单选题Doctors are starting to find more and more information that suggests a connection between exercise and brain development. According to some research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developeD． The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. Margaret Barnes, a pediatrician, believes in the importance of exercise. (82)She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. In studies with seniors, research has shown that exercise helps older people as well. The exercise doesn't have to be very difficult. The main goal is just to increase the heart rate. And especially when learning new movements, such as yoga or tai chi, it appears that new memory paths open up in the brain. This can improve people's short-term memory.

单选题Passage One One of the most interesting experiments in electronic communication I've ever seen is coming from Wave. It's real-time e-mail. What that means is that as you're typing a message in Wave, either a new message or a reply, the person you're writing to can see what you're typing as you type it. Sounds awful, right? You don't have to use Wave in this real-time way. It also works as a standard e-mail. What's really different about Wave is that if you're replying to a message and the person you're replying to happen to be online, they can jump into the conversation at that point, and change what is an e-mail conversation into an instant message conversation or a chat. Wave right now is still closed to most users. And Wave isn't yet connected to other communication systems, like regular e-mail, which means that the only people we can Wave with are other people on Wave as well. So we don't yet know what using Wave will be like once it gets crowded like e-mail. Also, the technology behind Wave is far more demanding on servers and the Internet itself than regular e-mail or chat, so we don't know if the technology will work at scale. But Wave really is a current re-think of e-mail. A lot of people won't like it. A lot of people didn't like e-mail either when it first showed up. But people will find real uses for Wave or whatever it becomes, and it's one of the most interesting new takes on communication. Even if you don't like it, it will make you think differently about e-mail.
