It is easy for us to tell who our family members are, but do plants recognize(识别) their own family? Some do, scientists say, according to a report by Science News in early 2010.

Guillermo P. Murphy and Susan Dudley are two plant scientists from McMaster University in Hamilton, Canada. They did a few experiments with Jewelweeds, a kind of flower that grows in wet, shady spots. They found that the flowers seem to know their own flower family. In their experiments, Murphy and Dudley planted jewelweeds in pots with either siblings or strangers.

When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response(反应)suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food. Jewelweeds usually grow in the shade, where sunlight is not enough.

When jewelweed seedlings(幼苗)were planted with siblings, they grew a few more branches than they usually would if they were alone – but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete.

According to the Science News report, Jewelweeds are not the first plants that plant scientists have studied for family recognition. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach – where it may be hard to get fresh water. In that experiment, the scientists found that when sea rockets were planted with siblings, they tolerated each other. But when they were planted with strangers, the sea rockets reacted by working extra hard to grow lots of roots.

Dudley says this just because sea rockets, on the beach, get plenty of sun but struggle for water – so when they’re threatened, they compete for water. Jewelweeds have plenty of water but have to compete for sunshine, so they grow more leaves.

Open today’s newspaper. What do you see? Ads! Look through a magazine. More Ads! Turn on TV, still more ads! Everywhere you look, someone has something to tell.Here are some ways ads get us to buy.

Some ads use famous people. Stars are paid to sell a product. Think about it. Do they really know about medicine? Do they know about soft drink? These people may be famous. But they may not know about what they are selling.

Some ads make you think you’re getting the word of an expert. They say, “Doctor said.” A man in a white coat comes on TV. He looks nice. “I use bright and white,” He says. This man looks like a doctor. But he is an actor. He has been paid to sell this product.

Does soap have anything to do with a pretty child? Not much. But ads may show their product with something nice such as the sun, the flowers and so on. Such an ad is about feelings rather than facts.

Ads are full of strong words, and words like “new” and “improved” have power. They can help a produce sell. The soap may be called “Spring Rain”. A car may be called “Tiger”. Strong words work on our feelings.

Some ads make promise. But can they keep them? No.

Some ads use our fear of being too late. “Buy now!” They say, “Selling ends soon.” Check to see if this is true. Don’t hurry. Take time to think.

All ads hope we will buy something, do something, or think in a certain way. Know what ads are doing. Ask questions to yourself. Don’t let their words and pictures fool you.

1.Some stars appear in the ads because_________.

A．they know every product well

B．they are famous

C．they are all experts

D．they all like white coats

2.According to the passage, we know that “Spring Rain” is the name of ______.

A．tell us a story B．always make us strong

C．sometimes fool us D．keep promises
