Additionally, Thomas said motivation plays a big part in a person's grades A student with mastery-oriented motivation approaches a class with curiosity and an interest in the subject, whereas a student with performance-orientated motivation does so solely from a grade standpoint If people spent the same amount of time working ensure they retain important information as they did pulling all-nighters to cram for finals, they could become be more intelligent Students should focus on developing their critical thinking and problem-solving skills rather than simply memorizing information for a test A transcript only shows a student's motivation, dedication and work ethic - not their personality, humor, work or life experiences While grades still matter, we need to stop weighing our intelligence through grades and instead recognize that intelligence comes in all forms (Source: https://www.statepress.com/) 44 Which of the following can be inferred from the passage? A The biggest misconception about marks and intelligence is that they are equivalent to each other B The relevance of intelligence for school grades has changed over time C Intelligence is considered as the strongest predictor of scholastic achievement D Falling grades can be a result of laziness rather than academic capability 45 Which best serves as the title for the passage? A Standardised tests are superficial and unnecessary B Grades don't correlate with a student's intelligence C An attempt to test high grader's intelligence D The close relationship between marks and IQ 46 The word "ethic" in paragraph can be replaced by _ A conduct B honor C law D criteria 47 According to paragraph 2, what is NOT stated about the various theories on intelligence? A Many theories suggest that human intellect is a dynamic and changing variable B One theory concludes that intelligence is a constant throughout one's life C Students' present state can override their intellect as emotions have tendency to take over reasoning D There are many distinctive views concerning the nature of intelligence 48 Which of the following statements is TRUE, according to the passage? A David Thomas believed that enthusiasm claims a marginal position in performance B What we obtain and retain holds more value than the final results C Courses at different levels of rigor and depth can challenge every student individually D Proficiency-inclined students display less curiosity in the subjects than grade-inclined ones 49 According to paragraph 3, why does the author tell the story of Bill Gates dropping out of college? A To imply that a Harvard's drop-out is not the same as a normal or local university's drop-out B To testify the brilliance and innovation of Microsoft's co-founder against the hardship C To illustrate that grades and certificates does not always translate into a person's future potential D To encourage graduates to work and experience life first before going to college 50 The word "them" in paragraph refers to _ A grades B skills C situations D theories ĐỀ THI THỬ TỐT NGHIỆP THPT 2023 KÌ THI TỐT NGHIỆP TRUNG HỌC PHỔ THÔNG NĂM 2023 Bài thi: NGOẠI NGỮ; Môn thi: TIẾNG ANH SỞ GIÁO DỤC VÀ ĐÀO TẠO THÁI BÌNH Mơn thi: TIẾNG ANH (Đề thi có 04 trang) Thời gian làm bài: 60 phút, khơng kể thời gian phát đề HƯỚNG DẪN GIẢI CHI TIẾT Mark the letter A, B, C, or D to indicate the word whose underlined part differs from the other three in pronunciation in each of the following questions A breath B there C though D these Giải thích: A breath /breθ/ (n): thở B there /ðeər/ (n): chỗ đó, nơi C though /ðəʊ/ (conj): dù, D these /ðiːz/ (pron): (dạng số nhiều this) Đáp án A phần gạch chân phát âm /θ/, đáp án lại phát âm /ð/ → Chọn đáp án A A arrive B include C mankind D online Giải thích: A arrive /əˈraɪv/ (v): đến B include /ɪnˈkluːd/ (v): bao gồm C mankind /mỉnˈkaɪnd/ (n): lồi người D online /ˈɒnlaɪn/ (adj): trực tuyến Đáp án B phần gạch chân phát âm /ɪ/, đáp án lại phát âm /aɪ/ → Chọn đáp án B Mark the letter A, B, C, or D to indicate the word that differs from the other three in the position of the primary stress in each of the following questions A parent B disease Giải thích: A parent /ˈpeərənt/ (n): cha mẹ C weather D paper B disease / dɪˈziːz / (n): dịch bệnh C weather / ˈweðər / (n): thời tiết D paper / ˈpeɪpər / (n): giấy Đáp án B có trọng âm rơi vào âm tiết thứ nhất, đáp án cịn lại có trọng âm rơi vào âm tiết thứ hai → Chọn đáp án B A countryman B stadium C disaster D habitat Giải thích: A countryman / ˈkʌntrimən /(n): đồng hương B stadium / ˈsteɪdiəm /(n): sân vận động C disaster / dɪˈzɑːstər /(n): thảm họa D habitat / ˈhỉbɪtỉt /(n): mơi trường Đáp án C có trọng âm rơi vào âm tiết thứ hai, đáp án cịn lại có trọng âm rơi vào âm tiết thứ → Chọn đáp án C Mark the letter A, B, C or D to indicate the correct answer to each of the following questions Our volunteer club received large _ from the students and their parents A experience B benefits C advantages D donations Giải thích: Kiến thức từ vựng: A experience (n): kinh nghiệm B benefit (n): lợi C advantages (n): lợi thế, lơi ích D donation (n): quyên góp Tạm dịch: Câu lạc tình nguyện chúng tơi nhận qun góp lớn từ học sinh phụ huynh em → Chọn đáp án D Air pollution is getting more and more serious in big cities such as Hanoi and Beijing A the B a C an D x Giải thích: Kiến thức mạo từ: Khơng sử dụng mạo từ nhắc đến thành phố lớn nói chung Tạm dịch: Ơ nhiễm khơng khí ngày nghiêm trọng thành phố lớn Hà Nội Bắc Kinh → Chọn đáp án D She had been depressed all day but she started to _ after she heard that she was promoted A break up B cheer up C take up D turn up Giải thích: Kiến thức cụm động từ: A break up: chia tay B cheer up: vui tươi C take up: bắt đầu làm cách thường xuyên D turn up: đến, xuất Tạm dịch: Cô ủ rũ suốt ngày cô bắt đầu tươi tỉnh sau cô nghe tin cô thăng chức → Chọn đáp án B Donald John Trump is the 45th President of the United States, _?
