黑龙江省双鸭山市第一中学2017-2018学年高二下学期英语4月月考试卷
A great invention by an 18-year-old high school student grew out of a simple problem most teenagers meet with.
“I'm a teenager and I have a cellphone and my cellphone battery always dies,so I was really looking for a way to improve energy storage,” Eesha Khare said on Tuesday. “That's how I came across the super capacitor.”
The teenager who came from California, and graduated from high school last week,won a $50,000 prize on May 17,2013 at the Intel International Science and Engineering Fair for creating a device that can store enough energy to charge a cellphone in 20 to 30 seconds.
“It charges very quickly and can store a lot of energy,” Khare said. “The cool thing is that it's a lot thinner than one strand of hair.”
Khare hasn't used her invention to recharge a cellphone yet,but she used it to power a light-emitting diode (LED) in order to show its capability(容量). If used on cellphones,the supercharger would slide on to the phone's battery to juice it up in a matter of seconds. The technology isn't available to consumers yet,and it could be years until it is.
At an Intel event in Phoenix,Khare won the Intel Foundation Young Scientist Award,taking second place overall in the world's largest high school science research competition. She beat out more than 1,600 finalists from 70 countries. She said that she has been approached by several companies to continue her research,but she is now focused on attending Harvard University in autumn.
“Right now,just my education,but hopefully we'll see what happens in the future,” she said about her plans. “I have a lot of interests,so we'll see what I do in the future.”

Evaluation
Students are placed into classes according to their current language skills. The majority of them take an online language test before starting their programme. However, if this is not available, students sit the exam on the first Monday of their course.
Learning materials are provided to students throughout their course, and there will never be more than 15 participants in each class.
Arrivals and Transfer
Our programme offers the full package—students are taken good care of from the start through to the very end. They are collected from the airport upon arrival and brought to their accommodation in comfort. We require the student's full flight details at least 4 weeks in advance.
Meals/Allergies(过敏)/Special Dietary Requirements
Students are provided with breakfast, dinner and either a cooked or packed lunch (which consists of a sandwich, a drink and a dessert). Snacks outside of mealtimes may be purchased by the student individually.
We ask that you let us know of any allergies or dietary requirements as well as information about any medicines you take. Depending on the type of allergies and/or dietary requirements, an extra charge may be made for providing special food.
