[单选题]There is every sign that new Asian immigrants are willing to________with Americans.

assimilate

解析：本题考查动词辨析。句意为“种种迹象表明新一代亚洲移民乐意被美国人同化”。oblige“迫使，强制”，absorb“吸收，吸引……的注意”，assimilate“使同化，吸收”，stabilize“稳定，使安定，使坚固”。根据句意可知本题选C。

[单选题] People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking; they try to find a solution by trial and error. However, when all these methods fail, the person with a problem has to start analyzing. There are six stages in analyzing a problem. First the person must recognize that there is a problem. For example, Sam's bicycle is broken, and he cannot ride it to class as he usually does. Sam must see that there is a problem with his bicycle. Next the thinker must define the problem. Before Sam can repair his bicycle, he must find out the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific. Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully. After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels. Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels. Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. In short, he has solved the problem.

By referring to Sam's broken bicycle, the author intends to ________.

tell us how to solve a problem

解析：1.主旨题。短文以Sam出故障的自行车为例，讨论了解决问题的六个方法步骤。因此符合文章大意的题目应是：Possible Ways to Problem-Solving。故选B。 2.细节题。根据短文各段首句可知分析问题的步骤有：First the person must recognize that there is a problem(认识到问题的存在).Next the thinker must define the problem(定义问题).Now the person must look for information that will make the problem clearer and lead to possible solutions (分析问题).After studying the problem，the person should have several suggestions for a possible solution(提出解决：问题的建议).Finally the solution is tested(检验解决方法)。故可知只有选项D不符合原文。 3.细节题。作者以Sam出故障的自行车为例告诉我们解决问题的步骤方法。故选项 C正确。 4.细节题。根据短文第一段可知选项B、C、D都正确，选项A表述不正确，应是People do not analyze every problem they meet。故选A。 5.推断题。根据短文倒数第二段中“Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels.”可知有时候人会想出办法是因为他发现了新东西或是以新的方式去看待事物。而在Sam的例子中，Sam看到了车轮上的口香糖，即发现了新东西，从而解决了问题。故选项A正确。
