1、课时作业4Earthquakes.阅读理解AResearch into how breathing affects the brain has become an evermore popular field in recent years. New methodology (方法论) has enabled more studies, many of which have concentrated on the memory.“Our study shows that we remember smells better if we breathe through the nose. The

2、process takes place between learning and memory recovery，” says Dr Arshamian, a researcher from the Karolinska Institute. This is the first time someone has demonstrated this point of view.This phenomenon (现象) has not previously been available for study since the most common laboratory animals were

3、rats and mice which cannot breathe naturally through their mouths. For Dr Arshamians study, researchers split the participants into two groups. Both groups were given the same period of time to learn a set of 12 different smells. Then, one group was asked to breathe through noses and the other group

4、 through mouths for one hour. When the time was up, the two groups were presented with the old as well as a new set of 12 smells. And then, researchers asked them to tell if each smell was from the old set or the new one. The results showed the group that breathed through noses strengthened their me

5、mories better.Earlier research has shown that different parts of the brain are affected in different phases of breathing. But how breathing is related to brain activity and then how the brain affects our behavior are still unknown. According to Dr Arshamian, brain measurement in this direction has b

6、een a practical impossibility for years as electrodes (电极) had to be inserted directly into the brain. “The idea that breathing affects our behavior is actually not new，” adds Dr Arshamian. But no one has managed to prove scientifically what actually goes on in the brain during breathing. Dr Arshami

7、ans team are developing a new means of measuring brain activity without having to insert electrodes, which will potentially open a new chapter in uncovering new clinical knowledge.本文是一篇说明文。文章主要说明了用鼻子呼吸有助于巩固记忆。1What did Dr Arshamians study probably focus on?AThe link between breathing and memory.BThe

8、 improvement on smell recognition.CThe new approach of promoting memory.DThe process of learning and memory recovery.答案：A解析：推理判断题。根据第一段中的Research into how breathing.concentrated on the memory和第二段中的Our study shows that we remember.says Dr Arshamian可知，Dr Arshamian研究的焦点很可能是“呼吸和记忆之间的联系”。2Why did the pre

13、cades its precise location (位置) was unknown. Researchers with the Monterey Bay Aquarium Research Institute (MBARI) spotted a strange shape in that area in 2008.

14、red to be a shipwreck (失事船只). It measured 197 feet long and rested nearly 2,300 feet below the surface.Even then, the identity of the shipwreck was uncertain. Yet another MBARI team revisited the location to do further exploration. They sent remotely operated vehicles (ROVs) and took photos of the d

15、amaged ship. Though it was covered with deepsea sponges and other animals, the scientists were able to spot letters spelling out its name, confirming that the shipwreck was American Heritage.As one of the MBARI scientists who found American Heritage, chief ROV pilot Knute Brekke had previously worke

16、d on the ship. And he was on duty with the diving company American Pacific Marinethe owner of American Heritagethe night the ship began taking on water and eventually sank.MBARI spokesperson Kim FultonBennett said to Live Science about the discovery, “The model is not complete, as floating ropes and

17、 poor visibility kept the pilots from getting too close to the wreck. Nevertheless, the 3D reconstruction is detailed enough to show that American Heritage is now home to potentially thousands of sponges. Shipwrecksaccidental and intentionaloften transform into the shelter for diverse communities of

18、 ocean life.”本文是一篇说明文。主要介绍了科学家发现了一艘名为American Heritage的沉船并用3D数字模型复原了这艘船。4What is the main idea of the text?AA valuable treasure was discovered.BSpecial sponges were found under sea.C3D model reconstructed a sunken ship.DA sunken ship was gotten out of water.答案：C解析：主旨大意题。根据第一段以及全文内容可知，本文主要介绍了科学家发现了一艘
