It comes as some surprise to discover that, in previous centuries, this pretty simple backwater was one of the main     1     (stop) in a Caucasian branch of the classic Silk Route. And the work being done here today is part of a far     2     (wide) recovery of East-West trade across the area.

The Great Silk Route, or Silk Road, was the fabled overland supply chain famously     3     allowed the supply of Chinese goods     4     (reach) ancient Rome from the second century BCE.

In an ancient world without trains or planes,     5     (transport) valuable goods across vast inhospitable lands of Eurasia required well equipped teams of pack animals—    6     (typical) camels travelling in groups known as caravans (商队).

These would usually seek overnight     7     (safe) in solid walled fences where the traders could find accommodation and food. This developed     8     caravanserais (商队旅馆) all along the trade routes: precursors (前身) of traveller’s inns, but for a pre-motorized age.

Despite     9     name, the Silk Route was always a separate network rather than a single “route” and that trade was in much more than just silk. Pepper and spices     10     (be) also in demand in pre-medieval Europe, while so much silver and gold flowed east to pay for these luxuries (奢侈品) that Rome faced a balance-of-payments reduction in the third century CE.

Nearly 95%of man-made diamonds and diamond powder of the world are made in Henan Province, according to a news report. Henan Province has become the leading player in man-made diamonds of the world. In 1953, the first lab grown-diamond     1     (make) in Sweden by applying high temperature and high pressure(HTHP). And China had to research     2     develop its own techniques on making diamond-grade drilling bits (钻头).

In 1964,     3     institute in Henan produced China’s first six-faced HTHP facility to produce diamond for industrial use,     4     (mark) the improvement of diamond-making technology. In1966, the six-faced HTHP pressing machines were produced greatly. The products were     5     (wide) used in glass, mining and other fields. Another milestone was after 2000. Thanks     6     technological advantages and orders from the rest of the world, a large number of man-made diamond     7     (company)appeared in Zhengzhou, Xuchuang, Shangqiu and Nanyang.

An industry expert said the     8     (different) between natural diamonds and man-made diamonds is like that between ice in the river and ice in the icebox.

4 . With the weight of its tall buildings, streets and people, New York City is sinking at an average rate of 1 to 2 millimetres each year, a new study says.

The sinking is called “subsidence”. That natural process happens everywhere as ground is compressed (压紧). But the study sought to estimate how the huge weight of the city itself is hurrying things along.

Over 1 million buildings are spread across five boroughs (自治区). The research team found that all those structures add up to 1. 5 trillion metric tons of concrete, metal and glass, equal to the mass of 4, 700 Empire State buildings pressing down on the Earth.

The rate of compression is different throughout the city. Midtown Manhattan’s skyscrapers are largely built on rock, which compresses very little. But some parts of Brooklyn, Queens and downtown Manhattan are on looser soil and sinking faster, the study said.

While the process is slow, parts of the city will eventually be under water. Researchers reached conclusions using satellite imaging, data modeling and mathematical calculations. It will take hundreds of years before New York becomes Venice, which is famously sinking into the Adriatic Sea. But parts of New York are more at risk. A researcher said Manhattan is at risk because of the borough’s large weight.

The ocean is rising at a similar rate that the land is sinking. So the Earth’s changing climate could speed up the process for parts of the city to go under water. Already, New York City is at risk of flooding because of large storms. Storms like Sandy in 2012 caused the ocean to expand inland and flooded neighbourhoods after a lot of rain.

New York City is not the only place sinking. San Francisco, California, is also at risk because of pressure on the ground and the area’s active earthquakes. In Indonesia, the government is preparing for a move from Jakarta, which is sinking into the Java Sea. The government is building a new capital being constructed on the higher ground of an entirely different island.

1. What is the main reason for the different compression rates in New York?

A．Different measurement methods.	B．Different geological(地质的)conditions.
C．Different building materials and styles.	D．Different climate changes and impacts.

2. What is the basic reason for Manhattan to be Venice?

A．Its huge weight.	B．Its distance to the sea.
C．Its similar position.	D．Various frequent natural disasters.

3. What is the purpose of the last paragraph?

A．To keep the reader’s attention.

B．To improve the atmosphere.

C．To show the issue is common.

D．To point out the negative effect of sinking.

4. What is a suitable title for the text?

A．New York City Is Slowly Sinking	B．The Flavour of New York City
C．Here Comes a Future Venice	D．The Problems Caused by Dropping

       Gulao, a water town in China’s Jiangmen City, was built on tidal flats (潮坪地貌) where farmers and fishermen pushed the dirt around     1     (form) ponds.

     “During the fishing civilization period, roads     4     (construct) poorly, so water systems became key routes of transportation,” states LUO Studio. “Bridges needed to be walkable, while also     5     (ensure) more space for boats to pass through, so traditional bridge construction techniques in China adopted arches (拱形) to create space.”
       Arched bridges, sometimes     6     (call) moon bridges, are high enough in the middle for boats to get under. But these     7     (model) often have rising stairs up each side not to extend very far into the surrounding fields.
       LUO Studio has designed this covered arch bridge out of wood,     8     is evidently common in the area. The initial intention is to strengthen the bridge structure,     9     keep the wood dry. This project also inherits (继承) the construction wisdom of ancient covered bridges. The covered passage enhances the overall structural     10     (stable) and protects the arched wooden structure from exposure to sun and rain.
