Last Saturday, our school had organized an activity to visit the children at a local orphanage(孤儿院）.As one of the volunteer, I took part in it. We took many books as well many kinds of school supplies and toys for the children. 1Hiey were delighted to receive the gifts. In the morning, we played some games with them when we used to play in our childhood. Then we cooked and had a lunch there. In the afternoon, we gave them some performances. Before leaving the orphanage，we had photos take with them and gave them our contact details so that they could keep in touch with one another. Each of us had a happily time. We gave the children our care and help，but in return，they gave us their smiles and love.
If you are afraid of the dark，it’s not a big deal．It’s perfectly normal to feel afraid After all，animals do too. “Fear matters，”says Karen Warkentin，an ecologist．“It’s a good thing，” she adds, “because fear makes you do things that keep you alive.”
Like kids，many animals experience fear and they respond to the feeling in variety of ways．A frightened turtle pulls its head and legs inside its shell．A small fish will swim away when a big，hungry fish approaches．
Some animals respond to fear in ways you might not expect．The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red—eyed tree frogs in Costa Rica.
In this species，female frogs attach jellylike clumps（果冻一样的块状物）of their eggs to the undersides of leaves．The leaves hang on branches that dangle（悬挂）over ponds．After they hatch from the eggs，the tadpoles（蝌蚪）then fall into the water，where they eventually grow into adult frogs.
Tree frog eggs usually grow for 6 days before hatching．If they sense that a hungry snake is about to attack，however，they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim，by falling into the water early，the tadpoles can escape.
If hatching early helps protect red—eyed tree frogs from snakes，you might wonder why their eggs don’t always hatch sooner．It turns out that hatching early brings its own danger．Once tadpoles land in the water，hungry fish and other animals like to eat them too．Staying in their eggs for a full 6 days，then，allows frog embryos（胚胎）to grow big and strong．This extra growth improves their chances of surviving in the water．

BEIJING , March 9 --- The central government will require an additional three years of use for official vehicles for ministers and governors to reduce the costs of purchasing new cars, media have reported.
The new rule has been applied among all Party and government departments nationwide, the Beijing News reported on Tuesday. The new rule has not yet been made public, said Li, a member of the Chinese People’s Political Consultative Conference National Committee.
Under the old rules, the cars used by minister-level officials could be replaced as often as every five years, Li said. These officials will also keep the same cars when they assume new posts, he added.
The new rule also reiterated(重申) that officials ranking below minister-or-governor-levels should not be allocated cars. The cars possessed by their departments should be used on demand.
“It violates the rules for lower-ranking --- even county-level-officials to be allocated cars,” Li said.
Purchases of vehicles for official use have been heavily investigated, as they account for a large expenditure (花费) of public funds every year.
A survey on the Web news www.ifeng.com found 64 percent of respondents believed the new rule will be difficult to carry out because it is related to officials’ interests.
“Local government departments had halted(中断) approvals for requests for such vehicles and had started to work on new quotas(指标) under the new rules,” Li said. “The future reform of official vehicle use will introduce market mechanisms and monetization.”
Premier Wen Jiabao said in the annual government work report on Saturday that expenditures on such vehicles will not increase in 2011 compared with a year ago.
Beijing’s standing deputy mayor Ji Lin last week said the municipal (市政的) government will release the number of vehicles for official use in the capital as early as at the end of this month.
Earlier this month, the Minister of Finance had published a rule regulating the budgets for such vehicles.

2.How often could the cars used by minister-level officials be replaced according to the new rule?
A．Every 3 years. B．Every 5 years. C．Every 8 years. D．Every 10 years.
3.What about the officials ranking below minister-or-governor levels in terms of official vehicles?
A．They can still possess special cars.
B．They can use their own private cars.
C．They can use cars whenever officially necessary.
D．They can be allocated second-hand cars.
4.What is the public’s attitude toward the new rule’s fulfillment?
A．Uncertain. B．Optimistic. C．Indifferent. D．Passive

You’re rushing to work and a man ahead of you collapses on the sidewalk. Do you stop to help? In a study of by-standers, it was found that some people avert their gaze and keep on walking rather than stop and get involved.
“There is a tendency to decide that no action is needed.” says a psychologist. “The first thoughts that pop into your mind often keep you from offering help. In order to take action, you have to work against them.” Here are some common thoughts that might prevent you from helping.
● Why should I be the one? I’m probably not the most competent（有能力的） person in this crowd. You might think someone older or with more medical knowledge should offer assistance.
● What if he doesn’t really need my help? The fear of embarrassment is powerful; no one wants to risk looking foolish in front of others.
● No one else looks concerned- this must not be a problem. We can follow the people around us, but most people tend to hold back their emotions in public.
“If you spot trouble and find yourself explaining inaction, force yourself to stop and evaluate the situation instead of walking on,” says the psychologist. “Then retry to involve other people; you don’t have to take on the entire responsibility of being helpful. Sometimes it’s just a matter of turning to the person next to you and saying, ‘It looks like we should do something.’ Or asking someone if an ambulance has been called and, if not, to call for one. Once you take action, most people will follow you.”
1.Which is NOT the common thought that stops you from helping others?
A．I’m not the very person capable of setting the problem.
B．It looks like we should do something.
C．It must not be a problem as no one else is concerned.
D．He doesn’t really need my help.
2.According to a study of by-standers, what will some people do when a man ahead falls down on the sidewalk?
A．They will call for help and then walk away.
B．They will stop and offer help.
C．They will turn away their eyes and go on walking.
D．They will laugh at him.
3.We learn from the last paragraph that if we spot trouble, ．
A．we should call the ambulance as soon as we can.
B．we should take on the whole responsibility and do something alone.
C．we should stop and evaluate the situation and try to make other people follow.
D．we should turn to other people and ask them to take on the responsibility
4.In order to offer others your timely help, you need to ．
A．ask others for help and call the police
B．get along well with the passers-by who spot the trouble
C．go directly to the police station
D．work against the first thoughts that prevent you offering help
5.The main purpose of the text is to tell readers ．
A．to give others a hand B．to be more competent
C．not to risk looking foolish D．to stop and evaluate the situation
