Ⅰ.阅读理解
A tsunami is a natural disaster. The word “tsunami” comes from Japanese.
A tsunami is a very large sea wave that forms mainly in the Pacific Ocean area. People may be killed and property can be destroyed when a tsunami hits land.
What causes these dangerous sea waves? Sometimes, tsunamis are caused by earthquakes taking place underwater. After earthquakes, water begins to move up and down. Waves begin to form, and each wave of this kind is called a tsunami.
A tsunami is less than one meter high and can move at a speed of almost 800 kilometers per hour while it is far out in the ocean. But it rises higher and higher and moves more and more slowly as it comes closer to land.
The meteorological bureau (气象局) warns people over the radio and television when a tsunami is heading for land. These warnings have helped save many lives.

参考范文：
Dear Sir/Madam，
On June 17th, 2019, a great earthquake measuring 6.0 on the Richter scale hit my hometown, Yibin City, Sichuan province, leaving many houses in ruins. Yesterday our class had a discussion on how to rebuild the quake-stricken areas.
We all hold the view that the quake-stricken areas will benefit a lot from the help offered from all over the country, as some areas are badly in need of money and materials. In addition, the help from outside will greatly relieve those who, though alive, are suffering great sorrow and pain. Meanwhile, it’s vital that all the victims should act to help themselves. Through active participation in reconstruction, we will pull ourselves through.
Yours，
Li Hua Ⅲ.概要写作
阅读下面短文，根据其内容写一篇60词左右的内容概要。
Most of the survivors have to stay in the open area overnight after a 7.1-magnitude quake toppled (使倒塌) houses, cut off power and first-aid materials supply in northwest China’s Qinghai Province Wednesday while rescuers face difficulties in sear ching for the buried.
Rescuers have set up more than 40 tents for survivors in the Gyegu Town, near the epicenter (震中) in the Tibetan Autonomous Prefecture of Yushu in southern Qinghai. But the effort seems far less than enough for the area inhabited by some 100,000 people.
Many people sought temporary shelters in buildings that remained unaffected by the tremor (轻微地震)．
In the yard of Yushu’s Sports Committee, nearly 1,000 people were sitting or lying on the ground in sheer (完全的，十足的) darkness. Some wrapped themselves up with quilts taken out from the debris (碎片，残骸)．
Some brought their own tents and others turned on the lights of motorcycles.
“I’m hungry and thirsty. We’ve been waiting for help since the morning，” said Zhaxi Toinzhub.
The woman said her three children were still buried in the rubble (碎石，瓦砾)．
The National Meteorological Station forecast Wednesday that temperatures may hit minus 3 degrees Celcius at night and 15 degrees Celcius in the daytime in the coming days.
The town would see strong winds and sunny weather in the coming days, providing favorable conditions for rescue operations.
The town is located in a remote area in Qinghai and the quake and ensuing (随后的) landslides have damaged roads, causing great difficulties for rescuers and, especially, machines from outside to enter the region.
“Rescuers had to dig with bare hands or iron sticks Wednesday, looking forward to the arrival of digging machines，”said a rescuer surnamed Wang, who was working at a collapsed hostel.
“The searching operation became even harder at night without lighting facilities，” he said.
In addition, rescuers may easily get exhausted working at a place with an altitude (海拔) of above 4,000 meters.
Thousands of rescuers and medical staff are rushing to Yushu from many regions of China, bringing machines, disaster-relief materials and medicines to the quake-hit town. Governments, organizations, enterprises and individuals are offering donations of money and materials to the region.

课时跟踪检测（三十八） 空间几何体及表面积与体积 [A 级 保分题——准做快做达标] 1.关于空间几何体的结构特征，下列说法中不正确的是( ) A ．棱柱的侧棱长都相等 B ．棱锥的侧棱长都相等 C ．三棱台的上、下底面是相似三角形 D ．有的棱台的侧棱长都相等 解析：选B 根据棱锥的结构特征知，棱锥的侧棱长不一定都相等． 2．一个球的表面积为16π，那么这个球的体积为( ) A. 16 3 π B.323 π C ．16π D ．24π 解析：选B 设球的半径为R ，则由4πR 2 ＝16π，解得R ＝2，所以这个球的体积为43πR 3＝323 π. 3．如图所示，等腰△A ′B ′C ′是△ABC 的直观图，那么△ABC 是( ) A ．等腰三角形 B ．直角三角形 C ．等腰直角三角形 D ．钝角三角形 解析：选B 由题图知A ′C ′∥y ′轴，A ′B ′∥x ′轴，由斜二测画法知，在△ABC 中， AC ∥y 轴，AB ∥x 轴，∴AC ⊥AB .又因为A ′C ′＝A ′B ′，∴AC ＝2AB ≠AB ，∴△ABC 是直角 三角形． 4．下列说法中正确的是( ) A ．各个面都是三角形的几何体是三棱锥 B ．以三角形的一条边所在直线为旋转轴，其余两边旋转形成的曲面所围成的几何体叫圆锥 C ．棱锥的侧棱长与底面多边形的边长相等，则该棱锥可能是六棱锥 D ．圆锥的顶点与底面圆周上的任一点的连线都是母线 解析：选D 当一个几何体由具有相同的底面且顶点在底面两侧的两个三棱锥构成时，尽管各面都是三角形，但它不是三棱锥，故A 错误；若三角形不是直角三角形或是直角三角形但旋转轴不是直角边所在直线，所得几何体就不是圆锥，故B 错误；若六棱锥的所有棱都
课时跟踪检测(三十三) 数 列 求 和 1．已知{a n }是首项为1的等比数列，S n 是{a n }的前n 项和，且9S 3＝S 6，则数列???? ?? 1a n 的 前5项和为( ) A.158或5 B.3116或5 C.3116 D.158 2．已知数列{a n }的前n 项和S n ＝an 2＋bn (a 、b ∈R )，且S 25＝100，则a 12＋a 14等于( ) A ．16 B ．8 C ．4 D ．不确定 3．数列112，314，518，7116，…，(2n －1)＋1 2n ，…的前n 项和S n 的值等于( ) A ．n 2＋1－1 2n B ．2n 2－n ＋1－1 2 n C ．n 2＋1－ 12 n －1 D ．n 2－n ＋1－1 2 n 4．(2019·“江南十校”联考)若数列{a n }为等比数列，且a 1＝1，q ＝2，则T n ＝1a 1a 2＋ 1 a 2a 3 ＋…＋ 1 a n a n ＋1 的结果可化为( ) A ．1－1 4n B ．1－1 2n C.2 3??? ?1－14n D.2 3? ???1－12n 5．(2019·珠海模拟)已知等差数列{a n }的前n 项和为S n ，a 5＝5，S 5＝15，则数列???? ? ?1a n a n ＋1的前100项和为( ) A.100101 B.99101 C.99100 D.101100 6．已知函数f (n )＝????? n 2(当n 为奇数时)， －n 2(当n 为偶数时)， 且a n ＝f (n )＋f (n ＋1)，则a 1＋a 2＋a 3＋…＋a 100 等于( ) A ．0 B ．100 C ．－100 D ．10 200 7．在等差数列{a n }中，S n 表示前n 项和，a 2＋a 8＝18－a 5，则S 9＝________. 8．对于数列{a n }，定义数列{a n ＋1－a n }为数列{a n }的“差数列”，若a 1＝2，{a n }的“差数列”的通项公式为2n ，则数列{a n }的前n 项和S n ＝________.
