第二步：添加细节，文意更丰满，表达更亮眼
为了使内容更充实，我们需要对要点进行适度拓展，让要点在内容上和形式上更丰满。要点1－①可增加as引导的定语从句“随着中秋节临近”；要点1－②可以增加“非常荣幸代表我们班”。
拓展要点1－①：随着中秋节临近，我们班将于本周五晚8：00在演讲大厅举办庆祝会。(as)
As_the_Mid­Autumn_Festival_is_approaching,_our_class_will_hold_a_celebrating_party_in_the_lecture_hall_at_8：00_pm_this_Friday.
拓展要点1－②：非常荣幸代表我们班写信邀请您参加它。(on behalf of)
It's_a_great_honour_to_write_to_invite_you_to_attend_it_on_behalf_of_our_class.
第三步：连句成文，排语句顺序，重衔接过渡
本篇写作整体可采用“三段式”作文结构。根据语篇表达中的逻辑关系，可在介绍活动安排时添加连接词 at the beginning， what's more巧妙地将要点衔接起来，让文章显得顺畅自然。
Dear_Professor_James，
As_the_Mid­Autumn_Festival_is_approaching,_our_class_will_hold_a_celebrating_party_in_the_lecture_hall_at_8：00 pm this Friday. It's a great honour to write to invite you to attend it on behalf of our class.

理清文体结构之(十一)　说明文之事物类——抓说明对象，根据事物特点巧解题
事物类说明文一般在首段给出说明对象，然后从几个方面对事物进行客观说明。因此，该类文章的行文结构一般较为简单，阅读时不要拘泥于细枝末节，浏览完全文后，带着题干中的关键词，再次跳读原文查找答案出处，认真比对，从而得出正确答案。

[1]There’s a new frontier in 3D printing that’s beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn’t stopping there.
Food production
[2]With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to “re­create forms and pieces” of food that are “exactly the same，” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D­printed, rather than farm to table.
Sustainability (可持续性)
[3]The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae (藻类) and grass to replace the familiar ingredients (烹饪原料).3D printing can reduce fuel use and emissions. Grocery stores of the future might stock “food” that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.
Nutrition
[4]Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday’s bread from the supermarket, you’d eat something baked just for you on demand.”
Challenges
[5]Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste (糊状物) before a printer can use them, and the printing process is quite time­consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high­end restaurants.
1.读首段抓说明对象
本文在首段首句介绍了3D打印技术的新领域——打印食物。
2.览标题，看行文结构
本文从Food production, Sustainability, Nutrition, Challenges 四个方面介绍了3D打印食物的优缺点。
3.标题眼，找特点，比对定答案
标出题干中的关键词，再次跳读原文，查找事物特点，认真比对，得出答案。

[由题眼找特点，比对定答案]
