To celebrate its new building set, LEGO made a full-size real Koenigsegg car with almost 328,000 LEGO pieces. They invited a professional test driver to drive it on a famous race track. This activity was mainly for public promotion.It also broke the world record for the fastest LEGO car. Its speed was over twice the old record of 50 kilometres per hour.

This life-sized car is a great technical success. A group of builders spent 9,400 hours finishing the project. It looks so true to life that people would mistake it for a real sports car instead of a plastic toy built fromLEGO bricks.

The project was full of challenges. The team planned to finish it within seven and a half months. Their goal was to make the car run as fast as 100 kilometres per hour. They also added many movable body parts to copy the special mode of the real Koenigsegg car. It was no longer just a model, but a fully drivable vehicle.

1.1.What was the main reason for LEGO to build the real car?

A To test a new electric motor.

B To promote their new building set.

C To break a world record.

D To show off their design skills.

解析：选B。B 细节理解题。文章第一段明确提到“This activity was mainly for public promotion”，说明制造这辆真车主要是为了推广其新的积木套装。选项A“测试新的电动机”在文中未作为目的提及，文中仅说车辆由电动机驱动。选项C“打破世界纪录”是这次活动带来的结果，但并非主要原因。选项D“炫耀设计技巧”虽然文章末尾提到展现“Build For Real”精神，但主要目的依然是宣传推广。故选B。

2.2. What can we know about the car’s appearance?

A It looks quite real.

B It looks heavier than a real car.

C It is made of metal only.

D It is painted in simple colours.

解析：选A。A细节理解题。第二段中的“It looks so true to life that people would mistake it for a real sports car”直接说明这辆车的外观极其逼真，会被误认为是真车。选项B“看起来比真车更重”在文中没有依据，仅给出整车1800公斤，并未与真车比较。选项C“仅由金属制成”错误，因为车身由乐高积木搭建，内部才有金属框架。选项D“涂装颜色单一”文中完全没有提及，因此A正确。

3.3. What was the project like for the builders?

A Easy and quick.

B Simple and boring.

C Full of difficulties.

D Short and relaxing.

解析：选C。C细节理解题。根据文章第三段第一句“The project was full of challenges.”可知，这个项目充满了挑战，即充满困难。选项C“Full of difficulties”是“full of challenges”的同义替换。建造者们花费了9400小时，计划七个半月完成，目标是让车速达到100公里/小时，还要添加可移动部件，这些都说明项目既不简单也不轻松，因此A（简单快捷）、B（简单无聊）、D（简短轻松）均与原文不符。故选C。

4.4. What powered the LEGO sports car?

A Petrol engine.

B Electric motor.

C Human power.

D Wind power.

解析：选B。B细节理解题。最后一段中直接说明“It runs on an electric motor”，明确这辆乐高跑车由电动机驱动。选项A“汽油发动机”、选项C“人力”和选项D“风力”在文中均未出现，因此B正确。

5.5. What is the main idea of the text?

A The history of LEGO car models.

B History of car races.

C New LEGO brick materials.

D A fast full-size LEGO car.

解析：选D。D主旨大意题。全文围绕乐高用近32.8万块积木打造出一辆可驾驶的全尺寸跑车展开，介绍了其逼真外观、建造挑战和速度成就等，核心是这辆“快速的、全尺寸的乐高汽车”。选项A“乐高汽车模型的历史”和选项B“赛车的历史”在文中均未涉及。选项C“新的乐高积木材料”也未提及，文中用的就是常规乐高积木。因此D最能概括全文主旨。
