绝密★启用前2015年普通高等学校招生全国统一考试(四川卷)理科综合·物理第I 卷 (选择题 共42分)注意事项:必须使用2B 铅笔在答题卡上将所选答案对应的标号涂黑。

第I 卷共7题,每题6分。

每题给出的四个选项中,有的只有一个选项、有的有多个选项符合题目要求,全部选对的得6分,选对但不全的得3分,有选错的得0分。

1.在同一位置以相同的速率把三个小球分别沿水平、斜向上、斜向下方向抛出,不计空气阻力,则落在同一水平地面时的速度大小A.一样大B .水平抛的最大C .斜向上抛的最大D .斜向下抛的最大【答案】A 【解析】根据动能定理:2201122mgh mv mv =-得落地速度v =v 0相同,高度h 相同,故落地速度相同。

选项A 正确。

2.平静湖面传播着一列水面波(横波),在波的传播方向上有相距3m 的甲、乙两小木块随波上下运动,测得两小木块每分钟上下30次,甲在波谷时,乙在波峰,且两木块之间有一个波峰。

这列水面波A .频率是30HzB .波长是3mC .波速是1m/sD .周期是0.1s【答案】C【解析】由两小木块每分钟上下30次知甲、乙的周期相同为T =60/30s=2s ,频率f =0.5Hz ,A 、D 错误;甲在波谷时,乙在波峰,且两木块之间有一个波峰得:3λ/3=3m ,即波长λ=2m ,B 错误;波速v =λ/T=1m/s,,D 正确,选项D 正确。

3.直线P 1P 2过均匀玻璃球球心O ,细光束a 、b 平行且关于P 1P 2对称,由空气射入玻璃球的光路如图。

a 、b 光相比 A .玻璃对a 光的折射率较大 B .玻璃对a 光的临界角较小 C .b 光在玻璃中的传播速度较小 D .b 光在玻璃中的传播时间较短【答案】C【解析】由于细光束a 、b 平行且关于P 1P 2对称,射入玻璃球的入射角相等,由题图几何关系可知光线a的折射角小于b 折射角,根据折射定律:sin sin i n γ=,玻璃对b 光的折射率大,A 错误;由发生全反射的临界角1sin C n =可得:玻璃对b 光的临界角较小,B 错误;根据c v n =知b 光在玻璃中的传播速度较小,C 正确;由于在玻璃中b 的光程d 比a 大,由t =d /v 知b 光在玻璃中的传播时间较长,D 错误,选项C 正确。

Along with other alerting(警报)systems, this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour. Typically, the preferred sleep/wake cycle is delayed in adolescents, which leads to many students not feeling sleepy until much later in the evenings. This typical sleep pattern is usually referred to as the “night owl” schedule of sleep.This is opposed to the “early bird” schedule, and is a kind of disorder where the individualtends to stay up much past midnight. Such a person has great difficulty in waking up in the mornings. Research suggests that night owls feel most alert and function best in the evenings and at night. Research findings have shown that about 20 percent of people can be classified as “night owls”and only 10 percent can be classified as “early birds”—the other 70 percent are in the middle. Although this is clearly not true for all students, for the ones who are true night owls this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.43.

Researchers have found it’s all down to the hormone oxytocin(荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.“Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status,” said Professor Ryan.Generally, people believe that the hormone exytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interaction(互动)such as falling in love or giving birth.But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship.Professor Ryan’s recent experiment used 62 men and women aged 20 to 37.Half of the participants(参与者)received oxytocin. The other half received placebo(安慰剂).After a week, the two groups switched with participants. They went through the same procedure with the other material.Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based ongestures, body language and facial expressions.The results indicated that, after treatment with oxytocin, men’s ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.Professor Ryan thus concluded: “Our experiment proves that the hormone oxytocin can raise people’s abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factor(因素)that are mainly hormonal.”47. What causes men and women to behave differently according to the text?A. Placebo.B. Oxytocin.C. The gesture.D. The social status.48. What can we learn from Professor Ryan’s previous experiment?A. Oxytocin affects our behavior in a different way.B. Our body lets out oxytocin when we are deep in love.C. Our body produces oxytocin when we feel unhappy about other s’ success.D. Oxytocin improves our abilities to understand people’s behavior differences.49. Why did Professor Ryan conduct the recent experiment?A. To test the effect of oxytocin on the ability to recognize social interactions.B. To know the differences between friendship and competition.C. To know people’s different abilities to answer questions.D. To test peopl e’s understanding of body language.50.
