德阳高考成绩查询【二】:德阳高考第一天直击:秩序井然 从容应考

德阳高考第一天直击:

秩序井然 从容应考

昨(7)日,是今年高考第一天。全市1.8万余名考生共同赴考,总体情况平稳、良好,未发生重大违规违纪行为,受到了教育部高考督察组的高度评价。

镜头一:考场秩序井然

早上8点多,记者在德阳中学考点看到,考生或结伴,或在父母陪同下,陆续赶到考点,精神面貌良好。领队老师早早地等在校门口,为考生发放准考证。

为确保高考顺利进行,相关部门已提前安排执法人员加强对考点周边环境、交通和卫生的监督管理。交警部门对部分路段实行了临时交通管制,禁止一切机动车辆进入;市区200辆高考服务警车随时待命,及时帮助解决考生的紧急情况和危难事宜,确保考生准时到达考点。

尽管考点外人员众多,但并没有出现嘈杂混乱的情况,整个考场秩序井然。随着考试时间临近,考生们开始进入考场,考场外只剩下翘首企盼的家长和默默祝福的老师。 镜头二:安检顺利进行

今年高考首次实行安检,每个考生都必须接受安全检查后才能入场,手机、手表、手镯等一切与考试无关物品均不能带入考场。对此,有个别家长曾表现出些许担忧,不过,

记者在现场看到,安检工作正有条不紊地进行,工作人员用专门配发的金属探测刷对学生逐一检查。安检的过程很快,每名考生一般只需要20秒钟左右,丝毫不影响考试正常进行。

据市教育局有关负责人介绍,安检旨在确保考试安全和公平公正,考前,已专门对监考老师和考生进行了培训,消除了考生的紧张心理。按照规定,安检时间为15分钟,不过从各考点的实际情况来看,大部分都在10分钟左右就完成了。

镜头三:家长送考不陪考

记者在市区一些考点发现,今年送考家长仍然不少,不过更加理性,大多数家长在开考后就相继离开,而不是像以往一直守候在考场外。

一位家长表示,“家长在考场外等候,反而容易给孩子造成压力,影响孩子发挥。”旁边一位家长也附和道:“的确,孩子虽然嘴上说不紧张,其实心里难免还是会有些紧张,这段时间我们都非常注重自己的言行,生怕增加孩子的压力,尽量创造一个轻松的氛围,让孩子有一个良好的心态。”一些家长还拿出照相机为孩子拍照,仿佛这不是要进行高考,而是一次亲子活动,一位父亲告诉记者,高考是孩子人生中的一件大事,

他想把孩子参加高考时的样子记录下来,好好珍藏。 考场外,两位白发苍苍的老人不时地往里瞅,“我们想

来看看孙子,给他打打气,”老大娘喻慎芳说,“孩子的父母都在外地打工,这些年他一直跟着我们生活,这孩子很懂事,学习也很用功,我们想看着他进考场。”

四川省德阳市2016高考英语一轮阅读类选练6

阅读下列四篇短文,从每小题后所给的A,B,C或D四个选项中,选出最佳选项。

For those who are tired of doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app (application) . Strange though it may seem—“my wife already does that”was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week—Samsung is just one of many appliance makers racing to install (安装) a large number of internet- connected features in machines in an effort to make them“smart. ”

Last year, it was a refrigerator that tweeted. This year, it’s Wi- Fi- enabled laundry machines and fridges that can tell you when your groceries are going bad.

The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owner is at work or on the bus. Samsung says it’s not just something new—the app connection actually has some practical uses.

“If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when you come home, so your clothes are refreshed and ready to go, ”said spokesperson Amy Schmidt.

The company also says that with electricity rates (电价) varying depending on the time of day, more control over when the machines are used can help save money.

Perhaps, but what they will probably really accomplish is what all good technologies do—enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV.

1. What can be inferred from the common response of the attendees at the CES?

A. The machine will be a big success. B. Their wives like doing the laundry.

C. The machine is unrelated to their life. D. This kind of technology is familiar to them.

2. What can we learn about the new laundry machines?

A. They can tell you when your clothes need washing.

B. They can be controlled with a smartphone.

C. They are difficult to operate.

D. They are sold at a low price.

3. We can conclude from Samsung’s statements that .

A. the app connection makes life easier B. it is better to dry clothes in the morning

C. smartphones can shorten the drying time D. we should refresh clothes back at home

4. What is the main idea of the last paragraph?

A. The laundry should be frequently checked. B. Lazy people like using such machines.

C. Good technologies also cause problems. D. Television may help do the laundry.

【参考答案】1—4、DBAC

社会生活类----阅读理解。

Two friends have an argument that breaks up their friendship forever, even though neither one can remember how the whole thing got started. Such sad events happen over and over in high schools across the country. In fact, according to an official report on youth violence, “In our country today, the greatest threat to the lives of children and adolescents is not disease or starvation or abandonment, but the terrible reality of violence”. Given that this is the case, why aren’t students taught to manage conflict the way they are taught to solve math problems, drive cars, or stay physically fit?

First of all, students need to realize that conflict is unavoidable. A report on violence among middle school and high school students indicates that most violent incidents between students begin with a relatively minor insult (侮辱) . For example, a fight could start over the fact that one student eats a peanut butter sandwich each lunchtime. Laughter over the sandwich can lead to insults, which in turn can lead to violence. The problem isn’t in the sandwich, but in the way students deal with the conflict.

Once students recognize that conflict is unavoidable, they can practice the golden rule of conflict resolution (解决) : stay calm. Once the student feels calmer, he or she should choose words that will calm the other person down as well. Rude words, name- calling, and accusations only add fuel to the emotional fire. On the other hand, soft words spoken at a normal sound level can put out the fire before it explodes out of control.

After both sides have calmed down, they can use another key strategy (策略) for conflict resolution: listening. Listening allows the two sides to understand each other. One person should describe his or her side, and the other person should listen without interrupting. Afterward, the listener can ask non- threatening questions to clarify the speaker’s position. Then the two people should change roles.
