A brand new _Minecraft_ game will be story-driven.
The new series of “_Minecraft: Story Mode_” will be set in the world of _Minecraft__,_ but it will feature an original story that combines new characters with familiar themes. It is driven by player choice. It will be a separate standalone product.
The decision to make the new game community-driven is potentially brilliant. It’s interesting that feedback from the community is going to be brought into _Minecraft: Story Mode_. In a way, it echoes what _Minecraft_ is. It is a user-generated world.
It’s likely that there already have been gamers on _Minecraft_ fan blogs. They have come up with theories as to how the universe was created. There could be lots of contradictory things there. But from a marketing standpoint, it makes all the sense in the world for the community of “you guys are going to write this.”
_Minecraft_ first came out in 2009 and is probably due for an evolution of some sort. _Story Mode_ seems like a natural next step. A dedicated fan base has very high expectations. It will be satisfied with the story it is developing.
There will be challenges, however. _Minecraft_ does not follow what the game industry is used to working with. It will be a completely different development scenario. It is a world with no story and starting from the beginning. As long as the _Minecraft_ story is popular and successful, that might be OK.

PASSAGE 1 (教材课文原文)
"The printer did not always manage to spread the plastic evenly, making some of the ribs of the honeycomb structure of the block uneven," reported ARN (Australian Radio Network) to the surprise of no one who has used a 3D printer. But the architects remain optimistic. The first few printed blocks are meant to be test pieces as they improve the process.
It takes about a week to print a 3-meter high block right now. The project's leaders hope to eventually get that down to two hours and finish the first of 12 rooms in a year, and the entire house in less than 3 years.
Ultimately, 3D Print Canal House is an architectural research project, one that is very much being conducted in the public eye: you can actually buy tickets to visit the construction site for 2.50 Euros.
The top floors will become more ornate, for example, as newer techniques are incorporated. They'll explore the possibilities of 3D printing, like the honeycomb walls or an entire room recycled, redesigned, and built anew. Nobody's going to move into a 3D printed house soon, but, if anyone ever does, something might be learned from this experiment by the canal.

king features and benefits first. It's often not enough to just list the features of a product as your audience may not always understand them. Use {A. description; B. descriptive; C. described} language to convey how any one feature will benefit the buyer and {A. how; B. what; C. who} purchasing the item will make the consumer's life easier. Potential buyers want to know what the product will do for them.Second, use clear and decisive language. It's important when writing product descriptions to be concise. Use common language and terms that are easy to{A. remember; B. write; C. understand}. Clearly describe the product without{A. to get; B. get; C. getting} too technical or boring so the reader stays engaged. Last but not the least, include a call-to-action. The best product descriptions always{A. ask to; B. ask for; C. asking} a sale. Be creative and encourage the potential buyer to purchase your product by telling them exactly how to do it.
某工业园区洁净室的空气洁净度等级为(N)6级。室外大气尘浓度(大于等于0．5μm)为30×104pc／L，室内单位容积发尘量G=1．8×104pc／(min.m3)，采用一次回风系统，回风比S=0.8粗效过滤器效率η粗(大于等于0．5μm)，中效过滤器效率η中=300(大于等于0．5μm)。考虑不均匀分布系数φ=1．1，按不均匀分布计算理论。换气次数nv=60.5h-1，安全因数a=0．6，末级空气过滤器的效率(大于等于0．5μm)必须大于________。已知：(0．1／0．1)=1；(0．1／0．2)2.08=0．2365；(0．1／0．3)2.08=0．1018；(0．1／0．5)2.08=0．03517。
