9、10、11、12、13题:Because Ireland is an island geographically near the mainland of the United Kingdom, English rulers have fought since the Middle-English Ages to retain political control over it. Attracted by the lush farmland, English and Scottish landowners settled there, and in time of famine or political unrest, the local workers suffered, while their landlords were cushioned by their wealth. The history of modern Ireland is, in fact, largely a story of antagonism and resentment between the Irish and their English and Scottish rulers.
Since the 1920's, Ireland has been divided into two parts: Northern Ireland (Ulster) and the Republic of Ireland (Eire). The north is still part of the United Kingdom and is predominantly Protestant; the south is an independent republic and is mainly Catholic. The majority in Ulster accept this political compromise, but the active and mainly Catholic minority are fighting for union with the independent republic of Southern Ireland. The IRA, the Irish Republican Army, have mounted bombing campaigns in military and civil targets in Ulster and England. They have sent letter-bombs to public figures, they have slot fellow Irishmen who support the British or belong to opposing, and now equally militant Protestant groups. As a result of this, the British have stationed an army in Belfast, the IRA have been outlawed, and several of them have spent many years in prison or have died in support of their cause. Whether this level of violence and repression is justifiable, and whether the violence that could result from political change would be worthwhile are the controversial issues that divide everybody involved.
36. It suggested that the central problem is relationship between _______.
A. Britain and Ireland
B. Ulster and Eire
C. Catholics and Protestants
D. the Irish Republican Army and Ulster.
37. This outline suggests that the central problem is ________.
A. many centuries old
B. about three centuries old
C. about 80 years old
D. a few years old
38. The IRA is ________.
A. part of the Ulster police force
B. part of American army
C. a group of militant priests
D. a terrorist organization
39. Bomb attacks occur _______.
A. only in England
B. when public figures talk about Ireland
C. only in Northern Ireland
D. in England and Northern Ireland
40. The writer feels that the controversy is about ________.
A. freedom
B. political change
C. the use of violence
D. injustice

14、15、16、17、18题:T[ornadoes,whirlwinds,and watersprouts are rotating funnel cloud air masses of small diameter.They are differentiated by the intensity of their rotation and by
the surfaces that they traverse.Though tornadoes and whirlwinds both travel over land masses,whirlwinds are atmospheric systems smaller than tornadoes.Watersprouts are tornadoes that form or pass over a water surface.A tornado is a powerful vortex or “twister” whose rotational speeds are estimated to be near 300 miles per hour.The first visible indication of tornado development is usually a funnel cloud.As this funnel dips earthward,it becomes darker because of the debris
that is forced into its intensifying vortex.Some tornadoes give no visible warning until their destruction strikes the unsuspecting victim.Tornadoes often occur in groups,and several twisters sometimes descend from the same cloud base.The forward speed of a tornado is normally 30 to 40 miles per hour.In the short time that it takes to pass,a tornado can cause fantastic destruction.There have been cases reported in which blades of straw were embeded in fence posts.
