19．A few days ago, I was floating ________ in a cloud in Hangzhou. （comfort）
【答案】comfortably

20．It’s important to brush your ________ at least twice a day. (tooth)
【答案】teeth
【详解】句意：每天至少刷牙两次是很重要的。tooth“牙齿”。根据“brush your”可知，空格处应用名词，表示“刷牙”，此时“牙齿”应用其复数形式teeth。故填teeth。
21．I was dirty after my journey, so they took me to a water treatment ________ . （work）
【答案】works
【详解】句意：我在旅行后很脏，所以他们带我到了一家自来水厂。根据句意及句子结构分析可知，空处应为名词，且意为“工厂”时，work用复数形式works。故填works。
22．Pollution makes things dirty and ______ . We must fight against pollution.（health）
【答案】unhealthy
【详解】句意：污染使事物变得很脏和不健康，我们必须与污染作斗争。根据“dirty and...”可知，空处需填入形容词。再根据“Pollution makes things dirty”可知，此处是指不健康的，其英文表达为unhealthy。故填unhealthy。
23．Comic books are so ______ that a lot of students read them till night without having dinner. (attraction)

【答案】impatient
【详解】句意：这个小男孩很不耐烦，他从来不回答你两次。is后接形容词作表语，根据“he never answers you twice”可知，从不回答两次可以看出他是一个不耐烦的人，impatient“不耐烦的”，故填impatient。

四、句型转换
Rewrite sentences as required. (按要求改写下列句子，每空限填一词。)

31．choose to, convenience,  use,  because of, payment methods, an increasing number of, cashless, people (连词成句)   
__________________________________________________________________________________________________________________

【答案】26．     didn’t     put    27．     whether     they    28．     has     it    29．     How     often    30．     won’t     until    31．An increasing number of people choose to use cashless payment methods because of convenience.

【解析】26．句意：少先队员的领队在校园里张贴海报，宣传节电的重要性。
根据原句中的主语leader动词put up可以确定句子用的是一般过去时，变成否定句需要加助动词did，与not可以缩写成didn't，put的过去式和原形是一样的，所以这里填didn't put。
27．句意：“我们去上海迪斯尼乐园春游好吗？”学生们问张先生。
根据句意理解可知，这里直接引语是一个一般疑问句，所以变成间接引语应该用宾语从句一般疑问句的引导词if/ whether来引导，而宾语从句中有or not，所以确定只能用whether，而直接引语的主语是第一人称we，宾语从句的主语是the students，根据直接引语转换成间接引语“一从主”的规律可知，宾语从句的主语应该与the students一致，应该用they来代替，所以这里应该填whether they。
28．句意：没有人类的好奇心和创造力，科学技术很难有如此大的进步。
根据反意疑问句的原则“前肯后否，前否后肯”可知，句中有hardly否定词，所以反意疑问句部分要用肯定形式，而原句总的是现在完成时，所以反意疑问句部分助动词应该用have/ has，而原句的主语是不可数名词，所以应该选择has，主语应该用代词it代替，所以这里填has it。
29．句意：每年举办一次慈善活动，呼吁学生向雷锋学习。
根据划线部分yearly可知，这里提问的是频率，英语中提问频率的词用how often，所以这里直接填How often。
30．句意：一个人永远不会知道，只有在他陷入绝境之后，他才能走多远。
根据句意理解可知，这里需要转换的是只有……才，英语中可以用not…until直到……才来代替，而原句中用的是一般将来时，所以与not可以缩写成won't，所以这里填won't until。
31．句意：越来越多的人选择使用无现金支付方式是因为方便。
choose to是选择,convenience是方便，use是使用，because of是由于, payment methods是支付方式, an increasing number of是越来越多的, cashless是没有现金的, people是人们，综合起来，这句话应该表达的是：越来越多的人选择使用无现金支付方式是因为方便。所以应该连接成：An increasing number of people choose to use cashless payment methods because of convenience.

五、阅读单选


Do you dream of being Iron Man? Do you watch him in some famous films? Just put on a new kind of clothes and you will become very strong like him!

Scientist Glenda says the exoskeletons will help him or her find a way and get out fast. It’s also a very important advantage.
“The cost of a full-body exoskeletons is about $45,000” says Accenture’s Mr Spragg. But the price will come down. Maybe people won’t spend lots of money on them in the future. “I think people can buy them in every shop.” one Scientist -California’s Suit X says.

And then, they will be warm when people are cold, and cool when people are hot. If someone gets lost, they can help too!”可知，外骨骼可以帮人们搬动重物，可以帮助残疾人走路，可以调节温度，也可以帮助迷路的人指路，所以一共有4个有点，故选C。

八、阅读回答问题
根据短文内容完整回答下列问题。
Living on the ISS
Hello everyone, my name is Jessica Meir. I am an astronaut. I work on the International Space Station(国际空间站，缩写为ISS) as a flight engineer. Today, I will tell you something about what life is like on the ISS.
The ISS has over 425 cubic meters(立方米) of living space. I work here with astronauts from the United States, Russia, Japan, Canada and several other European countries. When we are on the ISS, we have to follow a detailed daily schedule. It tells us when to get up, eat, exercise, work, relax and go to sleep. We spend about two hours each day exercising. Without regular exercise, we would lose a certain amount of muscle and bone due to the microgravity (微重力) environment in space.
The food we eat is specifically designed for space missions. Some foods, such as cakes, can be eaten in space just the way they are eaten on the Earth. But some other foods are real challenges. For example, when you’re in space, you can’t shake salt onto food, because the salt would float away. As a result, we have to use special liquid salt.
When we are not busy doing experiments on the ISS, we can relax and have fun in a variety of ways. Like most of you, we listen to music, read books, play cards, watch movies and talk with our family members.
As you can see, the microgravity environment in space brings many challenges that don’t exist on the Earth. Would you like to live for some time on the ISS?
Yours sincerely,
Jessica Meir
