赞同:学校的science class要求观察—create
Watching tv too much没时间与父母交流—language+thoughts
不赞同:与别的小朋友无谈资,心理受挫
Although science and technology is advancing, the range of entertainment after school for children is more limited today than it was a few decades ago. Children now prefer to stay at home watching television or playing video games all time after school rather than to go outside and play around. Parents, as the first educators of their children, are also very anxious about this phenomenon. For the sake of children's performance in school, parents think that the time children spend on watching TV should be limited.
Watching TV for too much time distracts children's attention from the nature world. In the development of children's learning ability, cultivation of their curiosity and creative thinking is very important. Children can obtain them by playing intelligence toys such as Lego Bricks and puzzles, or by observing the habits of animals and insects in the nature. While spending a lot of time watching TV at home closes the door of the amazing outside world to children. They are also inclined to be addictive to watching TV. As a result, they will lack the ability to observe and analyse phenomenon, which is crucial to the science class at school.
Moreover, more time children consume on watching TV, less time they have to communicate with their friends and parents. Scientific research showed that children usually spend more time watching TV have a higher 30% tendency to have communication disorders than those who spend less. During watching TV, children just passively accept the information that television conveys, they barely think the accuracy of the information, let alone to communicate their thoughts with their friends or parents. This will lead to degradation in their expressing ability, and miss the best time to practise their language and communicating skills, which are very essential in their classes at school.
However, not watching TV at all also leads to potential problems in children's psychological development. Children tend to discuss fancy persons, fashionable cloths, or popular cartoons and songs they watched on TV. If your child knows nothing about his classmates' favourite topics, he will be squeeze out of the peer group and suffer loneliness, which will have a very serious effect on the development of children's fragile psychology.
In conclusion, I think that the time children spend on watching TV should be limited by their parents. In order to perform well at school, parents should encourage their children to explore more in the nature world and spend more time communicating with them instead of letting them sit in front of the television all day long.

The lecture completely refutes the passage. It is said in the lecture that the cause of the decline of some sea otter population off the Alaskan coast is more likely to be predation, contrary to the cause stated in the passage, which is pollution hypothesis. The professor says that no one finds exact evidence of pollution along the coast. In addition, if pollution hypothesis is the main cause, its effect on sea otters should be consistent with other coastal inhabitants. The lecture also refutes the fact that orcas eat larger prey by stating that they have to eat smaller preys including sea otters, seals and sea lions because larger preys disappeared due to human hunting. Finally, the professor believes that predation could also explain the uneven pattern of otter decline. At locations accessible to orcas, the sea otter population drops, while at shallow and rocky locations which are inaccessible to orcas, the population remains stable.
