Section A
Directions: In this ction, there is a passage with ten blanks. You are required to lect one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Plea mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not u any of the words in the bank more than once.
Steel is valued for its reliability, but not when it gets cold. Most forms of steel __26__ become brittle （脆的）at temperatures below about -25℃ unless they are mixed with other metals. Now, though, a novel type of steel has been developed that resists __27__ at much lower temperatures, while retaining its strength and toughness—without the need for expensive __28__.
Steel's fragility at low temperatures first became a major concern during the Second World War. After German U-boats torpedoed （用鱼雷攻击）numerous British ships, a 2,
700-strong fleet of cheap- and-cheerful "Liberty ships" was introduced to replace the lost vesls, providing a lifeline for the __29__ British. But the steel shells of hundreds of the ships __30__ in the icy north Atlantic, and 12 broke in half and sank.
Brittleness remains a problem when building steel structures in cold conditions, such as oil rigs in the Arctic. So scientists have __31__ to find a solution by mixing it with expensive metals such as nickel.
Yuuji Kimura and colleagues in Japan tried a more physical __32__. Rather than adding other metals, they developed a complex mechanical process involving repeated heating and very vere mechanical deformation, known as tempforming.
The resulting steel appears to achieve a combination of strength and toughness that is __33__ to that of modem steels that are very rich in alloy content and, therefore, very expensive.
Kimura's team intends to u its tempformed steel to make ultra-high strength parts, suc
h as bolts. They hope to reduce both the number of __34__ needed in a construction job and their weight—by replacing solid supports with __35__ tubes, for example. This could reduce the amount of steel needed to make everything from automobiles to buildings and bridges.

The future of personal satellite technology is here—are we ready for it?
A）Satellites ud to be the exclusive playthings of rich governments and wealthy corporations. But increasingly, as space becomes more democratized, they are coming within reach of ordinary people. Just like drones （无人机）before them, miniature satellites are beginning to fundamentally transform our conceptions of who gets to do what up above our heads.
B）As a recent report from the National Academy of Sciences highlights, the satellites hold tremendous potential for making satellite-bad science more accessible than ever before. However, as the cost of getting your own satellite in orbit drops sharply, the risks of irresponsible u grow. The question here is no longer "Can we?" but "Should we?" What are the potential downsides of having a slice of space denly populated by equipment built by people not traditionally labeled as "professionals" ? And what would th
e responsible and beneficial development and u of this technology actually look like? Some of the answers may come from a nonprofit organization that has been building and launching amateur satellites for nearly 50 years.
C）Having your personal satellite launched into orbit might sound like an idea straight out of science fiction. But over the past few decades a unique class of satellites has been created that fits the bill: CubeSats. The "Cube" here simply refers to the satellite's shape. The most common CubeSat is a 10cm cube, so small that a single CubeSat could easily be mistaken for a paperweight on your desk. The mini-satellites can fit in a launch vehicle's formerly "wasted space. " Multiples can be deployed in combination for more complex missions than could be achieved by one CubeSat alone.
