【解析】

高新技术产业是以电子和信息类产业为“龙头”的产业,产品的科技含量很高,产品更新换代快。我国高新技术产业以高新技术开发区的形式分布,大多依附于大城市,呈现出大分散、小集中的特点。东部高新技术产业发展速度远高于中西部地区。当前,从地区布局上看,我国已初步形成了长江三角洲、珠江三角洲、环渤海地区等各具特色的高新技术产业带。

1烟台纬度较低,气温回升快,三江平原纬度高,气温回升慢,春耕时间比烟台晚;故选:B。

2无人机产业属于高新技术产业,发展我国高新技术产业的最重要条件是科技力量雄厚;目前我国能够实现无人机“空中飞客”航播作业,主要受益于充足的资金和先进的技术,故选项③④符合题意;故选:B。

本题考查了我国黑龙江的农业发展。

【题目】 Your third year of middle school was probably a difficult and busy time. You may have had trouble getting enough sleep. We all know that not getting enough sleep is not good for our health. But it has be found that less sleep could even cause you to have fewer friends, the Guardian reported.

According to researchers from the University of California, people who don't get enough sleep are less willing to socialize(社交)with others. They are simply too tired to go out.

The researchers did a small study. They tested 18 young people who had just had a good night's sleep -as well as tested them again after a sleepless night. The participants watched videos of people with expressions walking toward them. When the person on the video got too "close" to them, they pushed a button to stop the video, which recorded how close they allowed the person to get.

The results showed that the participants kept the person at a further distance if they hadn't gotten enough sleep. They might think the person intruded their personal space. But when the participants got a good night's sleep, they allowed the person to get much closer to them.

According to a lead researcher Matthew Walker, the less sleep you get, the less you want to socialize with others. In turn, other people may think you look strange and stay away from you. This can make you feel lonely and cause you to sleep even less. It becomes a vicious cycle(恶性循环).

So if you want to be a more sociable and popular person, seeping well might help. "One night of good see makes you feel more outgoing and confident." Walker told the Daily Mail.
