Radar(雷达) is an electrnic device that detects planes, ships, castlines, landmarks, and even strm cluds. The name radar cmes frm the first letters f the wrds radi directin and ranging. As the human eye uses light waves t see, radar “sees” with radi waves. Withut radar, planes culd nt land safely in bad weather and ships culd nt mve safely in thick fg. 36.
In the 1800s it was discvered that radi waves culd be reflected frm bjects. But scientists did nt make great advances in radar research until the 1930s, when the wrld was threatened by war. 37. It has been used widely in almst every cnflict since then.

On the screen an bserver sees a flash, r a blip, that shws the directin and distance f the bject. 38.
Airprt cntrl twers use radar t guide planes in fr safe landings. Almst all large ships depend n radar t prevent cllisins with icebergs r ther ships. 39. Weather frecasters “see” the size, directin, and speed f strms n radar screens. Astrnmers can even use radar t measure accurately the distance t the mn. Thus, the device has generated majr advancements.
40. Huge radar antennas have been installed all ver the United States. They guard us against pssible enemy attacks. We have ballistic-missiles(战略导弹) warning systems that can alert us t attacks when missiles are mre than 1,000 miles away. Other radar systems warn us against enemy aircraft and even spying space satellites.
A. Plice track speeders in radar-equipped cars.
B. These measurements are nw highly accurate.
C. The device can be used in a wide range f fields.
D. During Wrld War II many cuntries used radar effectively.

Time Is Mre Valuable than Mney
Peple ften say, “Time is mney,” but in fact time is mre valuable than mney. When mney is spent, we can earn it back, but when time is lst, it will never return. The time we have in all ur life is limited, and it is even mre precius fr us senir students. Time is easily lst because f the fact that it is nt scarce thugh it is limited, s it shuld be valued mst.
In a wrd, we shuld get int the gd habits f saving time and never leave what can be dne tday until tmrrw.
论点
时间比金钱更为宝贵
论据
1.失去的金钱可以再挣回来，失去的时同却永不复返；
2.人的一生是有限的，高中生学习的时间更是珍贵的；
3.时间珍贵却不稀有，正因为如此，时间很容易被浪费，所以时间显得特别珍贵。
结论
我们应该养成珍惜时间的习惯，决不要把今天的事留到明天。

China has cmpleted its hme-grwn BeiDu Navigatin(导航) Satellite System (BDS) with the successful launch f tw mre BDS-3 satellites, 19 in all, and has started prviding services t cuntries participating in the Belt and Rad Initiative (BRI) since the end f 2018. The BDS, which will cmpete against the US’ Glbal Psitining System (GPS), will prvide high-precisin, reliable psitining, navigatin and timing services anywhere in the wrld by the end f 2020.
The Belt and Rad Initiative is an ambitius effrt t imprve reginal cperatin and cnnectivity in a trans-cntinental range.

“This is a key step fr the BDS develping frm a Chinese hme system t a reginal and then a glbal navigatin system,” said Yang Changfeng, chief designer f the BeiDu system.

China develped the BDS thrugh a unique technlgical apprach, cntributing Chinese wisdm t the thery and cnstructin f internatinal satellite navigatin systems.
Altgether 18 BDS satellites have been sent int space in 2018, making this year the mst intensive launch f the BDS satellites. They imprved their wrk efficiency by refrming the management prcess. The number f satellite staff at the launch center has been reduced by nearly half, and the testing time befre launch has been shrtened by nearly a third. In the CAST prductin base in Beijing, several BDS satellites are being manufactured at the same time. They try t imprve intelligent manufacturing capability, and cut dwn prductin times. Cnstructin f the BDS-3 system has accelerated.
Once the BDS is fully cmpleted, it will be the furth glbal satellite navigatin system after the US GPS system, Russia’s GLONASS and the Eurpean Unin’s Galile. India t, is building its navigatinal system called the Indian Reginal Navigatin Satellite System (IRNSS), with an peratinal name f NAVIC.

Radar(雷达) is an electrnic device that detects planes, ships, castlines, landmarks, and even strm cluds. The name radar cmes frm the first letters f the wrds radi directin and ranging. As the human eye uses light waves t see, radar “sees” with radi waves. Withut radar, planes culd nt land safely in bad weather and ships culd nt mve safely in thick fg. 36.
In the 1800s it was discvered that radi waves culd be reflected frm bjects. But scientists did nt make great advances in radar research until the 1930s, when the wrld was threatened by war. 37. It has been used widely in almst every cnflict since then.
Eches make it pssible fr radar t wrk. When a beam f radi waves is sent ut, it strikes n an bject and returns an ech. This ech is picked up by radar and recrded n a screen similar t televisin screen. On the screen an bserver sees a flash, r a blip, that shws the directin and distance f the bject. 38.
Airprt cntrl twers use radar t guide planes in fr safe landings. Almst all large ships depend n radar t prevent cllisins with icebergs r ther ships. 39. Weather frecasters “see” the size, directin, and speed f strms n radar screens. Astrnmers can even use radar t measure accurately the distance t the mn. Thus, the device has generated majr advancements.
40. Huge radar antennas have been installed all ver the United States. They guard us against pssible enemy attacks. We have ballistic-missiles(战略导弹) warning systems that can alert us t attacks when missiles are mre than 1,000 miles away. Other radar systems warn us against enemy aircraft and even spying space satellites.
A. Plice track speeders in radar-equipped cars.
B. These measurements are nw highly accurate.
C. The device can be used in a wide range f fields.
D. During Wrld War II many cuntries used radar effectively.
E. It is therefre especially valuable t shippers and travelers.
F. Tday radar is used by cmmercial airliners and weather frecasters.

Time Is Mre Valuable than Mney
Peple ften say, “Time is mney,” but in fact time is mre valuable than mney. When mney is spent, we can earn it back, but when time is lst, it will never return. The time we have in all ur life is limited, and it is even mre precius fr us senir students. Time is easily lst because f the fact that it is nt scarce thugh it is limited, s it shuld be valued mst.
In a wrd, we shuld get int the gd habits f saving time and never leave what can be dne tday until tmrrw.
