But as a matter of fact,  Grade 12 students in Canada are just as busy and pressured as students in China. In Canada,  students have to pay equal attention to all the tests and assignments,  as every little evaluation will directly affect their final grades. To ease some of the stress from the important courses,  like mathematics and English,  students will often choose one or two fun courses in the last year of high school. Those classes can give students a fairly excellent final grade. Take me as an example,  the classes I am attending this semester include advanced functions,  graphic design and history. All of them are really important to me,  which means I have to pay more attention to them. In order to get enough elective credits to grade,  I chose a relatively easy course,  nutrition and health. This course is aimed at helping students develop a healthy lifestyle and diet. The biggest highlight of this course is that students can experience cooking and baking,  which I believe is the reason why there are a large number of students on the waiting list.  Usually,  there are one or two food labs every month. Teachers always let students decide what they want to cook or bake. Students are divided into four groups with six people,  and teachers are given the recipe beforehand. After attending this class for more than three months,  I believe it’s not as easy as others think it is because it’s an interdisciplinary(跨学科) course that requires basic knowledge of science,  humanity and even culinary art. Despite these kinds of courses not being as demanding as others,  we can still learn a lot from them. Some people might think they’re “mark-boosting(促进分数的)” courses that don’t need to be taken seriously. But I consider them to be a unique way to ease the tension or other schoolwork. 1. Why do Grade 12 students in Canada take fun elective courses? A. To pass the free time. B. To put theory into practice. C. To adopt a healthy lifestyle. D. To get relief from schoolwork. 2. It can be learned from Paragraph 4 that Canadian elective classes are 　　　.  A. easy but boringB. diverse but stressfulC. practical and beneficialD. interesting and inspiring3. Which of the following might be the best title for the text? A. School Life in Canada. B. Canada’s Elective Classes. C. Educational System in Canada. D. Tips for Choosing Elective Classes. 2　　It’s been a long,  wet winter. As thousands of people died from COVID-19,  improving our immune system has rarely felt more urgent. “When you come into contact with a virus you’ve never met before, ” says Sheena Cruickshank,  a professor of immunology at the University of Manchester,  “you’ve got various barriers such as skin,  microbiome and so on to try to stop it getting into your body. ” If a virus breaks these defenses,  it has to deal with our white blood cells,  or immune cells. “However,  our immune systems may have blind spots,  where our immune response might won’t recognize certain bugs, ” says Cruickshank,  “Personally,  my immune system is not necessarily very good at seeing colds. ” But a healthy lifestyle will secure solid defenses. Cruickshank recommends “eating a more varied diet with lots of high-fiber foods”. Being vegetarian isn’t a necessity for microbiome health,  but the more plant foods you consume,  the better your body is. To be immunologically fit,  you need to be physically fit. “White blood cells can be quite inactive, ” says Prof.  Arne Akbar,  the president of the British Society for Immunology,  “Exercise mobilizes them by increasing your blood flow,  so they can do their security jobs. ” Apart from this,  exercise can reduce stress,  which is next on our list of immune-improving priorities. Stress hormones(激素) can weaken immune function. If you have had it,  the virus never completely goes away. “During periods of stress, ” says Akbar,  “it can reactivate and then we get sick. ”Exercising and eating well will have the likely knock-on effect of helping you sleep better,  which is a bonus because a tired body is more sensitive to bugs. “If you’ve got a regular sleep pattern,  you have natural body rhythms and everything’s fine. If they go out of order,  then you’ve got problems. ” says Akbar. 1. According to Paragraph 2,  when the barriers fail in preventing a virus entering your body,  　　　will come up next.  A. skin　　　　　　　   B. bloodC. microbiomes     D. immune cells2. Why does the author mention by “my immune system is not necessarily very good at seeing colds”? A. To emphasize that our immune system is not always reliable. B. To tell us that Cruickshank doesn’t lead a healthy life. C. To stress that a healthy lifestyle helps improving immune system. D. To indicate that catching a cold is not a terrible thing. 3. What does the underlined word “them” in Paragraph 5 refer to? A. Microbiomes. B. White blood cells. C. People doing exercise. D. Stress hormones. 4. What can be a suitable title for the text? A. How to boost your immune system to avoid COVID-19? B. Why does COVID-19 have a bad effect on our health? C. COVID-19:  Improving our immune system. D. Immune system:  the best way to deal with COVID-19. Ⅴ. 语法填空　　Here are some 1. ________ (suggestion) for you,  which may help you enjoy your school life better.
