①In the northeastern India, within sight of the India-Bangladesh border, bridges aren t built一they’re grown. There it is rainy and warm, and the area is marked with many rivers and mountain streams. There a species of Indian rubber tree with a very strong root system grows well.
②The rubber tree called Ficus elastica produces a series of secondary roots from higher up its trunk and they can comfortably rest on the top of huge stones along the riverbanks, or even in the middle of the rivers themselves. The War-Khasis and War-Jaintias, two closely related tribes(部落)in Meghalaya, long ago noticed this tree and saw in its powerful roots an opportunity to easily cross the areals rivers. Now, whenever and wherever the bridges are in need, they^ll simply grow their bridges.
③To make a rubber tree^s roots grow in the right direction一say,over a river一the people of southern Meghalaya have used several different ways In some places like around the 34
④village of Nongriat, betel nut (槟根P) tree trunks 9 cut in half down the middle and made empty inside, are used to create root-guidance systems. The thin, tender roots of the rubber tree grow straight along the trunks and when they reach the other side of the river, they^re allowed to take root in the soil. Given enough time, a living bridge comes into being.
⑤The root bridges can grow as long as the tree remains healthy. Though they can take many years to begin working, the length of time is dependent on local conditions such as the health of the tree the way the bridge is being grown, and the soil conditions. However,once root bridges grow up, they actually gain strength over time一strong enough that some can even support the weight of 50 or more people at a time.
1.Why are there many root bridges in the northeastern India
A.Local people are very clever.
B.Local governments support it.
C.There are some rivers and hills.
D.There is a special kind of rubber tree.
2.In Nongriat, people use betel nut tree trunks to .
A.make the root bridges stronger
B.guide the rubber tree roots’ growth
C.stop rubber tree roots growing in the soil
D.help support the weight on the root bridges
3. Which of the following may decide the growth of a root bridge
A.The speed of the river water.
B.The length of the root bridge.
C.The health of the rubber tree.
D.The number of people walking on the bridge.
4. What does the text mainly talk about
A.Root bridges in India.
B.How to build root bridges.
C.The roots of a species of Indian rubber tree.

【难句解析】
(第二段第一句)The rubber tree called Ficus elastica produces a series of secondary roots from higher up its trunk and they can comfortably rest on the top of huge stonesalong the riverbanks,or even in the middle of the rivers themselves.这种被称为Ficuselastica的橡胶树的较高的树干上会长出很多次生根,这些次生根在沿着河岸的巨石上就能轻易地生长,它们甚至可以扎根于河流的中央。
本句为并列复合句,由并列连词and连接前后两个分句。and前的分句中,called Ficuselastica是过去分词短语,作后置定语,修饰rubber tree;and后的分句中,主语they指的是a series of secondary roots,连词or连接两个作状语的介词短语on the top of huge stones along the riverbanks和even in themiddle of the rivers themselves。

①Starman,the dummy (仿 真人)riding a cherry-red Tesla Roadster through space, has made his closest approach ever to Mars. The electric roadster and its passenger were attached to the top of a Falcon Heavy rocket during the SpaceX rocket^s first test launch on Feb. 6, 2018.
②Two years later, the Falcon Heavy rocket and the vehicle at its tip were making their second trip around the Sun. Mr McDowella Harvard astrophysicist, found that Starman passed 7.4 million kilometers from Mars at 06:25 GMT on October 7, 2020.
③The recent closest approach between the Earth and Mars was nearly 56 million kilometers in 2003,though the planets are often hundreds of millions of miles apart depending on where they are in their orbits. No one can see the Falcon Heavy rocket at its current distance, but orbits over periods of a few years are fairly straightforward to predict and Mr McDowell used data about how the rocket was moving when it left the Earth’s gravity behind to locate its recent movements exactly.
④“ Last time Starman circled the Sun,” McDowell said “it crossed Mars,orbit while the red planet was quite far away. But this time the crossing was lined up with Mars with a fairly close approach, though still not close enough to feel a strong tug from Mars. ”
⑤At this point in time, if you were able to go look at the roadster,it would probably look pretty different. The strong solar radiation environment between the planets would probably have destroyed all the exposed organic materials.
⑥Without the Earths atmospheric and magnetic(磁,性的)protection, even the plastics and carbon-fiber materials would start to break up. Over the course of decades or centuries9 the roadster will end up with its aluminum(铝) frame and hard glass parts一that’s assuming that none of them get destroyed in impacts with passing space rocks.
1.What can we infer from the first two paragraphs
A.Starman now is circling around the Earth in its orbit.
B.Starman has set out on its second trip around the Sun.
C.Starman has traveled 7.4 million kilometers after launch
D.Starman still has a long way to go before getting to Mars.
2.How did Mr McDowell manage to locate the Falcon Heavy rocket
A.By keeping it under visual observation
B.By predicting its future orbit around the Earth
C.By seeking professional help from SpaceX.
D.By analyzing data about the rocket,s movement.
3.What does the underlined word tug in paragraph 4 probably mean
A.Pull. B. Drive.
C. Crash. D. Pressure.
4.What will happen to the roadster in decades or centuries
A.It is circling around Mars and will finally crash onto it.
B.It will finish its mission and return to the Earth.
C.It is likely reduced to at most its frame and glass.
D.It will be repaired by SpaceX during its next space mission.

①Imagine, one day, getting out of bed in Beijing and being at your office in Shanghai in only a couple of hours, and then, after a full day of work, going back home to Beijing and having dinner there.Sounds unusual, doesn't it?But it's not that unrealistic, with the development of China's high-speed railway system. China has an even greater high-speed railway plan to connect the country with Southeast Asia, and finally Eastern Europe.
②China is planning to extend(延长) its own high-speed railway network to up to 17countries in 10to 15years, eventually reaching London and Singapore.
③If China's plan for the high-speed railway goes forward, people could rush from London to Beijing within two days. The new system would still followChina's high-speed railway standard. And the trains would be able to go 346 kilometers an hour, almost as fast as some airplanes.
④China's bullet train(高速列车), the one connecting Wuhan to Guangzhou, already has the World's fastest average speed. It covers 1,069 kilometers in about three hours.
⑤Of course, there are some technical challenges to overcome. There are so many issues that need to be settled, such as safety and maintenance(保养) of railway tracks. So, it's important to pay attention to every detail. But the key issue is really money. China is already spending hundreds of billions of yuan on longer railway construction.
⑥China prefers that the other countries provide natural resources rather than financial investment. Resources from those countries could flood into China to support development.
⑦It'll be a win-win project. For other countries, the railway network will certainly create more opportunities for business, tourism and so on, not to mention the better communication among those countries.
⑧For China, such a project would not only connect it with the rest of Asia and bring some much-needed resources, but would also help develop China's far west. We predict that in the coming decades, millions of people will move to the western parts, where the land is empty and resources unused. With high-speed trains, people will set up factories and business centers in the west. And they'll trade with Central Asian and Eastern European countries.
1.China’s new high-speed railway plan will be a win-win project because ____________.
A.China will get much-needed resources and develop its western regions
B.China and the countries involved will benefit from the project in various ways
C.China will develop its railway system and communication with other countries
D.the foreign countries involved will develop their railway transportation,business and tourism
2.According to the passage,the greatest challenge to the new high-speed railway plan is____________.
A.technical issues
B.safety of the system
C.financial problems
D.maintenance of railway tracks
3.Which of the following words best describes the author’s attitude towards China’s high-speed railway plan
A.Critical
B.Reserved
C.Doubtful
D. Positive
4.Which of the following might be the best title for the passage
A.New Railway Standards
B.Big Railway Dreams
C.High—speed Bullet Trains
D.International Railway Network
