正确答案: B

不正确，不得歧视犯错误学生

题目：中学生熊某曾经偷拿过同学的财物，班主任总是以此为由，不让他参加班级活动，该班主任的做法（ ）。

解析：熊某曾经是有偷窃的不良行为，但作为老师，对不良行为的未成年人应当加强教育、管理，不得歧视。本题中，班主任不让他参加班级活动就是歧视犯错误的学生。故本题选B。

[单选题]"说出牛顿定律"属于加涅的学习结果分类系统的( )。

言语信息

解析：加涅根据学习结果把学习分为五类，分别是言语信息、智慧技能、认知策略、动作技能和态度。言语信息是指学生掌握的是以言语信息传递（通过言语交往或印刷物的形式）的内容或者学生的学习结果是以言语信息表达出来的，解决的是"是什么"的问题：智慧技能的学习要解决"怎么做"的问题，以处理外界的符号和信息，又称过程知识，比如如何把小数转化为分数：认知策略是学习者用以支配他自己的注意、学习、记忆和思维的有内在组织的才能，用以支配和控制学习过程：态度是通过学习获得的内部状态：运动技能卫称为动作技能。此题"说出牛顿定律"，解决的是"是什么"的问题，故选D。

[单选题]We must improve the farming method________we may get high yields.

in order that

解析：本题考查连词辨析。句意为“我们必须改进耕作方式以获得高产量”。in order that表示“以便，为了”，后面接从句作目的状语，故本题选B。in case引导目的状语从句时表示“以免，以防”；now that“既然，由于”；even if“即使，尽管”。A、C、D三项均不符合句意。

[单选题] After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll could have been much worse. More than 60 people died in this earthquake. By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25,000 victims. Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 am on a holiday, when traffic was light on the city's highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes. Despite the good news, civil engineers aren't resting on their successes. Pinned to their drawing boards are blueprints for improved quake resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place. In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations, The most recent designs give buildings brains as well as concrete and steel supports. Called smart buildings, the structures respond like living organisms to an earthquake's vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction. The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.

One reason why the loss oflives in the Los Angeles earthquake was comparatively low is that ________.

improvements had been made in the constructions of buildings and highways

解析：1.细节题。根据短文第三段第二句“…changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes.”可知是因为建筑法规在20年内的改变，使地震中的伤亡人数相对不高。故选项D正确。 2.细节题。根据短文第五段最后一句“When the ground shakes and the building tips forward，the computer would force the building to shift in the opposite direction.”可知当地面晃动，建筑物向前倾斜时，电脑会迫使它向相反的方向改变，从而保持平衡。故选项A正确。 3.细节题。文章最后一段指出“The new smart structures could be very expensive to build. However，they would save many lives and would be less likely to be damaged during earthquakes.”可知这种新型的智能结构虽然昂贵但是很值得建造。选项A、C文中没有提到，选项D的表述与原文不一致．故选项B正确。 4.推断题。根据短文第五段可知，过去人们认为建筑材料对减少地震损失很重要，但那是以前的方法，排除选项A、B。而现在重点强调的办法是减少地面震动。选项D文章没有提及，故选C。 5.主旨题。纵观短文可看出作者是通过描述发生在洛杉矶的地震来指出抗震技术的提高。选项A是说地震结果的比较，不是文章重点，选项B、C与原文表述不符，故选项D正确。

[单选题]She won't be available between 6 and 8,for she_______an important meeting.

will be having

解析：本题考查时态。句意为“6点到8点这段时间她不在，因为那时她正参加一个重要的会议”。由won，t可判断前半句是一般将来时；后半句解释原因，表示在6点到8点那个时间段正在发生的事情，所以用将来进行时。故本题选D。
