The scientists make experiments on mice to find out whether gut bacterium can help to lose weight. They fisrt examined that the mice injected by the lean cell became slim while the other injected by the obese cell gained weight. So the result is that the gut bacterium does affect the figure of mice. Then they wondered if cage-mate can be a factor to influence figures, but unfortunately, it does not have an impact on the figure.

This article solves an problem about the relationship between diet and weight. The author uses a experiment to examine this. When the mice have foods with lower calories than they does normally, they will maintain their former weight, while they absorb a more fried diets,they become fat than before, a phenomenon suggests that we should eat right ingredient to keep figure and that the interatcion between our boby metabolism system and style of diet.

The fist paragragh states that geophysicists has discovered the biggest volcano.
The second paragragh claims the magma of volcano.
The third paragragh illstrates why it is called the "T".
Finally it tells us T is one of three large mountains.

The aritcle is about whether T volcano is formed by lava. At fist the hypothesis made by scientists is wrong because they made a experiment by observing how a seismic wave can affect volcano. The result showed that the rock and stones fall down from the cetral core rather than other places. Then a scientist said lava may come from bottom of volcano and there are many possibilities we still need to explore for sure.

This aritcle states an improvement in medical process that can be applied into real opperations. The scientists finally can distinguish tumor cells and health tissues in surgery by a R specteoscopy so that ancients will be safe. In the experiments, different substances represented different colors like green or blue,and this help doctors to operate easily. Furthermore, this devise is examined by a mice experiment.

讲了智能玻璃。能够智能地调节光和吸收能量,比较环保。有三种模式,透明,半透明,和IR。在此之前讲材料使用有缺陷,电极和所需真空空间方面的,因而这三种模式不能很好地运行。后来改进之后能够顺畅使用。又说这种玻璃现在不能大规模生产,成本很高,商用和私用都用不起,比一般的玻璃贵太多,而且需要的空间很大(?)。要是未来能够降低这种价格,还是有可能推广的。但也有人持反对意见,这种玻璃的功用其实不太需要。但总体来说作者对智能玻璃持积极态度,认为未来随着价格的亲民能大范围推广。
越障实在是感觉写中文要条理地多。前面那几篇都是看完第一遍不回视写的。单词好多不认识,感觉写的怪怪的。还是回去仔细看看都说了些啥。。。
