【1】内力作用包括地壳运动、岩浆活动、地震,选项中属于内力作用的是阿尔卑斯山脉的形成,是板块碰撞挤压隆起抬升形成,D对。外力作用表现为外力侵蚀和外力沉积作用。云南石林是流水侵蚀、溶蚀形成,A错。黄河三角洲是河流泥沙沉积形成,B错。张家界雅丹地貌是流水侵蚀形成,D错。

【2】黄土高原千沟万壑的地表形态是流水侵蚀作用的结果,A正确。长江三峡是流水侵蚀形成的,与冰川作用无关,B错误,选B。内蒙古高原上大片戈壁和裸岩荒漠是风力作用的产物,C正确。塔克拉玛干沙漠中的沙丘和沙垄是典型的风积地貌,D正确。

【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

They Just Can’t Help It

My theory is that the female brain is mainly built for empathy — the ability to understand other people — and that the male brain is mainly built for building systems. 【1】 For example, women are more likely to read magazines on fashion and parenting, while men will choose magazines that feature computers and sport.

You may think that these preferences are influenced by the way people are taught to behave when they are growing up. However, this is not the case.

A new study carried out at Cambridge University shows that newborn girls look longer at a face, and newborn boys look longer at a mechanical mobile. 【2】 It has also been observed that girls are better at noticing signs of changes in other people’s feelings. Boys, however, seem to enjoy building toy towers and playing with toys which have clear functions. 【3】 People whose jobs are in the construction industries are almost male. Math and engineering, which require high levels of systems-thinking, are also male-chosen disciplines.

Why do men and women have the difference? Actually women have four times as many brain neurons (神经) that connect the right and left part of their brains as men. Because of it, women have a better ability to multitask than men. 【4】

Men tend to focus on a limited number of problems at a time. They will separate themselves from problems and view tasks as independent from one another.

Some people may worry that I am suggesting one gender (性别) is better than the other, but this is not the case. My theory says that males and females differ in the kinds of things that they find easy, but that both genders have their strengths and weaknesses. 【5】 It is not true. The study simply looks at males and females as two groups, and asks what differences exist, and why they are there.

A. Generally speaking, there are clear differences.

B. Their preference for building systems may change over time.

C. You can see the same kind of pattern in the adult workplace.

D. They will consider many sources of information at the same time.

E. It is important to stress that the female brain may be built more for empathy.

F. That suggests certain differences between male and female brains are biological.

G. Others may think the theory creates a belief of what a particular type of person is like.
