BEscape.CStruggle. DFight.答案B解析词义猜测题。根据but的语境可知，有时候海豹也会成功地“逃脱”。4What is Paragraph 4 mainly about?AHow Dr.Pitman and his colleague work.BHow killer whales find seals.CHow killer whales hunt seals.DHow killer whales eat a seal.答案C解析段落大意题。通读第四段可知，主要是通过镜头来告诉我们这种鲸鱼是如何成功猎捕海豹的。.任务型阅读We are going to describe one way to build a rooftop garden that does not even require soil.Four things are needed for a small rooftop garden.One thing is a roof that can support the weight.Another is grass cutting.The third thing is a sheet of plastic in which to spread the cut grass.And the last thing is a box about eight centimetres deep and made out of four pieces of wood.Once you are sure the roof is good，cut and collect some grass.Then lay down the plastic where the garden box will go.The foursided box can be as long and as wide as needed.Place the box on top of the sheet of plastic.Then fill it with the cut grass.Next，add water and walk on the cuttings to press them down.After about three weeks，the rooftop garden is ready for planting.Put the seeds directly into the wet grass cuttings.This garden is a good place to grow peas，tomatoes，beans，onions and lettuce.If the box is deep enough，potatoes and carrots will also grow.It is important to keep the grass wet until the plants begin to grow.When the plants are growing，they will need watering every day，unless there is rain.And they will need some liquid fertilizer.Also，seeds and new plants must be protected from insects and birds.Rooftop gardens are increasingly popular，and not just to grow vegetables.They keep buildings cooler in the sun，so they save energy.They can also extend the useful life of a roof.Rooftop gardens also reduce the runoff of storm water and help clean the air.Plus the add beauty，and give birds and insects in the city a nice place to live.Title：The Building of a Rooftop Vegetable GardenThings needed1.Aims/PurposesRequirementsa roofto 2.support the weight3.flat and strong enoughgrass cut
