Question

One of the most popular activities enjoyed by Americans is spending time in forests and walking along paths through the country.This activity，called hiking，has led to the creation of paths throughout the United States.

One of the longest is the Appalachian National Scenic Trail.The trail is the first completed part of the National Trails System.The trails system was established by Congress and the president in 1968.The Appalachian Trail is more? than 3,400 kilometers long.It starts in the northeastern state of Maine and ends in the southeastern state of Georgia.The trail goes through 14 states.They are Maine，New Hampshire，Vermont，Massachusetts，Connecticut，New York，New Jersey，Pennsylvania，Maryland，West Virginia，Virginia，Tennessee，North Carolina，and Georgia.

The path takes walkers through the Appalachian Mountains.They extend from the Canadian province of Quebec to the southern American state of Alabama.

The Appalachian Mountains are among the oldest on Earth.They first began forming about one thousand million years ago.During the millions of years since then，the mountains were changed and reformed by the forces of water and wind.Ice also changed the mountains，making many of them smaller and digging valleys and lakes among them.Many different kinds of trees grow along the trail.And many different kinds of animals live in the forests along the trail.

Lands along the trail are protected by the federal government and by state governments.Some parts are not protected by the government directly.Instead，they are protected by legal agreements with private owners willing to permit people to walk across their property.

Walkers on the Appalachian Trail pass through some of the great valley systems of the mountains.They can look down into these beautiful valleys and see farms and forests stretching across the land for many kilometers.Farmland in the valleys is rich and productive.And some of the great events in American history took place in the valleys.For example，one of the great battles of the American Civil War was fought in the Shenandoah Valley in Virginia.

4.A

【解析】

1.

解析　細(xì)節(jié)理解題。根據(jù)文章第二段可知，A項(xiàng)數(shù)字錯(cuò)誤；B項(xiàng)地理位置描述欠精確；C項(xiàng)應(yīng)該把more than去掉。

2.2】　C

解析　細(xì)節(jié)理解題。根據(jù)第四段第三、四句可知，水、風(fēng)以及冰川都對(duì)山貌的變化起到了一定作用，而這些都是自然力。

3.3】　D

解析　細(xì)節(jié)理解題。由第五段第一句可知，這些土地同時(shí)受聯(lián)邦政府和州政府的保護(hù)。

4.4】　A

解析　主旨大意題。最后一段提到農(nóng)場(chǎng)和森林綿延數(shù)公里，并沒(méi)有提到grassland，因此B項(xiàng)錯(cuò)誤；文中提到的歷史事件是發(fā)生在美國(guó)內(nèi)戰(zhàn)時(shí)期，而非獨(dú)立戰(zhàn)爭(zhēng)時(shí)期，所以C項(xiàng)錯(cuò)誤；D項(xiàng)文中沒(méi)有提到；只有A項(xiàng)內(nèi)容與本段的主旨句第一句相符。
