3．Different people may find that different learning methods work best for them．While some would turn to tutoring in order to get better grades，others choose to join study groups．In fact，many universities encourage their students to form study groups and make good use of them．
"Two heads are better than one．"That's the simple idea behind study groups．By participating in a study group，students can benefit from some of their best academic resources：other students．They get to pick each other's brains and improve their own understanding of different problems．Moreover，study groups can create the slightly tense atmosphere in which it's good to study．For example，some students tend to procrastinate （拖延） when they are studying by themselves； however，by joining a study group，they get to observe their peers who are working diligently and are likely to thus have motivation for working harder．
Study groups work best when they are small，but not too small-four to five participants is about right．And it's necessary to make sure everyone has the same goal，to prepare for a particular test，to discuss class readings or to review the week's lecture notes．Besides，socializing in the group would make studying more fun as long as it took up only a small portion of group study time．
In addition，to maximize the efficiency，some study groups like to assign members certain roles，and thus efficiency will be promoted．Besides an organizer，who gets group members to agree to a common purpose and a convenient time and place，there often is a group member playing the role of a source-seeker，whose duty is to remind group members to identify their sources．For instance，when a group member says"I read somewhere that…，"the source-seeker should ask for specifics．This person reminds the group that it's important to know who said what and where it was said．And a gatekeeper，who tries to make sure that all group members are participating，may ask a direct question to help a shy person participate，or find a way to get a dominating member to listen．
（Note：Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS．）

78．Many universities encourage students to take advantage ofstudy groups/learning in groups for better grades rather than learning alone．
79．Peers are not only the best academic resources but also motivate each other towork harder/work hard/work diligently when learning in groups．
80．According to paragraph 3，besides the small size，what are the other two factors that could help a study group work bestThe same goal and not-too-long socializing．（not-long-timesocializing）？
81．All the members in the study group will be assigned different roles because people believe that it will result inpromoting the efficiency/maximizing the efficiency．．

10．For people with thousands of pages to read，speed reading seems like a manna （甘露） from heaven．In addition，speed reading helps lighten the load of information you have to absorb since it provides a filter that you can use in screening all bits of information before you approach them．
（71）FExamining how much information you need will help you identify how you should read a certain document to maximize your learning and comprehension．Thorough reading may no longer be necessary in some cases，such as when you only need an outline of a certain document．
Another skill that can ease the burden of a reader is the ability to read words in blocks．Make sure you do not spend too long on a certain block．（72）BThis will also make reading less tiresome and boring．
To master this important skill，you have to practice reading more and more words in a certain block at one time．A suggestion shared by some experts regarding this step is to increase the distance between you and the document you are reading．If you can read more and more words in one block，you can cut down on the time it usually takes you to read a certain text and you will be able to read more in a shorter period．
Readers should also practice reducing the number of times they go back to previous sections or blocks．Using a pointer such as the tip of a pencil or pen can also help to make the flow of your reading smoother and faster．（73）AThus，your speed in reading will largely depend on the speed of the movement of your pointer．
If you still find yourself confused about the topic even after you have finished reading the document，do not re-read right away．Re-reading immediately will just lead to slower speed in reading．（74）CGetting your own reading corner will also help．
（75）DContinue practicing and practicing the techniques aforementioned and soon，you'll achieve the reading speed that will work best for you．

A．In this technique，your eyes will follow the tip of the pointer．
B．This saves time and reduces the effort that you have to make．
C．Taking a short break first is recommended before reading the material again．
D．As a final note，the most important point is consistent and deliberate practice．
E．Your invaluable time can be saved if you can have your reading speed doubled．
F．The first step to increase your reading speed is to identify the specific information you need．
G．Reducing the time you spend on a specific number of words in a block will make no difference．
