A letter of application is a sales letter in which you are both salesperson and product, for the purpose of an application is to attract an employer's attention and persuade him or her to grant you an interview. To do this, the letter presents what you can offer the employer, rather than what you want from the job. Like a r\u00e9sum\u00e9, the letter of application is a sample of your work and an opportunity to demonstrate your skills and personality. If it is written with flair and understanding and prepared with professional care, 202 \/ 407","it is likely to be very effective. While the r\u00e9sum\u00e9 must be factual, objective, and brief, the letter is your chance to interpret and expand. It should state explicitly how your background relates to the specific job, and it should emphasise your strongest and most relevant characteristics. The letter should demonstrate that you know both yourself and the company. The letter of application must communicate your ambition and enthusiasm. Yet it must be modest. It should be neither aggressive nor compliant: neither pat yourself on the back nor ask for sympathy. It should never express dissatisfaction with the present or former job or employer. And you should avoid discussing your reasons for leaving your last job. Finally, it is best that you not br oach the subject on salary. Indeed, even if a job advertisement requires that you mention your salary requirements, it is advisable simply to call them \\\"negotiable.\\\" However, when you go on an interview, you should be prepared to mention a salary range. For this reason, you should investigate both your field and, if possible, the particular company. You don't want to ask for less than you deserve or more than is reasonable. (Adapted from \\\"Select Readings - Intermediate\\\" by Linda Lee and Erik Gundersen) Choose an option (A, B, C or D) that best answers each question. 36. What is the passage mainly about? A. Advice on how to find a good job B. Things to avoid during a job interview C. Tips for writing an effective letter of application D.

A. persuade the employer to grant him\/her an interview B. get further information about the company C. advertise a product to attract more customers D. present what he\/she wants from the job 38. The word \\\"it \\\" in paragraph 2 refers to _. A. the letter of application B. an opportunity C. your work D. the r\u00e9sum\u00e9 39. According to the passage, what can be inferred about a letter of application? A. It should express the applicant's dissatisfaction with his\/her former employer. B. It should refer to the applicant's reasons for leaving his\/her previous job. C. It should be written very briefly, but in a formal style. D.

African swine fever is one of the most dangerous diseases of swine. Since its first identification in East Africa in the early 1900s, African swine fever (ASF) spread to Kenya in the 1920s; transcontinental outbreaks in Europe and South America in the 1960s and in Georgia (Caucasus) in 2007 led to subsequent transmission to neighboring countries east of Georgia. Along with the outbreaks in the eastern territory of the Russian Federation, acute ASF outbreaks were reported in China in 2018. 2. During January 15\u201331, 2019, a disease outbreak at a family-owned backyard pig farm in Hung Yen Province, Vietnam, was reported. The farm, about 50 km from Hanoi and 250 km from the China border, housed 20 sows. In the early stage of the outbreak, 1 piglet and 1 sow exhibited marked redness all over the body, conjunctivitis, and hemorrhagic diarrhea. Breeding gilts demonstrated anorexia, cyanosis, and fever (>40.5\u00b0C). 3. Since ASF was first recorded in Vietnam on February 1, 2019, the country has culled more than 85,000 pigs, according to the official reports. However, it has been promptly controlled thanks to the timely response of the Government; Prime Minister Nguyen Xuan Phuc; the Ministry of Agriculture and Rural Development (MARD); and other relevant ministries, agencies, and localities. Since then, a lot of families have quitted pig farming. 4. ASF is a fatal animal disease affecting pigs and wild boars with up to 100 percent mortality, and subsequently damaging trade and causing global economic losses. The ASF virus does not affect humans. The only known preventative measure is a mass cull of infected livestock. The disease spreads by contact between infected pigs or other wild animals and can inflict massive economic damage on farms. Choose an option (A, B, C or D) that best answers each question. 36. What is the passage mainly about? A. A general view of African swine fever and its outbreaks and effects in Vietnam B. How African swine fever was controlled in Vietnam 222 \/ 407","C. Definition and effects of African swine fever D. The ways to identify African swine fever based on symptoms 37. When is a pig identified as infected with African swine fever? A. When Prime Minister Nguyen Xuan Phuc came to a family\u201fs farm in Hung Yen Province, Vietnam. B. When it exhibits marked redness all over the body, conjunctivitis, hemorrhagic diarrhea and fever. C. When the farmer realized it no longer stayed healthy. D. When localities tell farmers that their pig is infected with African swine fever. 38. What does the word it in paragraph 3 refer to? A. the reports B. February 1st C. the disease D. the pig 39. What does the word subsequently in paragraph 4 mean? A. early B. previously C. formerly D. afterward 40. What can be inferred about the food market trends in Vietnam after the African swine fever ends? A. The price of pork will keep falling. B. People will try to buy as much pork as possible. C. There is a high rise in pork\u201fs price due to the scarcity of pigs. D. Human health will weaken because of the remnants of the disease. PH\u1ea6N 2.

It has been practiced for thousands of years under the name of \\\"selective breeding\\\". Animals and plants were chosen because they had traits that humans found useful. Some animals were larger and stronger than others, or they yielded more food, or they had some other trait that humans valued. Therefore, they were bred because of those traits. Individuals with those traits were brought together and allowed to breed in the hope that their offspring would have the same traits in greater measure. Much the same thing was done with plants. To produce bigger or sweeter fruit, or grow more grain per unit of land, strains of plants were combined and recombined to produce hybrids, or crossbreeds that had the desired traits in the right combinations. All the while, however, biologists wondered: is there a more direct and versatile way to change the traits of plants and animals? Could we rewrite, so to speak, the heredity of organisms to make them serve our needs better? In the 20th century, genetic modification made such changes possible at last. Now, it was possible to alter the genetic code without using the slow and uncertain process of selective breeding. It even became possible to blend plants and animals genetically: to insert animal genes into plants, for example, in order to 243 \/ 407","give the plants a certain trait they ordinarily would lack, such as resistance to freezing. The result was a tremendous potential to change the very nature of biology. Choose an option (A, B, C or D) that best answers each question. 36. What is the passage mainly about? A. The arguments against genetic modification B. The benefits brought about by genetic modification C. The reasons behind selective breeding of plants D. The development of genetic modification 37. The word \\\"them\\\" in paragraph 2 refers to . A. organisms B. traits C. animals D. plants 38. The word \\\"blend\\\" in paragraph 3 mostly means . A. combine B. collect C. gather D. carry 39. According to the passage, selective breeding _ . A. is slower and uncertain than genetic modification B. works much better on plants than on animals C. helps change the traits of plants rather than animals D. has a huge potential to change the nature of biology 40. Which of the following IS NOT mentioned as the achievements of genetic modification? A. Giving plants necessary traits taken from animals\u2019 genes B. Producing hybrids or crossbreeds from many animals and plants C. Encouraging people to give up selective breeding completely D. Making big changes to the very nature of biology PH\u1ea6N 2.
