【题目】Two self-driving buses have rolled out on to the public roads of Helsinki,Finland,in the first trials【1】its kind. The Easymile electric mini-buses,able to carry up to 12 people,will run on the open roads of Helsinki's Hernesaari district.“【2】is no more than a handful of these kinds of street traffic trials taking place.”Harri Santamala,test project lead said.

Finland【3】(become) a top leader m automated technology development and testing recently because,unlike most of the rest of the world,Finnish law does not require vehicles on public roads to have a driver.Obstacles【4】 (meet) in many other firms and research groups that looked to test autonomous vehicles in the US and Europe have been removed.

Operating such a system has proven a(n)【5】(true) difficult challenge.The city traffic will provide hard points for the buses to overcome,since they have to work【6】common cars and other road users may not be predictable. The buses have a maximum speed of 40km/h but will travel at an average speed of 10km/h,thus【7】(lead) them to be slow-moving vehicles during rush【8】(hour).

Helsinki is several years into its 10-year plan to make car ownership pointless through point-to-point "mobility on demand" systems.Two years【9】,the smart bus service Kutsuplus had been shut down due to costs and the low volume of passengers.【10】is expected to happen that small automated buses could make a difference when present human-operated transport has proved inefficient with government funds.

【解析】这篇短文介绍在芬兰首都出现了两辆自动驾驶公共汽车，以及这类汽车运行的一些困难。

【1】考查介词。在芬兰首都赫尔辛基的公共道路上，有两辆自动驾驶的公共汽车已经上路，这是同类车中的第一次。根据句意可知，此处表示所属关系，用of表示。故填of.

【2】考查固定句型。在这类街头交通试验中，只有为数不多的几个。根据句意可知，此句中表示“有”，用there be句型。故填There.

【3】考查句子时态。芬兰最近成为了最高的自动技术研发和测试的领导者。根据句中从句的时态可知此处应该用现在时，并结合语境可知应该用现在完成时。故填has become.

【4】考查句子时态。句意：在许多其他公司遇到的障碍，以及在美国和欧洲测试无人驾驶汽车的研究小组已经被移除。根据句意可知，该句应该用一般过去时，meet过去式为met.故填met.

【5】考查副词。句意：操作这样一个系统已经被证明是一个真正困难的挑战。该处修饰后面的形容词difficult，应该用副词修饰形容词。故填truly.

【6】考查副词。句意：城市交通将为公共汽车提供难以克服的困难，因为它们必须在公共汽车和其他道路使用者可能无法预测的地方工作。根据分析句子可知，work后面应该是状语，此处应该用where引导状语从句。故填where.

【7】考查现在分词。句意：公共汽车的最高时速为40公里，但将以每小时10公里的速度行驶，因此在上下班高峰期将会是缓慢行驶的车辆。此处是结果状语，lead与其逻辑主语（句子主句）之间是主动关系，应该用现在分词做状语。故填leading.

【8】考查名词。句意：公共汽车的最高时速为40公里，但将以每小时10公里的速度行驶，因此在上下班高峰期将会是缓慢行驶的车辆。此处表示具体的高峰期，hour是可数名词，应该用复数形式。故填hours.

【9】考查副词。句意：两年前，由于成本和乘客数量的减少，智能的公共汽车服务Kutsuplus被关闭了。Ago用于一般过去时，before/earlier用于完成时，根据句子时态had done，此处表示的两年前应该用before/earlier.故填before/earlier.

【10】考查it。句意：人们预计，当现有的人力交通工具在政府资金中被证明效率低下时，小型自动巴士可能会产生影响。句中设空处应该是形式主语，真正的主语是that从句，英语中用it做形式主语。故填it.
