下面為大家搜索整理的有關(guān)備考新gre數(shù)學(xué)易錯(cuò)題型解析,雖然數(shù)學(xué)是我們的強(qiáng)項(xiàng),但是也不能疏忽大意,不僅不能輕敵,還要更加細(xì)心,不要被這些易錯(cuò)題蒙蔽雙眼。大家在備考新gre數(shù)學(xué)考試時(shí)可以根據(jù)以下所提到的易錯(cuò)題型為自己查漏補(bǔ)缺。
1,l1, l2 and l3 are three lines in space
The number of points at The number of points at
which lines l1 and l2 intersect which lines l2 and l3 intersect
1.三條任意直線,L1和L2的交點(diǎn)的個(gè)數(shù)與L2和L3的交點(diǎn)的個(gè)數(shù)沒關(guān)。
2. The number of 1/4-inch lengths in 1
a 4-inch length
2,是問4英尺中有多少個(gè)1/4英尺,應(yīng)該是16個(gè),所以是A
3. The maximun number of solid cubes 4
having edges of length 1/2 meter that
can be placed inside a cubical box
having inside edges of length 1 meter
3邊長為1的立方體里最多能放下幾個(gè)邊長為1/2的立方體,當(dāng)然是8個(gè)咯
4. Cube C has volume 8 cubic centimeters
The area of one of the faces of cube C 3 square centimeters
4立方體體積是8,那一個(gè)面的面積當(dāng)然是4咯
5. Ms.Smith got an 8 percent cost-of-living raise of $20 per week
Ms.Smith's new weekly salary $260
5 x*0.08=20,那x+20=270>260
6. On a certain number live, if -7 is a distance of 4 from n and 7 is a distance of 18
from n then n=
A.25 B.11 C.3 D.-3 E-11
6應(yīng)該是-11
7. For all real numbers a and b. if a·b=a(a+b), then a·(a·b)=
A. a2+ab B a2+ab+a C a2+a+b D a3+a2b E a3+a2b+a2
注:a2表示a平方,a3表示a立方
7新定義的運(yùn)算a·b=a(a+b), 那a·(a·b)=a·(aa+ab)=a(a+aa+ab)=aa+aaa+aab
8.secretary typed 6 letters,each of which had either 1 or 2 pages.If the secretary typed 10 pages in all, how many of the letters had 2 pages?
A 1 B 2 C 3 D 4 E 5
答案是D,題目我都看不懂,是啥意思呢?
這是說秘書打六封信,沒一封信要1頁或者兩頁。如果秘書總共打了10頁,那么有多少封信是兩頁?
解答:設(shè)有x封,則2x+(6-x)=10,解得x=4.
9 how many of the five numbers above are each equal to the product of an integer and an odd integer that greater than 1?
這五個(gè)數(shù)是:2 6 8 14 16
a.none b.one c.two d.there e.four
我覺得這道題除了2不可能,其它四個(gè)數(shù)都有可能.可答案是c,想問大家為什么?
題目意思是這5個(gè)數(shù)哪些可以是2個(gè)>1的數(shù)的積,一個(gè)是奇數(shù),一個(gè)是整數(shù),只有6和14的因數(shù)中有奇數(shù),所以C.
10 這句話大家看該怎樣列式子呢?這是一道圖表題.
what was the approximate percent increase in personal income from 1965 to 1970?
是這樣(1970-1965)/1965還是(1970-1965)/1970這樣?
是這樣:(1970-1965)/1965
以上即是備考新gre數(shù)學(xué)易錯(cuò)題型介紹,希望對大家的新gre數(shù)學(xué)考試有所幫助。新GRE數(shù)學(xué)考試中也有難點(diǎn),這就需要我們努力攻克,爭取把我們的優(yōu)勢發(fā)揮到最好。
