Đáp án B
Dịch câu đề bài: Chất này rất độc. Quần áo bảo hộ phải luôn được mặc.
A. Không dịch vì sai ngữ pháp. Để nối hai mệnh đề, chỉ cân dùng một liên từ. Đáp án A có hai liên từ là “since” và “so”.
B. Chất này độc đến nỗi mà quần áo bảo hộ phải luôn được mặc. → đúng
C. Không dịch vì sai ngữ pháp. Theo ngữ pháp, “such” + danh từ. Ở đây theo sau “such” chỉ là “toxic” (tính từ) nên C sai.
D. Không dịch vì sai cách dùng cấu trúc. Có tồn tại cấu trúc S + V + Too + adj/adv + to V: quá....nên không thể... Tuy nhiên, nếu dùng cấu trúc này thì “S” cũng là người gây ra hành động “to V”. Ở đáp án này, “S” là “the substance” (chất này) mà “to V” lại là “to wear” (mặc quần áo). Chất thì không thể gây ra hành động mặc quần áo → sai.
Đáp án B đúng vì phù hợp nghĩa. Ở trong đáp án này, cấu trúc đảo ngữ với “so” được sử dụng: So + adj/ adv + trợ động từ + S + V + ... (nếu động từ chính là “be” thì đảo “be” lên trước chủ ngữ).Gói VIP thi online tại VietJack (chỉ 200k/1 năm học), luyện tập gần 1 triệu câu hỏi có đáp án chi tiết

The Americans with Disabilities Act (ADA) was signed into law in 1990. This law extends civil rights protection to persons with disabilities in private sector employment, all public services, and in public accommodations, transportation, and telecommunications. A person with disability is defined as someone with a mental or physical impairment that substantially limits him or her in a major life activity, such as walking, talking, working, or self-care. A person with a
disability may also be someone with a past record of such an impairment, for example, someone who no longer has heart disease but discriminated against because of that history.
The ADA states that employers with fifteen or more employees may not refuse to hire or promote a person because of a disability if that person is qualified to perform the job. Also, the employer must make reasonable accommodations that will allow a person with a disability to perform essential functions of the job. All new vehicles purchased by public transit authorities must be accessible to people with disabilities. All rail stations must be made accessible, and at least one car per train in existing rail systems must be made accessible.
It is illegal for public accommodations to exclude or refuse persons with disabilities. Public accommodations are businesses and services such as restaurants, hotels, grocery stores, and parks. All new buildings must be made accessible, and existing facilities must remove barriers if the removal can be accomplished without much difficulty or expense.
The ADA also stipulates that companies offering telephone service to the general public must offer relay services to individuals who use telecommunications devices for the deaf, twenty- four hours a day, seven days a week.
