句意：黛比不知道皮特这些天正在想什么。她认为这是他的问题，不是她的。所以她不在乎。
考查动词的时态。is thinking现在进行时；thinks一般现在时的动词三单；thought一般过去时。分析第一处可知，此处表示“黛比不知道皮特这些天正在想什么”，强调正在发生的动作，所以使用现在进行时；第二处描述客观情况，又因为主语是She，所以使用一般现在时的动词三单。故选A。
阅读快车系列答案【题目】 There are purple clothes, purple handbags, purple bicycles, purple furniture, even purple computers! Purple is very popular today. But a long time ago, purple was a very expensive and unusual color. Let’s take a look at the rich history of the color purple.
Some scientists believe that the first plants to appear on Earth over 500 million years ago probably looked purple, not green. Plants today are green because they use green chlorophyll (叶绿素) to produce energy. But these early plants probably used something called retinal, which is a dark purple color.
During the time of the Roman Empire (37 BC-476 AD), it was very difficult to make purple dye (染料). The dye came from sea snail (海螺). But 10,000 dead sea snails got you just one gram of purple dye... as well as a very bad smell! This special purple dye… was called Tyrian purple, and it was the preferred colour of emperors (皇帝).
In 16th-century England, purple was only for the king’s family members. Queen Elizabeth I’s clothes were purple, but common people were not allowed (允许) to wear the color.
In 1856, William Perkin, an 18-year-old science student, noticed something strange while doing an experiment (实验). The chemicals he used to clean his instruments mixed with the chemicals he used in his experiment and produced a bright purple color. This discovery led Perkin to start a company using this chemical mixture to make purple dye. The dye was not expensive. Thanks to Perkin, now anyone can afford to wear purple.
