1 个最佳选项，选项不再是判断对错，而是挖空的形式，属于细节题。三、概括段落大意和补全句子。概括段落大意，简单来说就是根据段落大意，然后根据每个段落的意思，选择一个符合意思的词语。一般有五个选项，而补全句子需要从六个选项中选择五个选项填入对应句子，将其补全。四、填句补文。一般短文会设置 5 处空白，而短文后会设置 6 个句子选项，要求考生根据短文内容将其分别放回原有位置，以恢复文章原貌。五、填词补文。除了填句补文以外，还有填词补文。这种题型在英语四级和六级的考试中，也是有的，主要对于考生单词词汇量要求比较高。六、完形补文。或许大家对于完形补文比较陌生，但是完形填空大家一定知道，其实完形补文也差不多，需要考生根据空白括号后的单词提示，根据上下文，正确填写单词形式，进而补全文章。七、短文写作。凡是英语考试，必然会要求写英语作文，就像考语文一定要作文一样，作文写作字数一般要求在100 词左右。根据指定的话题完成写作任务。成人自考英语二下方免费学历提升方案介绍： 2018年04月自考07008采购与仓储管理真题试卷 格式：PDF大小：306.54KB 2020年08月自考07008采购与仓储管理真题试卷

我有这些试题及答案专科英语等级考复习软件有什么如今与英语相关的工作岗位都比较吃香，一方面英语专业人才仍是社会稀缺资源 ，另一方面是英语相关的工作岗位薪资待遇好，发展前景也更广阔。因此许多热爱学习英语的考生会选择学习这门专业。自学考试专科英语专业一共需要考试的课程科目有十二科，如果大家每次报考四科并且全部通过的话，是可以在一年半的时间里就能申请毕业的。这是最短的时间，但也是对大家要求最严格的时间，因为需要大家每科的成绩都达到合格线才可以顺利拿到自考英语专科毕业证书。所以无论大家是为了更好找工作，还是为了之后考研等深造的话，都是需要尽快拿到毕业证的。有关如何备考，推荐以下几款英语学习app，助力大家早日通过考试！一、 欧陆词典背单词最棒的词典，词库免费！非常智能的跨平台取词功能以及非常完善的离线词库绝对是两大亮点，除了通常我们常用的词库，这各种专业领域的词库也是一应俱全。很方便知识扩展。自考英语核心词有4400个，词组400个，按照自己的时间分配每天的单词量。个人建议20-30个就可以。另外，背单词还是要运用艾宾浩斯的遗忘曲线来，也就是说今天背20个单词，明天背第二批20个，也要同时先复习第一天的20个单词，相当于第二天就是旧20个+新20个。不要害怕遗忘，也不需要强迫自己一定一次性背完。先背最重要的单词，最常用的，边看边写边背。二 、每日英语听力一款用于提高英语听力的应用软件，用真实语境的例句，来深入了解从而掌握英语的学习语言环境。每日英语听力拥有每天更新的海量听力库，并独家提供智能语音高亮跟随功能。与拥有海量词库的《欧路词典》无缝集成，查词典、背单词轻松搞定。要注意的是，听听力集中注意力非常重要，在做听力题时一定要保证自己的注意力高度集中。有一些同学会奇怪，自己的词汇量不少，基础也不差，为什么还是在练习听力的时候，感觉困难重重。明明知道的单词，却听不出来。对于这种情况的同学，很有可能是因为在背记单词的过程中，没有掌握正确的单词读音，或者忽略了连读，因为有时候两个单词连在一起读的时候，会省略th的发音，或者是其他清辅音的发音。建议在练习中用下面这几种方法解决：重新复习音标，修正自己单词发音，并且大声朗读这些单词注意重读音节部分进行听力材料跟读，提高自己的语感和读音的准确性注意连读部分，进行归纳总结三、希赛自考题库自考英语刷题工具，这个app有含历年真题、模拟考卷、章节练成人自考本科学位英语题型？【免费定制个人学历提升方案和复习资料：tg/?bdlk

They can actually be quite lazy! Greyhounds are good at fast races but not long-distance running. They do need regular exercise but they like to run for a short burst and then get back on the bed or a comfortable seat. Another misunderstanding is that greyhounds must be aggressive(好斗的) because they are big in size. In fact greyhounds love people and are gentle with children. Greyhounds can live for 12 – 14 years but usually only race for two or three years, and after that they make great pets. They don’t need a lot of space, don’t make a lot of noise, and don’t eat a lot for their size. Normally, greyhounds can be as tall as 90 cm. There is, however, a small-sized greyhound, which stands only 33cm. Greyhounds come in a variety of colors. Grey and yellowish-brown are the most common. Others include black, white, blue, red and brown or a mix of these. Greyhounds have smooth body coats, low body fat and are very healthy. Because they’re slim (苗条的) they don’t have the leg problems like other dogs the same height. But they do feel the cold, especially since they would much rather be at home in bed than walking around outside.56. The text is written mainly______.A. to tell people how to raise greyhoundsB. to let people know more about greyhoundsC. to explain why greyhounds are aggressiveD. to describe greyhounds of different colors57. It can be inferred that greyhounds_______.A. love big doghousesB. like staying in bed all dayC. make the best guard dogsD. need some exercise outdoors58. Why does the author say that greyhounds make great pets?A. They are big in size.B. They live a very long life.C. They can run races for some time.D. They are quiet and easy to look after.59. If you keep a pet greyhound, it is important________.A. to keep it slimB. to keep it warmC. to take special care of its legsD. to take it to animal doctors regularlyB Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents' home in Missouri for Christmas. I stopped at a gas station(加油站)about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register(收款台), I said hello to an older couple who were also paying for gas. I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend's We chatted on the way into the city, and when I got out of the car, the husband gave me his business card. I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful. Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I'd left the lights on all day, and the battery(电池)was dead. Then I noticed that the Friendly Ford dealership - a shop selling cars - was right next door. I walked over and found two salesmen in the showroom. "Just how friendly is Friendly Ford?" I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said. "Thank you" - two powerful words. They're easy to say and mean so much.60. The author planned to stop at Oklahoma City_________.A. to visit a friendB. to see his parentsC. to pay at the cash registerD. to have more gas for his car61. The words “took off” underlined in Paragraph 2 mean “______”.A. turned offB. moved offC. put upD. set up62. What happened when the author found smoke coming out of his car?A. He had it pulled back to the gas station.B. The couple sent him a business card.C. The couple offered to help him.D. He called his friend for help.63. The battery of the author’s car was dead because_______.A. something went wrong with the lightsB. the meeting lasted a whole dayC. he forgot to turn off the lightsD. he drove too long a distance64. By telling his own experiences, the author tries to show______.A. how to write a thank-you letterB. how to deal with car problemsC. the kind-heartedness of older peopleD. the importance of expressing thanksC A study of English learning problems was carried out among a total of 106 foreign students. It shows that most students considered understanding spoken English to be their biggest problem on arrival. This was followed by speaking. Writing increased as a problem as students discovered difficulties in writing papers that they were now expected to hand in. Reading remained as a significant(显著的) problem. The information gained helped us in determining where special attention should be paid in our course. Although many students have chosen to join the course with a reasonable motivation(动机), we considered it important to note what seemed to encourage interest. Nearly all the students have experienced some kind of grammar-based English teaching in their own country. To use the same method would be self-defeating because it might reduce motivation, especially if it has failed in the past. Therefore a different method may help because it is different. Variety of activity was also seen as a way of maintaining(保持) or increasing motivation. Several years ago we had one timetable that operated throughout, but we soon found that both the students and the teachers lost interest by about halfway through the ten weeks. This led us to a major re-think, so finally we brought it into line with the expressed language needs of the students.65. What is the text mainly about?A. Foreign students have more problems.B. There are many ways to improve English.C. Teaching should meet students’ needs.D. English learning problems should be studied again.66. Writing became a bigger problem when foreign students________.A. had to write their papersB. became better at speakingC. became less interested in readingD. had fewer problems with listening67. We may infer from the last two paragraphs that ________.A. different teaching methods should be usedB. grammar-based teaching seems to be encouragingC. English courses are necessary for foreign studentsD. teaching content should be changed halfway.D Since my retirement(退休) from teaching music in 2001, I have spent a good deal of time painting as an artist. I actually began drawing again in the summer of 1995 when my father died, so perhaps I was trying to recover from the loss of my father, or maybe it was just that it brought back memories of him. In any case, I drew pen and ink animals and landscapes(风景画) much influenced(影响) by Krenkel and St. John for five years. For some strange reason, I had been waiting until my retirement to start doing watercolors again, but as soon as I walked out of the school door for the last time I picked up my brushes and rediscovered Andrew Wyeth, who quickly became my favorite artist. I had looked through all the art books I had on my shelves and found his watercolors to be the closest to how I thought good watercolors should look. So I painted landscapes around Minnesota for three years and tried out many other types of painting. However, watercolors remained my first choice, and I think I did my best work there, showing my paintings at a number of art exhibitions. Art is now together with my piano playing and reading. There is a time for everything in my world, and it is wonderful to have some time doing what I want to do. As Confucious once said, “At seventy I can follow my heart’s desire.”69. What is the text mainly about?A. Learning to paint in later life. B. How to paint watercolorsC. An artist-turned teacher D. Life after retirement70. The author started drawing again in 1995 because_________.A. he hoped to draw a picture of his fatherB. he couldn’t stop missing his fatherC. he had more time after retirementD. he liked animals and landscapes71. We can infer from the text that the author__________.A. had been taught by Krenkel and St. JohnB. painted landscapes in Minnesota for 5 yearsC. believed Wyeth to be the best in watercolorsD. started his retirement life at the age of severty72. How does the author probably feel about his life as an artist?A. Very enjoyable. B. A bit regretful C. Rather busy. D. Fairly dull.EPhillip Island Penguins(企鹅) The Little Penguin has called Phillip Island home for untold generations.
