    【题目】2015年在我国某大都市郊县的苹果文化节上，市民们见到树体矮小、幼童伸手可摘的苹果树。“矮化密植”技术使果树树冠缩小,结果更早、更多、含糖量更高。据此回答下列问题。

    【1】与传统种植方式相比，“矮化密植”技术的优势在于

    A．①③ B．①④ C．②③ D．②④

    【2】近年来都市郊县农村纷纷举办集商贸、旅游一体的“文化节”，该模式主要基于

    A．政策支持、交通改善 B．民俗传统、假日增多

    C．技术进步、环境改善 D．商品丰富、价格优惠

    【3】该地苹果文化节上还引入“互联网+”的形式，大量苹果微店的开通，此举

    A．宣传了苹果文化，提升了市民素质 B．拓展了销售市场，提高了经济收益

    C．应用了网络技术，提升了政府业绩 D．便利了产销沟通，提高了产品价格

    【答案】

    【1】B

    【2】A

    【3】B

    【解析】

    试题分析：

    【1】从材料“矮化密植技术使果树树冠缩小,结果更早、更多、含糖量更高”中可知，“矮化”指的是改良了作物品种，“结果含糖量更高”说明充分利用了光热条件，B正确；该技术与提高土壤肥力无关，只有加大科技投入才能改良品种。

    【2】郊县农村举办商贸、旅游一体的“文化节”主要基于政策支持和交通条件的改善，A正确；近年来举力的文化节并不是民俗传统、与技术无关，都市里的商品更丰富。

    【3】开通苹果微店的主要目的是拓展销售市，提高经济效益，B正确；苹果微店并与提升市民素质和政府业绩无关，也不会提高产品价格。

    【题目】阅读理解

    阅读下列短文,从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

    Being physically active three times a week reduces the odds of being depressed by about 16%, according to new UCL research carried out as part of the Public Health Research Center.

    The study, published in JAMA Psychiatry, found a two-way relationship between depression and physical activity. People who increased their weekly activity reported fewer depressive symptoms but those with more depressive symptoms were less active, particularly at younger ages.

    Researchers followed 11,135 people born in 1958 up until the age of 50, recording depressive symptoms and levels of physical activity at regular intervals in adulthood. They found that each additional activity period per week reduced odds of depression by 6%. In England 19% of men and 26% of women are currently classed as “inactive”, and this study suggests that activity could significantly improve their mental as well as physical health.

    “Assuming the association is causal, physical activity has a protective effect against depression. If an adult between their twenties and forties who isn’t physically active became active 3 times per week, they would reduce their risks of depression by about 16%.” says Dr. Snehal of the UCL Institute of Child Health, lead author of the study.

    Professor Mark, Director of the Public Health Research Center, said, “Many people are already aware of the benefits of physical activity on their general health, but now we are seeing more evidence that suggest it also has a positive effect on a person’s mental well-being. The latest research highlights just how important it is to ensure that people are working and living in environments that allow them to be both physically active and mentally healthy.”

    【1】What is the author’s purpose in writing the passage?

    A. To tell us a fun story about how to protect us against depression.

    B. To introduce a research on the link between activity and depression.

    C. To persuade readers to increase their weekly activity.

    D. To describe the disadvantages of physical activity.

    【2】According to the second paragraph, if people increase their weekly activity, ______.

    A. their depressive symptoms will be fewer

    B. their depressive symptoms will be more

    C. they will become much younger

    D. they will become more depressive

    【3】Which of the following statements is TRUE according to the passage?

    A. Dr. Snehal thinks it important to be both physically and mentally healthy.

    B. The research shows men are more active in physical activities than women.

    C. Adults who insist on physical activity will reduce depression completely.

    D. Increasing physical activities can free people from depression in a way.

    【4】The author shows his view mainly by_______.

    A. doing research

    B. comparing and contrasting

    C. trying on himself

    D. discussing and summarizing
