、土壤、礦產(chǎn)等;社會(huì)經(jīng)濟(jì)因素:經(jīng)濟(jì)發(fā)展、交通和通信、文化教育、婚姻家庭等;政治因素:政策、社會(huì)變革、戰(zhàn)爭(zhēng)等。我國(guó)東南沿海地區(qū)吸引大量民工遷入的主要原因是改革開放后,東南沿海經(jīng)濟(jì)發(fā)展迅速,工資水平高,吸引大量的農(nóng)村勞動(dòng)力遷入。C正確,故選C。

2大量的農(nóng)村勞動(dòng)力遷入城市,為城市提供了大量的勞動(dòng)力,D正確。加重了就業(yè)的壓力,A錯(cuò)誤。增加交通的壓力,B錯(cuò)誤。農(nóng)村勞動(dòng)力素質(zhì)低,對(duì)科技推動(dòng)不大。C錯(cuò)誤。故選D。

本題難度較小,主要考查了影響人口遷移的因素,理解即可。

【題目】閱讀理解

閱讀下列短文,從每題所給的四個(gè)選項(xiàng) (A 、B 、C D )中,選出最佳選項(xiàng)。

In 1841, a book was published which astonished the world. It was called “Incidents of Travel in Central America, Chiapas and Yucatan”. The author John Loud Stephens had just returned from a long, difficult and dangerous journey through the thick rain forest of southern Mexico and Guatemala. He had once been there with Frederick Catherwood, an architect and artist, to search for the remains of a lost civilization known as the Mayas(瑪雅). Very little was known about the Mayas at that time, but Catherwood's drawing in the book showed incredible cities with temples, pyramids and other buildings as impressive as those of their northern neighbors, the Aztecs. These cities, however, were deserted. The inhabitants(居民) had disappeared almost a thousand years before.

Since that time, far more has been learned about this remarkable civilization. The Mayas had a highly-developed system of government and of agriculture, as well as an incredibly accurate system of measuring time. They were also wonderful engineers capable of moving huge blocks stone long distances and cutting them to accurate shapes and sizes.

And yet although the Mayas knew about the wheel, they never used it. Neither did they use metals other than copper. What is ever more surprising is that they suddenly abandoned many of their cities and built new ones in the jungle. Some time around AD 900, Mayan civilization collapsed(崩潰). By the year 1200, their last great capital, Itza, was deserted.

Who were these strange people and the even stranger gods they worshipped? What brought about their sudden and mysterious collapse? Some writers have tried to prove that the Mayas had contact with visitors from space and even that they themselves came from another planet. Some people believe that their civilization came to an end because the Mayas never developed a proper resistance to local germs and diseases. All we really know is that when the first Europeans appeared off their coast in 1517, this great and mysterious culture was only a memory.

【1】Stephen's book astonished the world because .

A. it was the first time people heard about Mayas

B. the Mayas were excellent builders and farmers

C. he had experienced so may difficulties to find this lost civilization

D. it described that the Mayas used to be an advanced civilization

【2】 One of the most surprising findings about Mayas was that .

A. they developed accurate system measuring time

B. they knew how to build pyramids with stones

C. they deserted their cities and moved to new ones

D. they built cities which they never lived in

【3】At last Mayas disappeared from the world most probably in .

A. a thousand years before 1841

B. around AD 900

C. any year between 1200 and 1517

D. 1200

【4】What brought about Mayan sudden collapse?

A. Tropical germs and diseases.

B. European conquest.

C. Mysterious force from outer space.

D. No one knows for sure.
