A Language Programme for Teenagers

Welcome to Teenagers Abroad! We invite you to join us on an amazing journey of language learning.

Our Courses

Regardless of your choice of course, you’ll develop your language ability both quickly and effectively.

Our Standard Course guarantees a significant increase in your confidence in a foreign language, with focused teaching in all 4 skill areas----speaking, listening, reading and writing.

Our Intensive Course builds on our Standard Course, with 10 additional lessons per week, guaranteeing the fastest possible language learning (see table below).

Evaluation

Students are placed into classes according to their current language skills. The majority of them take on 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 take 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 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.

问答题

某建设工程监理公司受建设单位的委托,对一栋综合楼进行施工监理。该综合楼地上17层,地下2层,1~4层为裙房,5层以上为主楼办公楼,建筑总高度82m,主楼层高4.2m,室内外高差0.3m。该工程包括供配电及动力系统、电气照明系统、防雷及保护接地系统、火灾报警及消防联动控制系统和弱电系统。
(1) 供配电系统:该工程内供电负荷属一级负荷,采用树干式与放射式相结合的方式。
(2) 自备发电机系统:该工程在地下二层发电机房安装一台应急柴油发电机组。
(3) 防雷及保护接地系统:采用联合接地方式,利用40mm×4mm热镀锌扁钢将柱基承台钢筋网、柱基钢筋连接起来构成等电位接地网络,采用焊接连接,接地电阻不大于1Ω;利用结构柱内主钢筋及钢构件作为引下线,两根大于φ16mm的为一组,柱子上下端各预埋100mm×100mm×8mm的钢板,用于柱子内主筋与避雷带连接的转换;屋面采用25mm×4mm热镀锌扁钢作为避雷带,沿女儿墙四周敷设,在屋面组成不大于10mm×10m(或12mm×8m)的避雷网格,所有高出屋面的各种金属构件均与避雷带焊接连通,在屋顶最高点处设避雷器;每层建筑物外墙连续梁内钢筋与楼层钢筋焊接成一体形成均压环,并与引下线可靠连接,45m及以上外墙的幕墙金属框、金属扣板、门窗、构件、外墙栏杆与均压环焊接以防侧击雷;所有进入建筑物的金属管道和电缆的金属外皮在入户处均与接地装置连接,垂直敷设的金属管道及金属物体的顶端和底端均与防雷装置连接。由联合接地体的接地环网引上的接地线采用镀锌扁钢或铜芯线,引至地下室或底层弱电间后再引至弱电机房等处。各种设备用房接地采用镀锌扁钢或铜芯线在引下线处与桩基钢筋焊接。
请根据上述条件,回答下列问题。
