题目内容

【题目】青藏高原形成一种特殊的高原气候,但利用大棚技术使得拉萨的瓜果蔬菜供应充足。据此完成下列各题。

【1】拉萨利用大棚技术种植瓜果蔬菜,主要是改善了当地的

A.热量条件 B.光照条件

C.水分条件 D.土壤条件

【2】拉萨原来不产西瓜,引种后发现:直接“铺”在地上生长的西瓜长不好,只有将西瓜藤蔓架空,西瓜“挂”着才能结果(如图所示)。西瓜“挂”着的原因是

A.大棚内的地面温度比空气温度低,不有利于西瓜的发育成熟

B.可以减少叶子对西瓜的遮掩,增强光照,促进光合作用

C.可以充分利用立体空间,节省土地、节省大棚面积,减少农业投入

D.土壤的湿度不够、干燥,直接"搁"在地上,容易使西瓜的水分蒸发

【答案】

【1】A

【2】A

【解析】

试题分析:

【1】塑料大棚起到了保温作用,主要是改善了当地的热量条件,A对。该地光照充足,不需要改善光照条件,B错。青藏高原上水分条件较好,主要不利因素是热量缺乏,C错。塑料大棚技术不能改变土壤条件,D错。

【2】青藏高原海拔高,大棚内地面温度低,不利于西瓜的生长发育。而棚内空气受温室效应影响,温度高,有利于西瓜的生长,A对。与增强光照,促进光合作用无关,B错。充分利用立体空间,节省土地、节省大棚面积,不是主要原因,会增加农业投入,C错。大棚内,保温,也能保湿。土壤的湿度不够、干燥,不是“挂”着的原因,D错。

【题目】下面文章中有5个段落需要添加首句。请从以下选项(A、B、C、D、E和F)中选出符合各段落的首句。选项中有一项是多余选项。

A. Question relentlessly(持续地).

B. Create a challenge.

C. Expect things to be fun.

D. Add variety to your life.

E. Connect to what you already know.

F. Absorb other people’s enthusiasm.

The more I observe brilliant people, the more I notice that one distinguishing characteristic they have is immense curiosity. How does curiosity contribute to someone’s brilliance? It gives you a fresh perspective. Curious people can see something that many other people can’t. It gives you fresh ideas. Using the term from The Medici Effect, curiosity gives you intersection experience where concepts from different fields collide with one another and produce fresh ideas. Since curious people get more intersection experience, they consequently get more fresh ideas.

Now that we’ve seen how important curiosity is, how can we develop it? Here are some tips:

【1】 Rather than expecting things to be boring, expect them to be fun. This small change in your mindset(心态) can make a big difference. Once you do it, it will be much easier for you to find the fun side of practically anything.

【2】 Often something seems boring because it’s delivered poorly. That’s perhaps one thing that makes great teachers great: they can connect their students to the fun side of what they’re teaching. So one way to develop your curiosity is to watch the talks of those who are enthusiastic about their fields. Don’t just absorb their knowledge; absorb their energy too.

【3】 By creating a challenge, you will want to prove to yourself (and perhaps to others) that you can make it. One good way to do that is by creating a project: building something real out of what you learn. Another way is to create a contest with your friends to find out who can do something faster or better.

【4】 Things will be more exciting if you can connect what you’re learning to what you already know. Why? Because that improves your understanding of the world and allows you to see new possibilities you’ve never realized before.

【5】 Avoid boredom and find new possibilities by exploring new topics. Read books in new types. Meet people with different professions.

The core is simple, actually. All the advice above can be summarized to just one: make things fun.
