B.It's sometimes cold ,and sometimes hot
C.Hokkaido in Japan is a place with a lot of rain
D.people can enjoy beautiful scenes in gardens and parks
Japan's rainy season called tsuyu（梅雨）usually begins in early May in Okinawa.In other areas,it runs from early June to mid July.Hokkaido,the northern part of Japan,generally does not have tsuyu,although some parts experience cloudy and cold days that look like tsuyu in early summer.Its weather seems to be nicer than other areas of Japan.
The weather during tsuyu is changeable.It is important to get ready for the rain anytime.Although it's usually rainy with lower temperatures,sometimes there is less rain and can be hot.It often brings heavy rain in Kyusu.So if you are visiting the South of Japan,you need to take an umbrella with you.
The main problem during the rainy season is humid.People usually become annoyed by it.Taking a shower often helps you stay comfortable.Also,things are more easily to become moldy.If you are staying in Japan ,it is important to put your clothes and bedding in the open air when it's sunny.As lots of food goes bad easily during this season,it's also important to watch out what you eat.
Although tsuyu is an unpleasant time,the rain is very important for growing rice.Also,there are many pretty flowers that come out at this time.You can enjoy the colourful flowers in many gardens and parks.Viewing pretty flowers makes us feel relaxed on the unpleasant days.

From the passage,we know people can enjoy beautiful scenes in gardens and parks during tsuyu.
从文章中我们知道,人们可以在梅雨季节去花园和公园欣赏美景
答案：D
再问： 能不能解释一下B错在哪里？？？
再答： 文中只说The weather during tsuyu is changeable. Although it's usually rainy with lower temperatures,sometimes there is less rain and can be hot. （梅雨期间，天气多变。温度较低时通常会下雨，但有时雨水较少，却热很。）并没有说“时冷时热”。
再问： 可是答案是B
再答： 不管答案是哪个，文中没有提到“冷”，用排除法选择，只有最后一句话在答案中“You can enjoy the colourful flowers in many gardens and parks.Viewing pretty flowers makes us feel relaxed on the unpleasant days.”
