1．If you are in a crowd，a first and most important thing is to make yourself familiar with your surroundings（周围的事物） and mentally notice alternate exits．No matter where you are，make sure you always know how to get out．
Make sure you know the type of ground you are standing on．For example，in a crowd of moving people wet ground can be dangerous，causing you to fall．You should know the general atmosphere of the event，as panic situations can often be predicted．When in danger，a few seconds can make all the difference，giving you the possibility of taking advantage of your escape route．Always stay closer to the escape route．
If you find yourself in the middle of a moving crowd，do not fight against the pressure，do not stand still or sit down，because you could easily get injured or even be killed by being stepped on by other people．Instead，move in the same direction of the crowd； take advantage of any space that may open up to move sideways to the crowd movement where the flow is weaker．Keep your hands up by your chest，which will protect your chest during the movement．
If you fall，get up quickly．If you can't get up because you are injured，get someone to pull you back up．If you fall and can not get up，keep moving by crawling（爬行） in the same direction of the crowd．Do not lie on your stomach or back，as this is dangerous for your body．
The worst situation is to be pushed by the crowd against an immovable object．Try to shun High walls，as the crowd pressure can build up rapidly．After you're pushed forward，the way you move is on a diagonal（斜线）．There's always space between people．You work your way out that way till you get out of the crowd．

18．An American company has built a new drone（无人机）that could improve the speed of deliveries（送交的货）．
The drone is very different from other unmanned aircraft．It is made almost completely out of cardboard and has no motor．It can be packed with materials and sealed up with tape．
Because the drones do not have a motor，they are designed to be dropped from airplanes．Hundreds of drones could be sent out at once．Then they could be automatically guided to where they are supposed to go．The company says these drones could then complete deliveries to different places over an area covering hundreds of kilometers．The drones look bigger than the paper airplanes we used to make as kids．But this light flyer is not a toy．It is aerodynamically designed and equipped with a small computer，a battery and sensors to guide it to the ground．
The drones are being developed by Otherlab-a technology research company in San Francisco，California．It calls the drone a"Sky Machine．"
The company says it can travel about 150 kilometers at speeds up to 88 kilometers an hour．Now，it can carry materials weighing up to one kilogram，but future models are expected to carry larger loads．
One of the drone's main advantages is that it does not have a heavy motor or large battery．This allows more room for materials and makes the drone cost less to build and operate．
The Otherlab development team has called its invention the"Ikea of drones．"This is because it is packaged similarly to products from the Swedish furniture maker Ikea．The drone arrives as flat pieces of pre-cut cardboard that can be quickly and easily put together．
The technology that guides the drone can make it land within 10 meters of its target，according to Otherlab．Unlike other drones，even a crash landing is acceptable．The company says the drones can also be reused．
Once the drone completes its delivery，it can be thrown away and the cardboard material will likely break down within a few months．
The company has received money from the U．S．Department of Defense to carry out research on the drones．The money came from the Defense Advanced Research Projects Agency．The agency is attempting to find the best delivery vehicles that can disappear after their missions are complete．The U．S．military has a need for delivery drones．But it wants to simplify and lower the cost of using them．Otherlab's Sky Machines are an attempt to fill that need．
Military drones can also be stolen and studied by others if found after use．Before they can truly disappear，the electronic materials inside must also somehow disappear．Researchers are still working on ways to get the technology itself to self-destruct．

63．What does Paragraph 3 mainly talk about？C
A．Why the new drone is invented．
B．What the new drone is equipped with．
C．How can the new drone get to the ground．
D．Why the new drone is designed like paper airplanes．
64．Why is the invention called the"Ikea of drone"？B
A．Because it's a product made by Ikea．
B．Because it uses the idea from Ikea．
C．Because it's built at a low cost like furniture of Ikea．
D．Because it's made up of pre-cut cardboard．
65Which of the following statements is the advantage of the new drone？A
A．It can land near its target．
B．It has a light motor inside．
C．A crash landing is not acceptable．
D．Its load weighs far more than one kilo．
66．What about Otherlab's Sky Machines can be inferred from the last two paragraphs？B
A．They have been built by the US military．
B．Research is being carried out on their improvement．
C．They are now often stolen and studied by others after deliveries．
D．The electronic materials inside will destroy themselves after use．

Many companies are compressing fresh countryside air into bottles and （73）selling （sell） it online．It sounds like a joke but the idea is to raise （74）awareness （aware） and it provided people （75）with fresh air at a price．One such company is Vitality，（76）which collects air from the Canadian Rockies and compresses it into container．Vitality started the business to sell the canned air as joke gifts at first．（77）However，the products took off in a （78）surprising （ surprise） way then．So，the manager came up with the business idea （79）that they can sell fresh air over the world．The manager of the company has made （80）it clear that China，India and South Korea have become its main markets．
