Environmental DNA can be used in two ways. One is to identify the creatures that live in a certain place. The other is to confirm the presence or lack of a specific creature.

Caren Goldberg is one of the first biologists in the northwestern United States to take the technology from the testing stage to actually using it. She sees e-DNA as a way to get answers more efficiently, and with less destruction compared to traditional survey techniques. Until recently, scientists depended on diving deep, netting or using an electric current to temporarily catch fish.

This newer way to identify what lives in the environment is becoming popular around the world. Animal experts in Vietnam are using the e-DNA to find the last, wild Yangtze giant softshell turtles. One researcher on the Caribbean island of Trinidad is using the sampling technology to find endangered golden tree-frogs. And in Madagascar, it is being used to identify amphibian (兩棲動(dòng)物) diseases.

Ms. Goldberg has used e-DNA testing to confirm the local extinction of a leopard frog in the American state of Idaho. She has also been asked to document the spread of the New Zealand mud-snail in the state of Washington. The creature has been found in lakes and other waterways across the state.

Scientists working with the technology say they do not expect robots to replace field biologists anytime soon. But the old-fashioned field work could soon be more targeted.

My mother reacts very sensitively to my feelings. That is typical of Alzheimer’s patients. When I visit her, feeling hectic and tense, she reacts immediately, takes on my mood, and becomes nervous and negative. But when I appear cheerful and attentive, she is happy. This has taught me to pay more attention to my own feelings when I am with other people.

Through the illness my mother has developed a childlike tactlessness (不得體). Eating out in restaurants, for example, is a bit embarrassing when she shouts at the waiter that the food is so bad or talks about people at the next table in a loud voice. Of course I make sure that my mother doesn’t hurt anyone, but I’ve stopped complaining about others and have become more tolerant.

I have also learned that everything has special value. When my mother got sick I didn’t want to burden my two daughters with it. They are young and have enough going on with their education, and starting their careers. I felt that it was simply my job as my mother’s daughter. The most wonderful discovery I’ve made through my mother’s disease may be that my children not only offer to help me, but that they take care of my mother on their own actively. They visit her often, play cards with her, and look at photo albums together with her. It shows me that it’s all worth it.

The best advice I received in my childhood was from my dad. He always gives me some advice, but I seldom took them seriously. One day he encouraged me to participate in a speech competition. So I signed up and after the competition, I did my best to be full prepared. But the moment when I stood on the stage, I was such nervous that my mind completely went blank.

The experience of lose a competition was really painful. Then, my dad said, “My son, life is like battlefield. You have to lose many time to win the final victory.” Thanks for his advice, I will never give up when I do anything.

When you don't have a greenhouse or enough room on the balcony for a few pots, you can still grow【1】(you) a few tasty home-grown tomatoes in hanging baskets ans window boxes if you stick to short varieties. I’ve even heard of these being grown by canal-boat【2】(owner) on their cabin（船艙）roof, since they’re short enough to fit under the bridges.

You might have trouble【3】(find) suitable plants later but there’s still time to raise your own form seed if you start straight away. Look for small “tumbling”（下垂的）varieties such 【4】Totem and Gartenperle. If you live in a【5】(nature) cold area, it’s worth looking out for a unique variety called Sub-Arctic Plenty, which has【6】similar size and habit but performs better than most in cooler climates.

All of these will make short plants ideal for pots; they can【7】(place) anywhere with limited space, as long as it’s sheltered and【8】 (sun). What’s more, tumbling tomatoes are very easy【9】(grow)because they don’t need to have any side shoots removed and【10】do they need more than a few short sticks for support. Simply water, feed and pick.
