There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids. The most famous of these are the "Step" pyramid and the "Bent" pyramid.
Some of the pyramids still look much the same as they must have done when they were builtthousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often,__________(47). The dry climate of Egypt has helped to preserve the pyramids, and their very shape __________ (48). These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last for ever.
It is practically certain that plans were made for the building of the pyramids __________(49).
However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves. Consequently, we are only able to guess at the methods used.

B. has made them less likely to fall into ruin
C. before they could begin to build
D. because the plans of other large works have fortunately been preserved

答案與解析：
46.F。根據上下文語義——上文講到金字塔已經矗立了5千年之久，因此，此處填入金字塔似乎還能堅持數千年最合適。
47.A。此處用語法原則來判斷最合適，前一句有look for，兩空格前有and，需要填入一個帶介詞的並列結構，直接判定選擇A，主要講述的是那些去金字塔尋找現代建築能使用的石頭材料的.人破壞了金字塔。
48.B。此句在分析金字塔千年屹立不倒的原因——形狀。
49.D。上文有plan，根據重複原則，我們首先確定D可選，再通過上下文的語義能最終確定D為正確答案。
50.C。此句表達的是在開始脩金字塔之前，必須進行數月仔細的計劃。
