阅读：中心论点：many skeptics doubt that t the nests found inside the fossilized trees were not created by bees.
分论点1：No fossil remains of actual bees have been found that date to 200 million years ago.
分论点2：Flowering plants were in absence 200 million years ago.
分论点3：The fossilized structures lack some of the finer details of bees’ nests such as the chambers lacking caps.
听力：中心论点：The arguments in the reading are not convincing.
分论点1: Bees couldn’t be preserved as fossils at that time. No trees prodcing resin, bees couldn’t be preserved.
分论点2: Bees existed before flowering plants. Bees feed on non-flowering plants.
分论点3：There’s chemical evidence that supports the theory that bees built the chambers.
cast doubt on, assert, on top of that, in absence, preserve, feed on, precede, adapt to, remain stable, analyze, turn out.
