【分析】
解题时需先明确方框内频率副词的含义：always（总是）、usually（通常）、sometimes（有时）、seldom（很少）、never（从不），再结合每个句子的语境判断合适的副词，注意句首单词首字母大写的规则。
1. 句子描述英语老师上课常带甜笑，对应“总是”；
2. Tina每天早起，对应“从不迟到”；
3. 每周仅锻炼一小时，对应“很少锻炼”；
4. 句子开头表“有时”，需大写首字母；
5. 睡前固定读半小时，对应“通常”。
【解析】
1. 句意：我的英语老师上课总是带着甜美的微笑，我们都喜欢她。always表示“总是”，符合语境，故填always；
2. 句意：Tina每天早上早起，所以她上学从不迟到。never表示“从不”，符合逻辑，故填never；
3. 句意：福星很少做运动，每周仅一小时。seldom表示“很少”，匹配“only one hour a week”的描述，故填seldom；
4. 句意：有时，Lisa想在学校图书馆做作业。sometimes表示“有时”，位于句首需大写首字母，故填Sometimes；
5. 句意：Mary通常睡前读半小时，这是个好习惯。usually表示“通常”，符合“好习惯”的常规行为，故填usually。

Ⅲ.阅读短文,完成下列任务
If you fly across several time zones, you may have jet lag(时差反应). You ar- rive in a new time zone, but your body is still living on the time in the old time zone. You may be ready for dinner at midnight, and you may want to sleep all day.
People have jet lag because all living things have a biological clock(生物钟). For example, plants begin to work at sunrise. When winter comes, birds fly to warm places. Some insects like bees also seem to set their alarm clocks to look for food.
Some scientists did an experiment(实验) with bees in Paris. They put out sugar water at 4:00 p.m. every day, and the bees came to drink the water at ex- actly(准确地) the right time. Then the scientists put bees in a dark room. The bees still came out at the same time. Lat- er the scientists took the bees to New York. The bees came for the food at the right time again, when it was only 10:00. a.m. in New York. Their bodies were still on Paris time.
Humans have a biological clock too. It tells us when to sleep and eat. Our bodies are controlled by a biological clock, but we can learn to adjust(调整) it to different time.
任务一:根据短文内容,选择正确的答案。
()1. How many examples of the bio- logical clock does the writer show in Paragraph 2?
A. Two. B. Three.
C. Four. D. Five.
()2. When did bees come out for food in New York?
A. At 10:00 a.m. (Paris time).
B. At 4:00 p.m. (Paris time).
C. At 4:00 a.m. (New York time).
D. At 10:00 p.m. (New York time).
()3. What is the purpose of showing the experiment with bees?
A. To explain how bees set their alarm clocks.
B. To tell us that bees look for sugar water to live.
C. To prove that living things have a biological clock.
D. To show that living things can reset their biological clock.
()4. What can we learn from the passage?
A. Humans can adjust their biological clock.
B. The biological clock isn't useful at all.
C. Bees couldn't tell the time in the dark room.
D. Some people have jet lag because they are weak.
