But Ghirardi and her colleagues have discovered that by removing a chemical called sulfate from the environment that the algae grow in, they will make hydrogen instead of sugars, even when air is present. 藻類在空氣中雖然可以工作，但是充滿困難。 The researchers hope that algae will one day be an easytouse fuel source. The anisms are cheap to get and to feed, Ghirardi says, and they can grow almost anywhere: You can grow them in a reactor, in a pond. You can grow them in the ocean.

Then the researchers turned to the teachers:To find out which teachers were anxious about math,the researchers asked the teachers how they felt at times when they came across math
