One of the most common things we hear people say is "I had one of these plants once but it died", and the first thing we ask is "How were you watering it?"

Watering is one of the most important aspects of succeeding with Tillandsias(铁兰), and one of the most misunderstood. Because their common name is Air Plants, people tend to think of these plants as needing little or no water(as living on air). This is the    1    ( big) mistake you can make. Tillandsias need water.    2    they can survive for long periods of drought, they are not growing in these conditions. They are just trying to survive, and will eventually die    3    water is scarce for too long.

Your plant will also rot and die if     4    (leave)wet for too long. Basically this means your plant wants water, but needs to dry out completely before    5    ( water) again. Plants should be given enough light and air circulation to dry in no longer than 4 hours. It's best    6    (water)your plants in the morning so they dry by nightfall.

Humidity is not    7    source of water for your plant. Tillandsias    8    only obtain their water if it is on their leaves, in nature through dew, fog and rain. Humidity only delays the drying process. Get to know your plant and handle the leaves. After you water them, the leaves will feel stiff and full of water, when in need of water they will be softer to the touch and the plant will be lighter in color.

Generally speaking, water quality is not important to Trillandsias. They do not tend to show water spots and are basically only susceptible(易受……影响) to pH8 or higher, or too much salt. Artificially softened water has too much sodium(salt) for Tillandsias and should not be used    9    it will slowly cause die back(枯萎). Distilled water is too pure and will actually pull nutrients out of the plant tissue,     10    ( cause) death.

【推荐2】If you go out to the fields at night spring or summer, you can hear singing    1    (happy)here and there. It seems as if they were performing a field concert.

The frog is a beneficial creature that does good to human beings. They can catch fast-moving insects. Each frog eats a large number of pets that are harmful to crops. This little creature is regarded     2    the natural enemy of pests.

But now the number or frogs    3    (become)smaller and smaller. This is    4    they are killed and put    5    the table as a delicious dish by their chief enemy, human beings. It is cruel, isn’t it? The cause of the rapid    6    (reduce)of frogs is that farmers use pesticide(杀虫剂)to kill pests ,and then frogs get     7    (kill)as a result of eating the poison-killed insects.

Something must be done without delay    8    (save)frogs. If we don’t punish those     9    sell and kill frogs to make money, then one day all of us     10    (punish)by nature for failing to save frogs.

You may have heard of the old expression “Go tell it to the bees". But     1     exactly does it mean?

There was a time when almost every British family who kept bees     2     (follow)this rather strange tradition. Whenever there was a death in the family, someone had to tell the bees of the terrible loss     3     had happened to the family. Failing to do so often resulted in further losses. Traditionally, the bees were kept up to date with not only deaths but all important family     4     (matter)including births, marriages, and long absence due to journeys.

The practice of telling the bees may have    5     (it)origins in Celtic mythology (神话） that held that bees were the link     6     our world and the spirit world.

But for bees and humans, their relationship goes beyond superstition(迷信）.     7    （actual), bees help humans survive.70 of the top 100 crops that feed 90% of the human population rely on bees for pollination(授粉）.Without them, these plants would stop    8    （exist) and with it all animals that eat those plants. This can have a     9     (harm)effect on the food chain. The act of telling the bees stresses this deep     10     (connect)humans share with the insect and nature generally.
