【題目】下圖為我國(guó)某地地質(zhì)剖面示意圖，回答下列問(wèn)題。

（1）甲地和乙地的地質(zhì)構(gòu)造分別是_________________和_________________。

（2）丁地地貌的形成原因是 。

（3）請(qǐng)簡(jiǎn)述丙地地貌的形成過(guò)程。

【答案】（1）向斜(或褶皺) （1分） 斷層（1分）

（2）背斜頂部受張力作用(2分)，巖層破碎，易受外力侵蝕形成谷地(2分)

（3）流水帶來(lái)大量泥沙（2分），當(dāng)水流流出出山口時(shí)，由于地勢(shì)突然趨于平緩（2分），河道變得開(kāi)闊， 水流速度減慢， 河流搬運(yùn)的物質(zhì)逐漸在山麓地帶沉積下來(lái)，形成扇狀堆積地貌。（2分）

【解析】試題分析：

（1）根據(jù)圖中巖層形態(tài)特點(diǎn)，甲地和乙地的地質(zhì)構(gòu)造分別是向斜(或褶皺)、 斷層。

（2）圖中丁地地貌是背斜谷，成因是背斜頂部受張力作用，巖層破碎，易受外力侵蝕形成谷地。

（3）讀圖，丙地地貌是山麓沖積扇。河流在山區(qū)流速快，侵蝕力強(qiáng)，流水帶來(lái)大量泥沙，當(dāng)水流流出出山口時(shí)，由于地勢(shì)突然趨于平緩，河道變得開(kāi)闊， 水流速度減慢， 河流搬運(yùn)的物質(zhì)逐漸在山麓地帶沉積下來(lái)，形成扇狀堆積地貌。

As the development of modern science and technology, more and more electric cars are coming into our lives and become popular.

Electric cars have many advantages. Firstly, they are energy-saved and environmental friendly. They don’t pollute the air because they use electricity to take place of petrol. Secondly, it is easy or safe to drive electric cars. In addition, they make much noise when they are running. Last but not least, electric cars can go on a speed of 120 kilometers an hour.

In my opinion, our government should take measure to support the production of electric cars and encourage people to using them. If possible, people should use electric cars in order to make our world clean and better in the future.

【題目】【2016屆江西上高縣第二中學(xué)高三上學(xué)期第二次月考】

Before your child's final exam: and the graduation announcements, you face a significant task together: choosing the right college or university. There is no "one size fits all" approach to selecting a college—it's a very personal process for most teenagers. Consider a wide range of factors to help your child make the best possible choice.

Discuss with your child her post-high school choices, such as college, finding work or starting a business, or joining the army. If you determine together that college is the best choice for your child, talk about the importance of college, and her longer-term goals by going to college.

Talk to your child about what she thinks is important in a college experience and share your opinions as well. Identify the issues that will directly impact her college choice, such as her grades, test scores and family finances. Then make a list of the key criteria for her dream school, including factors such as the school's location, its size, the types of program:, the after school activities available and the type of financial aid available.

Prioritize the item: on your child's list, at least to the extent of sorting it into "must-haves," "highly desirable" and "nice-to-have" categories. Put these factors into an online search engine specifically designed to identify colleges and universities that best meet your criteria, such as that offered by CollegeBoard.org. Start with the most important criteria, then experiment with additional factors to narrow the search results to a number you can work with, as 10 or 20 different schools.

Use the search results as a guide to further focus your college search. Research each school by reviewing its website, requesting information directly from the school and attending local presentations about the school.

【1】The underlined word "prioritize" in Paragraph 4 probably means "______".

A. list in order of importance B. write down

C. add to D. do research into

【2】What can we learn from the passage?

A. It's better to decide the college for your child.

B. It's necessary to take your child's opinion into consideration.

C. There is a "one size fits all" way to select a college.

D. An online search engine is of great help to you.

【3】What's the author's purpose of writing the passage?

A. To argue B. To persuade

C. To introduce D. To amuse

【4】Which of the following shows the structure of the passage?
