“Life’s a long, long journey() more manageable, divide your goals into smaller tasks. For
example, if you want to reach a main goal in five years, set a three-year goal, a one-year goal, a three-month goal and a one-month goal. Then create a daily To-Do List of things that you should do today. When a goal is achieved, take the time to enjoy your success. This helps you build the self-confidence. Remember, your goals can change as time goes on. But be sure your goals are things you hope to achieve, not what your parents, family or teachers want. 小题1:Is life a long journey according to the passage? 小题2: Why do you need to set your life goal? 小题3:What should you consider when you set a family goal? 小题4:How can we achieve the main goal easily? 小题5:What does the writer want to tell us?

根据以下资料,回答{TSE}题。 Graphene’s Superstrength Big technology Comes in tiny packages.
New Cell phones and personal Computers get smaller every vear,which means these electronics require even smaller Components on the inside.Engineers are 100—king for Creative ways to Build these Components,and they’ve turned their eyes to graphene,a super—thin material,made of Carbon,that Could Change the future of electronics. This year,s Nobel Prize for Physics has Been awarded to Andre Geim and Kostya Novoselov from the University of Manchester,UK for the Discovery of graphene.Graphene isn’t just small,it's “the thinnest Dossible materialin this world.”says Novosetov.He Calls it a “wonder material.”It’s so thin that you would need to stack about 25,000 sheets just to make a pile as thick as a piece of ordinary white paper.If you were to hold a sheet of graphene in your fingers,you’d have no idea Because you wouldn’t Be able to see it. Carbon is one of the most abundant elements in the universe.Every known kind of life Contains Carbon.Graphene is a sheet of Carbon,but only one atom thick.You Don’t have to look far to find gra—phene—it’s all around you. If you want this high—tech wonder stuff,all you need is a pencil,paper and a little adhesive tape. Use the Dencil to shade a small area on the paper,and then apply a small piece of adhesive tape over the area.When you pull up the tape,you’11 see that it pulls up a thin layer of some of the shading from your pencil.That layer isCalled graphite,one of the softest minerals in the world. Now stick the same piece of tape on another sheet of paper and pull the tape up—there shouldBean even thinner layer,this time left on the paper.Now imagine that youDo this over and over,until you get the thinnest possible layer of material on the paper.This layer would Be only one atom thick. and vou wouldn,tBe able to see it.Graphite is made of layers of graphene.so when you get to the thin— nest possible layer,you’ve found graphene. {TS}What would Change the future of electronics according to engineers?

A. Personal Computer.

B. Big technology.

C. Graphene.

D. Creative ways.

Task 1

Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice.

People who work night shifts are constantly fighting against an "internal clock" in their bodies. Quite often the clock tells them to sleep when their job requires them to remain fully awake. It's no wonder that more accidents happen during night shifts than at any other time. Light therapy (阳光治疗法) with a bright light box can help night-shift workers adjust their internal clock. However, many doctors recommend careful planning to help improve sleep patterns. For example, night-shift workers often find it difficult to sleep in the morning when they get off work because the body's natural rhythm (节律) fights back, no matter how tired they are. Some experts recommend that night-shift workers schedule two smaller sleep periods—one in the morning after work, and another longer one in the afternoon, closer to when the body would naturally need to sleep. It's also helpful to ask friends and family to cooperate by avoiding visits and phone calls during the times when you are sleeping.

Night-shift workers are those who_________.

A.have to rely on their internal clock

B.need to re-adjust their clock

C.fall asleep late at night

D.have to work at night

听音频,回答题

Have you ever noticed that while it"s pretty easy to tell your dog is sick, it"s much harder to know how your cat or bird are feeling? Welt, before you start asking your dog why it can"t be more 26 like animals half its size, it"s probably worth 27 each animal"s place in the food chain. You see, the lower down the food chain you are, the more important it is for you to hide any sign of illness. Obvious illness or pain28 as red flags for predators. You may as well wear a sign saying, "Easy meal, guys. Come and get me."

Now, even small dogs are 29 programmed to function like predators,which 30 considering they are close relatives of wolves. And birds——you can probably 31 why the only way you"d find out your bird is sick is when it dies.

The situation with cats,32 dogs and birds, is much more interesting. On the one hand, cats are predators, but on the other, they"re small enough to be prey.

So how can you tell if your smaller pets need 33 attention? For one thing,trust your feelings. No one knows your pets like you do, so if you notice even very 34 changes in habits and behavior, you may want to have a vet look them over. For a cat, other signs of illness might be that it has stopped grooming, is losing weight,35more or less than usual, or missing the litter box.
