例如:My favourite sport is football. I was member of our school football team. isNow my picture and prize is hanging in the library. are上述两例分别属于时态错误和主、谓不一致错误。

二、名词数指名词单、复数形式的用法错误。
常表现为将名词复数写成单数。
例如:…so that I’ll get good marks in all my subject. subjects三、区分形和副即区分形容词和副词在句子中的作用和具体用法。

Now, the American Medical Association (AMA) has a new set of guidelinesaimed at protecting players from the danger of concussions—serious injuries caused by a blow to the head.“By raising awareness of the serious risks associated with concussions and ensuring that the appropriate guidelines are in place, we can reduce the number of young athletes who may return to the game too soon, which can put their health at further risk,〞 said AMA Board Member Jack Resneck Jr., M.D., in a statement.The policy recommends that young athletes who may have a concussion be taken off the field as soon as possible. Then, they are only to return to their sport with a doctor's written approval. The policy also sets agespecific rules for hea lth care professionals and athletic organizations in evaluating and caring for concussions.According to the Center for Disease Control and Prevention (CDC), a concussion is a type of traumatic (创伤) brain injury caused by a bump, blow, or jolt to the head or hit to the body that causes the head and brain to move rapidly back and forth. This type of movement can cause the brain to bounce around or twist inside the skull (颅骨). It can damage brain cells and create chemical changes in the brain.The CDC says that between 1.6 million and 3.8 million traumatic brain injuries caused by sports and recreationrelated activities occur in the U.S. every year.A study from the Center for Injury Research and Policy showed that as many as 40% of high school athletes return to playing before they should. The AMA's new guidelines should help to bring those numbers down.1.Why does the AMA set the new guidelines?A.To raise safety standards of sports. B.To protect athletes from concussions.C.To set rules for health care evaluation. D.To help players return to the game quickly.2.What should young athletes who may have a concussion do?A.Avoid using the head. B.Leave the field forever.C.Get treatment in time. D.Switch to another sport.3.What is paragraph 4 mainly about?A.What a concussion is. B.What causes damage to brain cells.C.How the CDC works. D.How a concussion can be prevented.4.Which of the following is the best title for the text?A.Rules for Safer Play B.Sports Injuries in the USC.Advice to Athletes D.New Policies for DoctorsBwatch live footage from the frozen heights of Everest. But communicating with a submarine (潜艇) or a diver is not so easy. The lack of practical methods for sharing data between underwater and airborne devices has long been a frustration for scientists. The difficulty stems from the fact that radio signals work perfectly in air travel but poorly in water. Sonar (声呐) signals used by underwater sensors reflect off the surface of the water rather than reaching the air.Now, researchers at MIT have developed a method with the potential to revolutionize underwater communication. “What we've shown is that it's actually feasible to communicate from underwater to the air,〞 says Fadel Adib, a professor at the MIT Media Lab, who led the research.The MIT researchers designed a system that uses an underwater machine to send sonar signals to the surface, making vibrations (震动) correspond to the data. A surface receiver then reads and decodes these tiny vibrations. The researchers call the system TARF. It has any number of potential realworld uses, Adib says. It could be used to find downed planes underwater by reading signals from sonar devices in a plane's black box and it could allow submarines to communicate with the surface.Right now the technology is lowresolution. The initial study was conducted in the MIT's swimming pool at maximum depths of around 11 or 12 feet. The next steps for the researchers are to see if TARF is workable at much greater depths and under varying conditions—high waves, storms and schools of fish. They also want to see if they can make the technology work in the other direction—air to water.If the technology proves successful in realworld conditions, expect “texting while diving〞 to be the latest underwater fashion.5.What does the author mainly talk about in Paragraph 1?A.The future of video chat underwater and in the air.B.The difficulty of communication from underwater to the air.C.The frustrations of developing underwater devices.D.The current situation of communicating with a submarine.6.What does the underlined word “feasible〞 mean in Paragraph 2?A.Changeable. B.Convenient. C.Achievable. D.Alternative.7.What do we know about TARF?A.It is widely used to find downed planes.B.It can work well at great depths underwater.C.It is an underwater machine that sends signals.D.It can send, receive and read signals from underwater.8.What is the best title for the text?A.The Realworld Uses of Sonar TechnologyB.A Breakthrough in the Application of Video ChatC.Full Watertoair Communication Is Closer to RealityD.TARF Is Becoming a New Means of CommunicationⅢ.书面表达[2020·1月浙江卷]假定你是李华,你校将举办外国学生中文演讲比赛,请给你的英国朋友George写封邮件邀请他参加。

科学研究证实,虽然大脑的重量只占人体重量的2%-3%,但大脑消耗的能量却占食物所产生的总能量的20%,它的能量来源靠葡萄糖氧化过程产生。
据医学文献记载,一个健康的青少年学生30分钟用脑,血糖浓度在120毫克/100毫升,大脑反应快,记忆力强;90分钟用脑,血糖浓度降至80毫克/100毫升,大脑功能尚正常;连续120分钟用脑,血糖浓度降至60毫克/100毫升,大脑反应迟钝,思维能力较差。
我们中考、高考每一科考试时间都在2小时或2小时以上且用脑强度大,这样可引起低血糖并造成大脑疲劳,从而影响大脑的正常发挥,对考试成绩产生重大影响。
因此建议考生,在用脑60分钟时,开始补饮25%浓度的葡萄糖水100毫升左右,为一个高效果的考试加油。
二、考场记忆“短路”怎么办呢?对于考生来说,掌握有效的应试技巧比再做题突击更为有效。
1.草稿纸也要逐题顺序写草稿要整洁,草稿纸使用要便于检查。
不要在一大张纸上乱写乱画,东写一些,西写一些。
打草稿也要像解题一样,一题一题顺着序号往下写。
最好在草稿纸题号前注上符号,以确定检查侧重点。
为了便于做完试卷后的复查,草稿纸一般可以折成4-8块的小方格,标注题号以便核查,保留清晰的分析和计算过程。
2.答题要按先易后难顺序不要考虑考试难度与结果,可以先用5分钟熟悉试卷,合理安排考试进度,先易后难,先熟后生,排除干扰。
考试中很可能遇到一些没有见过或复习过的难题,不要蒙了。
一般中考试卷的题型难度分布基本上是从易到难排列的,或者交替排列。
3.遇到容易试题不能浮躁遇到容易题,审题要细致。
圈点关键字词,边审题边画草图,明确解题思路。
有些考生一旦遇到容易的题目,便觉得心应手、兴奋异常,往往情绪激动,甚至得意忘形。
要避免急于求成、粗枝大叶,防止受熟题答案与解题过程的定式思维影响,避免漏题,错题,丢掉不该丢的分。
4. 答题不要犹豫不决选择题做出选择时要慎重,要关注题干中的否定用词,对比筛选四个选项的差异和联系,特别注意保留计算型选择题的解答过程。
当试题出现几种疑惑不决的答案时,考生一定要有主见,有自信心,即使不能确定答案,也不能长时间犹豫,浪费时间,最终也应把认为正确程度最高的答案写到试卷上,不要在答案处留白或开天窗。
5.试卷检查要细心有序应答要准确。
一般答题时,语言表达要尽量简明扼要,填涂答题纸绝不能错位。
答完试题,如果时间允许,一般都要进行试卷答题的复查。
复查要谨慎,可以利用逆向思维,反向推理论证,联系生活实际,评估结果的合理性,选择特殊取值,多次归纳总结。
另外,对不同题型可采用不同的检查方法。
选择题可采用例证法,举出一两例来能分别证明其他选项不对便可安心。
对填空题,则一要检查审题;二要检查思路是否完整;三要检查数据代入是否正确;四要检查计算过程;五要看答案是否合题意;六要检查步骤是否齐全,符号是否规范。
还要复查一些客观题的答案有无遗漏,答案错位填涂,并复核你心存疑虑的项目。
若没有充分的理由,一般不要改变你依据第一感觉做出的选择。
6、万一记忆短路可慢呼吸考试中,有些考生因为怯场,导致无法集中精神,甚至大脑忽然一片空白,发生记忆堵塞。
此时不要紧张,不妨尝试如下方式:首先是稳定心态,保持镇静,并注意调节自己的呼吸率。
先慢吸气,当对自己说放松时缓慢呼气,再考虑你正在努力回忆的问题,如果你仍不能回想起来,就暂时搁下这道题,开始选做其他会的试题,过段时间再回过头来做这道题。
第二,积极联想。
你不妨回忆老师在讲课时的情景或自己的复习笔记,并努力回忆与发生记忆堵塞问题有关的论据和概念,把回忆起的内容迅速记下来,然后,看能否从中挑出一些有用的材料或线索。
