The movement was so sudden(23)________several passengers felt sick and had to use airsickness bags.(24)________you might guess,that’s not good thing to happen in a narrow space because it only serves to increase the discomfort of the situation.

2019届上海市各高中名校高三英语题型分类专题汇编--阅读理解B篇--老师版(带答案已校对珍藏版)
III. Reading Comprehension Section B Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read. B Kettlebells do not hurt people. People do. A kettlebell will get your respect – the easy way or the hard way. Here is the easy way. 1. Get a medical clearance. Get clearance, especially from an orthopedist and a cardiologist. The latter is no joking matter, since kettlebell training can be extremely intense. 2. Always be aware of your surroundings. Find a training area with a non-slippery surface on which you are not afraid to drop a kettlebell. The area must be clear of objects you might trip over – including other kettlebells – or that you might hit with a kettlebell. There should be no people or animals in a radius where you could injure them. 3. Train barefoot or wear shoes with a flat, thin sole and room for the toes to spread. Training barefoot is superior for health and performance reasons. If you must wear shoes, wear Converse Chuck Taylors, Vibram Five Fingers, or similar shoes that have thin soles and do not pinch the toes together. You have sensory receptors on the bottoms of your feet that make you stronger and improve balance and coordination. Wearing traditional shoes diminishes the ability of these receptors to work properly, and therefore inhibits performance and can increase the risk of injury. Go native. 4. Never contest for space with a kettlebell. Do not try to save a rep that has gone wrong. Guide the kettlebell to fall harmlessly, and move out of the way if necessary.
