问题     Lipstick (口红) plays an important role in attraction and can even protect the lips from drying out in harsh weather. No wonder it’s the most important thing in a woman’s cosmetics (化妆品) bag.
   Colouring the lips is certainly not a new idea. It was practiced as early as 3500 BC.
   In the past, a natural dye was used to paint lips. It was not until the 17th century that lipstick manufacturing really took off. The lipstick was made of mixtures that included pig fat and red sandalwood(檀香油). It was kept in tiny pots and applied with a colouring stick.
   Lipstick was invented and first presented by Parisian perfumeries (香水制造商) in Amsterdam. But these "little red sausages" were less practical. They were wrapped in silk paper and the ends had to be broken off before each use. They also did not come cheap.
   Over the years the sticks became less expensive and new colours were developed. But it was not until 1950 that lipstick accidentally was reinvented — this time by the Americans.
   Today there are so many types of lipsticks and shades that it is hard to keep track of them. Faced with many choices in the cosmetic departments, it is easy to forget that there is a whole science to manufacture them.
   The basic materials are colours, oils and waxes. But they can contain up to 30 different materials. Lipstick manufacturers have to achieve a careful balance. "You need a thicker oil to make the lipstick last longer, but a thinner one to make it easy to apply," says Cornelia Riede, product developer at Nivea Beaute in Hamburg.
   Different oils also provide protection for lips, preventing them from drying up.
   The waxes used in lipsticks must strike the right balance between strength and elasticity(弹性). And up to nine different colouring matters could be needed to find the right shade.
   No one today need fear dangerous materials in lipsticks. A study by a leading German consumer organization found dangerous materials such as lead or cadmium(镉) are hardly a problem any more — even in the cheapest products.
   Today, the question is whether to choose a conventional lipstick or the newest, long-lasting variety.
The underlined phrase "keep track of" in this passage means ______.
选项 A、find
B、follow
C、use
D、store
答案B
解析 词义推测题。该词所在句的意思是：如今有这么多种口红和颜色，因此很难——它们。而由后面一句的意思(面对化妆品店里如此多的选择，人们……)及该词所在句本身的搭配关系与常识可知，keep track of在此应当是指“跟上”口红的式样，所以答案为[B]。
