What are the limits (極限) of human body? The BBC's Focus magazine has some answers.
How cold can you stand?
Normal body temperature is around 37℃. At 35℃ you're unable to write your name. Even walking is very
difficult. At 33℃ you may find it difficult to think, understand and form (形成) opinions properly. By the time
you have cooled to 20℃, your heart would have stopped beating. Limit: 0℃. Ice would form in your tissues
(纖維組織), killing all the cells.
How spicy can you eat?
There is capsaicin (辣椒素) in many foods. The more capsaicin, the hotter the dishes are. If you're healthy
enough, you can survive (存活) eating a teaspoon of pure capsaicin. But you would find it impossible to eat
anything else for a few hours. Limit: 5g capsaicin.
How fast can you run?
The fastest man in the world is Asafa Powell. The runner finished the 100m in 9. 74 seconds in 2007. This
gives an average (平均的) speed of 36. 96km/h. Top runners are at their fastest around 80 metres, so a runner's
greatest speed may reach 43.06km/h. Limit: 43.06km/h.
How loud is too loud?
The loudest sound you can hear is 168 dB (分貝). Sound louder than that may do harm to your ears. The
loudest sound ever recorded was the eruption of Krakatoa (卡拉卡托火山爆發(fā)) in 1883. It was 180 dB, 160km
away.
Limit: 168 dB

任務(wù)型閱讀(10小題*1=10分)注意:每空一詞
Nowadays in school life,a lot of students develop a fear of tests. It’s not because tests are something to be afraid of. Most students are afraid of tests mainly because they don’t have enough self-confidence and they don’t always think they are well prepared. If you follow the tips below, it’s not difficult to overcome(克服)your fear of tests.
People who know that they are not well-prepared are usually those who fear test most. However, most students don’t know when they are truly prepared for a test. As long as(只要) you know that you have studied well and long enough, you have reason to believe that you are well-prepared.
Be confident about yourself. Confidence before a test can bring about two things: either you fail the test and feel as if your confidence was unfounded(毫無根據(jù))or you could actually do well in the test because of your confidence. Some students find that they experience the first result. However, this is only because those students might not have followed the first tip mentioned above. As long as you have studied well, you will be more confident of your chance to succeed in a test. If you feel as if you have not studied hard enough, then you will not be as confident as you should be.
Ask your teacher in advance(提前)about the material that is going to be covered in the test. In this way, you will know what you should prepare for and you can get confidence in the test. But you have to be brave enough to ask. Most students do not ask unless their teacher gives the information first, so make sure that you ask.
You should know that tests are only telling if you have got the knowledge, not how good or bad your IQ is. So, even if you do badly in one test, you should know that there are other tests to come. As long as you think that there is another tomorrow, you can overcome your fear of a test. However, make sure that you are going to prepare well for the other tests.
Fear can be a problem in the process of achieving success. However, with the right attitude(態(tài)度) and preparations, you can overcome your fear of tests by using these tips.
